Low carbohydrate diets are now craze in U.S.A. Fast food stores even offer hamburgers in lettuce rather than in buns (still with fats of meat and sauces). Breads and pastries modified for lower carbohydrates are now making fortunes for suppliers. "Low carb salads", still drenched with high fat dressings, are offered for "dieting."
This is a costly, stupid, perhaps health threatening fad.
When I was growing up, I did not understand that biblical quotation of "Man does not live by bread alone", attributed to Moses (old testament, torah) and Jesus (new testament). Well, I understood that message was meant to be "People have spiritual as well as physical needs." But I had no idea how people could live very long on bread. At that time, I was used to spongy white bread with no character.
Somewhere along way, I learned about whole grain breads, and how peasants through centuries had lived mostly on dark breads that Marie Antoinnette would have rejected, with occasional fortifications of cheese, eggs, sometimes meat. Peasants tended to eat vegetables, but knights and nobles often dismissed such as "farmers' fare", preferring lots of meat, alcoholic beverages, pastries. Few people lived long in those days, so statistical studies of life span versus diet were not performed. (Statistics were not well known.)
So I read up on bread recipes, found a few health gurus who argued for blends of whole grain wheat, cornmeal, rye, and soy flour. A fairly recent development is triticale, a long sought hybrid of wheat and rye. Why these blends? It turns out that grains and legumes can provide all balanced protein that we need, without meat. Verrrry interesting! Also, such blends contain valuable dietary fiber.
The prayer, "Give us this day our daily bread", is now explained. Properly made, bread really can be "the staff of life."
I have learned to love Asian foods that make heavy use of soy beans, such as tempeh and tofu with noodles and stir fry vegetables. I usually am turned off by soy based foods that pretend to be something else, such as soy burgers, soy cutlets, soy cheeses. In fact, fake foods not only can taste far from real, but those which contain Hydrolyzed Plant Protein (HP) inflame my tongue and cause me anxiety, just as foods with a lot of Monosodium Glutamate (MSG).
