Women, Men, Fibre and Cholesterol

Wednesday, October 22nd, 2008

-   54% of women said they know exactly how much fibre they need, and what type of fibre is best for them, compared to 44% of the men polled.
-   Women (67%) are more aware than men (60%) about the benefits of products containing 100% psyllium fibre.
-   69% of men say they would take a fibre supplement with proven cholesterol-lowering benefits as a proactive measure, compared to 65% of women.
-   In the past year alone, 60% of all male respondents have had their cholesterol level checked, while only 52% of women passed the same test, even though 51% of women know their family has a history of high cholesterol, heart disease, heart attacks and stroke, compared to only 40% of men.

Most Canadians Agree: Fibre Is Important

Tuesday, October 21st, 2008

A recent survey by Metamucil and Ipsos Reid reveals that 96% of the respondents across Canada agree: fibre is an important part of a healthy diet. Yet despite this general knowledge, less than half (49%) actually know just how much fibre they need, and what kind of fibre is best for them. A similar discrepancy appears when women were asked about their cholesterol: 36% have no idea how high or low their cholesterol level is, even though a shocking 51% have a history of high cholesterol, heart disease, heart attack or stroke in their family. Of course, when women were asked if they could exactly pinpoint their current weight, 78% admitted they could. As a population, it appears we are far more concerned about pounds than cholesterol
points.

To help women look beyond their external beauty and take charge of their inner health, Metamucil, Canada’s leader in fibre therapy, teams up with well known television star and health advocate Brenda Strong to introduce the 30-Day Challenge. “Beauty isn’t only skin deep. It’s important that all women pay as much attention to their insides as they do to their outsides,” says Strong.

Women can start on a path to a healthy lifestyle by taking the Metamucil 30-Day Challenge, and applying these four simple steps:

-   Take Metamucil daily! Be sure to take Metamucil Powders or Capsules Plus calcium as directed in the Cholesterol Lowering Dosing Instructions found online.
-   Follow a low-fat diet! Don’t forget to use the healthy habits listed online in the How Do I Get Lower Cholesterol? section as a guide for the next 30 days.
-   Get active! Develop and stay committed to an exercise routine that is safe, fun and that can be used regularly.

“With heart disease directly impacting the lives of my loved ones, my personal connection to heart disease led me to become a part of the 30-Day Challenge program. In order for women to understand their risk, they must get a cholesterol screening and know their number,” says Brenda Strong. “Metamucil provides women with tips and tools to help them lower their cholesterol and live a healthy lifestyle. I successfully lowered my cholesterol by taking Metamucil and want to encourage other women to try and do the same.”

When used in conjunction with a low-fat diet and regular exercise, a dietary fibre supplement made from psyllium husk, as found in Metamucil powders and capsules plus calcium products, can help reduce mild to moderatelyelevated cholesterol levels

Take Control Of Cholesterol To Protect Heart Health

Thursday, August 28th, 2008

Heart disease is an issue that gets much attention in the media, and for good reason. It is the leading cause of death for men and women in the United States. Heart disease is a major issue, and a variety of risk factors come into play. Today I want to narrow the subject down on cholesterol, this is one of the graten still manageable-the most risk factors for cardiovascular disease.

Make it a point to discuss in depth with my cholesterol patients, because anyone can control over their health, when it comes to keep cholesterol in a healthy range. It is true that a tendency towards high cholesterol can be inherited genes, but there are also a lot of opportunities in such cases.

Making the effort is worth it: Studies have shown that lowering cholesterol decreases your chance for developing heart and Gefakrankheiten. In addition, the people who currently have heart disease can reduce their risk of suffering nonfatal heart attacks and death from heart disease by lowering cholesterol levels.

Healthy answers to lower cholesterol

To help fight heart disease, I have combed through the latest research results and the list of natural ways to start lowering cholesterol today.

Vitamins - Looking for a formula vitamin supplement that helps your cholesterol ratio in the normal range. Vitamin E and selenium are two essential nutrients for health cholesterol. Vitamin B3 (niacin) is another nutrient believed to lower LDL, the bad cholesterol.

Herbs and spices - The seeds and leaves of Fenugreek May lower total cholesterol. Make sure to increases of at least 500mg of this potent Herb. Guggulipid, the chewing gum myrrh resin of a tree in India may also lower LDL. Other studies suggest that artichoke leaf extract, yarrow, holy basil, ginger, turmeric, garlic, rosemary and cholesterol-lowering effects.

Quit Smoking - Smoking causes high cholesterol, smoking, but may good, HDL, cholesterol and reduce the risk of developing heart disease.

Dietary Fiber - foods from plants, particularly oat bran, barley, psyllium seeds, flax, apples, citrus fruits and legumes, contain soluble fiber, cholesterol favourable impact levels.

