National Nutrition Month: Finding our Way Back to True Foods

Posted by Candace Burch on Friday, 18 March


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.

Too many of the flavors we savor are artificial and too many of the foods we have become accustomed (or addicted) to are loaded with hidden sugars and additives.

And though townspeople admit that, "it can get depressing for people who weren't born here, especially in December," the local mindset is that living in darkness is just a normal part of life. Isn't there something they do to stay happy in the absence of the sun? Not really. "We just deal with it! Polar People don't mind!" (Hersher, 2016).

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.)
