Here:
I don’t think the study has stable foundations…
The participants were given questionaires for self reporting. They also knew what the study was for. Also, the control group (with the unchanged diet) were contacted fewer times than the “healthy diet” group.
The participants were undergrad students with mild anxiety and depression symptoms.
I think it’s possible their mood improved on the healthier diet beacuse they felt that someone cares about them.
Authors of the paper put in 3 fat paragraphs about the limitations of the study.
They also mention brand names for some of the foods, at the same time they do not disclose where the funding comes from. Looks like advertising for me.
So, hmmmmmmm…
