Milk allergy is distinct from lactose intolerance, which is a nonallergic food sensitivity caused by the lack of the enzyme lactase in the small intestines to break lactose down into glucose and galactose. The unabsorbed lactose reaches the large intestine, where resident bacteria use it for fuel, releasing hydrogen, carbon dioxide and methane ...
Is it a food allergy, sensitivity or intolerance? Here's how to tell, according to experts.
Frequency. ~6% (developed world) [1] [2] A food allergy is an abnormal immune response to food. The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure. This typically occurs within minutes to several hours of ...
Lactose intolerance is not an allergy, because it is not an immune response, but rather a sensitivity to dairy caused by a deficiency of lactase enzyme. Milk allergy , occurring in about 2% of the population, is a separate condition, with distinct symptoms that occur when the presence of milk proteins trigger an immune reaction.
Some studies suggest that dairy foods like milk, cheese, and yogurt may actually lower your risk of bodily inflammation. All dairy products are not equal, though, says Scott Keatley, R.D., co ...
Allergies, also known as allergic diseases, are various conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. [11] These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. [1]
Types of allergens. Allergens can be found in a variety of sources, such as dust mite excretion, pollen, pet dander, or even royal jelly. [2] Food allergies are not as common as food sensitivity, but some foods such as peanuts (a legume ), nuts, seafood and shellfish are the cause of serious allergies in many people.
Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances and food allergies.

Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies, such as insect bites, and asthma. [1] [2] Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response.
