The short answer is yes it can, but it depends...
Erectile Dysfunction is caused by the lack of blood flow to the penis, and there are a few foods that can help to aid this problem. However, none of them are scientifically proven to prevent Erectile Dysfunction, but they can aid blood flow around the body. Erectile Dysfunction is predominately caused by the narrowing of the blood vessels to the penis. Many foods can act as a vasodilator and reserve this narrowing.
Watermelon – Contains an amino acid called Citrulline which improves blood circulation to the heart and around the body. It also relaxes blood vessels in a similar way to Viagra, which aids in both attaining and maintaining an erection.
Blueberries – A Harvard study, published in January 2016, has reaffirmed the benefits that blueberries can have as a dietary-fix for Erectile Dysfunction. Like watermelon, blueberries can relax blood vessels to aid the flow of blood around the body which helps in attaining and maintaining an erection. This is due to blueberries being rich in Flavonoids. The study showed that regularly consuming three groups of flavonoids (anthocyanins, flavones and flavanones) in “just a few portions a week” can reduce the chances of the onset of Erectile Dysfunction by 10%. Red Wine is also thought of a good source of flavonoids.
Nuts – Rich in multiple nutrients that have many benefits to sexual performance. Nuts are high in L-Arginine which can help to treat Erectile Dysfunction by increasing blood circulation. Nuts are also rich in Zinc, which the body uses in the production of sperm. High Zinc intake will therefore help in the production of healthy sperm.
Broccoli – Known to act a vasodilator that will aid in the blood supply to urogenital systems. Broccoli is rich in phytochemicals which allow it to have this effect on blood vessels in the body.
Vitamin C – Found in most fruit and vegetables, Vitamin C is used in the production of collagen. The body uses collagen for the maintenance of arteries. A lack of Vitamin C in your diet can lead to arteries narrowing quicker. Collagen production naturally decreases with age, so a rich Vitamin C diet is key.
B Vitamins – These vitamins play a key role in cholesterol maintenance, which will reduce blood flow around the body if levels are too high. The key Vitamins are B3, 5 and 12. Most seafoods are high in all three of these Vitamins. Meats are also a good source of Vitamin B3. Mushrooms, cheeses and eggs are good sources of Vitamin B7. Liver, cereals and red meat are good sources of Vitamin B12.
All these foods should be included as part of healthy diet and are no guarantee to prevent or reverse the effects of Erectile Dysfunction.
