The TreEat Study- Can Early Introduction of Tree Nuts Prevent Tree Nut Allergy in Infants with Peanut Allergy
Early and regular ingestion of the common allergens, peanut and egg has been shown to be an effective allergy prevention strategy. It is not clear whether this is also true of tree nut allergy. Current practice in many Australian allergy clinics for children with peanut allergy (high risk of tree nut allergy), is to advise families to introduce each individual tree nut into their child's diet via a cautious home introduction protocol without prior allergy testing (screening). The safety and effectiveness of an early and regular ingestion strategy for the prevention of tree nut allergy has not been formally evaluated and it is known that around a third of children with peanut...

Ultra-processed Food Consumption, Gut Microbiota, and Glucose Homeostasis
Advancing age is associated with gut dysbiosis, low-grade chronic inflammation, progressive insulin resistance, and increased risk of type 2 diabetes (T2D). Prediabetes is present in 45-50% of middle-aged/older adults, and declines in glucose tolerance are evident in the third or fourth decade of life. Thus, there is an urgent need to identify new approaches for the prevention of type 2 diabetes among middle-aged adults. Observational research has linked intake of ultra-processed foods (UPF), which comprise ~60% of total energy intake in US adults, with increased risk of T2D. Ex vivo and animal research suggests that components of UPF alter gut microbiota composition and initiate...

Omalizumab as Monotherapy and as Adjunct Therapy to Multi-Allergen OIT in Food Allergic Participants
This study is a multi-center, randomized, double-blind, placebo-controlled study in participants 1 to less than 56 years of age who are allergic to peanut and at least two other foods (including milk, egg, wheat, cashew, hazelnut, or walnut). While each participant may be allergic to more than two other foods, the primary endpoint/outcome in this study will only be assessed in peanut and two other foods for each participant. The primary objective of the study is to compare the ability to consume foods without dose-limiting symptoms during a double-blind placebo-controlled food challenge (DBPCFC), after treatment with either omalizumab or placebo for omalizumab.

The Effects of Oral Fructanase Administration on Gastrointestinal Symptoms After Inulin Challenge in Healthy Adults
The carbohydrate inulin (from chicory root) is a healthy prebiotic ingredient found in dietary supplements and fortified foods (Nagy et al). Inulin is representative of a broader class of typically health-associated, yet fermentable carbohydrates called fructans that occur naturally in many vegetables, fruits, and wheat. Fructans, or long chains of fructose units, are resistant to human digestive enzyme hydrolysis and transit intact to the small intestine and colon where they undergo rapid fermentation by intestinal microbes. This microbial metabolism of fructans produces gas and other fermentation byproducts that can lead to excess gastrointestinal (GI) symptoms like abdominal...
