Walnuts Found to Protect Against Heart Disease

Tuesday, November 4th, 2008

Walnuts are believed to have originated in Persia or France where petrified shells of roasted walnuts have been discovered dating back 8,000 years from the Neolithic period.

Walnuts (Juglans) were considered food for the gods in ancient Rome and named Juglans regia (Jupiter’s royal acorn ) in honor of Jupiter. Juglans is derived from Jovis glans, meaning Jupiter’s acorn, and regia meaning royal.

Walnuts should not be shelled until ready to use, and once shelled can be refrigerated in a tightly sealed container for up to one year

The United States is the world’s top producer of walnuts, with California providing more than 50% of worldwide walnut supply. China, France, Turkey, Romania, and Iran are other walnut producing countries.

Health Benefits of Walnuts

* Nutrients
Walnuts are an excellent source of antioxidants and the minerals manganese, copper, phosphorus, and magnesium. Walnuts are a very good source of protein, dietary fiber, the amino acid arginine, omega-3 fatty acids and alpha-linolenic acid (ALA). Walnuts are unique because they are rich in n-6 (linoleate) and n-3 (linolenate) polyunsaturated fatty acids.

* Cardiovascular Health
Alpha-linolenic acid (ALA) is an n-3 polyunsaturated fatty acid found mainly in plant sources, especially walnuts. There have been numerous clinical studies that suggest that alpha-linolenic acid (ALA) intake reduces the incidence of coronary heart disease. Alpha-linolenic acid (ALA) in walnuts may reduce cardiovascular risk through a variety of biologic mechanisms, including platelet function, inflammation, endothelial cell function, arterial compliance, and arrhythmia. Walnuts also contain other potentially cardioprotective constituents including phytosterols, tocopherols, squalene and the amino acid arginine.

Walnuts are rich in the antioxidant ellagic acid, and in a preliminary study, it has been suggested that the ellagic acid present in walnuts has a high anti-atherogenic implicating the beneficial effect of a walnut-enriched diet on cardio protection.

* Cholesterol
A diet supplemented with walnuts has been shown to significantly reduce total and LDL cholesterol levels.

* Alzheimer’s Disease
Fibrillar amyloid beta-protein (Abeta) is the principal component of amyloid plaques in the brains of patients with Alzheimer’s disease. Over 90% inhibition of Abeta fibrillization from walnut extract was observed in a laboratory study, suggesting that walnuts may reduce the risk or delay the onset of Alzheimer’s disease by maintaining Abeta in the soluble form.

* Weight Loss
There is some concern amongst dieters about incorporating walnuts into a weight loss program due to the high fat content. A 12-month study of 90 participants has demonstrated that weight gain from daily consumption of walnuts has been shown to be insignificant.

Kick Cholesterol In The Nuts

Tuesday, October 14th, 2008

According to the American Academy of Anti-Aging Medicine (A4M) online newsletter, snacking on pistachio nuts may help lower levels of “bad” LDL cholesterol.

Penn State University researchers studied the effects of three cholesterol-lowering diets, one without pistachios and two with varied levels of pistachios, on 28 adults with borderline-high LDL cholesterol levels.

For two weeks the participants ate the typical American diet and they then spent a month eating a low-fat, pistachio-free diet.

For another month they followed a healthy diet that included a daily serving of pistachio nuts and for the last month ate a healthy diet, including two daily servings of pistachios.

All diets provided the same amount of saturated fat and cholesterol, but different amounts of unsaturated fat delivered by the pistachios.

LDL cholesterol fell by 9% during the month participants ate one serving of the nuts, and 12% in the month in which they ate two daily servings.

The drop in cholesterol levels was not enough to put participants’ LDL cholesterol into the optimal range, but it was enough to get them out of the borderline-high category. To the surprise of the researchers, the low-fat diet had no effect on LDL cholesterol levels.

All The Info On The New Cholesterol Findings

Thursday, October 9th, 2008

Cholesterol, although a fat, is an essential nutrient for the body. It is made in the liver. The liver produces cholesterol in the necessary quantities for health.

