Plasma lipids and glycaemic indices in Australians following plant-based diets versus a meat-eating diet – Lipids in Health and Disease
Background Vegan and vegetarian dietary patterns are known to beneficially modulate risk factors for cardiovascular disease; however, the current literature does not differentiate between various plant-based diets. This study aimed to examine the association between various plant-based diets and plasma lipids and glycaemic indices compared to a regular meat-eating diet. Methods A cross-sectional study of Australian adults (n = 230) aged 30-75yrs habitually consuming the following were recruited: vegan, lacto-vegetarian, pesco-vegetarian, semi-vegetarian, or regular meat-eater. Multivariable regression analysis was used to adjust for covariates. Results Compared to regular meat-eaters, vegans had significantly lower total cholesterol (-0.77mmol/L,95% CI -1.15, -0.39, P < 0.001), low-density lipoprotein cholesterol (LDL-C, -0.71mmol/L, 95% CI -1.05, -0.38, P < 0.001), non-high-density lipoprotein cholesterol (non-HDL-C, -0.75mmol/L, 95% CI -1.11, -0.39, P < 0.001), total cholesterol/HDL-
