Preservatives in food can have various impacts on health. While they are used to enhance shelf life and prevent spoilage, certain preservatives, like sodium nitrite and sulfites, may pose health risks. Long-term consumption has been associated with adverse effects, including allergic reactions and potential links to cancer. Moreover, some preservatives may interfere with gut health by altering microbiota. It's essential to be mindful of these additives and opt for fresher, less processed options whenever possible to minimize risks.
