Carver's concern was the promotion of alternative crops to the monoculture of cotton cultivation, which had depleted the soil. Carver advocated the planting of nitrogen-fixing crops, such as peanuts, sweet potatoes, two Afrikan crops, and the Asian soybean. These crops would both nurture the soil, and also provide nutrition for poor families. However, Carver primary and secondary foci was the peanut and sweet potato respectively. He developed and promoted about 100 products made from peanuts that were useful for the farm and house. He produced such items as cosmetics, dyes, paints, plastics, gasoline, nitroglycerin, axle grease, buttermilk, bleach, chili sauce, , fuel briquettes, ink, instant coffee, linoleum, mayonnaise, meat tenderizer, metal polish, paper, plastic, pavement, shaving cream, shoe polish, talcum powder, synthetic rubber, and wood stain. Carver in his 1922 sweet potato bulletin listed many recipes. Carver did the least of his work on the soybean. Perhaps he was aware of its anti-nutritive elements when not properly prepared or consumed.
When I first made major dietary changes, the soybean was championed as the Superfood of Health. Only after eating more than my fair share of soy, which was made to imitate every possible meat, did I realize how harmful soy was. After lengthy soaking and cooking do soybeans become edible. This process produces tofu. Other fermented soy products are tempeh, miso, and natto. Unfermented soybeans are the problem. In their natural form, soybeans contain phytochemicals with toxic effects on the body. Soybeans three major anti-nutrients are phytates, enzyme inhibitors and goitrogens. According to Dr. Mercola, these anti-nutrients are the way nature protects the soybean plant so that it can live long enough to effectively reproduce--they function as the immune system of the plant, offering protection from the radiation of the sun, and from invasion by bacteria, viruses, or fungi. If they are not removed by extensive preparation such as fermentation or soaking, soybeans are one of the worst foods a person can eat.
What health problem are related to eating unfermented soybeans? Contrary to popular belief, thousands of studies have actually linked unfermented soy to malnutrition, digestive distress, immune-system breakdown, thyroid dysfunction, cognitive decline, reproductive disorders and infertility—even cancer and heart disease. There's more, soybeans have also been linked to PMS, endometriosis, ADD and ADHD, and loss of libido. Damn, seems like I was better off before I changed my diet. I'm just saying.
