The Institute of Medicine recommends that, adults should get a minimum of 0,8 gramms of protein per kg of their body weight daily. Here is the calculation:
Your body weight in pounds divided by 2,2 = Your body weight in kg
Your body weight in kg times 0,8 = recommended amount of protein per day ( in gramms)
We know, plants food also provide protein, but these are not considered complete proteins because they do not provide all of the needed amino acids. The only one exception is soy beans and quinoa, these are complete proteins from non-animal sources. Beans, seeds, nuts and grains are very good sources of protein. We can make these proteins to be complete protein by combine them. For example with the incomplete proteins of rice and beans, we can make a complete protein.
