Burns calories. Swimming burns lots of calories, anywhere from 500-650 per hour depending on how efficiently you swim (you burn more flopping around than swimming cleanly!) and how buoyant you are (the more body fat you have, the more you float and the fewer calories it takes to swim).
Large amounts of vitamins and minerals are found in green barley (Barley Greens) leaves. These include potassium, calcium, magnesium, iron, copper, phosphorus, manganese, zinc, beta carotene, B1, B2, B6, C, folic acid, and pantothenic acid.
