This amount of milk will supply one-third to one-half the total daily protein requirement for the average person. Nuts are so rich in these precious proteins, practically identical with those of milk, that the protein found in 20 ounces of milk may be furnished by 2 ounces of peanuts, 2-1/2 ounces of butternuts, 3 ounces of almonds or beechnuts, 4 ounces of English walnuts, or filberts, 5 ounces of pinenuts (pinons) or hickory nuts, 5-1/2 ounces of pecans, 6-1/2 ounces of chestnuts or chinquapins, or half a pound of acorns. The nut is one of the most important and interesting of all foodstuffs for the reason that it presents in concentrated form the most valuable and easily digestible of proteins. It is for this reason that the farmers of Northern Italy are able to thrive on a diet of which the chestnut is the staple. For the same reason 300,000 Pacific Coast Indians prospered for centuries on a diet consisting chiefly of acorns and pinenuts. In recent times, one of these Indians was known to be living at the age of nearly 140 years, and the farmers of the West and South before they had destroyed with axe and fire the splendid oak forests of pioneer days, depended chiefly on mast to fatten their hogs. The acorn was their chief source of protein, which is as necessary for a hog as for a college professor.
