Could RDIs be based on genotypes in the future?
So fast forward 20 years and could RDIs for certain nutrients be based on genotype?
Maybe, said Dr El-Sohemy, but it won’t just depend on the science, but on economic, social and ethical factors (who is collecting the data, who has access to it, is it actionable, are the tests affordable etc etc).
“There’s no point making dietary recommendations based on your genotype if you don’t know what your genotype is.”