Phytosterols - These links can be found in small amounts in plant foods with intestinal absorption of cholesterol. Get them in vegetable oil spreads like Promise, Benecol and Smart Balance, on vegetable oil based salad dressing and fortified foods, such as Minute Maid Heart Wise orange juice and CocoVia chocolates.

Soy Foods - tofu, tempeh, soy milk, Edamame soy and nuts are just some of the soy products, has been shown to lower LDL cholesterol.

Omega-3 fatty acids - This cholesterol-lowering nutrients found in walnuts, flax seed and fish. The aim for 2 servings per week of salmon, mackerel, herring, tuna or sardines. Fish oil capsules are another way to your daily diet dose.

Cutting down on saturated fatty acids that LDL cholesterol in check. People with heart diseases should be to eat less than 200mg of cholesterol from animal products (meat, milk, eggs), and those who wish to maintain healthy cholesterol levels should stay under 300, according to the American Heart Association. Trans-fats, increase bad LDL, cholesterol and reduce good, HDL, cholesterol should fully exercise avoided.

Apart from the many health benefits in connection with the exercise, moderate physical activity can increase the cholesterol.

Now good that you know how many simple options for the management of cholesterol health, I am sure you are curious, they’re off! Work with your doctor and not be discouraged. As long as you practice moderation by diet, add some useful vitamins and herbs, remain active and every day, you can be well on the way to a healthy number on your next cholesterol screening.

How to Fight Cholesterol

Monday, August 4th, 2008

Dr. Helen is having some cholesterol hell. She wants to keep her LDL cholesterol low and HDL cholesterol high, and having suffered a heart attack in the past this is of the utmost importance. The product she was using was Benecol Smart Chews, which, judging by the nutrition facts, don’t seem to have anything particularly wrong with them. It uses plant sterols, proven to lower LDL cholesterol in the human body. Yet her LDL cholesterol and triglycerides level went up. What gives?

Whatever the reason, cholesterol is something you should try to keep in check whether young or old. Sometimes, triglycerides and LDL cholesterol come from crazy places you wouldn’t even think of. Below are my tips for getting your cholesterol under control through the use of a good diet, exercise, and supplements.

Avoid Processed Foods and Artificial Sweeteners

This is so hard to do nowadays because almost everything is processed and almost everything has corn syrup in it (even the chews!). Processed foods like corn syrup — and even white bread and white pasta — are turned into glucose (sugar) rapidly by the body. Excess sugar that your body doesn’t use fast enough will be turned into fat. In this case, most often these foods will be turned into triglycerides, a kind of fat that is easy to burn off but is detrimental to your health.

Buy truly whole grain products whenever possible to avoid this affect on the body.

Limit Your Alcohol Consumption

Certain alcohol beverages, such as beer and especially wine, have been shown to have incredible health benefits in moderation. A couple glasses of wine a day is no problem. However, when you drink alcohol, the liver prioritizes the metabolism of alcohol over other substances such as glucose. This results in even more glucose than usual being converted into triglycerides. This will happen especially when drinking cocktails that involve fruit juices and syrups. This is especially a warning to all the college students out there!

Eat Your Fiber

This can’t be stressed more. Fruits, vegetables, and legumes have so many different qualities that are amazing that they shouldn’t be passed up on. In terms of helping with your cholesterol, there are some benefits that your greens can give you that few foods can. The soluble fiber in fruits and legumes, as well as oatmeal, form gelatinous substances in the intestine and bind with cholesterol so that it is removed rather than absorbed. Eating just 15 grams of soluble fiber a day can reduce your LDL cholesterol by 10-15% over time.

Exercise and You Won’t Be Sorry

A regular regimen of exercise is extremely helpful in burning off triglycerides and reducing LDL cholesterol while boosting HDL cholesterol. There is no doubt that cardiovascular exercise as well as weight training reduces inflammation, excess fat, and LDL cholesterol. Truly, any amount of exercise is beneficial but those who do it regularly will see the most benefit. You need to remember though that the heart is also a muscle, and while it may seem strange, a whey protein shake after a jog is just what it needs to build itself stronger than ever before.

Get Acquainted with the Good Fats, Throw Out the Bad

A supplement with plant sterols alone is not going to do the trick — essential fatty acids have the most control over your cholesterol levels. Before I say anything, I just wanted everyone to know that I am extremely biased against low/no fat diets. I think they are ridiculous and led to a generation of people coming down with cardiovascular diseases. That’s because fat in your diet is so absolutely necessary that you can’t afford to cut it out. In terms of cholesterol, fat can save your life if you eat the right kinds. So what are they?

