Health Impact

Cardiovascular Health

Some studies have found that nitrates are debatable by widening your blood vessels; they may help increase blood flow and lower blood pressure. According to one study [1], arugula may lower blood pressure, essential for people with kidney disease.

High levels of carotenoids have been shown in studies to protect against the development of heart disease and lower your risk of heart attack and stroke [2]. Watercress is high in antioxidants such as beta carotene, zeaxanthin, and lutein. Low levels of these carotenoids have been linked to heart disease and hypertension.

Cancer

According to one study [3], arugula is exceptionally high in cancer-fighting compounds. Arugula extract is beneficial in targeting cancer stem cells and inhibiting cancer cell reproduction and invasion in test-tube studies.

Watercress outperformed in one study regarding total phenol content and ability to neutralize free radicals linked to oxidative stress and several cancer types [4].

Diabetes

Research indicates that eating vegetables reduces the risk of developing type 2 diabetes. Arugula is high in lutein and zeaxanthin, two antioxidants beneficial to the eyes. Because diabetes increases your eye problems, eating plenty of lutein and zeaxanthin may help lower your risk of blindness, glaucoma, macular degeneration, and other devastating vision problems. They also aid in reducing blood pressure, which is a significant risk factor for heart disease [5].

Bone Health

Arugula contains Vitamin K and the minerals manganese and calcium, which are all critical for bone health. These are essential nutrients for good bone health. Numerous published studies [6] show that low calcium intake throughout life is linked to low bone mass and a high fracture rate. Inadequate calcium intake contributes significantly to the development of osteoporosis.