Food that helps to lower cholesterol levels

Other foods that can lower the cholesterol levels are fruits and vegetables. This type of food doesn’t contain that much cholesterol so whatever you eat, you won’t be adding to its levels.

Another great thing about fruit and vegetables is the fact that they are great sources of fibres that the body also needs to combat LDL cholesterol. Berries as well as fruit that is citrus and carrots are just some of the fruit you can count on for combating LDL.

Soya is another food that can dramatically reduce the levels of cholesterol in the body. Fibre rich food, soya as well as almonds and plant sterols also reduce cholesterol levels by as much as 20 percent, according to a recent study. Eating oats, olive oil and barley are also great ways to lower LDL.

To lower LDL, it’s important to consciously avoid foods that are deep-fried. If you have to eat fried foods, make sure that the oil that you use is vegetable oil.

Never use butter as this is rich in saturated fats. Instead, use margarine as a substitute. Steam, braise, boil or bake your food these are both tastier and healthier.

It’s not just the food

There are many factors that contribute to the rise in the levels of cholesterol. In addition to one’s eating lifestyle, there is the age, gender, genes, family history and of course the amount of physical activity that’s done. Exercise is certainly very important in keeping LDL cholesterol at bay. Not only that, it strengthens the body’s resistance as well as improves blood circulation.

One reason for the high levels of cholesterol, could be due to the wide variety of fast food being offered these days at the grocery store and in restaurants. But is there one food product that can be called the best to lower cholesterol? Probably not as a well balanced diet comes from all of the food groups.

Lowering cholesterol quick tips

* Instead of drinking full cream milk on cornflakes or whole grain, try using non or low fat milk instead. The taste is almost the same, but is much healthier.
* Instead of ordering a steak change your menu to lean meat instead, but be careful as even lean meat has fat, although not as much and tastes just as good as the big steak.
* The healthiest thing to have either for lunch and/or dinner is food that comes from the ocean. Fish or shellfish is known to contain concentrates of Omega 3, which is very effective in lowering cholesterol.
* Eating a candy bar or a slice of cake is tempting, but they are rich in fat - although there are low fat and cholesterol free chocolate cake recipe. Try nuts or fruits instead, which are rich in fibre as well as contain vitamins and minerals that are lots healthier than the candy or cake.
* In each meal, don’t forget to add fruit where possible. A salad works well or grated carrots as a side dish. There should be a balance whenever eating meat or fish.
* Chicken is not so good if it’s fried, steamed is far better and a healthier way of cooking it - but remember to remove the skin.

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 High Cholesterol

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.

Cholesterol Free Low Fat Diet

Saturday, June 14th, 2008

Cholesterol is a soft, waxy substance found in all parts of the body. Your body makes some cholesterol, and some cholesterol comes from the food you eat.

Your body needs a little bit of cholesterol to work properly. But too much cholesterol can clog your arteries and lead to heart disease. This article focuses on cholesterol and your diet.

Diet - Cholesterol (Alternative Names)

Cholesterol helps the body produce hormones, bile acid, and vitamin D. Cholesterol moves through the bloodstream to be used by all parts of the body.

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.

In general, your risk of developing heart disease or atherosclerosis goes up as your level of blood cholesterol increases.

More than half of the adult population has blood cholesterol levels higher than the desirable range. High cholesterol levels often begin in childhood. Some children may be at higher risk due to a family history of high cholesterol.

To lower high cholesterol levels:

* Limit total fat intake to 25 - 35% of total daily calories. Less than 7% of daily calories should be from saturated fat, no more than 10% should be from polyunsaturated fat, and no more than 20% from monounsaturated fat.
* Eat less than 200 mg of dietary cholesterol per day.
* Get more fiber in your diet.
* Lose weight.
* Increase physical activity.

The recommendations for children’s diets are similar to those of adults. It is very important that children get enough calories to support their growth and activity level, and that the child achieve and maintain a desirable body weight

The following two sample menus provide examples of an average American diet and a low-fat diet.

