Nutritional factors in the prevention and management of coronary artery disease and heart failure.
Nutritional factors such as magnesium, folic acid, vitamins B12 and B6, L-arginine, and polyunsaturated fatty acids (PUFAs) appear to be significantly beneficial for patients with coronary artery disease (CAD), and in the prevention and arresting the progression of HF and cardiac arrhythmias. Additionally, ingestion of adequate amounts of protein and maintaining normal concentrations of plasma albumin seem to be essential for these patients. These nutrients closely interact with the metabolism of L-arginine-nitric oxide (NO) system, essential fatty acids, and eicosanoids such that beneficial products such as NO, prostaglandin E1, prostacyclin, prostaglandin I3, lipoxins, resolvins, and protectins are generated and synthesis of proinflammatory cytokines is suppressed that results in platelet anti-aggregation, vasodilation, angiogenesis, and prevention of CAD, cardiac arrhythmias, and stabilization of HF. This implies that individuals at high risk for CAD, cardiac arrhythmias, and HF and those who have these diseases need to be screened for plasma levels of magnesium, folic acid, vitamins B12 and B6, L-arginine, NO, various PUFAs, lipoxin A4, resolvins, protectins, asymmetrical dimethylarginine (an endogenous inhibitor of NO), albumin, and various eicosanoids and cytokines and correct their abnormalities to restore normal physiology.

Randomized Controlled Trial Comparative Study
Comparative effectiveness of plant-based diets for weight loss: a randomized controlled trial of five different diets.
The aim of this study was to determine the effect of plant-based diets on weight loss. ⋯ Vegan diets may result in greater weight loss than more modest recommendations.

Curcumin is the major polyphenolic constituent of an indigenous herb, Curcuma longa, found to have a wide range of applications right from its kitchen use as a spicy ingredient to therapeutic and medicinal applications in various diseases. Curcumin has been identified to have a plethora of biologic and pharmacologic properties owing to its antioxidant and anti-inflammatory activities. ⋯ This review summarizes various in vitro, in vivo studies done on curcumin and its therapeutic utility in diabetic micro-vascular complications. This review also emphasizes the importance of curcumin in addition to the existing therapeutic modalities in diabetic complications.

The aim of this study was to determine whether ascorbic acid (AsA) deficiency-induced endotoxin influx into portal blood from the gastrointestinal tract contributes to the inflammatory changes in the liver. ⋯ These results suggest that AsA deficiency-induced endotoxin influx into portal blood from the gastrointestinal tract contributes to the inflammatory changes in the liver.
