Pistachios & erectile function

Your wife complains that you’re always nibbling on pistachio nuts? Well, explain to her that you are not mindlessly snacking, but maintaining your sexual vitality. Yes, a Turkish study appears to have linked the eating of oleaginous plants, such as pistachios, to improvements in men’s erectile function.  

Rich in protein, fibre, vitamins and antioxidants, almonds, pistachios and other nuts have come back into the limelight over the last decade. In 2003, the American FDA (Food & Drug Administration) went so far as to say that, "Scientific evidence suggests, but does not prove, that eating 40g per day of most nuts,] as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease." But today’s news revolves around another property that the Turkish research team appear to have discovered.

The researchers evaluated the impact of eating Antep pistachios on erectile function. In total, 17 patients suffering from severe erectile dysfunction for at least twelve months ate 100g of pistachios per day over a three week period. For each of these men, scores on the International Index of Erectile Function (IIEF-15), penile color Doppler ultrasound (PCDU) parameters, and the level of serum lipid levels were all measured both before and after the dietary changes.

The result of this pistachio-rich diet: erectile function increased by 36±7.5 to 54,2±4.9, the flow of blood through the penis  measured with Doppler increased from 35.5±15.2 to 43.3±12.4 cm/s and the blood cholesterol level decreased significantly , while the “good HDL cholesterol” increased.

For the study authors there is no doubt.  "We demonstrated that a pistachio diet improved IIEF scores and PCDU parameters without any associated side effects in patients with ED. Furthermore, the lipid parameters showed statistically significant improvements after this diet. "

That being said, studies on a much larger group of patients with longer-term follow-up will be necessary to definitively confirm such effects. It should also be noted that in the absence of the very important “placebo group,” with patients eating “false pistachios” or another food,” it isn’t possible to isolate benefits coming solely from the pistachios. Nevertheless, there’s no harm in trying… without getting into over the top consumption of pistachios of course !
