Food waste is a growing issue in the UK, both environmentally and economically. A large portion of what ends up in the bin could have been eaten if it had been stored and handled correctly. By understanding how long different foods naturally last and how to store them properly, you can make your ingredients go further and reduce waste. Here’s a guide to help you keep your food fresher for longer and make the most of what you buy.

Understanding Date Labels

One of the simplest ways to cut down on food waste is to understand the difference between “best before” and “use by” dates.

• “Best before” refers to quality, not safety. Food is often still safe to eat after this date if it looks, smells, and tastes fine. This applies to items like dry goods, tinned foods, and many dairy products.
• “Use by” dates, on the other hand, are about safety. You should not eat food after this date, especially perishable items like meat, fish, and ready-to-eat salads.

Trust your senses as well as the label. If something still looks and smells good, it probably is.

Naturally Long-Lasting Ingredients

Some foods naturally keep well and are great staples to have in your kitchen. They can be used over time without losing quality.

• Dry goods such as rice, pasta, lentils, and beans can last for years if stored in airtight containers in a cool, dry place.
• Root vegetables like carrots, parsnips, and beetroot can stay fresh for weeks in the fridge, especially if kept in a perforated bag.
• Cabbages and other brassicas have a long shelf life and can be used in a variety of dishes.
• Eggs often last longer than their date suggests. To check freshness, place an egg in water – if it sinks, it’s still good to eat.
• Tinned and dried foods such as tuna, tomatoes, nuts, and dried fruit are excellent pantry staples that can be used in countless recipes.

Building your meal plans around these ingredients helps reduce the risk of food going to waste.

Proper Storage Extends Freshness

Even the most durable foods can spoil if stored incorrectly. Temperature, humidity, and light all play a role in how long food lasts.

• Fridge: Keep the temperature between 2°C and 5°C. Store meat and fish on the bottom shelf, where it’s coldest, and fruit and vegetables in the crisper drawers.
• Freezer: Freeze leftovers in small portions so you can defrost only what you need. Always label containers with the date.
• Cupboard: Store flour, rice, and pasta in sealed containers to protect them from moisture and pests.
• Fruit and veg: Some fruits, like apples and bananas, release ethylene gas, which speeds up ripening. Keep them separate from other produce to prevent premature spoilage.

A few small changes in how you store food can make a big difference to how long it stays fresh.

Make the Most of Your Freezer

Your freezer is one of the best tools for preventing food waste. Many foods can be frozen without losing quality – even those you might not expect.

• Bread can be frozen in slices so you can take out only what you need.
• Herbs can be chopped and frozen in ice cube trays with a little oil for easy use later.
• Leftovers such as soups, stews, and sauces freeze well and make quick meals on busy days.
• Fruit like berries and bananas can be frozen and used in smoothies or baking.

Using your freezer strategically helps you save both money and time while keeping food out of the bin.

Plan and Rotate Your Food

A simple but effective rule is first in, first out – use older items before newer ones. Regularly check what’s in your fridge, freezer, and cupboards, and plan your meals around what needs using up. This helps prevent forgotten items from spoiling.

Try creating a “use me first” shelf in your fridge for foods nearing their date. It’s a visual reminder to use them before they go off.

Less Waste, More Awareness

Reducing food waste isn’t just about saving money – it’s about valuing the resources that go into producing our food. By learning how to handle and store ingredients properly, you can make the most of what you buy and contribute to a more sustainable lifestyle.

Small changes – like better storage, smarter freezing, and thoughtful meal planning – can add up to a big impact. It’s all about thinking in terms of freshness and longevity, not just dates on a label.
