food sensitivity is somehow between allergy and intolerance, as it dose not involve IgE mediated immune response but IgA and IgG ,sometimes called cell mediated immune response or non-IgE allergy and considered type of allergy,, its difficult to separate between then though

1. FOOD SENSITIVITY

2. Food sensitivities
• — also known as delayed hypersensitivity reactions because
they occur within hours to days of exposure — are
sometimes categorized as a subset of food allergies. After all,
they involve the immune system as well.

3. Food Sensitivity
• Does not typically activate the immune system, but
produces antibodies like IgA and IgG
• Food sensitivities are cell-mediated, not IgE-mediated.
• Reactions can be delayed, but no risk for anaphylaxis
• Can exacerbate inflammation in the body
• Common symptoms: digestive issues, fatigue, headaches,
skin rashes like eczema or dermatitis

5. Food Sensitivity Symptoms
• Do you suffer from any of the
following symptoms? A food
sensitivity may be to blame.
1. Acne
2. Brain fog
3. Eczema
4. Dry and itchy skin
5. Bloated stomach after eating
6. Fatigue
7. Joint pain
8. Reflux
9. Migraines
10. Diarrhea
11. Depression and mood swings
12. Runny nose
13. Headache
14. Trouble sleeping
15. Dark circles under eyes

6. Types of Hypersensitivity Reactions
• The response of the host to the
presence of foreign substances
can trigger four types of
hypersensitivity reactions:
• Immediate
• Cytotoxic
• Immune complex
• Cell-mediated

7. Is there a test for it?
• blood tests can be run for food sensitivities using IgA, IgG,
and other antibodies. These tests can help you quickly
identify foods that may be causing symptoms, but should
not be used as diagnostic tools. Keep in mind these test
results can be unreliable and can change.
