Boost Immune Function and Aid Weight Loss

Watercress contains 15 mg of vitamin C per cup (34 grams) or 20% of the RDI for women and 17% for males. Vitamin C is well-known for its immune-boosting properties. Vitamin C deficiency has been associated with impaired immunological function and increased inflammation. Vitamin C strengthens the immune system by boosting the production of white blood cells, which fight infections. Though studies in the general population have not convincingly demonstrated that vitamin C reduces your chance of catching a cold, it does lessen the duration of symptoms by 8%.

Watercress may also help with weight loss, however, this has not been examined precisely. It's a very nutrient-dense meal; one cup (34 grams) has only four calories but includes numerous essential elements. If you're attempting to lose weight, including this healthy, low-calorie vegetable in your diet is a must.