Monounsaturated fats are what you want the most of in terms of lowering LDL cholesterol. When eating a salad or some whole wheat pasta, feel free to drizzle a good helping of extra virgin olive oil. Salad dressings based on olive oil are also good. Seriously, olive oil is amazing and shouldn’t be passed up on.

You should also make sure to get a large amount of your essential oils from food sources. Fish have a lot of good fats in them, such as the polyunsaturated omega-3 and omega-6. Avocado is great. Some coconut oil, a medium-chain saturated fat, has been shown to be beneficial as well. You should also eat a decent amount of nuts, as they contain a great amount of oils that are beneficial to the body.

So what are the bad? Any kind of processed or refined oil. That giant, cheap gallon of vegetable oil should be thrown out immediately. There is no better way to raise your triglyceride and LDL cholesterol count than to cook everything in vegetable oil. When oils are heated they undergo a chemical transformation that makes them much less healthy for you. Basically, anything that says processed, hydrogenated, or partially hydrogenated should be thrown out especially if found in packaged food. These are generally trans fats — the biggest culprit in terms of bad cholesterol.

You will also want to trim as much fat off of red meat as possible as, unlike coconut oil which is a medium-chain saturated fat, these are long-chain saturated fats and do have a connection to higher LDL cholesterol. Replace some of your red meat meals with fowl and fish instead.

Some Supplements Do Wonders

There is a reason that bodybuilders and nutritionists are absolutely obsessed with certain supplement products. Their benefits are proven, visible, and effective in everyone.

Flax seeds and flax seed oil are one of nature’s best sources of omega-3 and omega-6 fatty acids. Taken as a supplement or whole, these little guys do wonders for your cholesterol and heart. Cod liver oil is a good alternative, containing these fats along with vitamins A and D naturally.

Like I said, bodybuilders and nutritionists take these because they work. AI put a bit of flaxseed oil in every protein shake I make. While I’m sure the Benecol Smart Chews has had some kind of effect given the plant sterols, I don’t believe that it can have nearly the effect as supplementing with essential fatty acids.

Conclusion

There are many lifestyle changes that you can make in order to boost your cardiovascular health and tackle cholesterol problems. As a natural substance that your body needs, dietary cholesterol itself has very little impact on the cholesterol in your body. When you eat more cholesterol, your body simply makes less. The terms HDL and LDL actually refer to lipoproteins that surround the cholesterol the production of which has much more to do with dietary fat than dietary cholesterol. A good exercise regimen, but most of all a healthy diet full of unprocessed foods and essential unsaturated fatty acids, are essential to raising your HDL and LDL levels, thus preventing the kind of arterial plaque that can lead to so many cardiovascular diseases.

These tips worked for me, and I hope that by following my suggestions you can successfully achieve your goals. Good luck Dr. Helen and everyone else!

Cholesterol Shoots Up

Sunday, July 6th, 2008

Doctors and dieticians stresses on following a special diet chart to the people suffering from cholesterol problem. And if the disease is low-density lipoprotein or LDL, that is, the worst form of cholesterol, the person has to take extra care of his health and diet. A proper diet to lower LDL cholesterol must include food that contain lots of soluble fibre, polyunsaturated fatty acids, Omega-3 fatty acids, sterols or stanols, and soy protein.

The soluble fibre mentioned in a proper diet to lower LDL cholesterol is found in high percentage in oatmeal and oat bran. Foods like kidney beans, Brussels sprouts, pears, apples, barley, psyllium and prunes are also very rich in soluble fibres. These foods reduce the absorption of intestinal cholesterol by helping the body to excrete the dietary cholesterol and excess bile.

A proper diet to lower LDL cholesterol must have five to ten grams of fibre per day to lower the cholesterol by five percent. A person suffering from high cholesterol must consume one-and-a-half cups of cooked oatmeal that contains 4.5 grams of soluble fibre. Besides fibre, polyunsaturated fatty acids help to reduce blood cholesterol. These fatty acids, mostly found in walnuts and almonds, keep the blood vessels healthy, well oxygenated and elastic.

A proper diet to lower LDL cholesterol must include one-third cup of walnuts or almonds every day. This counts to about 240 calories or 20 per cent of the total calorie intake in a day. If consumed at a regular basis, these nuts help to lower cholesterol within one month.

In a proper diet to lower LDL cholesterol, it is very important to have omega-3 fatty acids that are mostly found in fish, and whale and seal meat. Apart from these sources, the other omga-3 fatty acids enriched vegetarian edibles are flaxseed, canola oil, walnuts and Soya bean oil. However this element is best found in fishes and fish oil. The highest carriers of these fatty acids are salmon, sardines, albacore tuna, mackerel, and lake trout.

