A pound of turnips supplies about 140 calories of energy, 4 grams (about 
r ounce) of protein, 0.2 gram of calcium, 0.14 gram of phosphorus, and 1.8 
milligrams of iron. It would furnish, therefore, 4 per cent of the energy a 
man needs daily, 4 per cent of the protein, 30 per cent of the calcium, 11 
per cent of the phosphorus, and 12 per cent of the iron. This is shown in the

One pound of asparagus supplies about 105 calories of energy, 8 grams 
(about i ounce) of protein, 0.12 gram of calcium, 0.2 gram of phosphorus, 
and 4.5 milligrams of iron. It would furnish, therefore, 3 per cent of the 
energy a man needs daily, 8 per cent of the protein, 17 per cent of the cal- 
cium, 13 per cent of the phosphorus, and 30 per cent of the iron. This is
