World Food Day 2018 food waste

Want some tips on how to cut down your food waste? IFNH member Dr Masento shares her top 5 tips for World Food Day 2018.

Tuesday 16th October is World Food Day 2018, which, this year, has a theme of #ZeroHunger and focuses, along with other initiatives, on the difference that cutting down on food waste would make. We asked Dr Natalie Masento, Postdoctoral Research Fellow in the IFNH, who has been working on consumer perspectives of household food waste, to share her top five tips for reducing food waste in your home.

  1. Write a shopping list

Planning what you need to buy at the supermarket might seem like a time-consuming activity, but research has shown that those who plan their shopping produce 20% less food waste compared to those that don’t write a shopping list (1). Using a shopping list template can help make writing the list easier. Using a table and having columns for each food group such as ‘Vegetables’, ‘Fruit’, ‘Cold’, ‘Dry’, ‘Freezer’ helps you think about what you need in different parts of the kitchen and this also helps when walking around the supermarket.

  1. Cook a ‘what’s left meal’ once a week.

As much as we might plan in advance what to buy at the supermarket, it’s still easy to end up with ingredients left in the fridge or cupboards. Having a look at what is left and creating meals to use up these ingredients is a great way to reduce food waste. Vegetables are a commonly wasted type of food, yet it’s easy to make vegetable soup or a tomato-based sauce with added vegetables – or even a stir-fry with any vegetables that are sitting around in your fridge.

  1. Understand what labels mean.

Understanding the difference between ‘Best Before’ and ‘Use By’ is important when thinking about food in your home. ‘Best Before’ dates are about food quality. Manufacturers provide these dates to suggest when you should eat your food for best taste and texture. Eating food past this date is still safe, so there is no need to throw out food past this date. However, ‘use by’ dates relate to food safety and provide a warning that food past this date may not be safe to eat.

So, while regularly checking food for ‘use by’ dates is a good idea so you can ensure you use those items in time, checking ‘best before’ dates does not matter and should not factor into whether a food item should be thrown away.

  1. Use your freezer

In UK households, bread is the most wasted food item (2), but lots of people don’t realise how easy it is to freeze bread. On purchase day, put sliced bread in the freezer, then when you want a slice or two, defrost either in the toaster or use the defrost setting in the microwave. Using your freezer for food like bread is an easy way to ensure you use food when you need it, rather than not using it and letting it go bad. This approach also helps with portion control, so you only take out the amount of bread you need per day instead of having the whole loaf available for a late night serving of toast.

  1. Know your stuff about storage

Certain fruits such as apples, avocados, ripe bananas, tomatoes are known to release ethylene gas. If these are stored with ethylene sensitive foods such as asparagus, broccoli, garlic and strawberries, they are more likely to ripen and spoil quicker, making them more likely to end up in the bin. Knowing where to correctly store your food and ensuring you store certain foods separately can save them from spoiling too early and ending up in the bin.

Household food is a big problem, with the amount of food waste produced in homes more than half, 53% of the total food waste produced. That is more than supermarkets (5%), restaurants (12%), food processing (19%) and food production (11%) combined(3). If we all made small changes to our habits, following one of the tips provided, we would significantly reduce the amount of food waste in our homes.
