Sweet potato, especially the purple variety, is packed with antioxidants. Antioxidants help neutralize free radicals in the body, reducing the risk of chronic diseases such as heart disease and cancer.

4. Promotes Eye Health

Due to its high concentration of beta-carotene, sweet potato is beneficial for eye health. Beta-carotene is converted into vitamin A in the body, which is crucial for vision and eye health, helping to prevent conditions such as macular degeneration.

5. Strengthens the Immune System

The antioxidant and anti-inflammatory properties of sweet potato help strengthen the immune system. Vitamin C, present in good amounts, is essential for the proper functioning of the immune system.
