Plant-based diets were once again found to lower the risk of disease in this umbrella review looking at data from nearly 50 studies published over 23 years. They found that vegetarian and vegan diets are significantly associated with better lipid profile (fats in the blood), glycaemic (blood sugar) control, body weight/BMI, inflammation and a lower risk of heart disease and cancer.

Previous studies have shown that diets low in plant foods and rich in meat, refined grains, sugar and salt are associated with a higher risk of death. Reducing your consumption of animal-based products in favour of plant-based foods could then lower your risk of disease. They conclude that plant-based diets may reduce cardiometabolic risk factors, cardiovascular diseases (such as heart disease and stroke), cancer risk and death.

The authors said: “Our study evaluates the different impacts of animal-free diets for cardiovascular health and cancer risk showing how a vegetarian diet can be beneficial to human health and be one of the effective preventive strategies for the two most impactful chronic diseases on human health in the 21st century.”
