New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food.

The study, published in Nature Metabolism, advances our understanding of what’s happening across the body after prolonged periods without food.

By identifying the potential health benefits from fasting and their underlying molecular basis, researchers from Queen Mary University of London’s Precision Healthcare University Research Institute (PHURI) and the Norwegian School of Sports Sciences provide a road map for future research that could lead to therapeutic interventions—including for people that may benefit from fasting but cannot undergo prolonged fasting or fasting-mimicking diets, such as ketogenic diets.

New research from the University of British Columbia reveals a safe path to overcoming food allergies for older children and others who can’t risk consuming allergens orally to build up their resistance.

It’s called sublingual immunotherapy (SLIT), and it involves placing smaller amounts of food allergens under the tongue.

A study conducted by UBC clinical professor and pediatric allergist Dr. Edmond Chan and his team at BC Children’s Hospital Research Institute found SLIT to be as safe and effective for high-risk older children and adolescents as oral immunotherapy is for preschoolers.

There’s some relief for people with food severe allergies. A study published in the New England Journal of Medicine reports the drug Xolair allows people with allergies to tolerate higher doses of allergenic foods before developing a reaction after accidental exposure. Geoff Bennett discussed more with the study’s principal investigator, Dr. Robert Wood of the Johns Hopkins Children’s Center.