AVERAGE AMERICAN DIET

* Breakfast
o 1 egg scrambled in 1 teaspoon of butter
o 2 slices of white toast
o 1 teaspoon of butter
o 1/2 cup of apple juice
* Snack
o 1 cake donut
* Lunch
o 1 ham and cheese sandwich (2 ounces of meat, 1 ounce of cheese)
o White bread
o 1 teaspoon of mayonnaise
o 1-ounce bag potato chips
o 12-ounce soft drink
o 2 chocolate chip cookies
* Snack
o 8 wheat thins
* Dinner
o 3 ounces of broiled sirloin
o 1 medium baked potato
o 1 tablespoon of sour cream
o 1 teaspoon of butter
o 1/2 cup of peas, 1/2 teaspoon of butter

Totals: 2,000 Calories, 84 grams fat, 34 grams saturated fat, 425 milligrams cholesterol. The diet is 38% total fat, 15% saturated fat.

LOW FAT DIET

For the same number of calories, a low-fat diet provides 190 mg of cholesterol, compared to 510 mg of cholesterol for an average American diet. Because fat is high in calories, the low-fat diet actually has more food than the typical American diet.

NOTE: The low-fat diet example is too low in fat for small children to promote good growth. In addition, it may be difficult for them to eat such a large volume of food. Children should have a diet that is closer to 30% of calories from fat. Lower-fat diets may be appropriate in some children. Ask your doctor what is best for your child.

Cholesterol Diet Free Plan

Saturday, June 7th, 2008

Getting a free low fat diet plan from me is just the first step. You have to put in the work! Personally, I prefer the term ‘low saturated-fat diet plan’ since the plan I am about to give you is low in saturated fats, and rich in the ‘good fats’.

How can fat be good for you?

That’s exactly what I thought when I started out as a personal trainer. The answer lies in a series of hormones called eicosanoids. These hormones control every major function in the body. They are influenced by the type and amount of fat you eat, and your lifesyle.

A well designed, free, low fat diet plan combined with a healthy lifestyle (exercise, sound sleep, low stress) is the secret to weight loss. The food list below is an extension of the low cholesterol diet food list.

Important components of a low fat diet plan.

Fruits and vegetables - Fiber.

Eat at least 3 to 5 servings of fruits and vegetables each day. Fruits and vegetables are very low in saturated fat and total fat, and have no cholesterol. When shopping, remember to buy fruits and vegetables to eat as snacks, desserts, salads, side dishes, and main dishes.

Add a variety of vegetables to meat stews or casseroles or make a vegetarian (meatless) main dish. Raw vegetables are crucial to the success of my free low fat diet plan. Try carrots, broccoli, cauliflower, lettuce and store in the refrigerator for quick and easy use in cooking or snacking.

Serve fresh fruit for dessert or freeze (banana, berries, melon, grapes) for a delicious frozen treat. Display fresh fruit in a bowl in the kitchen to make fruit easier to grab as a snack.

To keep naturally lowfat vegetables low in fat and saturated fat, season with herbs, spices, lemon juice, vinegar, fat free or lowfat mayonnaise or salad dressing.

Breads, Cereals, Rice, Pasta, and Other Grains.

Breads, cereals, rice, pasta, and other grains, and dry beans and peas are generally high in starch and fiber and low in saturated fat and calories.

They also have no dietary cholesterol, except for some bakery breads and sweet bread products made with high fat, high cholesterol milk, butter and eggs.

Like fruits and vegetables, naturally low fat, low cholesterol breads and other foods in this group are also good choices. You should be eating 6 to 11 servings of foods from this group each day.

Choose whole grain breads and rolls often. They have more fiber than white breads and are an important component of the free low fat diet plan. Buy dry cereals, most are low in fat.

Limit the high fat granola, muesli, and oat bran types that are made with coconut or coconut oil and nuts, which increases the saturated fat content.

Add fat free milk or 1% milk instead of whole or low fat (2% milk) to save saturated fat and cholesterol.

Buy pasta and rice to use as entrees. Hold the high fat sauces (butter, cheese, cream, white). Limit sweet baked goods that are made with lots of saturated fat, mostly from butter, eggs, and whole milk such as croissants, pastries, muffins, biscuits, butter rolls, and doughnuts. These are also high in cholesterol.

Sweets and Snacks.

