This is the
time of year where days are shorter, darker, and colder, and many of us struggle with keeping our spirits lifted. The “winter blues” is what some
people call it, or it could be Seasonal Affective Disorder (SAD). SAD is defined as a “seasonal
pattern, as it usually appears in the winter months and goes away at the end of
the cold season." It further states, “If you’ve had poor mental health every
winter for two years or more, you’re likely dealing with seasonal affective
disorder.” So, whether it’s the “winter blues” or SAD, symptoms can affect all aspects of daily living and interfere
with productivity. Being proactive with simple steps such as eating healthily
can help.
Most people head for comfort foods, which typically
include more refined carbohydrates and are higher in sugar and unhealthy fats. Many also
increase caffeine intake thinking it will boost energy levels; however,
these choices and temporary fixes will impact blood sugar levels and stress the
body and brain further in the long run. They increase fuzzy thinking and mood
swings, which is not the outcome we're ultimately looking
for. Ideally, we should add specific foods
into our diet that can help alleviate the blues by boosting nutrients like
vitamin D, hormones such as serotonin, and other chemicals that are associated
with boosting our brain’s mood stabilizers. Choosing certain foods like healthy proteins and fats, fermented foods, veggies, fruits, green tea, and a
little bit of dark chocolate can nourish
the brain and body better and give it the nutrients it needs during this
difficult time.
Our brain is made
up of around 60% fat; therefore, it is highly reliant on healthy fats
and omega-3s to function
optimally. Wild-caught Alaskan
salmon, sardines, mackerel, anchovies,
tuna, flax, chia seeds, and walnuts are a few food sources that contain omega-3s. Diets high in fatty fish, which are rich in omega-3s, have been shown to support a healthy mood. Omega-3s can travel easily through the brain
cell membrane to help produce dopamine and serotonin, neurotransmitters involved in mood support. Any of these delicious
foods are simple to add into our diet daily as a snack or in a meal.
Maintaining stable blood-sugar levels throughout the
day makes us less prone to mood swings. Adding protein into our diet supports healthy blood sugar levels and provides amino acids, the building blocks for neurotransmitters (dopamine, serotonin). 5-HTP (5-hydroxytryptophan) is a chemical our body makes from the essential amino acid tryptophan. Once
produced, 5-HTP is transformed into serotonin, a neurotransmitter that
provides a sense of well-being. Tryptophan-rich foods include seeds (pumpkin, sunflower, sesame), nuts,
nut butters, pork, beef, chicken, turkey, cheese, red meat, fish, shrimp, eggs,
beans, tempeh, tofu, kelp, bananas, and milk. I find this time of year I crave more apples with almond butter, and I
think my body is looking for more protein and fat.
Whole eggs are also high in omega-3s,
biotin, tyrosine, tryptophan, and phosphatidylserine (PS). PS is
a naturally occurring phospholipid that is an essential component of our cell
membranes, and a vital component of our neural membranes. It promotes
inter-cellular communication in the brain, and works by aiding the
neurotransmitters involved in mood. It also protects against stress and
decreases cortisol levels. I have my own chickens and typically eat a frittata
using two whole eggs every day.
Fermented foods, like sauerkraut,
kimchi, plain yogurt, and kefir, nourish the gut, which plays
an important role in the gut-brain connection. Ninety-five
percent of serotonin, which is our “feel good hormone,” is produced in the
gut. Studies have shown probiotics to reduce stress hormones like
cortisol. New research is showing a connection between the gut health and
mental health. Foods like yogurt also provide protein, calcium, and vitamin D. Vitamin D has properties of both a vitamin and a hormone, and is important for mood support. Certain foods contain small amounts of vitamin D, like salmon,
tuna, egg yolks, and some fortified foods (yogurt and orange juice); however,
most individuals this time of year will need to also add a supplement.
Dark
green leafy vegetables like collard greens, turnip greens, spinach, and mustard greens can be beneficial for mood health. Fruits such as blueberries, referred to
as a superfood, are high in polyphenols, antioxidants, and folate, which are
linked to increasing serotonin production. Try adding a small amount of dark
chocolate with fruit or at the end of a meal, as it is high in magnesium, which is also associated with reducing stress and stabilizing mood. Dark chocolate with at least 70% cocoa solids
release endorphins that support mood health. As I write this article, I notice lately
that I have been eating more Greek yogurt with blueberries and a small bit of
dark chocolate with sea salt. Other magnesium-rich foods include black beans, avocados, nuts, and seeds.
Top off the day with a nice
hot cup of green tea, which is loaded with L-theanine. L-theanine is an amino acid that is found naturally in green and black teas. It
helps create a calm, centered, non-drowsy feeling and promotes alpha brain waves,
which are associated with a state of wakeful relaxation. Theanine affects the levels of neurotransmitters GABA, serotonin, and dopamine in the brain, which
influence mood, sleep, and stress.
There are
many choices of foods and beverages to consider adding into our diet to help
shake off those winter blues.