A proper diet to lower LDL cholesterol must include baked or grilled fish that reduces blood clotting and blood pressure due to their ability to reduce triglyceride. Fat, especially trans and saturated ones are a big no-no for a cholesterol patient. Beside a controlled and healthy diet, regular exercises are also important. In case the cholesterol level shoots up, one must take proper medication.

Cholesterol Diet Fat Low Reduce

Friday, July 4th, 2008

Cholesterol is mainly affected by hereditary factors, weight control, smoking and lack of exercise. And although cholesterol is not primarily affected by the foods we eat, in some cases dietary cholesterol does play a part. See our guide below on how to get a handle on your cholesterol by limiting certain foods and eating more of others.

A low-fat, low-cholesterol diet is desired to keep your total fat consumption–saturated, polyunsaturated and monounsaturated–to fewer than 30 percent of your daily intake of calories. Remember to keep your cholesterol intake to fewer than 300 milligrams per day. Saturated fats contained in butter, whole milk, hydrogenated oils, chocolate shortening, etc. should comprise no more than one third of your total fat consumption. To reduce your total fat and cholesterol intake, limit your consumption of meats such as beef, pork, liver and tongue (always trim away excess fat). In addition, avoid cheese, fried foods, nuts and cream, and try to curb your intake of eggs to no more than four per week. Try to eat meatless meals several times a week, use skim milk and include fish in your diet. Eat a wide variety of vegetables, pasta, grains and fruit. Another good tip is to look at the package label of the foods you buy, and restrict your choices to foods containing 3 grams of fat or less per serving.

There is evidence that water-soluble fibers can aid in lowering cholesterol; these foods include the fiber in oat or corn bran, beans and legumes, pectin found in apples and other fruits, and guar that is used as a thickener. Although highly touted by the media and health food stores, the phospholipid Lecithin has not been confirmed as a reducer of blood cholesterol levels.

If you are overweight, trying to lose weight and including aerobic exercise in your routine can help raise those desirable high density lipoproteins levels. Diet and exercise alone can decrease cholesterol levels by up to 15 percent.

Guidelines for lowering your high blood cholesterol with dietary therapies.
* Eat less than 30% of your total daily calories from fat.
* Eat less than 300 mg of cholesterol each day.
* Eat 50-60% of your daily calories from carbohydrates.
* Adjust your caloric intake to achieve or maintain a desirable weight.

Foods to limit:

* Fat. Cutting back on fried foods, puddings, biscuits, crisps, pies and chips can give you a double benefit: lower cholesterol and lower body weight. Instead, choose reduced fat products such as low-fat soured cream and cream cheese, fat-free yoghurt, skimmed milk and granola.
* Sweets or puddings labelled ‘low-fat’. A low-fat brownie is still a brownie, and it still has loads of calories and fat. These types of reduced-fat foods shouldn’t be part of your daily diet.
* Red meat. You don’t have to cut meat out of your diet, just reduce your portion sizes to about three ounces, or the size of your palm. More than that is over the top in calories, fat and cholesterol.
* Some dairy products. Watch out for your intake of foods high in cholesterol like cheese, sour cream and butter.
* Trans fatty acids.You won’t always find these trans fats listed on food labels, but they are mostly found in foods containing hydrogenated oils, meaning they start as liquid and are chemically changed to solids at room temperature. The hydrogenation process is used in making stick margarine and solid vegetable shortening, and hydrogenated fats are used in commercial baked goods such as puddings, biscuits and other snacks. Look for the word ‘hydrogenated’ on the label and try to limit these foods.

Lipitor Removes Vitamin

Tuesday, July 1st, 2008

Question: I’m 58, split firewood with a mallet, ride a bike, walk, and carry my bag while playing golf. I take the cholesterol-lowering drug Lipitor along with vitamin E, vitamin C, beta-carotene and an aspirin every day. The problem is that my good cholesterol (HDL) is low and my bad cholesterol (LDL) is high. Should I:

1. Keep taking Lipitor and forget vitamin E?
2. Forget Lipitor and take vitamin E?
3. Take Lipitor and forget all the others?
4. Increase the amount of chocolate I eat and feel happy?

Answer: I like your humorous outlook (and active lifestyle), but go a little easy on the chocolate portion of option number 4. As for your multiple choice quiz, I’d add the following option and check it: 5. None of the above (explanation follows).

Your main concern seems to be whether your vitamin E supplement might interfere with the effect of Lipitor. I’ve received similar questions since the media reported that vitamin E might impair the expected ability of cholesterol-controlling drugs to raise levels of HDL cholesterol (the good kind). Actually, the clinical study in question implicated a group of antioxidants, which included vitamin E. The effect was modest, and there was no way to single out the role of vitamin E.

