Here Comes the Main Course


As a dietitian and lover of food, I am first and foremost inclined to use food as medicine, to go straight to food sources. So, what can we eat to ramp up our intake of vitamins D, C, E and Zinc? Read on for top sources.


Vitamin D: salmon, trout, fortified foods and time in the sun!


Vitamin C: strawberries (it’s the season), broccoli, cantaloupe, bell peppers, tomatoes, kale


Vitamin E: nuts, seeds, leafy greens, avocados (YES!) and trout.


Zinc: oysters, meat, legumes, nuts, seeds, eggs and whole grains


You may have noticed some foods on multiple lists - awesome, those would be great first additions to your grocery list.

This list is by no means exhaustive! It’s meant to be simple. Feel free to Google for more ideas.
