Also, soy is the only plant food which give complete protein(contains all essential amino acids).

Advantages of Soy:

  • Contains Antioxidants: Antioxidants are compounds that repair and prevent cell damage caused by day to day activities, pollution etc. Also, it prevents the formation of free radicals which have the potential to cause damage to DNA.
  • Protection against cancer: Studies has shown some results that the soluble fibres protects from gastric cancers. Also, isoflavons, which are secondary vegetable substances acts as oestrogen in the body and have protective functions. It is claimed to have protections against cancer associated with uterus, prostrate and breast.
  • Prevents Osteoporosis: Protein content in soy aid in the absorption and retaining of calcium content in bones.[Osteoporosis is a condition in which bones are weakened due to several reasons like reduced Ca absorption. At critical cases, minute perforations are made ont the bone which result in breakage.]
