Every year in March, National Nutrition Month focuses our attention on how and what we eat, exhorting us with awareness-raising campaign slogans to "bite into a healthy lifestyle," or as in this year’s theme, to "savor the flavor of eating right." Appealing and important as the messaging is, it does beg the question that what tastes good to us, may not necessarily be good for us.

But if you are not one of the "Polar People" and looking for a solution to flagging mood and energy—especially if it occurs during the fall and winter monthsyou probably do mind, very much. In that case, the possibility that you are deficient in Vitamin D should be a top consideration. (Consider that the Inuit diet is very unusual compared to ours, given that they eat plenty of fatty sea food that is super rich in vitamin D.)
