Eating a Vegetarian Diet
A vegetarian diet is based on plant foods. It includes fruits, vegetables, beans, grains, seeds, and nuts. Some vegetarians also eat dairy foods and eggs. There are three common vegetarian diets:
-
Lacto-ovo vegetarians eat eggs, yogurt, cheese, and other milk products, as well as plant foods.
-
Lacto vegetarians eat dairy and plant foods but not eggs.
-
Vegans eat only plant foods.

Vegetarian basics
A vegetarian diet can be a healthy way to eat for people of all ages. But meals and snacks must be planned to include nonmeat sources of protein, vitamins, and other nutrients. (See the chart below.) Here are some guidelines for healthy meal planning:
-
Eat a wide range of foods. This will help you get all the nutrients you need.
-
Eat a number of plant proteins throughout the day.
-
Plan for enough calories each day. Also make sure that your calories come from foods that are rich in protein, vitamins, and minerals.
-
If you eat dairy foods, choose low-fat or fat-free milk, yogurt, or cheese.
Do you need supplements?
A vegetarian diet can easily supply all the calories, protein, vitamins, and minerals that a person needs. But some people have special needs. This may include children and teens, pregnant and lactating women, women past midlife, older adults, and vegans. If you are in one of these groups, you may need extra calories, protein, calcium, iron, vitamin B-12, vitamin D, or zinc. The lists below can help you choose foods that are good sources of these nutrients. And be sure to ask your healthcare provider about taking vitamin supplements.

Getting started
Change to a vegetarian diet slowly. Start by eating more grains, beans, vegetables, and fruits. Make fish, poultry, or meat a side dish. Then slowly cut them out of your diet. Here are some other tips:
-
Eat 3 or more servings of vegetables a day. Eat them raw or lightly steamed.
-
Eat 2 or more servings of fruit a day. Choose whole fruits with the skin on.
-
Choose a wide range of grains and whole-grain breads and cereals. Eat 6 or more servings of these foods each day.
-
Begin to replace meat by working up to 2 to 3 servings a day of beans, lentils, split peas, tofu, or tempeh.
-
If you eat dairy foods, have 2 to 3 servings a day. Make low-fat or fat-free choices.
For vegans: Add sources of calcium and vitamin B-12, such as fortified nondairy milks and breakfast cereals. Talk with your healthcare provider about vitamin supplements.
