trans fat Remember, trans fat is not natural food, its food processed by food companies to expand shelf life Fats have carbon atoms with free valences which means oxygen atoms can fill the valences or open ends available for attachment with the carbon atom This is a good thing at least short term because you can digest them, have the oxygen bond with the carbon during digestion which creates energy for your body But because its a good thing bacteria want to eat the food before you do. Thats why if the food is not fresh or refrigerated, the food will spoil. Thats because the bacteria got to the food before you did Food manufacturers who do not want to incur the expense of food going bad because it sits on the shelf too long try to save money at the expense of your health by "hydrogenating "the fats in their products They chemically place hydrogen atoms at the ends of the carbon atoms to fill the vacancy so to speak so no oxygen can bond This means the food is so bad, the bacteria will leave it alone. It also means the food has no value to you as a human being. This is the process that creates "trans fat" and it will clog your arteries/ Likewise avoid food products that say "partially hydrogenated" Same idea, bad for your arteries So the first thing you should avoid are trans fat Secondly, avoid whole milk. The fat found in regular milk which is not skim milk is worst than the fat found in red meat I eat dairy products such as nonfat milk and whey. After you take the bad fat out of milk, its an excellent food, but the fat in whole milk will really clog your arteries. Don't be deceived by 2% milk. It means 2% by volume which means the other 98% is mostly water. But calorie wise, 2% milk is about 40% bad fat, so stay away from 2% milk. Its not as bad as regular whole milk, but it is still pretty bad for your arteries
