Does high carbohydrate diet cause cataracts?

"Carbohydrate intake and glycemic index in relation to the odds of
early cortical and nuclear lens opacities"


Results: After multivariate adjustment, the odds of cortical opacities (LOCSIII ">=" 1.0) among women in the highest tertile of carbohydrate intake (">=" 200 g/d) was 2.46 times (95% CI: 1.30, 4.64; P for trend = 0.005) that among women in the lowest tertile ( "<"185 g/d).

Thanks for the interesting article and link. It would have been interesting to see if fasting glucose levels correlated as well. Presumably blood glucose tracks carb intake, but it could depend on activity level and insulin sensitivity as well. It seems like an obvious correlation to look for to support their conclusions.

Hi Cynthia and David,

Yes but it could also be caused by other factors common to most high carbohydrate diets. For example the lack of animal fat, too much hydrogenated fat, excessive omega-6 oil, fructose leakage into bloodstream or some vitamin deficiency (D3,K2,A,B12) not infrequent among such diets.

When I used to follow a high carbohydrate near-vegetarian diet (with chicken or fish once a week, no butter), I developed some strange dry eyes problem, flaring up (inflamed and slight scratches on cornea) every few months through 1992-1999. It all disappeared completely, never to reoccur again, after I switched to a high animal fat low carb diet in 1999.

Different subject: did you also find it strange that none of the usual dietary factors seems to explain/fit to the rapid rise in MI in the UK after 1914? What do you think about it (see the recent discussion on Stephan's blog)

There is very little doubts now that excessive glucose and insulin are one of the major culprits, the only problem is that they are not the only ones. You may find those papers interesting:

"Systemic Correlates of Angiographic Coronary Artery Disease" by José Pedro L. Nunes, João Carlos Silvaand

Thanks for the other articles. It seems that people are just ignoring information that has been out there and recognized by some researchers at least for a long time. Science has dogmas too, and if you don't conform, you don't get funded or published. So you'd better parrot the powerful guy's party line. It's what drove me out of academia!


Stan (Heretic) said...

Me too. I was in space research, plasma physics. You had to come up with the incremental proposals, nothing too far out or they would ignore it. What really shot my confidence in the academics, in 1989, was their treatment of cold fusion!

BTW, Stout's papers are also very interesting. I just realize that my ISP just nuked my private website by probably giving my user ID to someone else by mistake. I managed to evacuate most of the material out to my business web sites, it is now here:

R.W.Stout, The Lancet, 1968 and 1969

And the pdf's are here (courtesy Dr.Harris):

It reminded me of another event that really put me off the institutionalized "reasearch". I worked for the Phobos II Mars mission project (ESA+Soviets), and they ended up keeping all the most interesting material (photographs) away from us! Pretending that the data wasn't there, which I found later was a lie! They did exist and I found that out months later through some fringe sources. Sorry for a digression, once I start on this subject.... 8-:)
