For your heart’s sake, it’s important to strike a healthy balance. Test your knowledge about preventing, detecting and treating high blood cholesterol.
1. Which of these fats are made in your liver?
A. LDL (bad) cholesterol
B. HDL (good) cholesterol
C. Triglycerides
D. All of the above
2. Lowering high LDL (bad) cholesterol levels has all of the following effects except:
A. Slows down or stops fatty plaque buildup in your arteries
B. Increases your chance of having a plaque rupture
C. Reduces your heart attack risk
D. Decreases your chance of dying from heart disease
3. Adults should have their cholesterol levels checked every 10 years. True or false?
4. What are the benefits of exercise that help improve your cholesterol?
A. Trims excess pounds
B. Lowers HDL (good) cholesterol

D. Raises triglycerides
5. Saturated fat can raise your cholesterol level more than anything else in your diet. True or False?
6. Which of these do you NOT need if you take medicine to lower your cholesterol?
A. Regular exercise
B. Diet high in carbohydrates
C. Diet low in saturated fat
D. Weight control
7. If you’ve had a heart attack, lowering your LDL (bad) cholesterol can increase your risk of having another heart attack. True or false?
Answers:
1. D. Your liver makes all the major blood fats. Excess amounts of LDL (bad) cholesterol are deposited in artery walls. In contrast, the job of HDL (good) cholesterol is to remove cholesterol from artery walls. Your total blood cholesterol and ratio of good to bad cholesterol can have a large impact on your risk for heart disease. Excess amounts of triglycerides may also increase heart risk.
2. B. Studies have shown that lowering LDL (bad) cholesterol can prevent heart attacks and reduce deaths from heart disease in both men and women. It can slow, stop or even reverse the buildup of plaque. It can also lower the cholesterol content in some plaques. This makes the plaques cause a heart attack.
3. False. Starting at age 20, men and women should have their cholesterol checked at least every five years. If your cholesterol level is high, you may need to have it checked more often. Talk to your doctor to find out what’s right for you.
4. A, C. Regular activity can help raise HDL (good) cholesterol and lower LDL (bad) cholesterol and triglycerides. It can also help you make improvements in two factors known to bump up cholesterol levels — obesity and increased abdominal girth. A waist of 40 or more inches in men, or 35 or more inches in women, needs to be trimmed.
5. True. The biggest sources of saturated fat are egg yolks, meat and full-fat dairy products such as milk, butter, cream and cheese. Trans fatty acids in hydrogenated vegetable oils can also increase your cholesterol levels.
6. B. You will continue to need exercise, weight control and a cholesterol-lowering diet even if you take medications.
7. False. Lowering LDL (bad) cholesterol levels reduces your risk of another heart attack.

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.

Basically there are two kinds of cholesterol. It’s often talked about, but there still seems to be confusion as to the good and the bad cholesterol.
The bad cholesterol or the LDL (low density lipoprotein) is the kind that is often found in saturated fats and trans fatty acids. These are taken into the body mainly through foods that are pre-packed and prepared such as potato chips, some canned foods, etc.
LDL cholesterol sticks to the walls of the arteries. High levels of LDL can form plaque on the arterial walls that may eventually cause clogging in the blood passageway. This slows down the blood flow, which in turn makes it hard for the heart to pump. This scenario describes the initial stages of hypertension and coronary heart problems.
The good cholesterol HDL (high density lipoprotein) monounsaturated and polyunsaturated fats, these on the other hand lower the levels of LDL by helping to transport the LDL to the liver where it is excreted, lowering the risk for disease. HDL cholesterol can be found in fish as well as nuts.

It’s common knowledge that people have to eat in order to live and have the energy to do the things people do, but what’s easy to forget is - it’s what we eat that makes a lot of difference to our quality of life and whether or not we put ourselves at risk - knowingly or unknowingly.
While some are able to make three or four trips to the buffet table, others are full and satisfied after one round. Those who love to eat red meat and other dishes that are fatty or oily run the risk of contracting a serious condition, which could be life threatening due to the amount of bad cholesterol being taken into the body.
Although cholesterol is one of the main culprits that increases high blood pressure, although not all cholesterol that we take in is essentially bad. In fact, small amounts of cholesterol is being used by the body in the production of bile salts and in the transformation of Vitamin D. Cholesterol also plays a role in balancing hormones, especially in women.

Cholesterol is a problem that millions are facing every day of every year. Learning about cholesterol is the first step to understanding how you are going to handle this problem. High cholesterol does not mean that you are going to die, as long as you take the steps needed to get your cholesterol under control. Understanding and controlling your cholesterol is needed so you can back to focusing on the other things in life that are more important. If you know that there is high cholesterol in your family history we do suggest that you consult with your family doctor while you are concerned about this problem. In learning about cholesterol, you will also need to learn about your body and any other potential health problems you may face.
Cholesterol is something that you really can’t see. You are not going to know you have high cholesterol until you have a blood test done by your family doctor. What you should know about cholesterol is that it is not a poison in your blood, but something that actually does exist in every person as your body does produce cholesterol daily for your body to sustain living. Cholesterol levels in your blood are going to be higher when you eat foods that contain additional fats and cholesterol, but if you are overweight and you are not exercising your body could be producing more than enough cholesterol adding to your high levels.
Cholesterol is going to be higher when you have high stress levels at your home or at your job. Your cholesterol levels may be higher if you are overweight and you are not exercising. Cholesterol is not going to create problems with your heart, but if you add the being overweight and the not exercising to the equation you are at a much higher risk for suffering from heart problems.
The medical problems you face in life are going to be a mixture of what your body needs, and what you provide your body with. The more you exercise, and the more you watch your weight the better you are going to be health wise in the future. If you watch your fat in take and your additional cholesterol intake you are going to be that much further ahead in your healthy life than the person who is not.

