Too good to be true

“100% certain!”

We can rarely, if ever, be 100% certain about the effects of nutrition interventions.

Fair comparisons of interventions provide the best basis for being confident about the effects of nutrition interventions. However, it is rarely, if ever, possible to be 100% certain about the size of intervention effects, or to know exactly what will happen if a nutrition intervention is used.

BEWARE when someone suggests that it is 100% certain that a food, drink, diet or nutrition supplement works or is safe.

REMEMBER: There is some uncertainty about the effects of nearly all nutrition interventions.
