Silver beet provides power leaves made of vitamins and minerals. Half a cup of raw silver beet can provide you with a healthy serving of almost all the vitamins and minerals you need, especially magnesium, vitamin K, vitamin A, and carotene, in only about 20 kilocalories. It’s full of polyphenols and antioxidants that may help prevent inflammation. The more enthusiastic (and less substantiated) websites also claim that beet and spinach leaves can help maintain blood sugar levels, lower blood cholesterol levels, lower blood pressure, reduce the amount of oxygen needed during exercise, and everything from your volleyball game in the backyard to your potential Olympic marathon to improve. You’re not quite saying that if we all chewed enough green leaves we would achieve not only health but human compassion, world peace, and cooperation, but the implication is up in the air.
