The findings imply that young individuals may suffer long-term consequences, particularly in terms of cognitive flexibility. Few studies have examined the impact that feast or famine has on the developing brain in isolation from other variables that contribute to adversity, despite the fact that fo
The study found that feeding history affects synapses on dopamine neurons as well as dopamine release.
One key behavioral difference involved cognitive flexibility: the ability to generate new solutions when the world changes. But there may be times when kids cannot access food programs, such as during summer vacation. Programs may also inadvertently create a feast and famine cycle when benefits are distributed with weeks between payments, potentially leaving impoverished families unable to afford food at the end of each payment cycle. According to a recent report from the U.S. Department of Agriculture, 6.2% of households with children — 2.3 million households total — were food insecure in 2021.
The well-fed and food-insecure mice were tested as adults in both certain and uncertain settings, with noticeable differences in cognitive flexibility. Food-insecure mice were more flexible in uncertain situations than well-fed mice, while well-fed mice were more flexible in more stable situations.
