5. Grapes

If you do not suffer from blood sugar spikes, then eat grapes. These berries are high glycemic, which means that grapes should be avoided by people suffering from diabetes. There are plenty of benefits, though. Grapes prevent heart disease, improve digestion and reduce bone health issues and fatigue. Non-organic grapes, unfortunately, have over 50 pesticides. Most of them are known to disrupt hormones or cause cancer. Give preference to organic grapes or do not buy grapes at all.
