Evidence of activity in the regions of the brain that control hunger and cravings may prove that walnuts are effective in treating obese patients.
The study was conducted by Harvard Medical School and the Beth Israel Deaconess Medical Center in the United States. Over two, five-day sessions, the study took brain images of 10 volunteers who were obese. During one of the sessions, the volunteers were given drinks with walnuts in them; in the other session, they were given drinks with a placebo.
In addition to the information gathered from the MRI images, the participants reported feeling fuller and more satisfied the week that they were given the drinks with the walnuts in them than the week they were given the placebo.
Published in the online version of the journal Diabetes, Obesity and Metabolism, these findings offer a glimpse of the effects this food has on the body; promoting the trend of consuming controlled amounts of it to satisfy cravings, as it creates a feeling of fullness in the brain.
