I found the following passsage in my Biology textbook for a college intro to Biology course.
"The incorporation of fixed nitrogen by plants into proteins and other organic substances has a major impact on human welfare because the most common form of malnutrition in humans in protein deficiency. The majority of people in the world, particularly in developing countries, have a predominantly vegetarian diet and thus depend mainly on plants for protein. Unfortunately, many plants have a low protein content, and those proteins may be deficient in one or more amino acids that humans need from their diet."
In literature promoting veganism I've read that protein deficiency is extremely rare. I believe I actually read, as long as caloric needs are met, it is impossible to have a protein deficiency.
I'm having a difficult time believing that my biology textbook would lie to me. Could the protein deficiency in developing countries be caused by insufficient calorie intake?
