3. Improves Digestive Health
- Fiber Benefits: Dietary fiber in peanuts promotes healthy digestion and prevents constipation by adding bulk to the stool and facilitating regular bowel movements.
- Gut Health: Peanuts support beneficial gut bacteria, contributing to improved gut health and overall digestive function.
4. Boosts Brain Health
