Vegetarians always ask about getting enough protein. But I don't know any nutrition expert (who) can plan a diet of natural foods resulting in a protein deficiency, so long as you're not deficient in calories. You need only 5 or 6 percent of total calories in protein... and it is pratically impossible to get below 9 percent in ordinary diets.
