Fast food

Many poor health effects have been linked to fast food. Eating it too regularly may also have a negative impact on your immune system. Fast food and highly processed meals can trigger inflammation, increase gut permeability, and cause bacterial imbalance in the gut, all of which can harm your immune system. Bis(2-Ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DiNP), two forms of phthalates, can also be found in fast food. Phthalates can enter fast food through packaging or plastic gloves used during food preparation.

Phthalates are known to damage your body's endocrine system, which produces hormones. They may also induce an increase in the synthesis of inflammatory proteins, which can impair your immunological response to infections and create immune dysregulation. Furthermore, phthalates may limit gut flora variety, which might harm your immune system.
