Nutrition
Just because a claim about a nutrition intervention is made by an expert or authority, you cannot be sure that it is trustworthy.
Just like everyone else, doctors, researchers, and patients often disagree about the effects of interventions. This may be because what they say is not based on a systematic review of fair comparisons of interventions.
People should not decide how trustworthy a claim about a nutrition intervention is based only on who made the claim or how experienced, well known, or “expert” they are; or where the claim was made. Claims that are not based on fair comparisons of interventions can be found in sources that are well-respected, as well as ones that are not.
BEWARE of claims about nutrition interventions like “recommended by nutrition experts” or “doctors say”.
REMEMBER: Just because a claim about a nutrition intervention is made by an expert or authority, or comes from a well-respected source, you cannot be sure that it is trustworthy, unless it is clearly based on a systematic review of fair comparisons of interventions.
