HEALTH: SATURATED FATS, CHOLESTEROL ARE NOT EVIL

Could it be possible that after all of these  years that we were advised to “pass on the butter” in order to promote heart health, we were mistakenly directed?   
For the past 60 years, saturated fat and cholesterol have been wrongfully maligned as the culprits of heart disease, one of the nation’s leading causes of death. As noted in the June 23 Time Magazine cover story, refined carbohydrates, sugar, and processed foods are the real enemy — not the saturated fats found in foods such as butter, lard, or eggs.  
The revelation comes on the heels of Dr. Fred Kummerow’s research on fats. Dr. Kummerow, author of “Cholesterol Is Not the Culprit,” has spent eight decades studying the science of lipids, cholesterol, and heart disease. He was the first researcher to identify which fats actually clog your arteries.  His work shows that it’s not saturated fat that causes heart disease, but rather trans fats are to blame. 
What is a trans fat? According to the American Heart Association, trans fats, also called trans fatty acids, are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. Another name for trans fats is “partially hydrogenated oils.”
Food makers once used artificial trans fats to enhance the flavor, texture and shelf life of processed foods.  These fats can be found in many foods — but especially in fried foods like French fries and doughnuts, and baked goods including pastries, piecrusts, biscuits, pizza dough, cookies, crackers, stick margarines and shortenings. 
Trans fats consumption is considered an emerging health problem because it can raise your Low Density Lipoprotein (LDL) cholesterol levels and lower your High Density Lipoprotein (HDL) cholesterol levels.

Unfortunately, when the cholesterol hypothesis took hold following the issuance of the first Dietary Guidelines for Americans in February 1980, the food industry switched over to low-fat foods. They began replacing healthy saturated fats like butter and lard with harmful trans fats and lots of refined sugar and processed fructose. 
Our ever-rising obesity and heart disease rates illustrate the ramifications of this flawed approach.
We are now beginning to see the rest of the world attempting to catch up with Dr. Kummerow’s research. In November 2013, The U.S. Food and Drug Administration announced its preliminary determination that partially hydrogenated oils, the primary dietary source of artificial trans fat in processed foods, are not “generally recognized as safe” for use in food.  
Several food manufacturers and restaurants have voluntarily taken steps to limit or eliminate trans fat from their products.  Additionally, groundbreaking public health policies, such as the 2007 New York City regulation banning partially hydrogenated vegetable oils and spreads in restaurants, are becoming model public health practices for our nation.
