...es. Modified foods include calcium-enhanced orange juice, folate-enriched breads and foods formulated with bioactive ingredients like fish oils, plant sterol esters or lutein. Medical foods include PKU formulas free of phenylalanine. Foods for special dietary uses include gluten-free and lactose-free foods....Resveratrol prevents fat accumulation in livers of 'alcoholic' mice
...ted the activity of AMPK in the livers of mice fed alcohol. They further found that the increased expression of SIRT1 and AMPK led to: Reduction of sterol regulatory element binding protein (SREBP-1) Activation of peroxisome proliferator-activated receptor gamma co-activator alpha (PGC-1α) Eleva...Vitamin D a key player in overall health of several body organs, says UC Riverside biochemist
...thesized in the body in a series of steps. First, sunlight's ultraviolet rays act on a precursor compound in skin. When skin is exposed to sunlight, a sterol present in dermal tissue is converted to vitamin D, which, in turn, is metabolized in the liver and kidneys to form a hormone. It was Norman's laborat...'Healthy' sterols may pose health risk
...ry cholesterol into the body, and as such high vegetable diets and/or plant sterol supplements are often used to alleviate high cholesterol. However, although...hers will need to conduct more studies, such as whether dietary sterols and sterol supplements produce different effects. ...Mapping the genetic locus for triglycerides
...e especially promising candidates: angiopoietin-like 3, which inhibits enzymes that break down fats; the receptor for the appetite hormone leptin; and sterol carrier protein 2, which helps convert cholesterol into bile acids. The researchers also note that another recent study identified a single nucleo...Corazonas Foods and Brandeis University partner to create cholesterol-reducing snacks
...tified with natural (chemically unmodified) plant sterols. Found naturally in fruits, vegetables, whole-grain products and most vegetable oils, plant sterol levels are usually too low to effectively combat LDL cholesterol. The Brandeis technology makes natural plant sterols biologically available in oils ...Lipids get new comprehensive classification system
...e LIPID MAPS classification scheme, lipids are divided into eight primary categories: fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, sterol lipids, prenol lipids, saccharolipids, and polyketides. These categories are based on the functional backbone of the lipid molecule from a chemical st...Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats
...turated fats. The research also showed that when the fats triggered PGC-1beta, the co-activator interacted physically and turned up the function of sterol responsive element binding proteins. These important parts of the mechanism activate many key genes of lipid biosynthesis involving the pathways of ch...
