Posted 27 January 2014

Readers will be aware that some while ago, Solal made claims in adverts that Vitamin D is effective for colds/influenza. We pointed out that the claims were false, and the data from the study they used (Japanese schoolgirls), misconstrued.

Two studies published, one at the end of 2013, where Vitamin D/D3 was tested to see if it would work in preventing influenza/colds, found that they did not. Will Solal change their claims? Unlikely, selling Vitamin D and making money is more important.

Regulating that mess would be tedious, the kind of project enjoyed by the EU. Enter Nutrition and Health Claims Regulation in 2006.Since then member states have submitted thousands of health claims for manufacturers about cranberries, fish oil and every magical ingredient you can think of. This week it turned out that 900 have been examined so far, of which 80% have been rejected.”

Omega-3 lesson: Not so much brain boost as fishy research

Continue Reading 3

One tiny brain-imaging study of fatty acids has been used to endorse fish oil as education’s magic pill. Oddly enough, someone has now finally conducted a proper trial of fish oil pills, in mainstream children, to see if they work: a well-conducted, randomised, double-blind, placebo-controlled trial, in 450 children aged 8–10 years from a mainstream school population.
