Walnuts are one of those nuts that helps you feel full, which means that it increases satiety. Researchers from Harvard Medical School found that people who consumed shakes containing walnuts had an increased level of fullness during the day as compared to people who had placebo shakes. The rich source of protein and fiber makes it a healthy snacking option, especially for vegetarians.
This nut makes melatonin, a hormone that helps induce and regulate sleep, and is present in the bio-available form in them. In a research report, Dr. Russel Reiter, The University of Texas Health Science Center, said that laboratory rats who were fed walnuts showed an increase in blood melatonin concentrations as compared to rats who were fed a controlled diet without the nuts. So, it’s best to add walnuts to your dinner dishes to ensure a good, restful sleep.
