Erectile dysfunction, the medical name for impotence, is "very common, particularly in men over 40", according to the NHS page on erectile dysfunction. The same page says healthy lifestyle changes "can sometimes help", and eating a healthy diet is one of them. So a diet plan can't promise to stop impotence. What the studies support is narrower, and this article sets it out before getting to the plan itself.
What the NHS lists first
The NHS says most men occasionally fail to get or keep an erection, usually because of stress, tiredness or drinking too much alcohol. If it happens often, the cause may be a condition such as high blood pressure, high cholesterol, diabetes, depression, anxiety or hormone problems. Its advice is to see a GP or go to a sexual health clinic if erection problems keep happening, because it might be a sign of a health condition that can be treated.
Its list of lifestyle changes has five items: lose weight if you're overweight, stop smoking, eat a healthy diet, exercise daily and try to reduce stress and anxiety. It also says not to drink more than 14 units of alcohol a week. Diet is one line on that list.
What the trials and cohort studies found
One randomised trial tested this directly: Esposito and colleagues (JAMA, 2004). It took 110 obese men aged 35 to 55 who had erectile dysfunction but no diabetes, hypertension or hyperlipidaemia. The 55 men in the intervention group got detailed advice on losing 10% or more of their body weight by eating fewer calories and being more active. The 55 men in the control group got general information about healthy food choices and exercise.
After two years, the average erectile function score (IIEF) in the intervention group rose from 13.9 to 17, while the control group stayed flat at 13.5 to 13.6. Seventeen men in the intervention group reached a score of 22 or higher, against 3 in the control group. The authors concluded that lifestyle changes were associated with improvement in about one third of the obese men. Food and exercise were changed together, so the trial does not separate the effect of diet alone.
A larger, observational picture comes from the Health Professionals Follow-up Study (Bauer et al., JAMA Network Open, 2020). It followed 21,469 US male health professionals for an average of 10.8 years. Men younger than 60 with the highest Mediterranean diet scores had a lower risk of developing erectile dysfunction than men with the lowest scores (hazard ratio 0.78). The link was weaker in older men: 0.82 for ages 60 to under 70, and 0.93 for 70 and over. This is a cohort study, so it shows an association, and the authors' own wording is that a healthy dietary pattern "may play a role".
A 2018 review in Sexual Medicine Reviews (La, Roberts and Yafi) covered 13 studies on diet and erectile dysfunction. It concluded that erectile dysfunction "appears to lessen" in men who follow a Mediterranean diet, and that obese and overweight men who lose weight on low-fat, low-calorie diets seem to see improvements. It also said more prospective and randomised trials are needed.
Turning that into a diet plan
Start with what's already on your plate (rice, bread, vegetables, protein, fruit) and adjust the order and portions rather than replacing everything at once. If you're overweight, the Esposito trial's target was a loss of 10% or more of body weight through fewer calories plus more activity, so portions matter as much as food choice.
For the plate itself, the NHS eight tips for healthy eating give a usable frame. A portion of fresh fruit or vegetables is 80g. Aim for at least 2 portions of fish a week. For protein, rotate eggs, lentils, chicken and fish instead of eating the same one every day.
Drinks get skipped in a lot of diet advice. The NHS says the government recommends 6 to 8 glasses of fluid a day. All non-alcoholic drinks count, but water, lower fat milk and lower sugar drinks, including tea and coffee, are the healthier choices. Fruit juice and smoothies should stay at 150ml a day combined, because even unsweetened ones are high in free sugar.
Where dates fit
Dates are one fruit choice inside this plan, not a fix for erection problems. On PubMed, the studies linking dates to erectile function are in rats (PMID 38483941, 35644948) or used date palm pollen or capsules (PMID 35388309, 35168636); none tested eating dates as part of a diet in men with erectile dysfunction. Per 100g, USDA FoodData Central lists Medjool dates at 277 kcal, 66.5g total sugars, 6.7g fibre and 696mg potassium. The NHS counts 30g of dried fruit, including dates, as 1 of your 5 A Day, but says it should be eaten at mealtimes, not as a snack between meals, to reduce the impact on teeth (NHS 5 A Day: what counts). Since the Esposito intervention included eating fewer calories, count dates in your daily total like any other food.
