Beating the Winter Blues: The Power of Serotonin-Boosting Foods

With days getting shorter and winter on its way, many of us can start to feel “winter blues” setting in. There are lots of causes, from the sun setting at 4 p.m., to feeling cooped up inside during bad weather, to missing loved ones absent from holiday celebrations. For some, this low feeling can even turn into depression. 

One way to improve mental health and reduce your risk of seasonal depression is through healthy eating. Diets that are generally high in fruits, vegetables, whole grains, fish, and lean meat, such as the Mediterranean diet, are often associated with decreased risk of depression. In addition, there is strong research that shows that eating a diet high in serotonin-boosting foods can help counteract the effects of the shorter and colder winter days. 

Serotonin is a neurotransmitter that is important for mood, sleep regulation, and hunger cues. Our gut contains a high number of serotonin receptors and thus a high quality diet can have great impact on mental health. Foods that are especially high in tryptophan (an essential amino acid) can promote serotonin production and thus possibly have a great impact on emotional well-being. These foods include:

• Salmon
• Nuts and nut butters
• Eggs
• Cheese
• Pineapple
• Turkey

Nuts are also high in magnesium, another nutrient that is associated with combating anxiety and helping to boost mood. To help you and your loved ones keep smiling this winter, try this homemade granola, adapted from CookieandKate.com, that's full of mood-boosting whole grains, dried fruit, and nuts. 

Granola 

Ingredients:

• 4 cups old-fashioned rolled oats 
• 1 ½ cup nuts and/or seeds such as almonds, pecans or pumpkin seeds
• ½ teaspoon salt
• ½ teaspoon ground cinnamon
• ½ cup canola or olive oil
• ½ cup maple syrup or honey
• 1 teaspoon vanilla extract
• ⅔ cup dried fruit such as cranberries, chopped dried apricots, or raisins (opt for ones with no added sugar)

Directions:

1. Preheat oven to 325 degrees Fahrenheit and line a large, rimmed baking sheet with parchment paper.
2. In a large mixing bowl, combine the oats, nuts and/or seeds, salt and cinnamon. Stir to blend.
3. Pour in the oil, maple syrup and/or honey and vanilla. Mix well, until every oat and nut is lightly coated. Pour the granola onto your prepared pan and use a large spoon to spread it in an even layer.
4. Bake until lightly golden, about 30 minutes, stirring halfway (for extra-clumpy granola, press the stirred granola down with your spatula to create a more even layer). The granola will further crisp up as it cools.
5. Let the granola cool completely. Add the dried fruit once cool. Break the granola into pieces.
6. Store the granola in an airtight container at room temperature for 1 to 2 weeks, or in a sealed freezer bag in the freezer for up to 3 months.
