What they’ve said....and I’ve read through their piece and additional studies....is that if you just ate a balanced diet...you’d get all the vitamins necessary. The ability of vitamins to translate over for ‘lost vitamins’ because you won’t eat a balanced diet? Marginal. It’s not working the way that everyone was convinced over the past forty years.
At the end of this whole mess, one needs to ask themselves where exactly they went off the road for eating a balanced diet. We used to be a society that took simple raw ingredients and made entire dinners from that...without processed sugar, great amounts of sodium, or high fat contents.
The processed sugars yes because it was not available the rest they added as much as they could. Salt is very very necessary especially if you are doing physical labor. We went to great lengths to get it.
Fat give you the calories needed to keep going, allows your body to use the protein in the rest of the food, keeps your nervous system healthy and keeps your skin from drying out.
It was not usual for people to come out of winter with various physical ailments because of a lack of a balanced diet and the poor who ate dinners made of "simple raw ingredients" were often sick and died young.
