MOOD-BOOSTING MOUTHFULS 
MOOD-BOOSTING MOUTHFULS Research shows that a healthy gut does more than support glowing skin and immunity: it actually makes us happier. No surprise, since 50 percent of your dopamine and 95 percent of your serotonin, both happiness neurotransmitters, are produced there. One recent study actually found that after four weeks of a daily probiotic supplement (which supports a healthy gut), participants reported less focus on negative thoughts and experiences. To avoid the dip in mood that often accompanies dreary winter days, fit in a serving of probiotic-rich fermented foods daily.
