Depending on the controls, this could suffer from the same flaw as all the other “nuts do X for your health” studies - the studies only detected the benefits of being wealthier and having a better diet.
There really should be a blanket caveat on all health research reporting:
This was probably paid for by someone with a vested interest
The sample size probably was too small and confounding factors not controlled enough to draw the reported conclusion
A later study will probably find no effect
Funded by the International Nut and Dried Fruit Council.
83 person sample. No placebo so no blinding. No diet controls. Significant differences between control and test groups. No report of sexual frequency. No comparison of sex hormone levels. Extremely small difference in mean change reported for the measures.
The randomized controlled trial, which was recently published in Nutrients, showed a significant increase in the orgasmic function (P = .037) and sexual desire (P = .040) of men of reproductive age who received the nut intervention in comparison with an age-matched control group.
So, self reported or what?
Because I know some people who wouldn’t at all mind helping.
This was a tiny study (43 men eating nuts compared to 40 men who did not) and there were many variables which were not controlled. They did not have a uniform diet in which all the men ate the same foods in the same amounts except for the nuts, for example. And other factors like over the counter medications were also not controlled.
So what this study shows is - nothing useful. At best, it shows some areas which could benefit from a lot more study. It’s certainly not worth an article here for anything but click bait.
