A vegetarian diet, rich in plant-based foods such as fruits, vegetables, legumes, and grains, offers numerous health benefits including weight management, diabetes control, and prevention of heart disease and cancer. There are different types of vegetarians: strict vegans, lacto vegetarians, lacto-ovo vegetarians, and flexitarians. A well-planned diet is crucial to avoid deficiencies in nutrients like iron, vitamin D, and B12. Diverse plant foods ensure adequate nutrient intake.
