I remember reading an article here (probably posted by Demi) that I can't find again.

It stated something to the effect that when you are in ketosis (not just low carb) Gamma T cells are activated in your mucous membranes.

When you are not in ketosis they are suppressed.

If I remember correctly, these Gamma T cells protected us from viral attacks. If so, could it be a preventive for COVID-19?

Or am I remembering incorrectly and was it bacterial protection instead of viral protection?

If anyone knows, please chime in.

I do know that only time I caught a cold in the last 15 years was when I went off-plan in Vienna for one week (they are famous for desserts) and caught a bug on the airplane home. One day of runny nose, one day of a cough and then I was back to normal.

Thanks.
