Again...no judgement what so ever. Throwing my two cents out there, and appreciate everyone else's two cents. (Wish you hadn't deleted yours, Fluffy!)
Ideas on nutrition have changed many times over...and I expect they'll continue to.
Bottom line...do what works for you. What you feel safest doing. What you feel healthiest doing.
As down as I personally am on keto...there are some really interesting studies involving kids with seizures and autism being helped by keto diet. They know it improves some neurological disorders, they don't know exactly why. I think we're going to learn a great deal about a lot of illnesses with further research into the gut microbiome....which is in it's infancy.
Also....older adults do better on higher protein diets....as contradictory as this seems.
So, there's a lot of wiggle room for new information and new ideas that might take us in different directions.
I respect everyone's choices.
