Diana Rodgers, an author and registered dietician, is the host of the Sustainable Dish Podcast where she sometimes recounts her attempt to eat 100% of her daily values of all nutrients for a whole month, that is, consume 100% without supplements. Nearly impossible, Rodgers relied on eating liver, oysters, and other particular and sometimes expensive food sources every day to meet the demand.

Yet there are certain foods that are so rich in a particular nutrient that a mere bite can satisfy one’s daily requirements. Sometimes these foods are not advocated for by government agencies in particular, because they go against existing nationwide recommendations against eating too much meat, or fatty foods.

It bears repeating that RDAs, or recommended daily allowances, set by government agencies, have long been established at the bare minimum for survival.

Harri Hemilä, a researcher at the Department of Public Health, University of Helsinki in Finland, details that even as late as 1990, the RDA recommendations for Vitamin C were “arbitrarily set at 60 mg/day to ‘provide an adequate margin of safety’ against scurvy,” even though the Nobel Prize-winning scientist who first discovered Vitamin C advocated for a gram per day, and that there were all kinds, (and there are) of problems that can arise from low C intake before the “pre-mortal” condition of scurvy.

However, if a single bite covers the bare minimum, it isn’t outlandish to imagine a second would serve as a realistic 100% dose, and here are some of those 1-3 bite doses.
