Processed foods aren’t just microwave meals and other ready meals. The term ‘processed food’ applies to any food that has been altered from its natural state in some way, either for safety reasons or convenience. This means you may be eating more processed food than you realise.
Processed foods aren’t necessarily unhealthy, but anything that’s been processed may contain added salt, sugar and fat.
One advantage of cooking food from scratch at home is that you know exactly what is going into it, including the amount of added salt or sugar.
However, even homemade food sometimes uses processed ingredients. Read on to find out how you can eat processed foods as part of a healthy diet.
What counts as processed food?
Most shop-bought foods will have been processed in some way.
Examples of common processed foods include:
- breakfast cereals
- tinned vegetables
- savoury snacks, such as crisps
- “convenience foods”, such as microwave meals or ready meals
- drinks, such as milk or soft drinksFood processing techniques include freezing, canning, baking, drying and pasteurising products.Dietitian Sian Porter says: “Not all processed food is a bad choice. Some foods need processing to make them safe, such as milk, which needs to be pasteurised to remove harmful bacteria. Other foods need processing to make them suitable for use, such as pressing seeds to make oil.”Freezing fruit and veg preserves most vitamins, while tinned produce (choose those without added sugar and salt) can mean convenient storage, cooking and choice to eat all year round, with less waste and cost than fresh.”
What makes some processed foods less healthy?
Ingredients such as salt, sugar and fat are sometimes added to processed foods to make their flavour more appealing and to prolong their shelf life, or in some cases to contribute to the food’s structure, such as salt in bread or sugar in cakes.
This can lead to people eating more than the recommended amounts for these additives, as they may not be aware of how much has been added to the food they are buying and eating. These foods can also be higher in calories due to the high amounts of added sugar or fat in them.
Furthermore, a diet high in red and processed meat (regularly eating more than 90g a day) has also been linked to an increased risk of bowel cancer. Some studies have also shown that eating a large amount of processed meat may be linked to a higher risk of cancer or heart disease.
How can I eat processed foods as part of a healthy diet?
Reading nutrition labels can help you choose between processed products and keep a check on the amount of processed foods you’re eating that are high in fat, salt and added sugars.
Adding tinned tomatoes to your shopping basket, for example, is a great way to boost your 5 a day. They can also be stored for longer and cost less than fresh tomatoes – just check the label to make sure there’s no added salt or sugar.
Most pre-packed foods have a nutrition label on the back or side of the packaging.
This type of label includes information on energy (kJ/kcal), fat, saturates (saturated fat), carbohydrate, sugars, protein and salt. It may also provide additional information on certain nutrients such as fibre. All nutrition information is provided per 100 grams and sometimes per portion of the food.
