D-7 Trans Fatty Acids

When eating of excess total trans fatty acids cause insulin resistance and high blood glucose, because different types of fats each has different effects on insulin resistance and capability to control blood glucose levels.

The dietary fats include trans fatty acids, saturated fatty acids, and unsaturated fatty acids.

Figure shows low carbohydrate and high Trans or saturated fatty acids -diets in a long term cause insulin resistance, then increases the risk of diabetes, and mortality.

Trans fatty acids occur naturally in beef, pork, lamb, butter, and milk (1% and 10% of of total fat content). A lot of amount of trans fat in process diets known as hydrogenation - a chemical manufacturing process used to convert unsaturated fatty acids into saturated fatty acids to turn liquids into solids for the purpose for long shelf lives, e.g. margarine.

Trans fats in processed foods,including cakes, pies, cookies, biscuits, breakfast sandwiches, margarines, crackers, microwave popcorn, cream-filled candies, dough-nuts, ready-to-use dough, and both dairy and non-dairy coffee creamers, and partially hydrogenated vegetable oil , less or zero cholesterol) it cause more metabolic damage than cholesterol.

Trans fatty acids wih an increasing list of cardiovascular diseases, including congestive heart disease, stroke, arteriosclerosis, high cholesterol, high blood pressure, even a small amount of trans fatty acids can directly elevate LDL cholesterol, reduce HDL cholesterol, cause vascular inflammation and accelerate the development of arteriosclerotic plaques both in the heart and in peripheral blood vesels, implicated in cognitive decline, Alzheimer's disease, ether due to direct damage to neurons in the brain or indirectly increasing cholesterol levels which associated to Alzheimer's disease.

A lots of evidences have shown that trans fats directly impair the ability of pancreas beta cells to respond to glucose in both animals and cell cultures.

Harvard T. H. Chan, School of Public Health performed an analysis on data from 200,000+ individuals showed that a higher intake of trans fatty acids was associated with a higher risk of type 2 diabetes over 14 year course test.
