And here is one for the guys! The addition of 75g of walnuts to the diet of healthy men improved sperm morphology, motility and vitality.
In a recent randomised trial, published online August 15, 2012. conducted by the University of California, the inclusion of walnuts in the diet of men significantly improved both sperm parameters and serum omega-3 and 6 fatty acid levels. In addition, sex chromosome abnormalities were significantly lower in the walnut group.
While this study does not clarify whether similar effects would be applicable to those with fertility issues, it would be safe to assume that adding walnuts to the diet of men planning a pregnancy may also be beneficial for a subset of males with infertility concerns.
Walnuts for the boys: Healthy snack food
Walnuts contain plenty of high-quality protein, vitamins (C&E), minerals (iron & calcium), dietary fibre and high levels of antioxidants. They are an excellent snack food, containing healthful polyunsaturated and monosaturated fats, which help to create fullness that stops overeating.
