Lots of media coverage on a new study today, which is apparently going to compare the reported offences of prisoners while taking either placebo or a fish oil+multivitamin+mineral supplement. Some headlines have interpreted this as ’Prison study to investigate link between junk food and violence’. I think that’s an extrapolation too far; the quality of the food the people eat isn’t going to vary during the study (although nourishing food, and the social interactions of eating should perhaps be an area of further interest in this group of people.)
The apparent health improving qualities of fish oils have been much overhyped in recent years. However there have been previous studies done looking at the effects of fish oils in prisoners and good quality evidence on a larger scale is to be welcomed. I haven’t seen the trial protocol on the register yet, but will keep an eye on this story.
