Consumption advice
Eat fresh red radishes with their skin alongside meat and seafood meals; their mild heat stimulates bile and supports efficient digestion.
Best preparation methods
Wash them well and eat them fresh, cold and crunchy, or slice them thinly with lemon juice and mint; avoid cooking them, to keep their crunch and beneficial mustard oils.
Important Nutritional Note
Radish is a great friend of the liver and regular digestion, and a wonderful choice for something to munch on between meals when you feel peckish, with hardly any calories.
