Watermelon
When you keep your body hydrated, you also keep your memory in perfect condition, as well as a stable mood. Also, watermelon helps you cool your body (through perspiration) in the summer months. The good news is that the water you need is not just in liquid form: you can also eat it.
Besides the fact that it provides you with an extra quantity of lycopene (that’s considered to be a cancer-fighting antioxidant), that protects your skin, watermelon is made up of 92% water. In addition, it’s a reliable help in lowering high blood pressure, being one of the richest natural sources of the amino acid L-citrulline.
Another bonus: research shows that when we eat foods that have a high water content, it helps us feel fuller, with fewer calories.
