Eating tree nuts every day can improve sperm quality, the study found


In short, men should start eating more nuts.

A recent study found that consumption of tree nuts – almonds, hazelnuts and walnuts – changes the quality of semen.

The study used 72 healthy male participants who reported following a “Western-style diet,” typically consisting of red meat and processed foods. Diet is considered to be one of the lifestyle and environmental factors that affect semen quality by researchers.

At the end of the trial, it was found that those who integrated almonds into their diet showed methylation of 36 genomic regions of sperm DNA – a biological process required for normal growth – that was “significantly different” from the control, with 97.2% displaying hypermethylation from those areas. doing.”

According to the researchers, the findings “provide first evidence that adding almonds to a Western-style regular diet affects semen DNA methylation in specific areas.”

“This work shows that sperm have some sensitive regions of the epigenome that respond to food, and that can alter sperm and lead to its ability to fertilize,” said lead author Albert Salas-Hutos in a press release.

The new research, conducted by the University of Rovira i Virgili, the Pere Virgili Institute of Health and Health and CIBROBAN, and the Human Nutrition Unit of the University of Utah, expanded on previous 2018 studies conducted by researchers at the University of Utah and the Spanish The University of Virginia, which regularly found men to include almonds in their diets, found “significant improvements in sperm count, viability, motility and morphology.”
