CV Nutrition Flashcards
omega 6 examples
linoleic acid- found in seeds, nuts, grapeseed oil
saturated fat impact on health
raise LDL levels, unclear association w/ CVD
MUFA impact on health
do not raise LDL and may improve HDL levels and TGs
MUFA examples
palmitoleic acid, oleic acid- olive oil, canola oil, avocado
omega 6 PUFA impact on health
decrease LDL, total CE, and TGs
-increased conversion to bile acids (to make u for extra CE synth), increase LDL receptors, less conversion of VLDL to LDL, less FA synthase activity
overall advice on omega FA
mixture of omega 3 and 6 from foods
omega 3 impact on health
decrease TGs, increase HDL
-increased lipoprotein lipase activitiy, reverse CE transport
outcome of ORIGIN trial
omega 3 supplement: no difference in CV death, reduced TG levels
trans fat impact
raise LDL and reducing them lowers CVD risk
emphasis of DASH diet
high in K, Mg, Ca, fiber in concordance w/ low sodium diet
overall conclusion of Look AHEAD study of lifestyle interventions in diabetes
improvements in CV risk factors but no reduction in CV events, however less hospitalizations, KD, physical and cognitive fn
dietary cholesterol effect on health
may raise LDL but under debate, mostly from animal products
plant sterols effect
reduce LDL cholesterol
