Food Allergy Market Growth Factors

Increasing Physician-Dispensed Cosmeceuticals’ Advantages Are Boosting the Demand

A particularly concerning trend is driving the food allergy market: the rising prevalence of food allergies, especially among children. This increase in the number of cases is translating into increased demand for different solutions at all levels of the market. For instance, according to the Asthma and Allergy Foundation of America, more than 100 million people in the U.S. experience various types of allergies each year. Common examples include seasonal allergies, eczema, and food allergies. Moreover, nearly 1 in 3 U.S. adults and more than 1 in 4 U.S. children have a seasonal allergy, eczema, or food allergy. The increasing number of allergy patients contributes to the expansion of the market, in view of the need for precise diagnostic tools and early identification of allergens, while also requiring effective emergency treatment and preventive measures such as allergen-free food options.

Increased Demand for Improved Diagnostics

A key driver of the food allergy market is the demand for better diagnostic tests. Traditional methods, such as skin prick tests, which are effective, can be time-consuming and uncomfortable. The result is that innovative and effective test methods are missing. Advances such as blood tests, which offer a more convenient and potentially more accurate way of identifying food allergy, are responding to the market. In addition, there is increasing interest in the development of home testing kits that could make it easier for people to manage their allergies proactively and enable them to take more active roles.

Market Restraining Factors

High Cost of Treatments

High costs associated with different treatments are an important obstacle to the management of food allergies. The cost of allergy testing, whether by pricking the skin or blood tests, can be high and could delay diagnosis and appropriate treatment. Even after diagnosis, medications like epinephrine auto-injectors, crucial for emergency situations, can be a significant financial burden for some families. The field of allergen-free food products may be the most important cost factor. In contrast to common foodstuffs, these specialised products are sometimes offered at a premium compared with other foods and can lead to restrictions on access for those who need them or create additional barriers in the maintenance of good nutrition.

Market Opportunity

Development of Novel Diagnostics

The market for food allergy has enormous potential due to new diagnostic developments. The accessibility and empowerment of patients to take charge of their health could be significantly improved through home-based testing kits. Moreover, noninvasive blood tests are a potentially more convenient and precise alternative to conventional methods of diagnosis, facilitating the choice of medicines and speeding up decision making. The landscape of food allergy management is expected to change with these innovations.

Advancements in Oral Immunotherapy (oit)

Oral Immunotherapy OIT is a game changer in the market for food allergy. OIT has the potential to cure and desensitize the immune system to allergens, unlike traditional medicines that treat symptoms. This implies that allergy patients are less dependent on the use of medicines, reducing healthcare costs and significantly improving their quality of life. The market has tremendous potential for further investment in OIT research and development, which could lead to a revolution in food allergy treatment.

Regional Insights

North America is the most significant global market shareholder and is expected to expand substantially during the forecast period. The scene of food allergy in North America is growing exponentially. The market is driven by an alarming rise in allergies, especially for children. As a result, there is a demand for better diagnostics, lifesaving epinephrine for emergencies, and a wider variety of allergen-free foods. From diagnosis to delicious, safe meals, the market caters to managing food allergies across the board.

• The United States food allergy market. The United States is likely the dominant player within North America's food allergy market due to its large population, high prevalence of allergies, and advanced medical facilities.
• The Canadian food allergy industry. Canada's market is growing due to growing awareness of food allergies, coupled with an increase in diagnoses, which fuels demand for solutions.

These factors are estimated to drive the North American food allergy industry growth.

Asia-Pacific Food Allergy Market Trends

The Asia Pacific region is a pivotal market for the food allergy industry. The market in Asia Pacific will also be stimulated by the increasing focus of key players on expanding into new Asian markets, a large customer base and rising awareness about food allergies.

• China food allergy industry. China is a major player due to its large population and rising disposable income, leading to increased healthcare spending and demand for allergy solutions.
• Japan food allergy market. Japan already has a high level of awareness of food allergy and a developed healthcare infrastructure, which is expected to contribute to the growth of the market.

Thus, the factors above are estimated to boost the Asia-Pacific food allergy market growth.

Treatment Insights

The market is segmented into antihistamines, adrenaline, oral immunotherapy, and others. Oral Immunotherapy dominates the treatment segment. The future of food allergy treatment will be dominated by oral immunotherapy (OIT). Unlike medication, it desensitizes the immune system to offer a potential cure rather than relief of symptoms. The growth of the OIT market is driven by this shift from management to treatment.

Distribution Channel Insights

The market is segmented into hospital pharmacy, retail pharmacy, and online pharmacy. Hospital pharmacy dominates the distribution channel segment. Due to two key factors, hospital pharmacies currently dominate the market for food allergy, contrary to the general distribution of medicines. First, anaphylaxis patients may need immediate access to epinephrine autoinjectors which can be provided by hospitals in severe cases. Second, specialists in hospital settings often administer and monitor OIT, a promising treatment, which requires on-site access to medicinal products.
