Dogs trained to detect trauma stress by smelling humans’ breath

A pilot study shows that dogs can be taught to recognize the scent of trauma reactions on the breath, which could make PTSD assistance dogs more effective.

Common meat-free proteins may trigger soybean and peanut allergies in some people

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Meat-free proteins based on legumes are increasingly common. But so are allergies to soy and peanuts, which are also legumes. To find out if it’s safe for patients with these allergies to eat legume-based alternative proteins, scientists investigated how frequent cross-reactions are among people with different legume allergies. They found that although people often produce antibodies against multiple legumes, they rarely have a clinically relevant reaction. Soybean and peanut allergy patients are usually not allergic to other legumes. Many people keen to reduce their meat consumption are turning to substitutes made of legumes packed with protein, vitamins, and fiber. But allergies to legumes like soy or peanuts are both common and dangerous. Are patients allergic to particular legumes at risk from meat-free proteins made of legumes even if they contain different legumes? Dr Mark Smits and a team of scientists at University Medical Center Utrecht set out to investigate. “Both protein consumption and the world’s population are increasing which leads to an urgent demand for sustainable protein sources,” said Dr Thuy-My Le, senior author of the study published in Frontiers in Allergy. “An increase in the consumption of legumes may increase the […]

Scientists find inorganic food additives might make babies more vulnerable to allergies

By Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Inorganic nanoparticles used to help process food may be crossing the placental barrier and getting into breastmilk, potentially damaging intestinal regulation and compromising babies’ oral tolerance, predisposing them to food allergies. Nanotechnologies have revolutionized food technology with changes to food production, manufacture, and processing that are intended to make our food safer and healthier. Phytosanitary products, processing aids, food additives, and surfaces that touch food in storage can all transfer nanoparticles that might be consumed by humans. In a review published in Frontiers in Allergy today, Mohammad Issa, at the Université Paris-Saclay, and colleagues pointed out that such a significant change to food production could have unforeseen health consequences. The team presented evidence that suggested that nanoparticles not only cross the placenta to reach developing fetuses but leave them at greater risk of potentially life-threatening food allergies. “Due to the immunotoxic and biocidal properties of nanoparticles, exposure may disrupt the host-intestinal microbiota’s beneficial exchanges and may interfere with intestinal barrier and gut-associated immune system development in fetus and neonate,” said Dr Karine Adel-Patient, corresponding author of the study. “This may be linked to the epidemic of immune-related disorders in children, such as […]
