The good amount of potassium and magnesium that is present in watermelons is very beneficial in terms of preventing blood clotting. Potassium is considered a vasodilator, meaning that it releases the tension of blood vessels and arteries, thereby stimulating increased blood flow and reducing the stress on the cardiovascular system. The carotenoids present in watermelon also prevent hardening of artery walls and veins, thereby helping to lessen the chances of developing blood clots.
Olives are rich in compounds that are commonly linked to act as anticoagulants to thin the blood, which reduces the chances of blood clots developing and dangerously blocking the flow of blood. Aside from that, the same compounds also eases blood vessel tension and dilates the blood vessels, which reduces the strain on the heart and increases blood flow around the body in a healthy way.