Vitamin E supplements show promise in Alzheimer’s disease, cancer, arthritis and a number of other conditions, so it seems unwarranted to give up your vitamin E unless your physician advises otherwise.

One thing I might question is your use of beta-carotene supplementation, which research suggests may actually increase the risk of heart disease (in smokers) and lung cancer (in smokers and asbestos workers). Since beta-carotene needs are easily met by eating fruits and vegetables, it seems best to get it this way. The nutritional doses present in typical multivitamin supplements should be safe.

A diet low in saturated fats and cholesterol will lower LDL cholesterol (the bad kind). Adding soluble fiber (e.g., barley oats, soy, psyllium) and plant stanol/sterol-containing margarines (e.g., Benecol, Take Control) enhances this effect.

Typically, you should keep your LDL cholesterol below 130 if you’re at moderate risk for cardiovascular complications, or below 100 if you already have heart disease or diabetes. If dietary changes aren’t enough, your physician may adjust the dose of your Lipitor or add a second cholesterol-lowering agent.

You want as much HDL cholesterol as possible because it helps the body round up and remove rampant cholesterol.

The first step in boosting HDL cholesterol levels is to increase physical activity and lose weight (if overweight).

A number of other factors can push down HDL cholesterol, including high triglycerides, smoking, very high carbohydrate intake (this also raises triglycerides), drugs (e.g., anabolic steroids, beta-blockers, progestins, loop diuretics, phenothiazines) and medical conditions (e.g., hyperthyroidism, diabetes, high blood pressure, cholestasis, nephrotic syndrome, chronic renal failure).

Lipitor has only a modest effect on HDL cholesterol, so if your levels stubbornly remain low (below 40), your physician might consider adding a drug that increases HDL cholesterol, such as niacin or a fibrate (e.g., gemfibrozil, fenofibrate).

How to Lower Your Cholesterol?

Cholesterol Lowering Drugs and Cholesterol Lowering Diet

Whatever the reasons may be for your high blood cholesterol level - diet, heredity, or both - the treatment your doctor will prescribe first is a diet. If your blood cholesterol level has not decreased sufficiently after carefully following the diet for 6 months, your doctor may consider adding cholesterol-lowering medication to your dietary treatment. Remember, diet is a very essential step in the treatment of high blood cholesterol.

Cholesterol-lowering medications are more effective when combined with diet. Thus they are meant to supplement, not replace, a low-saturated fat, low-cholesterol diet.

Summary of Diet Guidelines for Lowering High Blood Cholesterol Levels

* Eat less high-fat food (especially those high in saturated fat)
* Replace part of the saturated fat in your diet with unsaturated fat
* Eat less high-cholesterol food
* Choose foods high in complex carbohydrates (starch and fiber)
* Reduce your weight, if you are overweight

Eat Less High-fat Food

Dietary Fat

There are two major types of dietary fat - saturated and unsaturated. Unsaturated fats are further classified as either polyunsaturated or monounsaturated fats. Together, saturated and unsaturated fats equal total fat. All foods containing fat contain a mixture of these fats.

Reduce Total Fat Intake

One of the goals in your blood cholesterol-lowering diet is to eat less total fat, because this is an effective way to eat less saturated fat. Because fat is the richest source of calories, this will also help reduce the number of calories you eat every day. If you are overweight, weight loss is another important step in lowering blood cholesterol levels (as discussed later in this brochure). If you are not overweight, be sure to replace the fat calories by eating more food high in complex carbohydrates.

Remember: When you decrease the amount of total fat you eat, you are likely to reduce the saturated fat and calories in your diet.

Saturated Fat

Saturated fat raises your blood cholesterol level more than anything else in your diet. The best way to reduce your blood cholesterol level is to reduce the amount of saturated fat you eat.

Animal Fats

Animal products as a group are a major source of saturated fat in the average American diet. Butter, cheese, whole milk, ice cream, and cream all contain high amounts of saturated fat. Saturated fat is also concentrated in the fat that surrounds meat and in the white streaks of fat in the muscle of meat (marbling). Poultry, fish, and shellfish also contain saturated fat, although generally less than meat.

Hydrogenated Fat - Known As Trans Fatty Acids or Trans-Fats

Trans fats are created during the food manufacturing process when cheap vegetable oils undergo a process called “hydrogenation” - they have hydrogen added to them to make them solid and less likely to become rancid. Unfortunately, trans fats are even worse for our heart than saturated fat, as they encourage atherosclerosis (narrowing of the arteries).

