Description
Soybean, also known as soya or soya bean, is a highly valued legume recognized globally for its dense nutritional profile and wide-ranging applications. Rich in plant-based protein, soybeans contain all essential amino acids and is widely consumed in various forms such as soya chunks, soy milk, tofu, roasted soybeans, and refined soybean oil. With a protein content of approximately 36–40 grams per 100 grams, it is a preferred dietary source for vegetarians and vegans.
In addition to protein, soybeans are packed with dietary fiber, calcium, magnesium, zinc, phosphorus, and iron. Soybean oil is commonly used in cooking and commercially traded, with terms like CBOT soybean oil, soybean oil rate, and soybean oil futures reflecting its global market demand. Soy milk is popular among individuals with lactose intolerance as a dairy substitute.
The nutritional value of soybeans extends to cardiovascular, metabolic, and musculoskeletal health. Its antioxidant and isoflavone content helps regulate blood sugar levels, support bone density, improve lipid profiles, and assist in hormonal balance, especially beneficial during menopause. Topical use of soybean oil may also contribute to skin health and hair vitality.
