NUTR3000 Study Guide - Quiz Guide: Resveratrol, Red Wine, Natriuretic Peptide
Document Summary
Pectins (fruits) and soluble bres (oats and barley) reduce cholesterol, but not by much. A very high intake of soluble bre is necessary to elicit a small effect on [ldl]. The effect is certainly less than that which occurs in response to changing intakes of saturated fat. High bre diets make the person feel fuller" and can in turn reduce saturated fat intake. Fibre intake should average at least 30-40g a day. Alcohol intake mobilises triglycerides (tgs) (= blood fats). The mediterranean diet that is associated with a relatively low risk of cvd includes red wine. Research has considered whether red wine confers protection against cvd. Red wine provides a chemical called resveratrol (apolyphenol). Resveratrol levels are higher in red wines produced in harsh climates (from red grapes that have had a stressed life). Berrouguietal. (2009;atherosclerosis) have attempted to elucidate the mechanisms through which resveratrol reduces the risk of cvd.
