Green food supplements or "superfoods" are totally natural chlorophyll rich foods. They are made from grasses or algae. Green superfoods have similar properties because they all contain large amounts of chlorophyll. All plants contain at least some chlorophyll; it has been referred to as the "blood of plants" and is similar to haemoglobin at a molecular level. Chlorophyll rich foods build the blood and superfoods contain a wide range of nutrients, amino acids vitamins and minerals. Chlorophyll has been shown to stop bacterial growth; counteract yeast and fungi; and detoxify the body of drugs, heavy metals and carcinogens. Chlorophyll supports the liver; it helps to counteract the toxic effects of modern western dietary habits.
