Journal of Internal Medicine has conducted a study that shows a link between vitamin D deficiency and depression. Vitamin D is important to brain function. https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2796.2008.02008.x
Vitamin D is sometimes called the “sunshine vitamin” because it is produced in your skin in response to sunlight. After a day at the beach or hiking outdoors in the sun, don’t you feel happier & more alive? During the winter when you are less exposed to sunshine, do you feel the blues?
Consider taking a vitamin D supplement & adding foods rich in vitamin D including:
- Salmon (wild Alaska with no mercury)
- other fatty fish
- fish liver oils
- animal fats
- cereal – consider hot gluten-free quinoa or oatmeal
- cod liver oil (also contains vitamin A)
If you follow a vegan or vegetarian diet, there’s a chance you are not consuming sufficient vitamin D.
