Other dairy sources include milk, cheese and eggs. A cup of milk will contain 120 calories (2% milk) and 8 grams of protein. One slice of cheddar cheese contains about 115 calories and 7 grams protein (but be careful of the saturated fat). One medium sized egg contains about 65 calories and 6 grams protein.
Daily protein requirements vary by person according to age, body weight and your individual health circumstances e.g. whether you are dieting. There are many online calculators that can help you calculate your own ideal intake.
What makes the above sources of protein even more desirable is that they are very healthy for other reasons as well. For instance, lentils, peas and spinach are also jam packed with vitamins and anti-oxidants. Soybeans are unique too, in that they contain complete protein (i.e. all amino acids). So now there's yet another reason to eat these great foods!
