According to a study, anthocyanins also have a role as a pharmaceutical ingredient since they possess antioxidative and antimicrobial activities. In addition, the pigment can also help improve visual and neurological health and decrease the risk of having various non-communicable diseases.
Antioxidants are chemical compounds that counteract unstable molecules called free radicals. Free radicals damage DNA and parts of our cells. They are inevitable and encountered naturally by our body because they are byproducts released when we exercise or when our body fights off intruders.
Antioxidants like anthocyanin disarm free radicals and help control them, which can slow the aging process and fend off cancer and heart disease.

Adding fiber to your diet does not only help you in achieving your weight goals but also stabilizes your blood sugar and cholesterol count. This benefit results from fiber combining with cholesterol and carbohydrates, preventing them from being absorbed or being digested quickly. High amounts of fiber will also prevent constipation and promote a regular, healthy digestive tract.

Soybeans can also cause digestive symptoms in some people since they are high in fermentable oligo-, di-, monosaccharides, and polyols (FODMAPs).
Large amounts of soybeans could also harm people with thyroid conditions. Soy isoflavones have little to no impact on the general population but could be a cause for concern for those with thyroid problems.
