What is a vegetarian diet?
Vegetarian Diet Care Guide
- Vegetarian Diet
- En Espanol
A vegetarian (vej-e-TAR-e-an) diet has no meat, fish, seafood, or poultry (such as chicken or turkey). Vegetarians eat mostly grains, vegetables, fruits, dried beans, nuts, and seeds (plant foods). A vegetarian diet is often low in fat. It is lower in fat if low-fat milk products are used, and if it does not have too many nuts and seeds. Vegetarian diets are also high in fiber. Fiber is the part of fruits, vegetables, and grains not broken down by your body. Vegetarian diets may help you control your weight and may prevent some cancers. This diet may also help to lower the cholesterol (ko-LES-ter-ol) in your blood. There are four types of vegetarian diets:
- Lacto-ovo-vegetarian: This diet includes dairy products, eggs, and plant foods.
- Lacto-vegetarian: This diet includes dairy products and plant foods.
- Ovo-vegetarian: This diet includes eggs and plant foods.
- Vegan (VEE-gun): This diet includes only plant foods.
What can I do to make a vegetarian diet part of my lifestyle?
- Changing what you eat and drink may be hard at first. Think of these changes as "lifestyle" changes, not just "diet" changes. You may need to make these changes part of your daily routine. Following a vegetarian diet may help you feel better.
- Choose a variety of different foods allowed on this diet so that you do not get tired of having the same items every day.
- Carry a list of foods allowed on this diet with you to remind you about the diet when you are away from home.
- Many foods suggested for this diet are "fortified" (FOR-ti-fide). If a food is fortified, it has had nutrients added that it does not have naturally. For example, vitamin D fortified milk has vitamin D added to it before it is ready to be sold at a store.
- Ask your caregiver, a dietician (di-uh-TISH-in), or a nutritionist (noo-TRI-shun-ist) any questions you may have about your diet plan. A dietician or nutritionist works with you to find the right diet plan for you. Dieticians and nutritionists can also help to make your new diet a regular part of your life.
- One cup (eight ounces) of food is the size of a large handful.
- One-half cup (four ounces) of food is about half of a large handful.
- One tablespoon (Tbsp) is about the size of the tip of your thumb (from the last crease).
- One teaspoon (tsp) is about the size of the tip of your little finger (from the last crease).
- Two tablespoons is about the size of a large walnut.
- One and one-half cups (12 ounces) of liquid is the size of a soda-pop can.
- A serving size refers to the size of food after it is cooked. Three ounces of cooked meat is about the size of a deck of cards.
- A serving of vegetables is one-half cup (one-half of a handful) cooked or one cup (one full handful) of raw vegetables.
What other diet guidelines should I follow?
It may be difficult to get enough of some vitamins and minerals while on a vegetarian or vegan diet. Diet supplements (pills or liquids bought at a grocery or drug store) may be needed. Adding servings of the following to your diet may also help:
- Vitamin B-12: Dairy products and eggs have vitamin B-12. If you follow a vegan diet, you may need supplements or foods with added B-12. Some foods high in B-12 are fortified ready-to-eat breakfast cereals, and fortified soy milk. Vegetarian meat substitutes, such as burgers or hotdogs made with soy may also have vitamin B-12.
- Calcium: If you do not include dairy products in your diet, you need to be sure to get enough calcium from other foods. Foods high in calcium include broccoli, tofu, soybeans, collard greens, turnip greens, and calcium-fortified juice.
- Vitamin D: Vitamin D fortified cow's milk or soy milk can help you get enough vitamin D. Being in the sun for five to 15 minutes every day can also give your body enough vitamin D. When you are in the sun, be sure your hands, arms, and face are exposed to sunlight.
- Zinc: Foods that are high in zinc include almonds, bran flakes, wheat germ, and chickpeas.
- Iron: Foods that are high in iron include bran flakes, sea vegetables, lentils, legumes (beans), and oatmeal.
- Omega-3 fatty acids: Linolenic acid may help increase the amount of omega-3 fatty acids in the body. Foods that are high in linolenic acid include flax seed, linseed oil, and walnuts.

- You may not receive enough nutrients on a vegetarian diet. A dietician can tell you if your diet is too low in vitamins and minerals. She will also tell you what to do to correct your diet if it does not have enough vitamins and minerals. Some nutrients you may not get enough of include vitamin B-12, iron, calcium and vitamin D, zinc, and omega-3 fatty acids. Talk to a dietician if you do not eat eggs and milk, especially if you are pregnant or breast feeding. When you are pregnant or breast feeding, your body needs more nutrients to support both you and your baby.
- Talk to a dietician if you have children less than five years old who eat a vegetarian diet. Children younger than five are rapidly growing and developing in all areas. Because of this, they may need more and different nutrients than this diet can give them. Talk with your caregiver or dietician if you are losing too much weight on a vegetarian diet.
Call caregivers if:
- You have questions about the serving sizes in this vegetarian diet.
- You have questions about how to prepare or cook foods on this list.
- You have questions about how or where to buy foods on this list.
- You have questions or concerns about this food list, your illness, or medicine.
