Choosing a good product range — and why it matters
Two tomatoes are not the same tomato. Where and what you buy changes the quality of what ends up on the plate.
"It's on the supermarket shelf" is not a guarantee that a product is clean or good for you. Front-of-pack words like "natural", "farmhouse" and "wholesome" are loosely regulated and often mean little. The genuine differences between products — ingredient quality, how much they've been processed, what's been added, and how the raw ingredients were grown or reared — are real, and they add up over a lifetime of meals.
This isn't about spending the most money or shopping at one particular shop. It's about choosing ranges and retailers with stronger sourcing and ingredient standards, and reading the label rather than the marketing. A retailer with a reputation for provenance and tighter standards — Waitrose is a common UK example, but the principle matters more than the name — does a lot of that vetting for you.
🥫 Fewer, recognisable ingredients
The shortest ingredient list usually wins. Better ranges tend to use fewer additives, emulsifiers, cheap seed-oil fillers and hidden sugars. If you wouldn't have the ingredient in your kitchen, it's a processed-food flag.
🐄 Provenance & welfare
Higher-welfare, grass-fed, free-range and clearly-sourced meat, eggs and dairy tend to come with better fat profiles and fewer routine additives — and the traceability means you actually know what you're eating.
🍓 Lower chemical load
Choosing trusted suppliers and, where affordable, organic reliably lowers your pesticide-residue load. (Note: organic mainly cuts pesticides — it doesn't automatically mean lower heavy metals, which come from soil and water, so variety still matters.)
🐟 Better fish & oils
Responsibly-sourced oily fish and genuine extra-virgin olive oil (single-origin where you can) deliver the omega-3s and polyphenols you're actually buying them for. Cheap "olive oil" blends often aren't the real thing.
🏷️ Read the back, not the front
Flip the pack. Check the sugar (per 100g), the length of the ingredient list, and whether the first ingredients are the ones you expect. The front of pack is advertising; the back is the truth.
💷 Spend where it counts
You don't need premium everything. Prioritise quality on the things you eat most and the things most prone to additives — meat, fish, dairy, oils, bread — and don't overpay for vegetables and pulses, which are excellent value anywhere.
A short watch-list: additives worth avoiding
Most additives are harmless — a scary-looking name or "E-number" doesn't make something dangerous (vitamin C is E300). The real issue is ultra-processed food built on a long list of cosmetic additives that exist to make cheap ingredients look, taste and keep better, not to nourish you. A few, though, have genuine safety question marks and are worth steering clear of:
- Artificial smoke flavourings. "Liquid smoke" condensates that fake a smoked taste in sausages, bacon, cheese, crisps, soups and sauces. The EU is banning eight of them (from 2024, with phase-out periods) after its food-safety authority couldn't rule out that they damage DNA. Choose genuinely smoked — or simply unsmoked — versions.
- Artificial trans fats — "partially hydrogenated" oils. The one fat with no safe level; mostly restricted now, but worth a check on imported baked goods and cheap margarines.
- The "Southampton Six" colours — tartrazine (E102), quinoline yellow (E104), sunset yellow (E110), carmoisine (E122), ponceau 4R (E124) and allura red (E129). Linked to hyperactivity in some children, so UK law makes products carry a "may have an adverse effect on activity and attention in children" warning. Most UK brands have dropped them — watch sweets, squash and brightly-coloured snacks, especially for kids.
- Nitrites in processed meat (E249–E252) — part of why bacon, ham and salami are classed as cancer-linked. Another reason to keep processed meat occasional.
- Titanium dioxide (E171) — a whitener in some sweets, icing and chewing gum. Banned across the EU and Northern Ireland since 2022 over DNA-damage concerns; Great Britain has kept it for now but is reviewing it — easy enough to avoid.
You don't need to memorise E-numbers. The simplest filter is the one above: the more a product leans on additives that only colour, flavour or preserve, the more processed it is — cook from real ingredients where you can and it mostly takes care of itself. (And not every demonised additive deserves it — MSG, for instance, isn't on this list; the evidence doesn't support the old fears around it.)
The simple version: buy mostly food that looks like food, from a range you trust, and read the label. Doing that consistently quietly removes a large slice of the additives, hidden sugar and poor-quality fat that creep in through ordinary processed groceries.
