4. You’ll have healthier kidneys
Grapes contain powerful antioxidants like anthocyanin (gives grapes their red to purple color) and resveratrol. Both play a key role in fighting off free radicals that could enter the kidneys causing infections and disease. These antioxidants also work hard to flush out waste products like uric acid.
The National Kidney Foundation recommends a daily consumption of 15 grapes for maintaining good kidney health as part of a balanced diet.
