Kohlrabi: the cheap, underrated vegetable worth eating after 60

Kohlrabi is a cheap, light and easy-to-prepare vegetable that can replace calorie-heavy snacks in the diet of older adults. Cooked, it supports gut health and general wellbeing; raw, it adds variety to salads and slaws. Despite its virtues, it remains far less popular than tomatoes, cucumbers and carrots.
