The military is a setting where you can control several variables that would be far more difficult in other experiments. Say you want to test a food product on 1000 people. You need to factor in things like age, a person's diet, sex, pregnancy, previous health, physical activity, sleep, location, etc. when formulating such a study.
However, the military provides people of similar age, fitness, daily activity, etc. and it's easier to keep track of their diet and other factors that may be relevant to the results of such a study.
It's really difficult to conduct studies involving food, especially long-term, just because a person's life involves so many things it's hard to tell if there is an significant change (significant = relevant) good or bad.
