I started thinking about ‘early man,’ back in cave days. Humans evolved
(perhaps) from the earlier ape-like life forms and developed into what
we today call ‘modern man.’ At the beginning, as well as through most of
the process, man was a hunter-gatherer, taking what foods he could as he
found them, and eating them on the spot due to lack of containers (very
earliest man,) or at least that same day due to lack of food
preservation knowledge (later man.) Typically, a meal would be of a
single food, eaten until either finished, or he was satiated and the
remainder eaten later the same day. Usually, a single food type would be
consumed each day. And yet mankind developed and evolved. It wasn’t
until MUCH later in the development of mankind that we began to
differentiate breakfast foods from dinner foods. And is this done more
because of taste or energy requirements at certain times of the day,
than health?

No one disputes the need for eating all of the food groups, but is
there ANY scientific proof that man needs to eat ALL of the basic food
groups EVERY day to maintain good health, or can single groups be
consumed on different days within a short time of each other and produce
the same results?
And about these food groups….. in the west we break them down into 4
groups. (Seven if you add caffeine, nicotine, and chocolate.) But in
Asia, the groups are very different. One must eat foods from; the
mountain, sea, field, and forest. And at least 7 different foods must be
consumed at each meal to maintain good health. Now, I realize that
scientifically, we are eating the basics, (protein, carbohydrates, fats,
etc.) and getting the vitamins and minerals that the body requires
regardless of which system we follow. But my question is, do we really
need to eat these ALL AT THE SAME TIME? Have any studies ever been done
on this question?
Also, science aside, what are YOUR opinions?
