Short-chain fatty acids (SCFAs), the end products of fermentation of dietary fibers by the anaerobic intestinal microbiota, have been shown to exert multiple beneficial effects on mammalian energy metabolism.

When taken up, a large part of the SCFAs is used as a source of energy. In humans, SCFAs provide ~10% of the daily caloric requirements (31).

SCFAs have been shown to increase the AMPK activity in liver and muscle tissue (17, 121, 125).

Exogenous acetate formed by colonic bacterial fermentation enters the blood compartment and is mixed with endogenous acetate released by tissues and organs (103, 104). Up to 70% of the acetate is taken up by the liver (105), where it is not only used as an energy source, but is also used as a substrate for the synthesis of cholesterol and long-chain fatty acids and as a cosubstrate for glutamine and glutamate synthesis. Other tissues including heart, adipose tissue, kidney, and muscle metabolize the remainder of acetate (104).

SCFAs seem to beneficially affect glucose metabolism by normalizing plasma glucose levels and increasing glucose handling.

Hmmm...

You'd be great at dissecting the composition of the vaccine and telling us how they're affecting people, especially children.
