Canned food is usually inexpensive, convenient, has a long shelf life, and reduces the cost and environmental impact of food waste. Even better, the canning process means that many products are nutritional powerhouses.
“You can lower the cost of any meal — and fill your plate with nutrients — by switching fresh food to canned food,” says Dr. Sarah Schenker.
“During the canning process, the cans and their contents are heated, which can reduce the levels of some vitamins, especially vitamin C – but this means that the remaining nutrients are locked up until the can is opened.”
This preserves many of the water-soluble vitamins (including B and C), which are sensitive to heat and air and are often easily lost during home cooking and storage methods. Proteins, carbohydrates and fats are not affected by the canning process. Most of the minerals are retained, as are vitamins A, D, E and K.
Some canned foods contain more nutrients than fresh ones. Fish, for example, is canned hours after it’s caught, so you know it’s fresh (and should have more water-soluble B vitamins) than fresh fish, which may travel long distances to reach your supermarket shelf.
Dr. Schenker says the key to creating a balanced, nutritious meal is incorporating a good source of protein (meat, fish, eggs, and legumes) – individually or in combination – along with healthy carbohydrates from whole grains (brown bread, rice or pasta) and plenty of vegetables.
When it comes to canned food, prices can vary – a tin of tomatoes can cost from 28p to £1.10. You’ll pay less if you don’t opt for the round-pull cans, and Dr. Schenker says the cans are usually just as nutritional as the luxury brands: “Although the price may affect the flavor because of the quality of the canned products, it won’t affect the nutrition.”
:: The cost-per-portion figures are calculated by taking the price of a meal cooked from scratch using ingredients from a large online supermarket, and then dividing by the number of portions.
