A new study found that consuming a handful of walnuts a day could boost male fertility, which is a major problem across the world.
"The initial research we conducted regarding walnuts and male fertility found improvement in sperm parameters after adding walnuts to the diet and has set the stage for us to further explore the impacts of walnuts on male fertility and reproductive health," said professor Wendie Robbins of the UCLA School of Nursing.
"New projects are underway that we hope to be able to share with you in the near future," she said.
Infertility is defined as a "disease of the reproductive system" and results in disability. Daily consumption of 75 grams of walnuts improved sperm vitality, motility and morphology in a group of healthy young men between 21-35 years of age.
Over 70 million couples worldwide experience sub-fertility. 30% to 50% of these cases are attributed to the male partner. Walnuts are the only nut that are an excellent source of alpha-linolenic acid.
