Millions of people in this world are infertile and some scientists expect this number to rise with time. With regard to infertility in men, it is thought a person’s diet is one of the major factors suggested to be responsible for poor sperm quality. However, clinical trials have not been conducted yet to assess the effects of food and diet on the quality of sperms.
Now, a new study published in the journal Andrology indicates that adding tree nuts including walnuts, almonds and hazelnuts to a regular western diet can improve sperm quality in men by affecting DNA methylation in specific regions.
A western diet or western pattern diet includes a high intake of saturated fats, proteins (majorly from fatty meats), refined grains, salt, sucrose, alcohol and reduced intake of fibre.
