Watercress crowned health champ: why it’s the world’s healthiest veg and how to eat more
Watercress has been crowned the world's healthiest vegetable after scoring perfectly on the CDC’s 41-item powerhouse list. This peppery brassica is exceptionally nutrient-dense for a leafy green, delivering vitamins A, C and K, folate, calcium and iron, plus glucosinolates that form anti-inflammatory sulforaphane. It’s very low in calories (about 10–15 kcal per 100g) and versatile in salads, soups, sandwiches or pesto. It may help lower LDL cholesterol and protect cells via antioxidants, though more research is needed. To maximise absorption, pair it with healthy fats and vitamin C–rich foods. People taking warfarin should keep intake consistent, and lithium users should note its diuretic effect. A typical serving is 40–80g.
