A research article published in Plos One in2018 looks at results of multiple observational studies focused on one or more cardio-metabolic risk factors in vegans and omnivorous diets. Macro-nutrient intake and cardio-metabolic risk factors were compared by dietary pattern. People on vegan diets and others on omnivorous diets were compared for energy, saturated fats, body mass index, lipoprotein cholesterol, triglycerides, glucose levels, blood pressure. The results support the idea that plant-based diets are likely to lower the risk of cardiovascular disease and diabetes.
