Tinned vegetables are a quick, nutritious, convenience food. If buying tinned fruit, tinned in its own juice is the best choice. But all fruit is good for you. They are often cheaper. Check for special offers on tinned fruit, vegetables and frozen vegetables.
Tinned tomatoes are a very good buy.
Choose fruit juice in preference to fruit flavoured drinks. Fruit flavoured drinks may be cheaper but unless they are low in sugar and have added vitamin C, they are not as nourishing. Buy fruit juice and dilute it with a little water to make it go further. Remember, by buying from local Fruit and Vegetable vans and green-grocers you are supporting local employment. If transport is a problem, local shops will often deliver to your doorstep.
