In the chill of winter, when the body craves warmth and comfort, it's easy to overlook the nutritional powerhouses that can help keep us healthy and strong. But, as a dietitian, I'm here to remind you of the importance of including seasonal fruits and vegetables in your diet, especially those that pack a nutritional punch. So, let's dive into the seven winter fruits and vegetables that should be a staple in every crisper, and explore why they're so special.
Kiwifruit: The Winter Superfruit
If I had to choose just one winter superfruit, kiwifruit would be my top pick. This furry little fruit is a nutritional powerhouse, especially the gold variety, which is currently in season. Just one kiwifruit contains over 100mg of vitamin C, more than three times the amount found in a single orange. But that's not all - kiwifruit has also been shown to relieve constipation and enhance sleep quality. Personally, I think this makes it a must-have for anyone looking to boost their immune system and overall health.
Cauliflower: The Versatile Veggie
Cauliflower is another cruciferous vegetable that deserves a place in your crisper. It's packed with powerful anti-cancer molecules called glucosinolates and isothiocyanates, which have been shown to slow the rate of cancer cells in the body. But that's not all - cauliflower is also a rich source of vitamin C and dietary fibre, supporting cellular and digestive health for just 25 calories per cup. What makes this particularly fascinating is that cauliflower's subtle flavour makes it a versatile ingredient that can be used in a variety of dishes, from stews and soups to salads and stir-fries.
Broccoli: The Anti-Cancer Powerhouse
Broccoli is another cruciferous vegetable that offers powerful anti-cancer molecules. It's also a rich source of dietary fibre, vitamin C, and folate. To keep it crisp and vibrant for days, store it in your refrigerator's crisper drawer or wrap it loosely in a damp paper towel. Broccoli is a versatile ingredient that can be used in a variety of dishes, from soups and curries to sauces and dishes. Don't throw out the stalk - it adds fibre to dishes and can be grated into soup bases, mince dishes, or even oats or smoothies.
Silverbeet: The Immune-Boosting Leafy Green
While spinach usually steals the spotlight, don't forget its powerhouse cousin, silverbeet. Silverbeet is exceptionally rich in beta-carotene and vitamin C, both important for immune function. While spinach is slightly higher in iron, silverbeet still offers decent amounts of non-haem iron, which, especially when consumed with foods high in vitamin C such as tomatoes, can be a good iron source for those who follow a plant-based diet. Silverbeet cooks well, maintaining its strength and structure, which makes it an ideal addition to baked and cooked dishes including casseroles, pasta bakes, risotto, and soups. Plus, it freezes well, so there's less waste.
Carrots: The Nutrient-Dense Root Vegetable
Like apples, carrots can be taken for granted, but nutritionally they really pack a punch. With exceptionally high amounts of the powerful antioxidant beta-carotene, few calories, and a low cost per serve, carrots are a must-have for anyone looking to boost their immune system. High intakes of beta-carotene have been shown to give the skin a natural glow, supporting the natural production of collagen in the body. Carrots can be grated into just about anything, including sauces, mince dishes, soups, and casseroles, or enjoyed baked, roasted, or stir-fried. Super-charge your beta-carotene intake and immune system by drinking carrot juice, too.
Leek: The Prebiotic Powerhouse
The underrated leek is one of a handful of vegetables that acts as a prebiotic in the digestive tract, helping to nourish the good bacteria. A rich natural source of insulin and fructo-oligosaccharides (FOS), these prebiotic fibres pass through the digestive tract undigested, nourishing the gut, improving digestion, and supporting nutrient absorption. Diced leek can generally be added to any dish that you normally start with onion and garlic - think soups, casseroles, risotto, and pie fillings. I always keep a supply of chopped leek in the freezer, ready to add to any sauces or soups I am making year-round.
Apples: The Nutritious Snack
An apple a day really can help keep the doctor away, and is an easy way to get a good whack of nutrients for just a few calories. A single apple contains three grams of fibre, nutrients including potassium (good for heart health and blood pressure), and vitamin C, and has just 60 to 80 calories. Apple skin in particular contains an especially high amount of the antioxidant polyphenols - powerful molecules that feed the good bacteria in the gut and protect the body's cells from damage - more than double the amount of these powerful molecules than the flesh of the apple contains. Keep the fruit bowl stocked up with them for a snack on the run, grate into overnight oats, or bake for delicious and healthier warming desserts.
In my opinion, these seven winter fruits and vegetables are a must-have for anyone looking to boost their immune system and overall health. So, the next time you're at the grocery store, be sure to stock up on these nutritional powerhouses. Your body will thank you for it!
