                                The idea that certain foods are "mucous foods" has been around for centuries, with the 12th-century philosopher Moses Maimonides suggesting that milk can cause a "stuffing in the head". But what are mucous foods exactly, and is there any modern scientific evidence to support this claim? The concept refers to foods that are believed to increase the body's mucus production or make existing mucus thicker, leading to congestion and respiratory discomfort.
