One of the main components of vegetarian high-protein diet is non-meat from protein. In short, high-protein foods include lean meat, beef is the best, and eggs, beans, milk and fish can be used. In this diet, it is recommended to replace meat products with eggs. Eggs are a source of protein, comparable to meat, poultry or fish. Of course, dairy products can also be used as a source of protein and calcium for vegetarians. But vegans who don't eat eggs and dairy products can only find other sources in protein. When eating specifically, you can look at the same food package and look at the nutrient composition table. There are two most commonly used types: wheat and beans. Oats, soybeans and their products are recommended.
