"High intake of unsaturated, unhydrogenated fats may be protective against Alzheimer disease, whereas intake of saturated or trans-unsaturated (hydrogenated) fats may increase risk ... These data [...] provide promising evidence that diets high in unsaturated, unhydrogenated fats and low in saturated and trans-unsaturated fats may protect against dementing disease."

"suffice it to say that trans fatty acids are b-a-a-a-d. They raise your total blood cholesterol level and your LDL, or bad cholesterol; lower your HDL, or good cholesterol; and are suspected of contributing to obesity and diabetes. "

"... trans fats, the damaged fats that become, in effect, poisonous, toxic to the cell membranes they are attached to. Studies have shown them to be key factors in heart disease (because among other things they raise LDL - the bad cholesterol - and lower HDL - the good). They also inhibit insulin from binding to the cells, which creates blood sugar problems that lead to diabetes and obesity... "

"More than a decade of research at the University of Maryland, as well as research that was being done at other institutions, showed that consumption of trans fatty acids from partially hydrogenated (a process that adds hydrogen to solidify or harden) vegetable fats and oils had many adverse effects in health areas such as heart disease, cancer, diabetes, immunity, reproduction and lactation, and obesity."
