Karl Henry: Get juiced up
As I sit watching Fat, Sick and Nearly Dead 2 on Netflix - another fascinating documentary by Joe Cross, whose original programme was about him regaining control of his health by embarking on a 60-day juice fast - my mind inevitably turns to the current vogue for juicing.
One of the reasons for the huge popularity of the juicing craze is the promise of weight loss over a three- or seven-day timeframe. And who doesn't love rapid weight loss? Let's look at what exactly a juice detox does for you.
A seven-day juice detox basically cleans the pipes of the digestive system. You are giving your system a break from the deluge of a normal day's eating, and also helping your mind to reset how you think about food. You're also dramatically increasing the quantity of vitamins and minerals that you are putting into your body.
However, there are some downsides. You're not losing fat - the weight loss is made up of fluid and built-up digestive products. It's generally just a quick fix rather than a long-term solution - many people head straight for the takeaway after day seven. And there is lots and lots of sugar in juice.
I think that juices have a place in a healthy diet but to get the very best out of them, follow these rules:
1. Ideally, make them yourself. Some blenders, such as the Nutibullet, lets you include the skin for added fibre.
2. If buying, choose the juice with the shortest shelf life, which will be less processed.
3. Choose juices with a higher rate of vegetables to fruit, meaning less sugar.
4. Green veg is highly nutritious, so look for kale, spinach and broccoli.
