Food is one of the most common allergens. The causes of allergies can be classified into 2 groups which are acute food allergies and chronic or latent food allergies.
It is occurs when the body cannot digest food properly which may be caused by regularly taking antibiotics, antacids, and alcohol, repetitive eating, or physical abnormalities. When the small intestine is impaired, it allows large amount of food that is not completely digested going through the intestinal wall to bloodstream. Therefore, immune system produces substances against those foreign bodies. These substances will bind nutrients that we normally take and release many chemicals. As a result, chronic inflammation or allergies can be occurred although we may have eaten that kind of food without allergic reactions.
Latent allergy with unidentified symptoms can be occurred in every system of the body. The symptoms will be different in each patient such as fatigue, excessive sleepiness, stress, migraine attack, irritability, depression, body pain, osteomyelitis, constipation with diarrhea, otitis media, stuffy nose, sinusitis, asthma, chronic shortness of breath, rash, skin inflammation, chronic acne, pyrosis, bloating, indigestion, intestinal inflammation, anemia, edema, and weight gain. These symptoms may occur so often that many people think it is normal. Patients may be treated with medication, yet the symptoms have not improved. However, it is found that these symptoms may occasionally disappear after changing the types of food. This shows that you have latent or chronic food allergies.
