How many of us have never complained about a meal that we were served? Ditto.
Yet most soldiers have always had a reason to complain. Since the beginning of organized military, feeding the soldiers has sometimes been such a huge task, that keeping them healthy, satisfied, and full, ranked last priority (if at all) on the mess hall to-do list.
Back in the day, and even now, military meals have either been ignored, completely dismissed, or the brunt of hundreds of jokes.
A former Veteran told me that when he was in service 47 years ago, most cooks and meals were referred to as, "Gut Cheater". Another man at a VFW dinner told me, "The word was, and still is, 'anything will go down with Tabasco'." A round of laughter broke out as those at my table joked about military meals of the past.... if they could be called "meals". Nutrition was never a concern, but filling the gut was the goal even if it was not always possible. Overweight soldiers were unheard of because overeating and lack of exercise just didn't happen. And many had suffered starvation.
These days, however, body fat is a concern for the military. According to Jim Gourley via blog: http://ricks.foreignpolicy.com, "...one in every three service men or women are obese".
Even if overeating is not the culprit, lack of exercise, cheap, low-quality food, and available junk food is.
