2. Powerful Antioxidant Properties
Star fruit contains quercetin, gallic acid, and epicatechin, which help:
- Neutralize free radicals.

3. Supports Heart Health

4. Aids Digestion & Weight Loss

- Low-calorie and high-fiber content help with satiety, aiding weight management.
5. Boosts Immunity
- Vitamin C enhances white blood cell production, strengthening the immune system.
- Antimicrobial properties may help fight infections (e.g., Staphylococcus and E. coli).
6. May Help Control Blood Sugar

- Bioactive compounds improve insulin sensitivity (beneficial for diabetics in moderation).
7. Supports Liver & Kidney Health
