Encouraging men to eat a healthier diet may have just got a bit easier. Epidemiological evidence now clearly supports a role for several dietary factors in the pathogenesis of erectile dysfunction.The prevalence of erectile dysfunction is surprisingly high. A review of general practice patients in Perth, Australia in 2000 found almost 40% of men reported some erectile difficulties. Figures on prevalence vary but before the age of forty it is uncommon, however it more than doubles for men over 50 and continues to rise quickly as men age. Over 70% of men over 70 are having problems.Exercising regularly and staying lean are clearly beneficial. Now diet is proving its potency. Men with a dietary pattern high in fruit, vegetables, nuts, whole grains, and fish but low in red and processed meat and refined grains are less likely to have difficulty achieving and maintaining an erection.The Mediterranean diet has been proposed as a healthy dietary pattern based on evidence that it is associated with lower all-cause and disease-specific survival. The assumption is that these beneficial effects are primarily due to improved cardiovascular function although other mechanisms are likely to contribute.Type 2 diabetic men whose diets most closely match the Mediterranean style of eating have the lowest prevalence of erectile dysfunction and are also more likely to be sexually active.We can now show that the prescription of a healthier diet for men with erectile difficulties improves performance, especially in men with obesity of metabolic syndrome. In clinical trials, the Mediterranean diet was more effective than a control diet in ameliorating erectile dysfunction or restoring absent erectile function.ReferenceDietary Factors, Mediterranean Diet and Erectile Dysfunction.

BPA and Men: A Bad Match
Bisphenol-A (BPA) is an industry chemical used to make polycarbonate plastic resins, epoxy resins and other products. New evidence suggests that BPA can cause sexual dysfunction in men, especially those exposed to high levels at work. Investigators from Kaiser Permanente’s Division of Research in Oakland, CA, who reviewed the health records of 550 factory workers in China found that those who worked with BPA were four times more likely to report some type of sexual dysfunction than were men in the factory who didn’t work with the chemical.
This is not the first study to link BPA to harm in humans. Other research has demonstrated developmental changes in animals exposed to the chemical. In the new study, 15.5% of men exposed to BPA reported erectile dysfunctionmore than half the time compared to only 4.4% of men who weren’t exposed to BPA. In addition, 13.9% of the men exposed to BPA complained of difficulty ejaculating compared to 2.5% of men who weren’t exposed. However, the BPA levels in question were about 50 times what the average individual experiences. Don’t look for any change in policies pertaining to BPA as a result of this study. More evidence from other human studies will be needed to determine what levels, if any, of BPA are safe for humans.
Until we know more about any human health risks, I recommend avoiding plastics containing BPA. Substitute those made with polypropylene (#5 PP), high-density polyethylene (#2 HDPE), and low-density polyethylene (#4 LDPE). You can also reduce your exposure by buying foods and beverages frozen or packed in glass jars or bottles instead of cans lined with an epoxy containing BPA.