Vegetable Fats

A few vegetable fats - coconut oil, cocoa butter (found in chocolate), palm kernel oil, and palm oil - are high in saturated fat. These vegetable fats are found in many commercially baked goods, such as cookies and crackers, and in nondairy substitutes, such as whipped toppings, coffee creamers, cake mixes, and even frozen dinners. They also can be found in some snack foods like chips, candy bars, and buttered popcorn. Because these vegetable fats are not visible in these foods (unlike the fat in meats) it is important for you to read food labels. The label may tell you how much saturated fat a food contains, which will help you choose foods lowest in saturated fats.

Remember: Saturated fats are found primarily in animal products. But a few vegetable fats and many commercially processed foods also contain saturated fat. Read labels carefully. Choose foods wisely.

Substitute Unsaturated Fat for Saturated Fat

Unsaturated fat actually helps to lower cholesterol levels when it is substituted for saturated fat. Therefore, health professionals recommend that, when you do eat fats, unsaturated fats (polyunsaturated and monounsaturated fats) be substituted for part of the saturated fat whenever possible.

Polyunsaturated fats are found primarily in safflower, corn, soybean, cottonseed, sesame, and sunflower oils, which are common cooking oils. Polyunsaturated fats are also contained in most salad dressings. But be cautious. Commercially prepared salad dressings also may be high in saturated fats, and therefore careful inspection of labels is important. The word “hydrogenated” on a label means that some of the polyunsaturated fat has been converted to saturated fat.

Another type of polyunsaturated fat is found in the oils of fish and shellfish (often referred to as fish oils, or omega-3 fatty acids). This type of polyunsaturated fat is found in greatest amounts in such fatty fish as herring, salmon, and mackerel. There is little evidence that omega-3 fatty acids are useful for reducing LDL-cholesterol levels. However, fish is a good food choice for this diet play anyway because it is low in saturated fat. The use of fish oil supplements are not recommended for the treatment of high blood cholesterol because it is not known whether long-term ingestion of omega-3 fatty acids will lead to undesirable side effects.

Olive and canola oil (rapeseed oil) are examples of oils that are high in monounsaturated fats. Like other vegetable oils, these oils are used in cooking as well as in salads. Recently, research has shown that substituting monounsaturated fat, like substituting polyunsaturated fat, for saturated fat reduces blood cholesterol levels.

Remember: Unsaturated fats when substituted for saturated fats help lower blood cholesterol levels.

Eat Less High-Cholesterol Food

Dietary cholesterol is a waxy, fat-like substance found in foods that come from animals. Although it is not the same as saturated fat, dietary cholesterol also can raise your blood cholesterol level. Therefore, it is important to eat less food that is high in cholesterol. While cholesterol is needed for normal body function, your liver makes enough for your body’s needs so that you don’t need to eat any cholesterol at all.

Dietary Cholesterol in Food

Cholesterol is found in eggs, dairy products, meat, poultry, fish, and shellfish. Egg yolks and organ meats (liver, kidney, sweetbread, brain) are particularly rich sources of cholesterol. High-fat dairy products, meat, and poultry all have similar amounts of cholesterol. Fish generally has less cholesterol, but shellfish varies in cholesterol content. Foods of plant origin, like fruits, vegetables, grains, cereals, nuts, and seeds, contain no cholesterol.

Since cholesterol is not a fat, you can find it in both high-fat and low-fat animal foods. In other words, even if a food is low in fat, it may be high in cholesterol. For instance, organ meats, like liver, are low in fat, but are high in cholesterol.

Because many foods such as dairy products and some meats are high in both saturated fat and cholesterol, it is important to limit the amount of these high-fat foods that you eat, choosing lean meats and low-fat dairy products whenever possible.

Remember: Organ meats and egg yolks are high in cholesterol. High-fat dairy products, meat, and poultry have similar amounts of cholesterol. Some fish has less. Foods of plant origin like fruits, vegetables, vegetable oils, grains, cereals, nuts, and seeds contain no cholesterol.

Substitute Low GI Carbohydrates for Saturated Fat

Breads, pasta, rice, cereals, dried peas and beans, fruits, and vegetables are good sources of complex carbohydrates (starch and fiber). Low-GI varieties are excellent substitutes for foods that are high in saturated fat and cholesterol. The type of fiber found in foods such as oat and barley bran, some fruits like apples and oranges, and in some dried beans may even help reduce blood cholesterol levels.

Contrary to popular belief, high-carbohydrate foods (like pasta, rice, potatoes) are lower in calories than foods high in fat. In addition, they are good sources of vitamins and minerals. What adds calories to these foods is the addition of butter, rich sauces, whole milk, or cream, which are high in fat, especially saturated fat. It is important not to add these to the high-carbohydrate foods you are substituting for foods high in fat.

Remember: Foods that are high in complex carbohydrates, if eaten plain, are low in saturated fat and cholesterol as well as being good sources of vitamins, minerals, and fiber.

