Organic food shock: no better than non-organic

Filed under: Environment, Food, Science, Wine — Nicholas @ 07:59

This is another one of those “someone paid money to conduct the study?” studies. Organic food has been a boon to certain producers, but it doesn’t provide the kind of benefits most purchasers expect:

But organic is certainly more expensive. A new study in the American Journal of Clinical Nutrition finds:

On the basis of a systematic review of studies of satisfactory quality, there is no evidence of a difference in nutrient quality between organically and conventionally produced foodstuffs. The small differences in nutrient content detected are biologically plausible and mostly relate to differences in production methods.

The study was commissioned by Britain’s Food Standards Agency.

I’ve been skeptical about the claims for “organic” products for quite some time. Similarly, I’m not convinced that there’s any great value in the “biodynamic” model for wine. My strong suspicion is that the same general quality of wine would be produced without all the new age woo-woo mystic crap, because the vineyard owner or manager is paying closer attention to the vines. That, IMO, is the key.

When the data doesn’t support your claims, obscure it!

Ronald Bailey looks at the too-good-to-be-true claims made for caloric reduction as a life-extending tool:

Last week, two research teams reported to great fanfare that restricting the calories consumed by rhesus monkeys had extended their lifespans. Calorie restriction is thought to increase longevity by boosting DNA repair. The idea is that the mechanism evolved so that creatures on the verge of starvarion could live long enough to reproduce when food becomes plentiful again. But did the experiments really show the CR works?

In my earlier blogpost on the research results, I noted that some experts quoted in the New York Times were not convinced. Why? Because the difference in actual death rates between the dieting monkeys and the free feeding monkeys was not statistically significant.

This doesn’t necessarily derail the notion that calorie restriction may be associated with increased lifespan, but the way this study was performed does not appear to prove anything due to rigging of the data.
