This fruit is a nutrient powerhouse with one of the highest ORAC ratings for non-herbal foods and has a low Glycemic Index.

• A. Watermelon
• B. Blueberries
• C. Mango
• D. Peanuts

Answer: (B)

Antioxidant strength and glycemic response are central here. ORAC measures how well a food can neutralize free radicals, and blueberries have one of the highest values among non-herbal foods thanks to their rich anthocyanins and other polyphenols. That makes them a nutrient powerhouse. They also carry a relatively low glycemic index, so they raise blood sugar more slowly than many other sweet fruits. In comparison, watermelon tends to have a higher glycemic impact, mango is sweeter with a higher GI, and peanuts aren’t a fruit and don’t offer the same antioxidant profile. So blueberries best meet both criteria.
