In Snyder's Human Foods (1916) the official analyses of 163 common foods are given. They include practically everything that human beings eat, and only three are greater than chocolate in energy-giving power.
The result (2,538 calories per lb.) which we obtain by calculation is lower than the figure (2,768 calories per lb.) for chocolate given by Sherman in his book on Food and Nutrition (1918). Probably his figure is for unsweetened chocolate. The table below shows the energy-giving value of cocoa and chocolate compared with well-known foodstuffs. The figures (save for "eating" chocolate) are taken from Sherman's book, and are calculated from the analyses given in Bulletin 28 of the United States Department of Agriculture:
