Non-suitable food for sinusitis

Food allergies

a glass of milk
Milk can worsen the symptoms of sinusitis

Among foods unsuitable for the diet of sinusitis we include those producing allergies.

The most common ones, as we have seen above, use to be those containing lactose which is present in milk and its derivatives (butter, cheese, yoghourts, custards, etc)

We could also doubt of gluten containing foods (grains or derivatives from grains) or foods containing certain preservatives and pigments as possible food producing allergies.

The best method to discover which food is not tolerated is to dispense with products of one of these groups for some days. By doing so, we will try to figure out which one of then could be the cause of sinusitis.

For example, if after having removed milk and its derivatives for a few days, we feel the same, we could say that this type of food was well tolerated and milk is not the food which is actually causing the problem.

On the contrary, if we feel better, we could point out milk as the probable reason for our sinusitis. In this case, it will be better for us to remove it from our diet an search for a substitute food.

The following chard shows a list of foods that are reported to cause most food allergic reactions. People suffering this disease should be cautions using them and should test his personal reaction for each one of them.

Main food producing allergic reactions(They produce 90 % of allergic reactions)
Crustacean shellfish (crabs, oysters, lobsters, mussels, shrimp, etc)Eggs


Milk (Cow) and derivatives (Cheese, yoghourt)

Nuts(almonds, walnuts, pecans,, etc)


Soy beans and its derivatives

Wheat and its derivatives

Many sinusitis have an origin in food allergy. Milk and milk products (cheese, yogurt, cottage cheese, custard, etc) are sometimes responsible for inflammation of the sinuses. It is important to know about those foods that can serve as an alternative to animal milk.

Are soy milk or cereals suitable for sinusitis?

Soy milk and other soy products like tofu or soy meat can provide the needed calcium to people who are allergic to lactose.

One should have to verify that sinusitis  is not caused by an allergy to soy or gluten to exclude soy or cereals containing gluten from the diet of these patients.
