- QUESTION: Even with all the stuff in newspapers and magazines about blood
- fats and heart attacks, I still can't straighten out the story of these
- substances, particularly cholesterol and triglycerides, in my mind. Can you
- please help me?

- ANSWER: Questions about cholesterol and triglycerides are just about the most
- frequently asked of all the letters addressed to me. It's a fairly
- complicated situation and I'll try to make it as easy to understand as
- possible, but if you don't get it all right this time, fear not, as I am sure
- we will be writing more about it as time goes on.
- Cholesterol and triglycerides are fatty substances in our blood left over
- from the food we eat or are made by our bodies from carbohydrates and fat.
- Both are essential to health. For instance, triglycerides give us energy and
- cholesterol aids digestion. Problems, particularly those involving the heart,
- only occur when we get too much of these substances in our system and can't
- get rid of them.
- If we eat more sugars and starches (carbohydrates) than our bodies can
- use, the excess is turned into fat. And it is this fat from which our bodies
- make triglycerides. Likewise, food that comes from animals, such as meat, egg
- yolks, and dairy products, supplies both triglycerides and cholesterol. Since
- Americans eat large quantities of red meat and dairy products, we ingest large
- quantities of both triglyceride and cholesterol. The fat in these products is
- "saturated," meaning it stays solid at room temperature.
- While the fats found in such things as grains, corn, fish, and sunflower
- seeds tend to mix with our blood, animal fats do not. They float in the
- bloodstream waiting to be picked up and carried out of the body by "helpers"
- called proteins. The trouble is some proteins do a better job of getting rid
- of the fat than others. And the more solid (saturated) fat there is in the
- body, the harder it is for the proteins to do their job.
- The three types of fat-carrying proteins (lipoproteins) in the
- bloodstream are: high-density lipoproteins (HDLs), low-density lipoproteins
- (LDLs), and very low density lipoproteins (VLDLs). HDLs are called fat
- removers because they are hefty (dense) enough to absorb the fat and carry it
- off. LDLs are called fat carriers because they aren't thick enough to capture
- the fat. They just grab on to it and pull it along. As the fat is pulled
- through the system, some of it breaks off and sticks to the walls of the blood
- vessels, causing a buildup called atherosclerosis. This buildup can
- eventually clog up the arteries that feed the heart, leading to chest pain
- (angina) or a heart attack.
- Nobody knows why, but some people are born with the tendency to have high
- LDL levels, which may signal an early death from heart disease. Others (as
- well as vegetarians and athletes) are prone to high HDL, or "good
- cholesterol." While it wouldn't be healthy to avoid eating fat all together,
- experts say it makes sense to limit the amount and choose the unsaturated
- kind. In addition, increased exercise and a nonsmoking lifestyle both promote
- higher levels of protective HDL.
- So you can see the story of cholesterol and triglycerides isn't all bad,
- and a little common sense, a bit of knowledge, and an attitude of moderation
- can do much to limit the bad side of this tale.
