Each year more than three million men deal with the embarrassing personal issue of erectile dysfunction. Put simply, erectile dysfunction is defined as the inability to get or keep an erection for sexual intercourse. The symptoms of erectile dysfunction can include reduced sexual desire, trouble getting an erection and trouble keeping an erection.

While many men turn to medication to solve this problem, healthy eating is a great alternative:

1. Dark chocolate
Dark chocolate contains flavonoids. The Flavonoids in dark chocolate are known for improving circulation. This is great for erections which can be the result of poor blood circulation. Flavonoids occur naturally and are known for helping to repair cell damage and provide protection from toxins in plants. There are numerous studies that show that flavonoids can have a similar impact on humans. Furthermore they also can help to lower blood pressure and decrease cholesterol, both factors in erectile dysfunction.

2. Pistachios
Pistachios might be one of the most powerful foods in the world when it comes to sexual performance. A recent study showed that men with erectile dysfunction that ate pistachios everyday for three weeks showed a major improvement with sexual issues including erectile dysfunction and overall sexual satisfaction. Pistachios contain a protein called arginine. This protein is known for helping the blood vessels to relax. Good circulation ultimately equals good sexual health.

3. Green vegetables
Most men were warned as kids to eat their vegetables. Here is another good reason. Vegetables like celery or spinach contain a high concentration of nitrates. Nitrates help to increase circulation. They are known as vasodilators, which simply means they increase the flow of blood by forcing the blood vessels to open up. Many of the erectile dysfunction pills on the market are based on the effects nitrates have on increasing blood flow to the penis.

4. Oysters
For years oysters have had a reputation for being an aphrodisiac. Now there is some science to back it up. Oysters contain high levels of zinc which play a major role in the production of testosterone. Low testosterone levels can be the cause of erectile dysfunction. Studies by the American Chemical Society show that oysters contain certain compounds that stimulate the release of sexual hormones.

5. Watermelon
Watermelon is a popular summer treat that may also help with a man’s sexual dysfunction. Watermelon is loaded with antioxidants that can improve erectile dysfunction. There are some studies that show that watermelon can have the same impact on erectile dysfunction that Viagra has. Watermelon is rich in phytonutrients. Also known as antioxidants, phytonutrients relax the blood vessels that supply an erection. This fruit can work wonders on your heart and sexual health.

6. Tomatoes
Adding a tomato to your meal could provide great benefits. Tomatoes contain lycopene, a phytonutrient that is good for circulation. It is also good for sexual health. A number of studies show it is best absorbed when mixed with an oily food like avocado or olive oil. Throwing some tomatoes on a salad may be a great way to fight erectile dysfunction.
