"Nutritionists suggest that a normal adult male should receive about seventy grams of protein a day, with larger amounts going to pregnant women, children and the sick. Of the total protein requirement, about thirty grams should be of animal origin. ...only one quarter of the world's people receive more than thirty grams of animal protein daily; many receive far less... the present total world deficit is about five million metric tons, one quarter of a year's total supply."
