Can food cure or reverse erectile dysfunction? No single food cures it, but a healthier overall diet can help: in trials, a Mediterranean-style diet brought back normal erections for some men with obesity or metabolic syndrome, and men who eat more fruit develop ED less often. Diet works slowly, and only on the causes it can reach.
Can a diet cure erectile dysfunction?
It can reverse ED for some men, but "cure" overstates it. healthdirect says plainly that ED sometimes can't be completely cured, and lists causes that range from clogged arteries and obesity to nerve damage, hormones, medicines and stress (healthdirect); food reaches only some of them. Still, Healthy Male says you might get back to normal erectile function "simply by taking better care of yourself" — a healthy diet, regular exercise and less drinking, smoking and drug use (Healthy Male). Regular exercise, weight loss and quitting smoking have trial evidence of their own, covered in natural remedies for erectile dysfunction.
What does the Mediterranean diet do for erections?
In the best trial, it restored normal erectile function in more than a third of the men who followed it. Sixty-five men with ED and the metabolic syndrome were advised to follow either a Mediterranean-style diet or a control diet for two years; the diet group ate more fruit, vegetables, nuts, whole grains and olive oil, and 13 of 35 reached a normal erectile-function score, against 2 of 30 on the control diet (Esposito et al., 2006). In men with newly diagnosed type 2 diabetes followed for about eight years, a Mediterranean diet did not restore erections, but it slowed their decline compared with a low-fat diet (Maiorino et al., 2016). Both trials come from the same research group in Naples.
Do fruit and vegetables lower the risk of ED?
In large studies, modestly. Among 25,096 American health professionals followed for 10 years, men with the highest intake of three flavonoid groups (anthocyanins, flavanones and flavones) were 9–11% less likely to develop ED, and men who ate the most fruit 14% less likely; among single foods, citrus and blueberries stood out, and the link held only in men under 70 (Cassidy et al., 2016). Tea contains flavonoids too, but its catechins belong to the flavan-3-ols (Braicu et al., 2013), a group that showed no link with ED in that study.
In the same group of men, those whose diet was closest to the Mediterranean pattern had a 22% lower risk of ED if they were under 60 (Bauer et al., 2020). These are associations, not proof: men with the highest flavanone intake also smoked less and exercised more, and the authors call for trials.
Which foods are worth eating?
The pattern matters more than any one food. The Australian Dietary Guidelines recommend a wide variety from the five food groups, with plenty of vegetables and legumes, mostly wholegrain cereals, and oils, nut butters and avocado in place of saturated fats (Eat for Health). For men aged 19 to 50 that means six serves of vegetables and two of fruit a day (Eat for Health). The Naples diet was built on the same foods, plus walnuts. Single foods sold as "natural Viagra" are another matter:
| Food | What has been tested |
|---|---|
| Watermelon | Its citrulline was tested as a supplement; the fruit itself was not. |
| Nuts | Pistachios raised scores in 17 men over three weeks, with no comparison group (Aldemir et al., 2011). In a 14-week trial of 83 healthy young men, 60 g of mixed nuts a day improved orgasm and desire but not erectile function (Salas-Huetos et al., 2019). |
| Pomegranate juice | One trial; not significantly better than placebo (Forest et al., 2007). |
| Beetroot, garlic, dark chocolate, bananas | No randomised trial of the food on its own in men with ED — see the ranking in natural alternatives to Viagra. |
How long does a change in diet take to work?
Longer than most men hope. The diet trials that showed a benefit measured it after two years; the diabetes trial ran for about eight.
What should you cut back on?
Processed and fried foods high in saturated fat, added salt, added sugars and alcohol, which the guidelines ask everyone to limit. Alcohol and smoking are on healthdirect's list of causes of ED, and in a Catalan study of 440 men at cardiovascular risk, more alcohol went with more ED, while eating nuts more than twice a week or vegetables every day went with less (Ramírez et al., 2016).
Is there a food to avoid with ED tablets?
Yes: grapefruit. Grapefruit juice raised sildenafil levels by about 23% in a study of 24 men, and its authors advised avoiding the combination (Jetter et al., 2002); the Cialis consumer medicine information names grapefruit juice too. See grapefruit juice and Viagra and foods to avoid with Viagra.
The short answer
Eat the way the Australian guidelines describe — mostly plants, fruit every day, less processed food and alcohol — and pair it with exercise and weight loss. For some men that reverses ED over months to years; no food works like a tablet. If erection problems persist, see a GP: ED is often the first sign of heart disease.
