Today the Food Standards Agency will launch a phone application, designed to help people take a 21-day long challenge to cut thier saturated fat intake. The idea is to help people come to better understand the different levels of saturated fat in various food products, hence helping them make better choices about what they consume. All you need to use the application is a web-enabled phone, an iPhone or an iPod Touch; simply donwload the application from the Apple App Store or http://www.food.gov.uk/satfatapp to get started!

The 21-day challenge involves making a small daily change to your diet, to cut down on consumption of saturated fat. These changes can also be shared with friends via Twitter, should you desire to do so. You pick you own challenge for each of the 21-days, which can be something as simple as having skimmed milk on your breakfast on monday, instead of semi-skimmed. Once complete, you can Twitter your success to your friends.
