A handful of radishes contains just 5 caloriesmaking them a great healthy snack whether you are dieting or just counting the calories. Radishes can also help dieters reduce portion sizes thanks to the crunch factor. It takes between 10 and 30 minutes for the brain to register the 'I'm full' signal from our stomachs so foods that need chewing, like radishes, slow down eating; this gives our bodies time to communicate the 'stop eating' message, meaning we may eat less and in turn lose weight. In addition, radishes have a lovely peppery flavour, so are ideal as a snack on their own, or with a low fat dip like tomato salsa or a tzatziki made with zero % fat yoghurt if you want to keep calories to a minimum.
