EE.UU: estudio muestra que consumo de nueces mejoraría fertilidad masculina
Men wanting to father children are being advised to consider adding walnuts to their diet regularly.
Research shows that consuming just 2.5 ounces of walnuts per day – just over half a cup -for a period of 12 weeks, improves male fertility.
The study – part funded by the California Walnut Commission – worked with 117 men between the ages of 21 and 35. All of them ate a typical Western diet.
Half of them were asked to eat 2.5 ounces of walnuts per day, along with their usual diet. The others were asked to continue eating as normal, but to the exclusion of any tree nuts.
Walnuts have appreciable levels of omega-3 nutty acids, which have been linked to better levels of male fertility. Usually the improvements are linked to greater consumption of fish oil supplements.
In the study most of the walnut eating part of the group ate shelled whole nuts. A few of them ate them mixed in other foods, such as sauces and meats.
Before and after the experiment the men’s fertility was checked by researchers who were not aware of who had and who hadn’t, eaten the nuts.
At the end of the 12 week period the fertility levels of those who had eaten walnuts could be seen to have improved.