Some sweets and snacks, like baked goods (cakes and cookies) cheese crackers, and some chips are high in saturated fat and cholesterol.

The following foods are allowed in the free low fat diet plan, but please do not go overboard. fat free or low fat brownies, cakes, cheesecake, cupcakes, and pastries. Frozen lowfat or nonfat yogurt, fruit ices, ice milk, sherbet, and sorbet.

Caution - these treats may be low in fat, most are not low in calories. So indulge occasionally, especially if you are trying to control your weight with a low fat diet.

Low fat snack foods.

Every free low fat diet plan should include foods as snacks.

Soy chips.
Ready-to-eat cereals without added sugar.
Frozen grapes or banana slices; or other fresh fruit.
Low fat or fat free crackers.
No-oil baked tortilla chips.
Popcorn (air popped or “light”).
Pretzels.
Raw vegetables with nonfat or low fat dip.

Eating Your Way to Lower Cholesterol

Wednesday, February 6th, 2008

Although cholesterol drugs are in the news lately, what is getting lost in the discussion is the fact that it’s possible to lower your cholesterol without drugs. It’s just not as easy.

In fact, many doctors think dietary changes are too difficult for most of their patients. While they typically encourage better eating and a diet low in saturated fat, they also prescribe cholesterol-lowering drugs called statins as a faster way to lower bad cholesterol.

But many people can’t tolerate statins and their side effects. Others simply don’t want to take a pill every day or shoulder the cost of a prescription. For those patients, dietary changes may be a better option.

In 2006, The American Journal of Clinical Nutrition reported on a study of 55 patients with high cholesterol who, over the course of a year, started eating a diet rich in soy proteins, fiber and almonds. All those foods may have cholesterol-lowering properties. Twenty-one patients managed to lower their cholesterol by 20 percent or more by the end of the year. The researchers noted that whether the patient was motivated and actually stuck with the diet most of the time was key.

Journalist Tom Burton, a former colleague, wrote about his own efforts to lower cholesterol without drugs for The Wall Street Journal. He found that many doctors don’t really know how to advise patients about dietary changes to lower cholesterol. He found one who did and used him as a nutrition “coach” to help him figure out which changes would be most effective for him.

The problem for Mr. Burton was that he already had a pretty healthful diet. He ran four miles most days and had given up red meat and most cheese. But his bad cholesterol was 169 mg/dL — far above the 100 mg/dL most doctors recommend. Doctors were telling him statin drugs were in his future.

After documenting his eating habits, Mr. Burton was advised by his doctor to cut out a favorite dish — roast chicken with the skin on. He was told that more of his protein should come from fish, beans and nuts. He phased out the chicken as well as shrimp and squid, which are high in dietary cholesterol. He began including steel-cut oatmeal, eggplant, roasted soybeans, whole-wheat pasta and Brussels sprouts in his diet. He also increased his exercise. His cholesterol numbers were slow to move, but eventually they did, dropping 33 percent.

New Questions on Treating Cholesterol

Friday, February 1st, 2008

Correction Appended

For decades, the theory that lowering cholesterol is always beneficial has been a core principle of cardiology. It has been accepted by doctors and used by drug makers to win quick approval for new medicines to reduce cholesterol.

But now some prominent cardiologists say the results of two recent clinical trials have raised serious questions about that theory — and the value of two widely used cholesterol-lowering medicines, Zetia and its sister drug, Vytorin. Other new cholesterol-fighting drugs, including one that Merck hopes to begin selling this year, may also require closer scrutiny, they say.

“The idea that you’re just going to lower LDL and people are going to get better, that’s too simplistic, much too simplistic,” said Dr. Eric J. Topol, a cardiologist and director of the Scripps Translational Science Institute in La Jolla, Calif. LDL, or low-density lipoprotein, is the so-called bad cholesterol, in contrast to high-density lipoprotein, or HDL.

For patients and drug companies, the stakes are enormous. Led by best sellers like Lipitor from Pfizer, cholesterol-lowering medicines, taken by tens of millions of patients daily, are the largest drug category worldwide, with annual sales of $40 billion.

Despite widespread use of the drugs, though, heart disease remains the biggest killer in the United States and other industrialized nations, and many people still have cholesterol levels far higher than doctors recommend.

