Mucous is a necessary component in the body, as it keeps the interior linings of the body moist. Mucous also is produced in response to what the body feels may be toxic invaders, such as dust particles, or even certain foods. Mucous also forms in response to irritants, and there are some foods that irritate the body into producing unhealthy mucous, which is thick, cloudy and sticky.
Dairy products are known as the most mucous-producing food there is. According to Dr. Ingrid Pincott, a naturopath, milk and dairy products increase the production of mucous, which increases the rate of respiratory illnesses and congestion. Dairy products are also highly allergenic, and can lead to intestinal distress and diarrhea, as well as stools that contain thick mucous.
Gluten Containing Products
In an excerpt from the book "North American Diet," it is explained that foods that contain gluten, such as anything with rye, wheat, oats or barley, are mucous-producing foods. Gluten is a "glue-like" substance that holds molecules together, and requires the production of extra stomach acid for digestion. Foods containing glutens are breads, pasta, baked goods and cereals. Gluten, in the form of flour, is also found in soups, sauces and even injected into some meats.
Meats are another class of mucous-forming foods. According to Janis M. Betz, R.N. in an article titled "Colon and Digestive Health" on healthyjourney.org, meat produces mucous due to the fact that it is difficult to digest. Your body needs to create sticky mucous to help digest the strongly linked proteins in meat, which are different from plant proteins.
