Overly processed or packaged foods typically have added sugars, salt, preservatives, and high levels of fat, which aren’t the best for you or your lymphatic system. According to Lifetimevibe, eating too many processed foods like chips, breakfast cereals, and packaged lunch meats can lead to inflammation and fluid retention, which can impair your body’s lymphatic function.

Red meat

Red meats like beef, pork, lamb, and veal can cause lymphatic problems due to the possible hormones given to the animals, per WellSquad. Having too many red meats in your diet can also lead to inflammation and upset your gut microbiome, reports Livestrong.

Caffeinated drinks like coffee are diuretics, which means they dehydrate your body. They can dilate the lymph tissue and cause blockages in the lymphatic systems, per Cure Today.


Alcohol has the same effect on your lymphatic system as caffeine, because both are dehydrating. According to Lifetimevibe, drinking too much alcohol can lead to inflammation, fluid retention, and problems with your body’s lymphatic function.

Salt can cause your body to retain water, which can cause problems for people who already have lymphedema. Excess salt intake can lead to swelling.


Added sugars in the food you eat are also not good for your lymphatic system. It contributes to inflammation, fluid retention, and impaired lymphatic function, per Lifetimevibe. To avoid consuming too much sugar, make sure to read food labels. Many processed foods like spaghetti sauce or bottled salad dressings contain unnecessary sugar.
