More biased research on the wonders of walnuts

url

The California Walnut Board’s been busy lately. The latest study funded by them, to be published in the June issue of The Journal of Nutrition, found that consumption of whole walnuts and walnut oil had a positive effect on blood vessel function following a meal as well as improving the effectiveness of HDL (the “good” cholesterol). This is all lovely but I have a few questions.

I wonder how walnuts and walnut oil fare in comparison to other nuts and oils. I also wonder if there are any long-term implications for these findings. A short-term effect of consumption of a food, both positive and negative, means little in the big picture. Sure, it may very well be true that consumption of walnuts improves cardiovascular health but such a small study (only 15 participants) over such a short period of time: 30 minutes, one hour, two hours, four hours and six hours after administration of treatments really doesn’t tell us much about the impact of walnut consumption on long-term health.

I complain about unscientific practices a lot but science like this is just as bad. Give me a large, long-term, double-blind, study with unbiased researchers and then we can talk about the miracles of walnuts.

Blind faith versus science

What’s up with the hating on science lately? I’ve been noticing a number of people talking about science with disdain and it’s really getting under my skin. It’s as if there’s something superior about subscribing to unfounded treatments. And wanting scientific proof of the efficacy of a treatment is a lack of faith. When did healthcare become a religion? Why would someone say, “Oh, dietitians follow science” with a tone as if we’re a bunch of unenlightened atheists while they follow the true word of their holistic god. I’m open to new developments and if you can prove to me that there is some benefit (beyond a placebo, although admittedly placebos can be pretty powerful) to consuming whatever extract or supplement you’re extolling the virtues of then I’ll gladly change my tune. But is it really so wrong of me to want proof? Why should I blindly throw my money and support behind unproven remedies? And why can’t this dialogue go both ways? I watched those Food Matters documentaries. I want to hear all sides of a story. It baffles and frustrates me that so many people buy into this sort of thing. Not only without bothering to check out the validity of claims being made but wantonly ignoring evidence that goes against their viewpoints. I’m sorry but there is nothing virtuous about putting blind faith in unproven remedies and spurning science.
