A vegan (say "VEE-gun" or "VAY-gun") diet is a type of vegetarian diet. Besides not eating meat, vegans don't eat food that comes from animals in any way. That includes milk products, eggs, honey, and gelatin (which comes from bones and other animal tissue).
There are many reasons why some people choose a vegan diet.
In general, people who don't eat meat:
The health benefits may be related to a diet of mostly fruits, vegetables, and whole grains.
Protein is made of building blocks called amino acids. The human body can make some of these amino acids. But you must get the nine essential amino acids from food.
Protein isn't just found in meat. If you are looking for alternatives to meat, the following foods are equal to about 1 oz of meat.
You can get more protein in your food by adding high-protein ingredients. For example, you can:
You can also buy protein bars, drinks, and powders. Check the nutrition label for the amount of protein in each serving.
A healthy vegan diet includes mostly whole foods and less-processed foods in each meal. A vegan diet can give you most of the nutrients you need.
As long as you eat a variety of foods, there are only a few things you need to pay special attention to.
Foods that have calcium include certain legumes, certain leafy green vegetables, nuts, seeds, and tofu. Calcium-fortified breakfast cereals, nut milks, and orange juice are also good choices.
Getting enough calcium and vitamin D is important to keep bones strong. Vegans can have nut milks, breakfast cereals, and other foods with added vitamin D.
Getting enough iron isn't a problem if you eat a wide variety of food. Vegan iron sources include cooked dried beans, peas, and lentils; leafy green vegetables; and iron-fortified grain products. Eating foods rich in vitamin C will help your body absorb iron.
Vitamin B12 is found only in foods that come from animal sources. Vegans need to eat foods that are fortified with this vitamin (such as nut milks and breakfast cereals) or take a supplement that contains it.
Vegan sources of zinc include whole-grain breads, beans and lentils, soy foods, and vegetables.
Vegan sources of omega-3 fatty acids include hemp seeds, flaxseeds, pumpkin seeds, walnuts, certain leafy green vegetables, soybean oil, and canola oil.
A well-planned vegetarian or vegan diet can be healthy for children and teens. In fact, it can be a great way to get them into a lifelong habit of healthy eating.
Here are some things to think about at different stages of a child's life.
Supplements may be important.
Children ages 1 to 2 years need extra fat for brain and nerve development.
Vegan and vegetarian diets can contain a lot of fiber. Fiber fills you up without adding a lot of calories. But children have small stomachs. The fiber they eat can fill them up before they get enough calories. Frequent meals and snacks with plenty of whole grains, beans, and nuts will help children get the energy and nutrients they need for healthy growth.
Young children who eat a vegetarian or vegan diet tend to be slightly smaller but still within normal growth ranges. And they tend to catch up to other children in size as they get older.
Teens need plenty of calcium and vitamin D. And iron is especially important for teen girls who are menstruating. If your teen decides to follow a vegetarian or vegan diet:
