Soybeans are rich in proteins

The soybean has been grown and used in China for more than 2000 years. Soybean [US] or soya beans[U.K] belongs to legumes and is introduced to West in the past century and has already become one of the best protein sources in the world.

Soybean oil

Soybean oil is comparable to other vegetable oils in its content of mono saturated fats [60%] and polyunsaturated fats [25%].
Soybean oil's polysaturated fatty acid profile include two very important essential fatty acids, namely linoleic acid and linolenic acid, which are not produced by the human body.
These fatty acids are required for the our health and they help in the absorption of vital nutrients by the body.
Biological processes like muscle contractions, growth of cells and blood pressure are achieved by the activity of an array of hormones. These essential fatty acids, functioning as precursors bring about the hormonal activity.
