Medical Forum / General / Nutrition / October 2006You are what you eat... or not so?
I always thought that by consuming food high in cholestrol, my cholestrol level would go up. Similarly, by eating food with high fat content my body fat % would increase. However, someone recently challenged that notion on a misc.fitness forum. Apparently, this individual was eating 10 eggs a day (yolk included) but managed to reduce their cholestrol level. He was working out (lifting weights) during that period. I work out 4 times a week (weights + cardio) and am diligent about avoiding food high in cholestrol (e.g., egg yolk). Could someone please help me understand how food consumption is related to the corresponding increase/decrease in choestrol/fat % in ones body and if my diligence in avoiding high cholestrol or fatty foods is unnecessary? I'm a relatively fit guy in my ideal weight range per age/height and would like to keep it so while maintaining a healthy lifestyle. Many thanks... Yes, there are many claims that are little more than myths, and potentially very dangerous. For example, the choelsterol notions were based upon Ancel Keys work, "Seven Countries." He studied only seven countries, but there was no sound scientific basis for choosing these nations. Moreover, we now know that oxidation of cholesterol is the key thing to avoid, and yet the same old advice, which results in higher rates of cancer and lower overall mortality, dominates the "mainstream" dietary recommendations. Keys himself said that cholesterol in the 200-220 range was best for overall mortality. In any case, I have many essays on these kinds of topics on my web site: http://groups.msn.com/TheScientificDebateForum- Nothing is for sale (by me) and there is no registration required to read anything. MSN sponsors the site, and they put advertising on top, but I cannot remove it, nor do I endorse it. > Could someone > please help me understand how food consumption is related to the > corresponding increase/decrease in choestrol/fat % in ones body and if > my diligence in avoiding high cholestrol or fatty foods is unnecessary? As a general rule cholesterol in food doesn't end up as a cholesterol in the blood, so eating more cholesterol doesn't lead to more in the blood in the fasting state (which is when measurements are taken). The cholesterol you eat tends to be made into bile salts by the liver which then go back into the gut to help digest the next fatty meal. Obviously right after a meal containing cholesterol the blood level does go up, but it's not in a form that can clog arteries. The majority of the cholesterol in the blood *between* meals is made fresh by the liver (usually prompted by insulin). It's made from saturated fat amongst other things, which is why there are the low-fat guidelines, but it's really the high insulin that's the problem as that's what causes the synthesis of "blood" cholesterol.

What are the generally prescribed methods (non medicinal) for reducing the insulin level which you suggest contributes to ones cholestrol count? Does exercise help reduce these levels or is it through diet alone that one can regulate it? Thanks again. > > > Could someone > > > please help me understand how food consumption is related to the [quoted text clipped - 25 lines] > > Thanks again. Cut out refined carbs. Cut out sugars. Cut out white flour products. Cut out fake foods like margarine and shortening and refined and manufactured boxed crap. Soy is crap. White floru pasta and bread contains no useful nutrients. Some vegetable oils are so processed that they are technically rancid in the bottle. Eat real food. Real meat and real fresh produce. Beef, pork, chicken with the skin on. Bone broth soups made from scratch. Real carrots, peas, broccoli, lettuce, etc. There is nothing wrong with fresh eggs and real cheese. Animal fats are healthy, we need the essential fatty acids in animal fats. And animal proteins are something that our bodies need. TC > Matt, thanks for breaking this down in terms I could understand.

Much as TC said, reducing the carb-heavy foods and trying not to have carb-only snacks. In the simplest form this means making sure you get a good dose of protein along with any carbs you eat. Protein helps satisfy the appetite centre of the brain and also stops an overshoot in the removal of blood glucose (which leads to hunger) by insulin . > Does exercise help reduce these levels or is it through diet alone that > one can regulate it? Exercising muscles are pretty good at sucking glucose from the blood, which will eventually lead to a drop in insulin. MattLB When we eat something, it is broken down into simple building blocks, fatty acids, glycerin, simple sugars and amino acids. These are absorbed. You can get practically the same nutrition by having a tube put into your stomach and the same amino acids, fatty acids, sugars, etc., found in food just pumped into your stomach. Whether our protein and fat come from eggs, cows, beans, pigs or fish doesn't matter that much. To say we are what we eat is a total myth. I can eat chicken for lunch, breakfast, dinner and two snacks every day, but I will never grow wings. I can eat beef, but I will never get a 4-chambered stomach. I can eat all the plants that I want, but I will never be able to do photosynthesis. The you are what you eat saying is a total myth. Jeff > The you are what you eat saying is a total myth. The first person to say that was John Harvey Kellogg.http://naturalhealthperspective.com/tutorials/john-kellogg.html Dr. Kellogg also wrote: It is NOT what you eat that counts, but what you digest. Kellogg did NOT mean that if you eat carrots, you would become a carrot yourself. He said a lot of things that were misinterpreted by the public. The most famous one resulted in him being accuse of pantheism and excommunicated from the Seventh Day Adventist Church. Dr. Kellogg liked to compare the body to an expensive piece of equipment. He suggested that you should take care of your body, just like you would for an expensive piece of equipment. You are what you eat, referred to eating only high quality healthy foods as a primary means of taking care of your body. |
