More green, less red
Studies promote the many health benefits of a vegetarian diet, but you don't need to go full veggie to reap the rewards.
Most men recognize the value of a vegetarian diet, but following one can feel daunting. "Men's diets tend not to change much as they age, and they stick with their favorite foods," says Dr. Qi Sun, an assistant professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. "A change to vegetarianism can feel overwhelming and confusing and thus may not be sustainable."
A solution is to become a "semi-vegetarian": adopt a plant-based diet in which you cut out the red and processed meat and eat healthier animal products like seafood and poultry only occasionally.
