Ciekawostka: More people are allergic to cow's milk than any other food

Evidence: 100 • authority: 72

Milk allergy is an adverse immune reaction to one or more proteins in cow's milk. Symptoms may take hours to days to manifest, with symptoms including atopic dermatitis, inflammation of the esophagus, enteropathy involving the small intestine and proctocolitis involving the rectum and colon. However, rapid anaphylaxis is possible, a potentially life-threatening condition that requires treatment with epinephrine, among other measures. In the United States, 90% of allergic responses to foods are caused by eight foods, including cow's milk. Recognition that a small number of foods are responsible for the majority of food allergies has led to requirements to prominently list these common allerg…

Food allergy in the Saudi population: trends, triggers, and strategies for care - a systematic review.. Food allergy is a common clinical problem in Saudi Arabia with multiple factors contributing to it including the changes in lifestyle, especially among the younger generation. This systematic review presents evidence regarding the epidemiology, etiology, and management of allergic diseases in the Kingdom. This systematic review with narrative synthesis was conducted following PRISMA 2020 guidelines. Due to substantial heterogeneity in study design, diagnostic approaches, and outcome measures, findings were synthesized narratively according to evidence type and research focus., The review…

This is a list of allergies, which includes the allergen, potential reactions, and a brief description of the cause where applicable. An allergy is a misguided type-I hypersensitivity response triggered by binding of an allergen to immunoglobulin E (IgE) antibodies. Antibody reactions require a molecule of sufficient size. As a result, most allergens are large biomolecules such as proteins and carbohydrates, many of which can be removed or broken down by food processing. A smaller molecule may still become allergenic by binding to a larger molecule to form an epitope of sufficient size; such a small molecule is called a hapten. This list also includes some other forms of hypersensitivity re…

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 exposure. When the symptoms are severe, it is known as anaphylaxis. A food intolerance and food poisoning are separate conditions, not due to an immune response. Common foods involved include cow's milk, peanuts, eggs, shellfish, fish, tree nuts, soy, wheat, and sesame. The common allergies vary depending on the country. Risk factors include a family history of allergies, vitamin D deficiency,…

Allergen-specific IgE sensitization spectrum in 4,166 children with allergic diseases at a county-level hospital in eastern China: a retrospective cross-sectional study.. Objective This study aimed to characterize the serum specific IgE sensitization spectrum in children with allergic diseases at a county-level tertiary hospital and to evaluate age-, sex-, and co-sensitization patterns. Methods This single-center retrospective cross-sectional study included 4,166 children aged χ 2 /Fisher's exact tests and multivariable logistic regression, and co-sensitization was evaluated using the φ coefficient. Results The overall sensitization rate was 75.85%, with higher positivity in boys than girls…

The Potential Link Between Eosinophilic Esophagitis and Food Allergy: Inflammatory Pathogenesis and Management.. Eosinophilic esophagitis (EoE) has transitioned from an isolated gastrointestinal disorder to a recognized type 2 immune-mediated allergic disease, most likely representing a late manifestation of the atopic march. This comprehensive review examines the complex inflammatory pathogenesis linking EoE and food allergy, and critically discusses the mechanisms of disease induction, dietary treatments, and emerging clinical challenges. While genome-wide association studies identify shared susceptibility loci with classic atopy, EoE exhibits distinct tissue-specific pathways, particular…

Milk Allergies and Other Food Allergies in Children

Evidence: 53 • authority: 72

Milk is usually a white liquid food (but can be shades of yellow, cream, pink, or brown) produced by the mammary glands of lactating mammals. It is the primary source of nutrition for young mammals before they are able to digest solid food. Milk contains many nutrients, including calcium and protein, as well as lactose and saturated fat; the enzyme lactase is needed to break down lactose. Immune factors and immune-modulating components in milk contribute to milk immunity. The first milk, which is called colostrum, contains antibodies and immune-modulating components that strengthen the immune system against many diseases. As an agricultural product, milk is collected from farm animals, most…

A2 milk is a variety of cows' milk that predominantly contains the A2 form of β-casein proteins (as opposed to A1 milk, which contains mostly A1 β-casein proteins). Cows' milk like this was brought to market by The a2 Milk Company and is sold mostly in Australia, New Zealand, China, and the United States. It was sold in the United Kingdom between 2012 and 2019. Non-cow milk, including that of humans, sheep, goats, donkeys, yaks, camels, buffalo, and others, also contains mostly A2 β-casein, and so the term "A2 milk" is also used in that context. The a2 Milk Company and some companies producing goat's milk products claim that milk containing A1 proteins is harmful, but there has been no wide…
