Low-Fat Dairy: Risk of Infertility?
Using data from 116,000 US nurses - Harvard researchers have found that women who frequently ate low-fat dairy were 85% more likely to have ovulation problems.
However if eating full-fat dairy foods appeared to cut the risk of this type of infertility.
If the women ate two or more portions of low-fat dairy produce a week, the risk of infertility due to ovulatory failure appeared to be 85% higher.When women eating two or more portions of full-fat dairy produce such as whole milk or ice cream were compared with those eating one or fewer, they had a 27% lower risk of infertility due to lack of ovulation.
Other scientists disagree.
...other scientists say that the only compelling evidence of a link between diet and infertility involves obesity, which is linked to a significant reduction in the chances of conception.

That would be pretty cool if it turns out to be true. At least for me, ha ha! No wanted babies here, believe me!
ReplyIs this really a surprise?
ReplyEr...no babies wanted, I meant.
ReplySo the logics is people using low-fat dairy are obese? That seems like a poor excuse. In any case they need to repeat the study just with normal weight low-fat dairy female consumers.
ReplyAs someone who's trying to get pregnant, I do have to say that a small bowl of ice cream every now and then sounds awfully tempting. It did when I wasn't trying, but hey, now I have an excuse! :-D
And nobody get your undies in a twist... I'm sucessfully maintaining a 21.7 BMI, so a little bit of ice cream in an otherwise healthy diet isn't gonna kill me.
ReplyThe data is what is it - a statistically significant finding that consumption of low-fat dairy is associated with a higher risk of annovulatory infertility and an inverse association when whole dairy is consumed.
Simple as that..."logic" doesn't come into play here; the disagreement quoted above is an opinion - obesity causes infertility...yet 25-30% of women diagnosed with infertility are normal weight.
Does obesity contribute or increase risk? Sure...but there are many other things that come into play and as the researchers noted, regarding dairy foods, it may be that factors in the dairy fat are beneficial to reproductive health (effect on horomones, IGF-1, etc.) that you do not get when consuming low-fat dairy products.
ReplyI'm having a hard time with this report. Does the ovulatory failure really have to do with dairy products? - or perhaps it's just that we're not getting the healhty fats that our bodies need? I can't imagine that eating/drinking low-fat dairy has anything to do with ovulation. However, I can imagine that getting healthy fats into your diet would improve your chances of getting pregnant. This is probably just another study that's been stripped down and simplified by the media.
ReplyMary, if you read the link they have some theory as to the cause. Estrogen/Androgen amounts. I do think this study needs further study as they say, and we do like to study things. :-)
