Dr Alex Richardson, founder of Food and Behaviour (FAB) research, offered insights into the potential “trial and error” problems of nutrition-based studies this month, in two mainstream press articles.
“There is increasing evidence for the importance of the gut-brain axis”, she commented. “The use of probiotics and prebiotics to improve some mental health conditions is a very promising area.
“But mainstream acceptance of nutritional interventions at the level of public health recommendations relies heavily on evidence from randomised, controlled clinical trials. The provision of this kind of evidence for nutritional interventions is seriously limited…”
Dr Richardson, along with The Mother and Child Foundation’s Professor Michael Crawford, also spoke to the Mail Online about fish oil supplements and the trials supporting or debunking claims for the efficacy of omega-3 fatty acids. As Dr Richardson very vividly phrases it:
“The problem with meta-analyses is that you can only work with the evidence you have, so if you put garbage in, you get garbage out”.
