What serious diseases can artificial chemical preservatives cause?

''The consumption of several artificial preservatives, such as nitrates, benzoates, sulfites, sorbates, parabens, and formaldehyde, can lead to serious health hazards such as hypersensitivity, allergy, asthma, hyperactivity, neurological damage, and cancer. So, the health problems related to chemical food preservatives will drive the demand for organic food preservatives in the coming years.'' [1]

''Sulfites are common preservatives used in various fruits, may have side effects in form of headaches, palpitations, allergies, andeven cancer.
Nitrates and Nitrites: These additives are used as curing agents in meat products.it gets converted into nitrous acid when consumed and is suspected of causing stomach cancer
Benzoates are used in foods as antimicrobial preservatives, and have been suspected to cause allergies, asthma and skin rashes.
Sorbates/sorbic acid are added to foods as antimicrobial preservatives. Reactions to sorbates are rare, but have included reports of urticaria and contact dermatitis. ''[2]

Chemical preservatives are killing slowly causing all sorts of diseases

3. Effects of Preservatives and Emulsifiers on the Gut Microbiome By: Angel Kaufman Spring 2021 A thesis submitted in partial fulfillment of the requirements for a baccalaureate degree in Biology in cursu honorum Reviewed and approved by Dr. Jill Callahan Professor, Biology 

The human gut microbiome is more important to health than most people realize. It is filled with trillions of microbes ranging from fungi to bacteria, and viruses. This paper focuses on preservatives and emulsifiers and the effects they have on the gut microbiome. These two food additives affect different types of bacteria differently. Emulsifiers and preservatives increased bacteria that tend to have negative effects on the body while decreasing beneficial bacteria. This can have many different effects on the body from Crohn’s disease to dysbiosis and even increase antimicrobial resistance in bacteria. This review looks to explain why preservatives and emulsifiers have such negative effects, why it is such a relevant and important topic, and alternatives to preservatives or emuslisers or ways to mitigate the effect of these two food additives.
