foods that cause mucus buildup
Grains and nuts. All foods made from processed wheat flour create an unhealthy mucus build up in the body. Breads, pastas and processed cereals, and nuts, seeds and legumes cause mucus. In fact, cooked grains are also known to cause mucus.
Beverages, sugar and salt. Beverages like coffee (caffeine), black tea, alcohol and soft drinks are known to accelerate mucus buildup. Black tea contains the most caffeine, and it creates excess mucous. Processed foods containing salt and sugar produce mucus in the body.
Likewise, cheese, yogurt, butter, cream and other milk products are termed as mucus promoting foods because of the presence of lactose in them. Lactose leads to mucus formation, which is why milk and milk products should be avoided over here.
