Probably the most frequent questions for teenage vegetarians are about the nutritional adequacy of their food choices. A vegetarian diet can be enjoyed by people of all ages. The key to a healthy vegetarian diet is variety. Just as your parents should be concerned if you only eat hamburgers, they should also worry if you only eat potato chips and salad. A healthy, varied vegetarian diet includes fruits, vegetables, plenty of leafy greens, whole grain products, nuts, seeds and legumes.
Teenage vegetarians have nutritional needs that are the same as any other teenager.
The years between 13 and 19 are times of especially rapid growth and change. Nutritional needs are high during these years. The nutrients you will probably be asked about the most are protein, calcium, iron, and vitamin B12. Only fruits, fats, and alcohol do not provide much protein, and so a diet based only on these foods would have a good chance of being too low in protein. A mixture of plant proteins eaten throughout the day will provide enough essential amino acids.
