The best answer to the question: In making recommendation for protein intake, the committee on DRI took into consideration that the protein in a normal diet would be:___, is: A combination of animal and plant sources.

Explanation:

Although there is no possibility of generalizing for all the people in the world the true amount of protein that is necessary, given that there are a lot of factors to take into account, it can be said that for the U.S population, the recommendation is for 0.8 gms per kilogram of body weight on a daily basis.

Although it is highly recognized that animal protein sources (meat, fish, poultry, etc) and dairy are the best sources of high-quality proteins, it has also been recognized that a large portion of the U.S population have turned towards vegetarianism and vegan lifestyles and thus, recommendations have adjusted to recognize that sources of good quality proteins can be meat, dairy and certain vegetable sources.
