A study looking at the diets of almost 800 middle-aged and elderly people clearly showed that vegetarians were at a much lower risk of metabolic syndrome – a bunch of health problems (such as high blood pressure, bad cholesterol, blood sugar, body weight and waist circumference) increasing the risk of diabetes and cardiovascular disease – than meat-eaters. A plant based diet was therefore recommended for maintaining good health.
