Vegetarian diet: How to get the best nutrition

A healthy vegetarian diet consists primarily of plant-based foods, such as fruits, vegetables, whole grains, legumes, nuts and seeds. Because the emphasis is on nonmeat food sources, a vegetarian diet generally contains less fat and cholesterol, and typically includes more fiber.

Vegetarians fall into groups defined by the types of animal-derived foods they eat:

  • Vegans eat only plant-based foods. They don't eat foods from animals, including meat, poultry, fish, milk, eggs and cheese.
  • Lacto-vegetarians consume milk and milk products along with plant-based foods. They omit eggs as well as meat, fish and poultry.
  • Lacto-ovo vegetarians eat eggs, milk and milk products, such as cheese and yogurt, in addition to plant-based foods. They omit red meat, fish and poultry.
  • Flexitarians (semivegetarians) primarily follow a plant-based diet but occasionally eat small amounts of meat, poultry or fish.
To keep your vegetarian diet on track, you may find using a vegetarian food pyramid helpful.
This pyramid outlines various food groups and food choices that, if eaten in the right quantities, form the foundation of a healthy vegetarian diet.

No matter what your age or situation, a well-planned vegetarian diet can meet your nutritional needs. Even children and teenagers can do well on a plant-based diet, as can older people, and pregnant or breast-feeding women. If you're unsure whether a vegetarian diet is right for you, talk to your doctor or a registered dietitian.

Carbohydrate Plus Protein Speeds Recovery

Research shows that combining protein with carbohydrate in the two hours after exercise nearly doubles the insulin response, which results in more stored glycogen. The optimal carbohydrate to protein ratio for this effect is 4:1 (four grams of carbohydrate for every one gram of protein). Eating more protein than that, however, has a negative impact because it slows rehydration and glycogen replenishment.

One study found that athletes who refueled with carbohydrate and protein had 100 percent greater muscle glycogen stores than those who only ate carbohydrate. Insulin was also highest in those who consumed a carbohydrate and protein drink.

Eating After Exercise

It is also important to consume such as fruit or juicewithin 15 minutes post-exercise to help restore glycogen.

Research has shown that eating 100-200 grams of carbohydrate within two hours of endurance exercise is essential to building adequate glycogen stores for continued training. Waiting longer than two hours to eat results in 50 percent less glycogen stored in the muscle. The reason for this is that carbohydrate consumption stimulates insulin production, which aids the production of muscle glycogen. However, the effect of carbohydrate on glycogen storage reaches a plateau.
