Consuming a diet that includes plenty of fruits, vegetables, fish and whole grains may improve erectile dysfunction, reports Harvard Health Publications. Limiting intake of red meats, processed meats and refined grains is helpful as well. Dark chocolate, pistachios and watermelon are specific foods that researchers believe ameliorate erectile dysfunction issues, notes Healthline.
Erectile dysfunction is related to poor blood flow, so keeping the blood vessels healthy reduces the risk of vascular problems, including ED, explains Healthline. Eating foods that help control blood levels of cholesterol, sugar and triglycerides help men keep their vascular systems in good shape, as does maintaining a healthy body weight. It is best to limit alcohol and drug use, as these substances can cause or worsen ED.
Research indicates that antioxidant compounds called flavonoids concentrate nitric oxide in the blood, which increases blood flow essential to good erections, states Healthline. Dark chocolate is rich in flavonoids, so eating this in reasonable quantities may help ED. Results of another study indicate that men who include pistachios in their diets for several weeks have improved erectile function as well as better cholesterol and blood pressure levels. Studies reveal that watermelon contains a compound called citrulline, which helps relax blood vessels and improve blood flow, an effect similar to that provided by ED medications.
