Watermelon

Watermelon has so many health benefits, starting with hydration. It’s 92% water, and since food provides about 20% of your fluid intake, eating water-packed snacks like watermelon can help you avoid subtle, headache-spurring dehydration, London says.

What makes watermelon an extra great hydration helper is that it’s also a source of potassium and magnesium, two minerals that function as electrolytes to help balance fluid levels and offset excess sodium in your diet. And don’t forget about other melons like cantaloupe and honeydew, which are also bursting with H20, electrolytes and a good amount of vitamin C.
