The Definitive Answer: Yes, Tinned Tomatoes Count
Contrary to some popular misconceptions, tinned tomatoes are a perfectly acceptable and nutritious component of your recommended 5 A Day. Health organisations like the NHS explicitly state that canned or tinned fruit and vegetables contribute towards this target, as long as they are canned in natural juice or water with no added salt or sugar. The canning process preserves most of the nutrients, making them a reliable option all year round, especially when fresh produce is not in season.
Nutritional Powerhouse: Canned vs. Fresh
While fresh tomatoes are a fantastic source of vitamins A, C, and K, as well as folate, canned tomatoes bring their own set of unique nutritional advantages. The cooking process involved in canning actually makes the antioxidant lycopene more bioavailable, meaning the body can absorb and utilise it more effectively. Lycopene is the powerful antioxidant responsible for the tomato's red colour and is linked to various health benefits, including reduced risk of heart disease and certain cancers. Furthermore, studies have shown that canned tomatoes can contain higher levels of calcium and iron compared to their fresh counterparts.
How to Choose the Best Tinned Tomatoes
To maximise the nutritional benefits and minimise potential downsides, it is essential to be selective when purchasing canned tomatoes. The primary consideration should be the added ingredients. Many standard canned tomato products, including some sauces and purees, contain high levels of salt or sugar. To ensure your tinned tomatoes count towards your 5 A Day in the healthiest way possible, always check the label for:
- No added salt: Excessive sodium intake is linked to high blood pressure, so opt for 'no salt added' versions to control your intake.
- No added sugar: Plain, crushed, or diced tomatoes typically have minimal or no added sugar, but more processed sauces may contain it.
- BPA-free cans: Some health-conscious consumers prefer products that use BPA-free can linings, or opt for jarred versions instead.
Making Tinned Tomatoes Part of Your Daily Routine
Integrating tinned tomatoes into your meals is easy and versatile. They are a cost-effective and convenient pantry staple that can form the basis of numerous dishes. For example, a single medium tomato or seven cherry tomatoes count as one portion, and the equivalent 80g serving applies to canned varieties. A single heaped tablespoon of tomato puree also counts as one portion.
Recipes for using tinned tomatoes
- Pasta Sauce: A simple, flavourful sauce can be made by simmering tinned crushed tomatoes with garlic, onion, and herbs.
- Soups and Stews: Add canned chopped tomatoes to bulk up soups and stews, providing depth of flavour and valuable nutrients.

Comparison: Fresh vs. Canned Tomatoes
| Feature | Fresh Tomatoes | Canned Tomatoes | Winner (Contextual) |
|---|---|---|---|
| Convenience | Requires preparation and spoils faster. | Shelf-stable and ready to use, available year-round. | Canned |
| Lycopene Content | Present, but less bioavailable due to cell walls. | Higher lycopene content, more easily absorbed by the body. | Canned |
| Sodium Content | Naturally low in sodium. | Can be high in added salt; requires label-checking. | Fresh (with careful selection) |
| Fibre Content | Good source of fibre. | Also a good source of fibre; some nutrients retained. | Tie |
| Vitamins A, K & Folate | Generally higher levels in raw form. | Retained, but sometimes at lower levels than fresh. | Fresh |
| Versatility | Best for salads and raw preparations. | Ideal for cooked dishes like sauces and stews. | Tie |
Conclusion
Ultimately, tinned tomatoes are a reliable and nutritious way to contribute to your 5 A Day. The belief that only fresh produce counts is a myth, with scientific evidence and health authorities confirming the value of canned varieties. Not only are they convenient and affordable, but the canning process can also enhance the bioavailability of key antioxidants like lycopene. By opting for no-added-salt, no-added-sugar versions, you can enjoy all the benefits with minimal downsides. So next time you're making a pasta sauce, soup, or curry, feel confident in reaching for that can of tomatoes and ticking off one of your daily five portions.
