Watercress is considered a very low-calorie vegetable, making it a strategic choice for anyone who wants volume on the plate without piling on calories. Despite its tiny calorie content, each bunch is packed with vitamin K (over 100% of the daily value in a small serving), vitamin C, vitamin A (as beta-carotene), and folate. Calcium and iron are present in interesting quantities for bone health and oxygen transport, while the natural iodine content supports thyroid function.
The peppery leaf also contains glucosinolates that can release phenethyl isothiocyanate, a compound studied for its supposed anti-cancer properties. Rich in lutein and zeaxanthin, watercress may help protect eye health. Finally, its natural nitrates help regulate blood pressure and improve athletic blood-flow efficiency, again with almost no calorie cost. All in all, watercress is a nutrient powerhouse that is low in calories but rich in taste and history—the Romans already cultivated it for its "tonic" virtues.
Tips for incorporating watercress into a balanced diet
Because watercress contributes negligible calories yet plenty of flavor, it is ideal in a mixed salad with diced apple and toasted walnut; a drizzle of light vinaigrette keeps the calories in check. For a warming dish, blend watercress into a creamy soup finished with a spoonful of 0% fromage blanc instead of cream to maintain low calories while adding protein.
If you need a more substantial meal after sport, serve watercress under a grilled fillet of salmon; the fatty fish provides omega-3s while the leaves add vitamins for almost no extra calories. Another balanced idea is a quinoa bowl: mix cooked quinoa, cubes of cucumber, watercress, and a squeeze of lemon—high satiety, modest calories. Finally, swap part of the basil in your usual pesto for watercress to create a peppery green sauce spreading flavor, not calories, on whole-grain pasta or roasted vegetables.
