A rising star in food allergen research: proteomics of shellfish allergen by SCIEX Community | Blogs, Food / Beverage, Life Science Research, ProteomicsIt’s important to know what you’re eating, especially if you suffer from a food allergy. About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion
