Vegetarian diets continue to increase in popularity. Reasons for following a vegetarian diet vary but include health benefits. Following a vegetarian diet may reduce the risk of heart disease, diabetes and some cancers.

But some vegetarian diets may rely too heavily on processed foods with too many calories, and too much sugar, fat and salt. These diets may not include enough fruits, vegetables, whole grains and nutrient-rich foods.

With planning, a vegetarian diet can meet the needs of people of all ages, as well as people who are pregnant or breastfeeding.

The key is to be aware of your nutritional needs so that you plan a diet that meets them.