As a result, drug companies are investing billions of dollars in experimental new cholesterol-lowering medicines that may eventually be used alongside the existing drugs. If the new questions result in slower approvals, it would be yet another handicap for the drug industry.

Because the link between excessive LDL cholesterol and cardiovascular disease has been so widely accepted, the Food and Drug Administration generally has not required drug companies to prove that cholesterol medicines actually reduce heart attacks before approval.

They have not had to conduct so-called outcome or events trials beforehand, which are expensive studies that involve thousands of patients and track whether episodes like heart attacks are reduced.

So far, proof that a drug lowers LDL cholesterol has generally been enough to lead to approval. Only then does the drug’s maker begin an events trial. And until the results of that trial are available, a process that can take several years, doctors and patients must accept the medicine’s benefits largely on faith.

“You’ve got a huge chasm between F.D.A. licensure and a clinical events trial,” said Dr. Allen J. Taylor, the chief of cardiology at Walter Reed Army Medical Center.

Nonetheless, the multistep process has worked well for several cholesterol drugs — including Lipitor and Zocor, which are in a class of drugs known as statins. In those cases, the postapproval trials confirmed that the drugs reduce heart attacks and strokes, adding to confidence about the link between cholesterol and heart disease.

Doctors generally believe that the amount by which cholesterol is lowered, not the method of lowering it, is what matters.

That continues to be the assumption of Dr. Scott M. Grundy, a professor of medicine at the University of Texas Southwestern Medical Center who was the chairman of a panel in 2001 that set national guidelines for cholesterol treatment.

“LDL lowering, however it occurs, delays development of coronary atherosclerosis and reduces risk for heart attack,” Dr. Grundy said this week. In atherosclerosis, plaque builds up in the arteries, eventually leading to blood clots and other problems that cause heart attacks and strokes.

In the last 13 months, however, the failures of two important clinical trials have thrown that hypothesis into question.

First, Pfizer stopped development of its experimental cholesterol drug torcetrapib in December 2006, when a trial involving 15,000 patients showed that the medicine caused heart attacks and strokes. That trial — somewhat unusual in that it was conducted before Pfizer sought F.D.A. approval — also showed that torcetrapib lowered LDL cholesterol while raising HDL, or good cholesterol.

Torcetrapib’s failure, Dr. Taylor said, shows that lowering cholesterol alone does not prove a drug will benefit patients.

Then, on Monday, Merck and Schering-Plough announced that Vytorin, which combines Zetia with Zocor, had failed to reduce the growth of fatty arterial plaque in a trial of 720 patients. In fact, patients taking Vytorin actually had more plaque growth than those who took Zocor alone.

Despite those drawbacks, that trial, called Enhance, also showed that patients on Vytorin had lower LDL levels than those on Zocor alone. For the second time in just over a year, a clinical trial found that LDL reduction did not translate into measurable medical benefits.

The Enhance trial was not an events trial and was not intended to study whether Zetia or Vytorin were effective at reducing heart attacks. But the growth of fatty plaque is closely correlated with heart attacks and strokes.

Without data from events trials for Zetia and Vytorin, no one can be certain if the drugs help or hurt patients. But Merck and Schering did not begin an events trial for the drugs until 2006, nearly four years after the F.D.A. approved Zetia. That trial will not be completed until 2011.

Dr. Robert M. Califf, the vice chancellor for clinical research at Duke University, and a co-lead investigator on the Zetia trial still under way, said companies should have started the trials more quickly. “Outcome trials ought to start when you know you’re going to get on the market,” he said.

On January, the American Heart Association called for the Zetia outcome trial to be completed as quickly as possible.

Merck has asked the F.D.A. to approve its drug Cordaptive, which raises HDL cholesterol and lowers LDL, without waiting for the results of an events trial. Merck has begun an events trial for Cordaptive, but data will not be available until 2013.

Merck has submitted the application for Cordaptive and has said it expects an answer from the F.D.A. before July. Doctors, patients and the drug industry will be waiting to see whether regulators are still willing to accept the theory that lower cholesterol is always a good thing.
