Sure, you’ve heard that a ballooning waistline can lead to health complications, including erectile dysfunction. By exercising regularly and eating better, you can fight back against this weight-gain induced ED. But when you’re making these positive lifestyle changes, are there any foods you can introduce into your diet that might help your chances of beating ED?

While no food group is going to help you to overcome ED singlehandedly, introducing these three foods into your diet may give you the fighting chance you need.

Leafy Greens: Leafy veggies such as spinach, celery, and lettuce are chock full of nitrates, an extremely effective vasodilator. In plain English this means that these green vegetables help to open up blood vessels and facilitate healthy blood flow. When blood can quickly reach the penis, this makes it easier for the body to achieve an erection.

Pistachios: These little nuts are rich in protein, which has been found to help improve sexual health. In fact, pistachios are so efficient at getting protein to the body that researchers have found that men with ED who ate pistachios every day for three weeks experienced a significant improvement in erectile health. This is because the protein in pistachios helps to relax blood vessels, improving blood flow.

Watermelon: Watermelon has been found to be so effective at helping men with ED that many have taken to calling the delicious fruit “Nature’s Viagra.” This is because watermelon is rich in phytonutrients, a helpful antioxidant. What makes these phytonutrients so efficient at fighting ED? You guessed it; they relax the blood vessels.
