Welcome to Plan4One! If you’re new here—first of all, hello! This blog is your cosy little corner of the internet for healthy, delicious, single-serve meals that don’t waste food, money, or your precious time. And today, we’re diving into winter nutrition—aka how to keep yourself fuelled, happy, and sniffle-free when the weather turns cold.
Whether you’re curled up on the couch or braving the early morning commute, your body needs a few extra things in winter to stay on top form. Let’s unpack the key vitamins for winter immunity, why they matter, where to find them, and which healthy winter foods deliver the goods—with easy Plan4One recipe suggestions, of course!
1. Vitamin C – Your Immune System’s Best Mate
Why It Matters: Vitamin C helps support your immune system, repair body tissue, and fight off those pesky cold-weather bugs.
Where to Find It:
- Citrus fruits (oranges, mandarins)
- Kiwi fruit
- Capsicum (especially red ones)
- Broccoli and Brussels sprouts
Plan4One Tip: Store sliced capsicum in the fridge and throw it into wraps, omelettes, or stir-fries all week.

2. Vitamin D – The Sunshine You’re Probably Missing
Why It Matters: Your body needs sunlight to make vitamin D, and guess what winter doesn’t have much of? Exactly. Low vitamin D = low mood, weak bones, and a grumpy immune system.
Where to Find It:
- Eggs (especially yolks)
- Mushrooms (bonus: pop them in the sun before cooking!)
- Fatty fish (like salmon or sardines)
- Fortified dairy or plant milks
Plan4One Tip: A 15-minute lunchtime walk can help too—sunshine isn’t just for plants!

3. Iron – Because Tired Isn’t a Personality Trait
Why It Matters: Iron carries oxygen around your body. Not enough? You’ll feel like you’ve run a marathon after doing the dishes.
Where to Find It:
- Red meat (beef, lamb)
- Spinach
- Lentils and beans
- Tofu
Plan4One Tip: Pair iron-rich foods with vitamin C (hello, capsicum!) to boost absorption.

4. Zinc – The Cold-Fighting Ninja
Why It Matters: Zinc helps your immune cells do their job and keeps your sense of taste and smell sharp (crucial for those delicious solo meals).
Where to Find It:
- Chicken
- Eggs
- Legumes (chickpeas, lentils)
- Whole grains
Plan4One Tip: Soaking and rinsing legumes before cooking can help make zinc more absorbable.

5. Omega-3s – For Happy Joints and Brains
Why It Matters: Omega-3 fatty acids reduce inflammation, keep your brain humming, and support heart health.
Where to Find It:
- Fatty fish (salmon, sardines)
- Walnuts
- Chia seeds
- Flaxseeds
Plan4One Tip: Freeze individual salmon fillets for fast, fuss-free dinners.

6. Fibre – Because Winter Isn’t a Constipation Competition
Why It Matters: Fibre keeps your gut happy, supports immunity, and helps regulate blood sugar.
Where to Find It:
- Whole grains (brown rice, oats)
- Vegetables (pumpkin, carrots, sweet potato)
- Legumes
Plan4One Tip: Use microwaveable brown rice or quinoa pouches to save time.

7. Protein – Fuel for Warmth and Recovery
Why It Matters: Protein helps repair tissues, keeps you full, and supports immune function. You don’t need heaps—just enough consistently.
Where to Find It:
- Lean meat, poultry, fish
- Eggs and dairy
- Legumes and tofu
Plan4One Tip: Leftover protein? Store in airtight containers and add to wraps or grain bowls.

8. Magnesium – For Muscle Relaxation and Better Sleep
Why It Matters: Magnesium calms the nervous system, helps with sleep, and supports bone health.
Where to Find It:
- Nuts and seeds
- Dark leafy greens
- Whole grains
- Legumes
Plan4One Tip: Having trouble sleeping? Try a warm mug of milk (dairy or fortified soy) before bed.
