Post-nasal drip is an uncomfortable condition that most people will experience at some point. It involves the gathering of mucus at the back of the throat, making for constant swallowing and throat-clearing. There are certain foods that make this problem worse, so if you notice this condition plagues you often, try cutting out these foods.


Though it’s never been definitively proven, many doctors say patients often report that cutting out dairy helped their post-nasal drip tremendously. It’s been a piece of conventional wisdom for decades, too, that milk makes you phlegmy. If you tend to drink a lot of milk or eat a lot of ice cream, it’s definitely worth cutting down to see if it helps.

Greasy Foods

Foods that are heavy in oil or grease, like fried foods or pizza, are also said to cause the body to produce mucus much like milk. Additionally, these foods can cause an upset stomach, which may lead to acid reflux and further throat discomfort.


Finally, the most common cause of post-nasal drip is allergies. So stop eating foods you’re allergic to! That may sound obvious, but many people learn from allergy tests that they are allergic to certain foods to which they have no reaction. It’s also common for certain foods like eggplant or pineapple to give people a tingly or fuzzy tongue, without them realizing it’s an allergic reaction. If you’ve done one of these tests or feel the tingle and continue to eat certain foods anyway, cutting them out could help your post-nasal drip.
