SOYBEAN

HISTORY

From the East Asia regime, the Soybean is from the legume family. They were first domesticated by Chinese farmers around 1100 BC. Soybean is among the major industrial and agricultural crop which is spread out throughout the world and in every continent. Brought to Ghana by the then Presbyterian missionaries in the year 1910, it is noted to be a “wonder crop” because of the impact it has in terms of health, economic and nutritional benefits gained from it, not only to Ghana but the world as a whole.

NATURE

The soybean is a native legume of East Asia, widely grown and consumed for its edible bean, which has numerous uses as well. The first stage of root growth for soybean occurs within the first 48 hours under favourable growing conditions. At the maturation stage, the first true leaves develop as a pair of single blades. It is noted that soybeans can fix atmospheric nitrogen due to the presence of symbiotic bacteria from the Rhizobia group.

NUTRITIONAL CONTENT

The wonder crop as it is noted has protein, oil and also a greater amount of amino acid in its makeup which helps in the eradication and reduction of malnutrition in the less privileged communities that do not earn enough income to enjoy animal proteins. The crop is a good source of protein for vegetarians and vegans thus can be used as a substitute to meat.

BENEFITS

1. Promote a healthy skin

Soybeans have been found to contribute to making one’s skin firmer and younger in appearance. According to nutritionists, soybeans help in promoting the production of collagen, an important part of skin’s elasticity. It also helps in reducing the appearance of sun and scars from sun burns.

2. May reduce cancer risk

Studies have shown that consumption of soy products may reduce the risk of breast cancer. According to observational studies, soybeans compounds, including isoflavones and lunasin may be responsible for cancer-preventive effects.

3. Alleviation of menopause symptoms

The isoflavones in soybeans may help alleviate symptoms associated with menopause. Research has indicated that daily intake of 135 mg of isoflavones for one week which is equivalent to 68 grams of soybeans reduces menopausal symptoms.

4. Bone health

Consuming soybeans may reduce the risk of osteoporosis in women who have undergone menopause. This benefit is also attributed to the presence of isoflavones.
