Why? - Fresh berries are bursting with immune boosting vitamin C but the amount they contain can soon plummet if they are stored for any length of time. Frozen berries however have all that goodness locked in making them just as good (if not better) than the fresh stuff but so much more convenient and they can be used in so many ways, not least of all as a low calorie dessert or breakfast topping.
How? - Pop a cup full of frozen berries such as raspberries, fruits of the forest or blueberries into a blender. Add a small tin of pineapple, a splash of fruit juice and a banana and blend for a taste bud tingling, super cool smoothie that works just as well as a speedy breakfast as it does as a snack or a dessert.
Frozen soy beans
Why? - An 80 grams serving of these super convenient, tasty little beans provides 20 per cent of the vitamin C you need in a day plus ten of the 25 grams of soya protein you need to help reduce blood cholesterol. They are also a great source of fibre and slow releasing carbohydrates which means they are great at keeping cravings at bay.
How? - Use them pretty much as you would frozen peas. They taste great added to rice pasta salads or stir fries too or just add them to boiling water for a couple of minutes, drain, sprinkle with a little salt and eat them as a tasty snack.
