Crap makes you depressed?


The BBC reported this the other day

Here is the study

Dietary pattern and depressive symptoms in middle age.

BACKGROUND: Studies of diet and depression have focused primarily on individual nutrients. AIMS: To examine the association between dietary patterns and depression using an overall diet approach. METHOD: Analyses were carried on data from 3486 participants (26.2% women, mean age 55.6 years) from the Whitehall II prospective cohort, in which two dietary patterns were identified: 'whole food' (heavily loaded by vegetables, fruits and fish) and 'processed food' (heavily loaded by sweetened desserts, fried food, processed meat, refined grains and high-fat dairy products). Self-reported depression was assessed 5 years later using the Center for Epidemiologic Studies - Depression (CES-D) scale. RESULTS: After adjusting for potential confounders, participants in the highest tertile of the whole food pattern had lower odds of CES-D depression (OR = 0.74, 95% CI 0.56-0.99) than those in the lowest tertile. In contrast, high consumption of processed food was associated with an increased odds of CES-D depression (OR = 1.58, 95% CI 1.11-2.23). CONCLUSIONS: In middle-aged participants, a processed food dietary pattern is a risk factor for CES-D depression 5 years later, whereas a whole food pattern is protective.

I am not sure that I'd class full fat dairy as processed crap though. Especially in the light of news like this:

Children who often drink full-fat milk weigh less

Eight-year-old children who drink full-fat milk every day have a lower BMI than those who seldom drink milk. This is not the case for children who often drink medium-fat or low-fat milk. This is one conclusion of a thesis presented at the Sahlgrenska Academy at the University of Gothenburg, Sweden.

The study showed that children who drink full-fat milk every day weigh on average just over 4 kg less.
