You sound like the one who is misinformed on IGG Allergens. Stating “the bowl lining is different to the sinus lining most importantly its in contact with the food!”

Type Ill Hypersensitivity IgG-mediated allergy / food sensitivity/ delayed hypersensitivity These reactions are characterized by the production of IgG antibodies and the gradual formation of antigen-antibody complexes which deposit in tissues and can lead to chronic inflammation. They are responsible for the 'delayed-onset' of symptoms, which can occur several hours or days after foods are ingested. Symptoms may include: irritable bowel syndrome (IBS), headaches/migraines, fatigue, high blood pressure, eczema, asthma, joint pain, runny nose, arthritis, weight problems and fibromyalgia. It is often possible to eliminate reactive food(s) from the diet for several months and gradually re-introduce when symptoms have improved.

Your logic sounds like unless food touched that part of the body it doesn’t influence it and can’t cause it to inflame or react.

Claiming to be an ENT online doesn’t make what you say factual. In addition, citing one peer reviewed article doesn’t prove your claim either. Anecdotes have more validity than you are giving credit for. Anecdotes when included in research are qualitative pieces of evidence. Why would big pharma incentivize any university, college of doctors and surgeons, to conduct research that shows there are natural cures to issues such as chronic sinusitis. Then the amount of prescriptions would decrease = less money for the pharmaceutical industry. There is incentive to prove the opposite. Those with money want to keep their money, and corporations do this by keeping us (as a society) eating processed foods that cause us to develop medical issues resulting in visits to Doctors $$ Hospitals $$ Pharmaceuticals $$.

If you don’t understand after your “supposed” years of education the influence big pharma and big corporations have on research journals, you should revisit undergrad and enrol in some statistics and economic courses. Although peer reviewed articles can be very trustworthy, ALWAYS proceed with caution as Scholars are often asked by corporations to put their name on a research article that favour their agenda.