There are a lot of confusing terms being thrown around when it comes to cholesterol. Dietary cholesterol is one of those terms. You might think that all dietary cholesterol is bad, but in fact dietary cholesterol does not raise blood cholesterol as much as you might think. The two bad guys here are trans fatty acids and saturated fats.
So when you think about cholesterol problems what you want to do is reduce your levels of bad cholesterol. The best way to do this is through dietary changes. Besides cutting down on foods with bad cholesterol such as meat, dairy, eggs and seafood, you can also eat other foods that will reduce LDL levels.
Trans fatty acids are found in a lot of packaged food. Microwave popcorn, hard stick margarine and some French fries from certain fast food chains are all culprits. By eliminating these foods or finding better substitutes you can cut down your consumption of trans fatty acids that will all contribute to the level of bad cholesterol in your system.
Increasing Good Fats
You can increase the amount of good cholesterol in your body while reducing the bad cholesterol. This is because the presence of good cholesterol in your body means that excess cholesterol will be taken back to the liver to be excreted out of your body. This means you want plenty of good cholesterol as high levels of good cholesterol means a reduced risk of heart disease.
Lifestyle changes such as eating foods rich in soluble fiber, polyunsaturated fats and monounsaturated fats will help increase good cholesterol levels. Increasing the amount of physical activity you do every day will help to lower your cholesterol levels. Limiting alcohol intake — no more than one glass a day for women and two for men — is also a good idea. Taken together, making many small changes in your diet and exercise habits can add up to big changes in your cholesterol level. Why not get started today?

Cholesterol gets so much bad press that it is hard to believe that your body actually needs it. There are two kinds of cholesterol in your body, good cholesterol which is commonly known as HDL cholesterol, and bad cholesterol or the more common name, LDL cholesterol. Cholesterol in your body is necessary to make hormones, vitamin D and bile salts and so is a necessary part of your normal body’s functioning.
The bad cholesterol on the other hand can cause you lots of problems. The main worry with LDL cholesterol is that it will dump cholesterol onto artery walls that will create plaque. The plaque in turn will narrow and block the arteries. This may cause blood flow to be blocked, which is bad news for your heart.

Thanks to powerful cholesterol-lowering statin drugs, driving down low-density lipoprotein (LDL), or “bad” cholesterol, has been the primary approach to improving cholesterol levels. But there’s more to the story of cholesterol and cardiovascular risk than LDL alone. Another key player is high-density lipoprotein (HDL), the “good” cholesterol. Higher levels of HDL are associated with lower cardiovascular risk.
The good news about this good cholesterol is that simple lifestyle changes can help boost HDL, reports the June 2008 issue of Harvard Women’s Health Watch.
HDL removes LDL from artery walls and ferries it to the liver for processing or removal. HDL also fights potentially dangerous inflammation and clot formation.
According to a recent review of research on HDL, there’s some evidence that increasing HDL can reduce the risk of heart attack and stroke—even without changes in LDL.
Harvard Women’s Health Watch suggests several things people can do to nudge up HDL levels. Most of these strategies also improve health in other ways.
1. Get aerobic exercise. Moderate to vigorous aerobic exercise can boost HDL by 5% to 10%. Aim for five 30-minute sessions per week.
2. Lose weight if you need to. If you’re overweight or obese, you can boost your HDL level by about 1 mg/dL for every seven pounds lost, although any amount of weight loss will help.
3. If you smoke, quit. HDL levels rise by as much as 15% to 20% after you quit.
4. Eat a healthy diet. Avoid trans fats, which increase bad cholesterol and decrease good cholesterol. Avoid highly refined carbohydrates, such as white-flour products.
5. Consider medications. Niacin, available over the counter, is the most effective
HDL-raising medication available. Niacin can be strong medicine—work with your clinician if you want to try it.

High cholesterol tends to cause the narrowing and hardening of the arteries, which in turn can lead to heart disease or stroke. What does blood cholesterol level depend on? Many people would say it depends on the kind of food we eat but this is not the whole truth when it comes to high cholesterol. High cholesterol can also be caused in part to how cholesterol is made in your liver.
There are two kinds of cholesterol - the good HDL cholesterol, and the bad LDL cholesterol. HDLs are transporters that carry excess cholesterol to the liver where it can be broken down. LDLs cause the build-up of cholesterol in the arteries leading to high blood pressure and risk of heart attack.
Vitamin C has been found to be a very effective treatment for high cholesterol. Pectin from fruit and vegetables seems to help in fighting high cholesterol by flushing out the excess from the system. Two or three carrots a day is said to be beneficial in lowering high cholesterol. Strawberries, apples, spinach, potatoes and tomatoes are also useful in the treatment of high cholesterol. Vitamin E prevents the oxidation of cholesterol and can therefore prevent hardening of the arteries.
Garlic, turmeric and cinnamon are also very beneficial natural treatments of high cholesterol. Ask your doctor which foods will work best for you.
