How you can use food to combat seasonal depression
This time of year, the sun is setting earlier, we start to layer up, leaves are falling, and mood can often follow suit – it’s common to feel a little off as winter approaches. Seasonal affective disorder (SAD) is the official term for depression related to the change in seasons, but you don’t need the diagnosis to feel some form of winter blues. Seasonal changes can cause energy levels, motivation and patience to plummet. Why is it that time of year can bring less-than-good vibes with it, and how do we fight this sadness so that we don’t fight ourselves (and those around us!)?
Goodbye sun, goodbye serotonin
There’s a reason you might be starting to feel a little blue. Reduced sunlight can cause a drop in serotonin, aka “the happy neurotransmitter,” that may trigger depression. Serotonin gives us those joyful, calm, excited feelings and is manufactured by our bodies, but we need particular nutrients in order to produce it.
The goal is to keep it level, even with external factors causing it (and us) to get low. In the summer, sunlight promotes vitamin D synthesis from the skin, but when you’re not exposed to sunlight during the winter months, the body needs Vitamin D from other sources. Low levels of Vitamin D has been associated with various mood disorders, including depression and seasonal affective disorder.
Stressed, well past September
The fall can be a stressful time – maybe you’re getting the kids established in a new routine for the new school year or you’re working forward end-of-year goals at work, all while looking ahead to the busy holiday season. Stress, too, can decrease serotonin and deplete your body of B and C vitamins, both of which help create serotonin. Stress also decreases immunity and disrupts your sleep. Without proper sleep, your cortisol stays high, meaning increased sweets cravings and weight gain. So this time of year, if you’re stressed, you’re also likely sick, tired and bummed out.
So how can you cope with seasonal mood swings?
Keep an eye on that sugar, honey
A dietary key to unlocking your happiness and mental health in the winter is keeping your blood sugar stable. Think steady rolling hills, rather than peaks and valleys. This will keep you feeling satisfied and less moody.
Eating sugar or refined carbohydrates (white bread, white pasta, pastries, cookies, etc) lead to a flood of serotonin, making you think you’re happy, but it’s short lived. You will end up feeling even worse and crave more sweets to get that high. To avoid that vicious cycle, limit refined and processed foods, focus on protein with every meal and snack, and eat every 3-4 hours. Prevent your hangry self by bringing high-protein snacks with you (hard-boiled eggs, unsweetened yogurt, a handful of nuts) and preparing meals in advance.
Exercise causes changes in your brain that improve serotonin production. It also decreases anxiety and depression, and it doesn’t take a big time commitment to make a big difference! Start small and celebrate every success, especially when you are feeling down. This will increase your motivation and keep you coming back for more.
Noodle on necessary nutrients
Paying close attention to your nutrient intake this time of year can help stave off feelings of autumnal sadness. To boost your body’s ability to get those good vibes going optimize for foods that contain Tryptophan, Vitamins B, C and D, and Omega-3 fatty acids.
These nutrients all work in tandem to help your system function at its best: tryptophan is the precursor for serotonin, and in order to convert tryptophan to serotonin, your body needs adequate amounts of Vitamin C and B Vitamins. We mentioned earlier how mood boosting Vitamin D is synthesized from exposure to the sun, but it is also found in foods. Omega-3 is an essential nutrient that has been proven to help with depression and brain health – essential nutrients are those that our bodies need, but don’t create.
To make sure these nutrients are a part of your daily diet, stock up on:
- Tryptophan: eggs, fish, poultry, dairy products, whole grains, nuts and seeds, legumes
- Vitamin C: bell pepper, kiwi, orange, broccoli, kale, Brussels sprouts
- B Vitamins: eggs, legumes, meat, poultry, whole grains, nuts
- Vitamin D: salmon, tuna, milk, eggs, mushrooms, dairy
- Omega-3: salmon, chia seeds, walnuts, flax seed, grass-fed dairy and beef
