NYT Health Reporting Grab-Bag

Yet another reason to avoid flip flops: they can cause foot pain. And sorry to break this to you, but your toes are basically ugly.

People over-report their consumption of fruits and veg on a survey when they have previously received a letter in the mail extolling the benefits of such foods along with a set of 5-a-day schwag. Neither the blog post nor the article abstract clarify how a demonstration of researchers' use of unorthodox and obviously biasing survey methodology to influence respondents to over-report fruit and veg intake compared to a control group can support the claim: "But when it comes to fruits and vegetables, it appears people lie in the other direction — vowing that they consume far more than they really do." It is, as far as I know, a well-known and established fact that it is easy to manipulate respondents by using this kind of methodology, and various kinds of demand characteristics are regularly studied. The question is whether the bias extends to research using the standard, "neutral" methodology for food recall regularly used by health scientists.

And in shocking news, "Many normal weight teens feel fat." Also, rain is wet.

Beyond the fact that we're all saying "duh"... how do they back this theory up? -- "The data suggest that efforts to address unhealthy weight gain and obesity among young people have the the potential for “collateral” damage in normal-weight kids, who may develop self-esteem problems". It's like well, we have to choose between an obesity epidemic and self-esteem issues, hmmm. Besides, they may be of normal weight, but are they actually active and physically fit?
