Walnuts 'UP' sperm count. Eating walnuts may help increase sperm count in men and improve its quality, a new study has found. Scientists at the University of California asked a group of young men in their 20s and 30s to eat 75 grams of walnuts every day for three months.

The research found that men managed to increase their sperm count and its quality, potentially giving them a better chance of fathering a child, compared with a group of men who avoided walnuts.

Researchers chose walnuts because they are a major source of “good” polyunsaturated fats, the Daily Mail reported.

Walnuts are rich in omega 3 and omega 6 — also found in oily fish — which are thought to be good for sperm development and function but are lacking in many Western diets. One in six couples struggle to conceive, and it is thought around 40 per cent of these problems are due to problems with the man’s sperm. Go here for more.
