Plant-based diets reduce mortality from heart disease, cancer and all causes, according to a study published in the American Journal of Clinical Nutrition. Researchers compared diet records with mortality rates for 22,421 participants from the Malmo Diet and Cancer cohort. Those with particularly high intakes of fruits, vegetables, legumes and whole grains and reduced intakes of animal products and saturated fats lowered their mortality rates for cancer, heart disease and all causes by 25% when compared with those who did not closely follow a healthy diet.
