Check how your diet measures up

You can track calories plus seven nutrients in the Nutracheck app.

See at glance how you're doing by opening the app and tapping the white chart icon top right.

The bars will change colour when you exceed the guide amount.

Salt and saturated fat immediately turn red as a warning to keep an eye on these. If you go over on carbs and protein the bar turns amber. It's not a major health concern to go slightly over on these nutrients but it's helpful to try and stick around the guide amount to maintain a healthy balance in your diet.

If you exceed the sugar guide the bar will turn amber to flag up that you should check your diary to see which foods the sugar is coming from. If it's from natural sugars in fruits, vegetables and milk products that's okay – it's foods with added sugar you should try to limit.

The bar chart also shows how many grams you've eaten and what percentage that is of your target. Or you might be more interested in the overall proportion of nutrients in your diet – if so tap the pie chart icon to see how many calories are coming from the three main macronutrients. And all of this is also available on the Nutracheck website.

Finally to add you can see the nutrient profile of an individual food by searching for it then tapping view full nutrition info. Try changing the serving size to see how a smaller or bigger proportion size affects the traffic lights.
