The beginning of winter is focused on holidays. After the new year’s excitement fades, winter can hit hard.

The days are shorter. Sunlight is limited. Schedules feel heavier. Cold or unpredictable weather can disrupt routines and make movement, social connection, and motivation harder to sustain. For many people (myself included), this shows up as the “winter funk” or a general sense of low energy, irritability, or emotional flatness.

While nutrition isn’t a cure-all, the way we feed ourselves during winter can absolutely influence mood, energy, and resilience. Food provides the building blocks for neurotransmitters, supports blood sugar stability, reduces inflammation, and helps the nervous system cope with stress.

Rather than focusing on perfection, winter is a time to focus on support and self care.

Here’s how to nourish your mood through the colder months.

Start With Blood Sugar Stability

Mood and blood sugar are closely connected. When blood sugar swings too low or too high, symptoms can include irritability, anxiety, fatigue, brain fog, and cravings.

During winter, people often skip meals, snack more erratically, or rely heavily on refined carbohydrates for quick comfort — all of which can worsen these swings.

A simple foundation:

• • • Eat three balanced meals daily, avoiding snacks as much as possible
    • Prioritize protein and fiber at each meal

Protein helps stabilize blood sugar and supports neurotransmitter production. Fiber slows digestion and promotes steady energy.

Examples:

• • • Eggs with vegetables + sourdough toast
    • Greek yogurt + berries and nuts
    • Chicken, beans, or lentils with roasted vegetables
    • Soups and stews built around protein, vegetables, + potatoes or sweet potatoes

Stability first — everything else builds from there.

Key Nutrients That Support Mood

1. Omega-3 Fatty Acids

Omega-3s play a role in brain health, inflammation regulation, and mood balance. Lower intake has been linked to higher rates of depression.

Food sources:

• • • Fatty fish (salmon, sardines, trout)
    • Chia seeds
    • Flaxseeds
    • Walnuts

Aim to include omega-3-rich foods a few times per week. If these are not possible, supplementation of at least 1000mg of omega 3 is available (Nordic Naturals is my favorite brand).

2. Vitamin D

Vitamin D is often called the “sunshine vitamin,” and winter is when levels tend to drop — especially because we typically spend so much time inside.

Low vitamin D has been associated with:

• • • Low mood
    • Fatigue
    • Increased risk of seasonal affective symptoms

There are only a few food sources, including:

• • • Fatty fish such as salmon
    • Egg yolks that come from chickens raised in a pasture
    • Fortified dairy or non-dairy milks

Quite honestly, getting enough vitamin D based foods to keep levels up in the winter is very hard. Supplementation is encouraged, anywhere from 2000-5000IUs of vitamin D is recommended.

3. Magnesium

Magnesium supports the nervous system, muscle relaxation, sleep quality, and stress response — all critical during winter months.

Food sources:

• • • Pumpkin seeds
    • Almonds and cashews
    • Spinach and leafy greens
    • Black beans
    • Dark chocolate

This mineral is commonly under-consumed and especially helpful during periods of stress or poor sleep.

4. B Vitamins

B vitamins (especially B6, B12, and folate) are involved in energy production and neurotransmitter synthesis, including serotonin and dopamine.

Food sources:

• • • Eggs, specifically egg yolks
    • Poultry such as chicken + turkey
    • Legumes + beans
    • Leafy greens such as spinach, mustard, collard, or turnip greens, kale
    • Nutritional yeast, often used in the vegetarian world as a replacement for cheese

Inadequate intake can contribute to fatigue and low mood.

Don’t Forget Complex Carbohydrates

Carbohydrates are often misunderstood, but they play a role in serotonin production and can support mood when chosen intentionally.

Helpful options:

• • • Oats
    • Quinoa
    • White potatoes
    • Sweet potatoes
    • Beans + lentils
    • Fruit

Pairing carbohydrates with protein and fat helps prevent energy crashes while still supporting brain chemistry.

Warm, Comforting Foods Matter

Winter is not the season for restriction. It’s the season for nourishment.

Warm foods can:

• • • Improve digestion
    • Increase satisfaction
    • Promote feelings of comfort and safety

Think:

• • • Soups + stews
    • Slow-cooked meals
    • Roasted vegetables
    • Herbal teas
    • Warm breakfasts

Comfort is not a failure — it’s a biological need, especially during colder months.

Hydration Still Matters

It’s easy to drink less water in winter, but dehydration can worsen fatigue, headaches, and mood changes.

Support hydration with:

• • • Water
    • Herbal teas
    • Broth-based soups

Warm fluids count — and often feel more appealing when it’s cold.

Feed Yourself With Compassion

Winter can be harder than we expect. Energy is lower. Motivation shifts. That doesn’t mean you’re doing anything wrong.

Instead of asking:
“What’s wrong with me?”

Try:
“What does my body need right now?”

Often the answer is:

• • • More consistency
    • More warmth
    • More nourishment
    • Less pressure

You don’t need a perfect winter diet. You need one that supports your nervous system, stabilizes your energy, and helps you feel steady.

Food can’t change the season — but it can help you feel more grounded as you move through it.

And sometimes, that’s more than enough.
