Source of beta carotenes

Star fruit are a source of beta carotenes which when converted into retinol or Vitamin A help in maintaining good vision and appetite. Other polyphenolic antioxidants contained in the fruit act as antimicrobials against E.coli, Klebiesella sp., Staphylococcus aureus and Pseudomonas aeruginosa. A single cup of Carambola provides 1 percent each of Vitamin A and E.