Maintain a Desirable Weight

People who are overweight frequently have higher blood cholesterol levels than people of desirable weight.

You can reduce your weight by eating fewer calories and by increasing your physical activity on a regular basis. By reducing the amount of fat in your diet, you will be cutting down on the richest source of calories. Substituting foods that are high in complex carbohydrates for high-fat foods will also help you lose weight, because many high-carbohydrate foods contain little fat and thus fewer calories.

Fat Contains Twice the Calories of Carbs and Protein

Fat has more than twice the calories as the same amount of protein or carbohydrate. Protein and carbohydrate both have about 4 calories in each gram, but all fat-saturated, polyunsaturated or monounsaturated fat - has 9 calories in each gram. Thus, foods that are high in fat are high in calories. And all calories count. So, to maintain a desirable weight, it is important to eat no more calories than your body needs.

Remember: To achieve or maintain a desirable weight, your caloric intake must not exceed the number of calories your body burns.

Cholesterol What Is It and Are You At Risk?

Sunday, June 22nd, 2008

Cholesterol is a fatty lipid, steroid and an alcohol found in the body tissues and blood plasma of vertebrates. It is the essential part of the outer membranes of human body cells, and it circulates in the blood.

Cholesterol in the human body comes from two major sources. About three-quarters of the body’s total cholesterol is produced within the body, while only one-quarter comes from cholesterol in food.

Higher concentrations of cholesterol are present in body tissues which have more densely packed membranes - i.e. the liver, spinal cord, brain, atheroma, adrenal glands and reproductive organs.

The liver is the most important site of cholesterol biosynthesis. It is secreted from the liver in the form of an acidic secretion known as ‘bile’.

Diets rich in animal fats, meat, poultry, fish, oils, egg yolks and dairy products are a rich source of dietary cholesterol. Organ meats, such as liver and kidney, are extremely rich in cholesterol content, but foods of plant origin contain no cholesterol.

High cholesterol levels in the bloodstream can influence the pathogenesis of certain conditions. Recent studies have revealed that the abundance of protein complexes called lipoproteins, are responsible for the cholesterol build-up in the blood vessels.

Cholesterol gets attached to these lipoproteins. The high-density lipoprotein (HDL) carries cholesterol out of the bloodstream for excretion, while the low-density lipoprotein (LDL) carries it back into the system for use by various body cells.

LDL cholesterol is called bad cholesterol, because elevated levels of it are associated with an increased risk of coronary heart disease. LDL deposits cholesterol on the artery walls which leads to the formation of a hard, thick substance called cholesterol plaque. Over time, cholesterol plaque causes thickening of the artery walls and narrowing of the arteries, a process called atherosclerosis.

The levels of both HDL cholesterol and LDL cholesterol may also determine risk for heart disease; however current medical opinion is that the ratio of HDL cholesterol to LDL cholesterol is much more important than the level of cholesterol.

Methods to control your cholesterol levels:

Lower your consumption of foods containing saturated fats - fried fast foods, butter, cream, cheese, and fat on meat - to help reduce cholesterol. Add more plant foods to your diet - vegetable oils, nuts, legumes, breads, cereal grains, fruits and vegetables. A low cholesterol diet, combined with regular exercise is the best way to lower cholesterol levels.

Medications can also help lower cholesterol levels. HMG-CoA reductase inhibitors, ‘Statins’, such as lovastatin and atorvastatin (Lipitor) are the most effective and widely used medications to lower LDL cholesterol. Other medications include nicotinic acid, fibrates such as gemfibrozil, resins such as cholestyramine, and ezetimibe. These medications should be taken after consulting the experts.

Saturday, June 21st, 2008

High cholesterol affects about 17% of Americans ages 20 and older, contributing to atherosclerotic heart disease, which is the single leading cause of death and disability in the developed world. This medical dictionary covers the terms used in the report, What to do about High Cholesterol, and includes details on how to lower and watch your cholesterol through tests and diets.

* antioxidant: A substance that inhibits oxidation.

* apolipoproteins: Proteins that combine with cholesterol and triglyceride to form lipoproteins.

* atherosclerosis: Development of cholesterol-rich plaque on the inner walls of arteries, which can eventually obstruct blood flow.

* atherosclerotic plaque: A cholesterol-rich deposit on an artery wall.

* biological variability: Fluctuations that occur naturally over time in the levels of a substance such as cholesterol in a person’s body.

* cholesterol: A fatlike substance that is produced by the liver and found in all food from animal sources; an essential component of body cells and a precursor of bile acids and certain hormones.

* chylomicron: A large, extremely low-density lipoprotein that transports triglyceride from the intestine to fat tissue in the body.

