Research has found that consuming a broth rich in savory taste (umami) can cause subtle changes in the brain that promote healthy eating behaviors and food choices, especially in women at risk of obesity.
“Previous experimental studies have shown that intake of a broth or soup supplemented with monosodium glutamate (MSG), a sodium salt of glutamate, prior to a meal can decrease appetite and food intake, especially in women with a propensity to overeat and gain weight. In a study published March 30 in Neuropsychopharmacology, researchers evaluated changes in the brains of healthy young women after they consumed chicken broth with or without MSG added.
“Previous research in humans studied the effects of umami broths on appetite, which is typically assessed with subjective measures. Here, we extended these findings replicating the beneficial effects of umami on healthy eating in women at higher risk of obesity, and we used new laboratory measures that are sensitive and objective,” said senior author Miguel Alonso-Alonso, MD, PhD, an Assistant Professor at the Center for the Study of Nutrition Medicine.
“The results may open new ways to facilitate healthy eating and reduce food intake in the general population. Many cultures around the world advocate drinking a broth before a meal. Our study suggests the possibility that people at high risk of obesity could benefit from an umami-rich broth before a meal to facilitate healthy eating and healthy food choice,” said Alonso-Alonso. “However, here we only evaluated immediate effects and in a laboratory context. Future research should address whether these observed changes can accumulate and affect food intake over time and/or whether they can be leveraged to help people lose weight more successfully.”
