Is KFC Kentucky Grilled Chicken Breast High in Histamine?

KFC Kentucky Grilled Chicken Breast

High histamine

This grilled breast is high because its marinade includes soy sauce, soybeans, chicken stock, and yeast extract.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

Gluten Histamine Liberator

This is a grilled chicken breast marinated with soy sauce, soybeans, chicken stock, autolyzed yeast extract, and a wheat-flour blend of spices.

Soy sauce, soybeans, and yeast extract — soy sauce is fermented and soybeans and autolyzed yeast extract are all high, and they carry the marinade well up.
Chicken stock and wheat — the added stock is also high and the wheat flour and wheat are moderate, so several parts push in the same direction.

Grilled sounds lighter, but this marinade is what lifts it, so a simpler item works better.
