How about adding iodine to table salt? https://en.wikipedia.org/wiki/Iodised_salt

Or pregnant women taking folic acid to prevent birth defects? https://www.canada.ca/en/public-health/services/pregnancy/fo...

Or giving vitamin d to newborns? https://www.cdc.gov/breastfeeding/breastfeeding-special-circ...

Should these practices be stopped because they aren't "natural"? Are breast fed babies not "eating correctly"?