* combined hyperlipidemia: A condition in which LDL and triglyceride levels are very high.

* familial combined hyperlipidemia: An inherited disorder in which the liver overproduces VLDL, causing high levels of cholesterol or triglycerides, or both.

* familial hypercholesterolemia: An inherited disorder in which the liver cannot properly remove LDL particles from the blood, causing a very high cholesterol level.

* fasting lipid profile: A laboratory test to determine the relative levels of HDL, LDL, and total cholesterol in the blood. Also referred to as a lipoprotein analysis, full lipid profile, or cholesterol profile.

* fatty acids:
The primary building blocks of lipids.

* foam cells: Lipid-laden cells, named for their foamy appearance under the microscope, which contribute to the formation of atherosclerotic plaque.

* high-density lipoprotein (HDL): A lipoprotein that protects the arteries by transporting cholesterol from body cells to the liver for elimination.

* hydrogenation: The addition of hydrogen to a compound, particularly to solidify unsaturated oils.

* lipids: Fats, oils, and waxes that serve as building blocks for cells or as energy sources for the body.

* lipoproteins: Protein-covered fat particles that enable cholesterol to move easily through the blood.

* low-density lipoprotein (LDL): A lipoprotein that transports cholesterol from the liver to the rest of the body, which can cause the buildup of plaque in the arteries.

* monounsaturated fats: Fatty acids; abundant in olive, peanut, sesame, and canola oils.

* oxidation: A process in which oxygen combines with a substance, altering its structure and changing or destroying its normal function.

* platelets: Minute, colorless disks in the blood that are instrumental in clotting.

* polyunsaturated fats: Fatty acids that are abundant in soybean, corn, cottonseed, safflower, and sunflower oils.

* saturated fats: Fatty acids that are abundant in red meat, lard, butter, cheese, and some vegetable oils, in which each molecule carries the maximum number of hydrogen atoms.

* trans fats: Fatty acids (such as those found in solid margarine) that have been reshaped by hydrogenation; also called trans fatty acids.

* triglyceride: The primary type of fat in the body and in the diet, formed from three fatty-acid molecules and one glycerol molecule.

* unsaturated fats: Fatty acids in which some of the hydrogen atoms in each molecule have been replaced by double bonds; includes monounsaturated and polyunsaturated fats.

* very-low-density lipoprotein (VLDL): A lipoprotein that transports triglyceride manufactured in the liver to fat tissue in the body; eventually becomes low-density lipoprotein (LDL) after the triglyceride has been removed.

In foods, cholesterol is found in eggs, dairy products, meat, and poultry. Egg yolks and organ meats (liver, kidney, sweetbread, and brain) are high in cholesterol. Fish generally contains less cholesterol than other meats, but some shellfish are high in cholesterol.

Foods of plant origin (vegetables, fruits, grains, cereals, nuts, and seeds) contain no cholesterol.

Fat content is not a good measure of cholesterol content. For example, liver and other organ meats are low in fat, but very high in cholesterol.

Therapeutic Lifestyle Changes (TLC) is a set of things you can do to help lower your LDL cholesterol. The main parts of TLC are:

* The TLC Diet. This is a low-saturated-fat, low-cholesterol eating plan that calls for less than 7% of calories from saturated fat and less than 200 mg of dietary cholesterol per day. The TLC diet recommends only enough calories to maintain a desirable weight and avoid weight gain. If your LDL is not lowered enough by reducing your saturated fat and cholesterol intakes, the amount of soluble fiber in your diet can be increased. Certain food products that contain plant stanols or plant sterols (for example, cholesterol-lowering margarines) can also be added to the TLC diet to boost its LDL-lowering power.
* Weight Management. Losing weight if you are overweight can help lower LDL and is especially important for those with a cluster of risk factors that includes high triglyceride and/or low HDL levels and being overweight with a large waist measurement (more than 40 inches for men and more than 35 inches for women).
* Physical Activity. Regular physical activity (30 minutes on most, if not all, days) is recommended for everyone. It can help raise HDL and lower LDL and is especially important for those with high triglyceride and/or low HDL levels who are overweight with a large waist measurement.

Foods low in saturated fat include fat-free or 1percent dairy products, lean meats, fish, skinless poultry, whole grain foods, and fruits and vegetables. Look for soft margarines (liquid or tub varieties) that are low in saturated fat and contain little or no trans fat (another type of dietary fat that can raise your cholesterol level). Limit foods high in cholesterol such as liver and other organ meats, egg yolks, and full-fat dairy products.

Good sources of soluble fiber include oats, certain fruits (such as oranges and pears) and vegetables (such as brussels sprouts and carrots), and dried peas and beans.
