Eating Nuts Improves Your Fertility - According To A New Study
Know anyone trying for a baby?
Know anyone trying for a little bundle of joy, or been trying to conceive yourself?
Move over red roses! You might be interested to know about a new piece of research which claims that simply eating nuts like almonds (and other tree nuts) boosts sperm quality to help couples facing challenges in having a baby.
The humble nut may help to support male fertility with researchers finding that eating just 60 grams (about two moderate portions) of nuts daily significantly improves the total sperm count and the vitality, motility and morphology (size and shape) of the sperm.
This recent study – with a combination of almonds (15g), hazelnuts (15g) and walnuts (30g) increased sperm count by 16%. So, it seems that a mix of nuts may be key. And, almonds are rich in zinc, which contributes to normal fertility and reproduction.
Previous research on infertility has suggested that poor eating habits, among other unhealthy behaviours and environmental factors, may be a contributor to declining sperm counts and sperm quality in industrialised countries. The new FERTINUTS study, was first presented at the 2018 European Society for Human Reproduction and Embryology meeting.
This study builds on a previous finding on walnuts alone (75g/day for 12 weeks) that found improvements in sperm vitality, motility and morphology, but not in total sperm count.
The addition of almonds and hazelnuts to the study diet resulted in improvements in the same measures of quality, but increased sperm count as an added benefit. Great if you're trying for a baby!
Consultant Dietitian Juliette Kellow says:
“Having a healthy diet is an important, but often-overlooked piece of the fertility puzzle. This study shows that adding tree nuts like almonds offers a potentially easy way to boost male fertility and may help support couples trying to conceive.”
In a 14-week trial, those who ate more nuts generally saw the following results...
- 16% higher sperm count
- 6% improvement in sperm motility (sperm cells’ ability to swim)
- 4% higher sperm vitality (the amount of live, healthy sperm cells found in semen)
- 1% improvement in sperm morphology (which refers to the sperm cells’ normal healthy size and shape)
Importantly, those in the nut-eating group also had less sperm DNA fragmentation, showing that genetic integrity was better preserved in the sperm of nut-eaters. (When sperm DNA is too fragmented, fertility declines or miscarriage risk is higher.)
