Eating ice-cream is a good way to manage stress, claim scientists from University of California. According to the researchers, milk and cream contain a large amount of amino acid tryptophan, which has a sedative effect on the brain. Tryptophan calms and improves your mood and sleep. In order not to get more cholesterol than your body needs and at the same time to provide yourself with the necessary amount of tryptophan, it’s enough to eat just one portion of ice-cream.
