We’ve all heard that processed foods are the enemy of healthy eating – but that’s not the full story. While ultra-processed snacks and sugary treats can do more harm than good, some packaged foods are not only convenient but also packed with nutrients.
From tinned beans to frozen berries, certain processed items can make healthy eating easier and more affordable. Here are sixteen nutritionist-approved options that deserve a spot in your weekly shop.
This article is for general informational purposes only and is not a substitute for professional dietary or medical advice. Nutritional needs vary by age, activity level, and health status. Always read labels and consult a qualified dietitian or healthcare provider for personalised guidance.
1. Frozen Berries
Flash-frozen at peak ripeness, these colourful gems actually retain more nutrients than their fresh counterparts that have travelled long distances. They're packed with antioxidants and fibre.
Keep a bag in your freezer for instant smoothies, porridge toppings, or quick desserts. No washing, chopping, or worrying about them going mouldy before you can use them!
2. Tinned Beans
Rinsing tinned beans reduces their sodium content by up to 40%, making them a nutritional powerhouse. They're loaded with plant protein, fibre, and essential minerals like iron and potassium.
Unlike dried beans, there's no overnight soaking required. Just open, rinse, and add to salads, soups, or make a quick bean dip for instant nutrition.
3. Greek Yogurt
The straining process that creates Greek yogurt results in double the protein and half the sugar of regular yogurt. It's also rich in probiotics that support gut health and boost immunity.
Morning parfaits, post-workout snacks, or as a sour cream substitute – this versatile dairy product does it all while delivering calcium and B vitamins to your diet.
4. Tinned Tomatoes
Surprisingly, the heating process used in canning actually increases the availability of lycopene, a powerful antioxidant that may reduce cancer risk. These kitchen staples have a bright, consistent flavour year-round.
From pasta sauces to curries, soups to casseroles – their versatility is unmatched. Stock up on the no-salt-added varieties for maximum health benefits.
5. Nut Butters
Look for varieties with just nuts and maybe a touch of salt – nothing else needed! The healthy fats and protein in nut butters help keep you fuller longer while supporting heart health.
Beyond sandwiches, try stirring nut butter into porridge, blending into smoothies, or using as a dip for apple slices. A tablespoon delivers energy that lasts for hours.
6. Whole Grain Bread
Modern bread-making techniques have given us shelf-stable loaves that still deliver whole grain goodness. Look for "100% whole grain" on labels and at least 3g of fibre per slice.
The complex carbohydrates provide lasting energy while the fibre supports digestive health. Freeze half the loaf if you won't use it quickly – it toasts perfectly straight from frozen!
7. Tinned Fish
Sardines, salmon and mackerel in tins deliver the same heart-healthy omega-3 fatty acids as fresh fish at a fraction of the price. The soft bones in tinned fish like sardines provide a calcium bonus you won't get from fresh fillets.
Ready to eat with no cooking required, they're perfect for quick meals. Try them on toast, tossed in salads, or mixed with pasta.
8. Frozen Vegetables
Frozen within hours of harvest, these vegetables often contain more vitamins than "fresh" produce that's spent days in transit and storage. The blanching process before freezing actually helps preserve their vibrant colours and nutrients.
Steam them directly from frozen for quick side dishes, toss into soups, or roast them for caramelized goodness – no chopping or washing required!
9. Hummus
Store-bought hummus combines protein-rich chickpeas with heart-healthy olive oil in a convenient, ready-to-eat package. The tahini (sesame paste) adds calcium and iron that many diets lack.
Beyond a dip for veggies, try hummus as a sandwich spread, salad dressing base, or even pasta sauce. Most varieties stay fresh for a week after opening – perfect for healthy snacking on demand.
10. Fortified Plant Milks
Modern processing techniques have given us delicious plant milks fortified with calcium, vitamin D and B12 – nutrients that can be challenging to get on plant-based diets.
Many brands now avoid unnecessary additives while maintaining creamy texture. Use them exactly as you would dairy milk in cereals, coffee, cooking, or straight from a glass. Most varieties stay fresh for 7-10 days after opening.
11. Pre-Washed Salad Greens
The convenience of triple-washed, ready-to-eat greens means you'll actually eat more salads. These leafy nutritional powerhouses deliver folate, vitamin K, and antioxidants with minimal processing.
Keep a container in your fridge for instant side salads, sandwich fillings, or to wilt into soups and pastas. The time saved on washing and chopping means healthier meals happen more often.
12. Jarred Pasta Sauce
Look for varieties with simple ingredients like tomatoes, olive oil, and herbs – many premium brands skip the added sugars and preservatives. The slow cooking process actually increases the availability of lycopene from the tomatoes.
Beyond pasta, use as pizza base, soup starter, or simmer with beans for a quick chilli. A real time-saver that doesn't compromise on nutrition.
13. Rolled Oats
The minimal processing of rolled oats preserves their fibre and protein while making them quick to prepare. They contain beta-glucan, a special type of fibre that helps lower cholesterol and control blood sugar.
Overnight oats, porridge, homemade granola, or as a crunchy topping for yogurt – their versatility is impressive. A single serving keeps hunger at bay for hours.
14. Rotisserie Chicken
A grocery store rotisserie chicken offers lean protein without the hassle of raw meat preparation. Remove the skin to reduce fat content while enjoying the tender, seasoned meat inside.
Shred it for sandwiches, salads, soups, or tacos throughout the week. The bones can even be simmered for homemade stock, making this processed option surprisingly economical and nutritious.
15. Fermented Sauerkraut
Fermented sauerkraut is one of the few processed foods that nutritionists actually celebrate. It’s naturally rich in probiotics, which support gut health and digestion, and it retains plenty of fibre and vitamin C even after processing.
The fermentation process boosts beneficial bacteria that can strengthen your immune system and improve nutrient absorption.
Just make sure you choose a raw, unpasteurised version from the fridge section rather than one that’s been heat-treated on the shelf.
16. Fortified Breakfast Cereals
Fortified cereals often get a bad rap, but when chosen wisely, they can be a quick and reliable source of essential nutrients. Many brands add iron, B vitamins, and vitamin D – nutrients that are commonly lacking in British diets.
The key is to pick varieties that are low in added sugar and high in fibre, such as wholegrain or bran-based cereals.
Paired with milk or a plant-based alternative, a bowl of fortified cereal can be a balanced and easy start to your morning.
