If you going to drink juice, why not try making it yourself? The juice that you purchase in the supermarket has been pasteruised, which means that it's been heated. In this process the oxygen is stripped off in a process called Deaeration, they do this so it doesn't oxidize. This means that it can be stored for extended periods of time, this destroys most of the nutritional properties in the juice and leaves us with some sweet carbohydrate drink, which the producers then add vitamin C to; this gives it a nutritional property.
Juice is meant to be pressed and drunk fresh, so get to it, the new season apples and pears mean that it's a great time to make some fresh juice for the morning, a nutrient blast in a glass.
And juice, it doesn't get much easier than that, if you have excess apples and pears at the end of the week, press them and freeze them in icy pole containers and give them to the kids as a treat on a warm day. Easy peesy.
