Beetroot is also a mineral-rich food that can contribute to overall health. But its greatest benefit is its abundance of nitrates that the body converts into nitric oxide. That's good. Greater levels of nitric oxide translate directly to increased blood flow to all areas of the body. Athletes have been realizing the benefits of this for several years now. Greater blood flow allows more oxygen to be delivered to various parts of the body, which enhances endurance. Naturally, this is of obvious benefit to sexual health, as greater blood flow to the penis will result in a fuller and sustained erection. As a result, beetroot is becoming a common way to naturally treat sexual dysfunction in men.
