Calcium-rich Foods.
When I found out last year that I am lactose intolerant my immediate thought (after hell no, no more Manchego?!) was 'but what about calcium?'.
Dairy is one of the most talked about food groups when it comes to reproductive health.
The Nurses Health Study II began in 1989, tracking thousands of female nurses and their health over an 8 year period. The research found low-fat dairy to be associated with a greater risk of ovulatory infertility and by contrast, 'greater intake of high-fat dairy food was associated with a lower risk anovulatory infertility'.
What the heck is anovulatory infertility? It's when you don't ovulate in a cycle, so no egg is released from the ovaries and therefore cannot be fertilised by sperm.
Some schools of thought are looking into whether it was likely the fat and calcium in dairy that was potentially boosting of fertility and not just the dairy itself. So, if you're not a dairy consumer then where do you get your calcium? Turns out there are plenty of other ways to get calcium into your daily meals. Here are just a few of them...
Almonds
Tahini (my current favourite!)
Broccoli
Dark Leafy greens (such as collard greens and kale)
Bok choy
Beans
Tinned salmon/sardines with bones
Chia seeds
Lentils
