Weird Dietary Science

The Telegraph (U.K.) reports research results from Australia, with an interesting and counterintuitive finding. Professor Felice Jacka, who led the research at Deakin University, Victoria, is quoted as saying:
We had originally thought that red meat might not be good for mental health but it turns out that it actually may be quite important.

When we looked at women consuming less than the recommended amount of red meat in our study, we found that they were twice as likely to have a diagnosed depressive or anxiety disorder as those consuming the recommended amount.

Even when we took into account the overall healthiness of the women's diets, as well as other factors such as their socioeconomic status, physical activity levels, smoking, weight and age, the relationship between low red meat intake and mental health remained.
I'd urge caution in interpreting these findings. While diet may influence mood, as the article seems to suggest, it is also possible that mood influences diet. It's a chicken and egg problem.

Depressed women may avoid red meat because their depression makes them more anxious about their health. Red meat has a (mostly unearned) bad reputation among the health conscious. Hat tip to Instapundit Glenn Reynolds for the link.
