"The World's Healthiest Food: Grow it Yourself, No Garden Needed"

Watercress has been officially named the healthiest food in the world, surpassing other popular superfoods like goji berries and açaí. Researchers found that watercress is packed with essential vitamins, minerals, and antioxidants, making it an excellent immune booster and a natural cough suppressant. It contains more Vitamin C than oranges and lemons and is rich in iron, calcium, potassium, and magnesium. However, consuming excessive amounts of watercress can cause irritation, so it is best enjoyed in moderation as a side dish or topping. The herb can be easily grown at home, even without a garden, as long as the soil is kept moist.
