I found this Towards an Optimal Diet at [https://erictopol.substack.com] to be a very worthwhile read on the science of eating well. it is a difficult ‘area’ to study and it is full of snake oil peddlers, Stay away from stuff you can’t find at home. eat more protein as you grow older. and, if you’ve got issues with weight, try time restricted eating.
