Roots, corms, leaves.
Both the tubers and the leaves of taro are edible, which make it a valuable cultivated species. It can't be consumed raw, because its cells have a content of toxic calcium oxalate and raphides that have a shape similar to a needle. Keeping the roots in cold water for one night eliminates most of these toxins, which are also destroyed by cooking. Small round taro corms are sold after being peeled and boiled. Afterwards they are packed in cans or bags in their own liquid, as well as frozen. The content of vitamins and minerals is higher in the leaves. It can also serve as an ornamental plant. Anthocyanin study experiments have made use of the taro, focusing in particular on the abaxial and adaxial anthocyanic concentration. The color of the roots is light purple, since they contain phenolic pigments. They are rich in natural sugars that give it a special sweet nutty taste after boiling, baking or roasting. It consists of fine small grains and it's a popular choice for baby food because the starch in its composition can be easily digested. The leaves are richer in proteins and the vitamins A and C. Both the young leaves and the stems are edible but must be boiled twice in order to eliminate toxins and improve their taste. Including taro roots in your diet has been known for a long time to improve digestion. No less than 27% of the daily recommended amount of dietary fibre can be supplied by a single serving of taro roots. As a result, it is an excellent choice for a balanced digestion. Fibre plays a critical role in the gastrointestinal tract because it bulks up the stool and facilitates regular bowel movements. This is essential for a proper digestion and can treat or prevent many conditions such as constipation, diarrhea, excess gas, bloating or cramping. It can also reduce the risk of developing several types of cancers. A healthy digestive system provides a general boost to the entire body. Taro roots also help preventing cancer by improving the overall level of antioxidants. They provide many compounds that are able to destroy free radicals in the body and strengthen the immune system, such as the vitamins A and C, as well as a number of phenolic antioxidants. Free radicals are produced by the human metabolism as a by-product and can alter the chemical structure of cells, triggering the formation of tumours. If they are controlled properly, the risk of many serious diseases is greatly reduced. One particular compound in taro roots, cryptoxanthin, has been found to protect from oral and lung cancer. Dietary fibres also balance the production of glucose and insulin, so they are very useful in the prevention of diabetes. Taro roots provide a massive dose of fibres, which reduce the risk of diabetes by keeping the glycemic levels under control at all times. Even people who already suffer from diabetes can benefit from the fibers in taro roots. They can prevent the wild glucose level swings that are the main danger of this disease. Taro roots are a major source of potassium, which is one of the essential minerals that the body constantly needs in great amounts. Potassium plays a critical role in the balance of liquids, regulating the transfer of fluids through various tissues and membranes. At the same time, it protects arteries and blood vessels by reducing the stress on them. Blood pressure decreases if the walls of arteries are relaxed, significantly lowering the overall stress placed on the whole circulatory system. Potassium is even able to improve the transfer of fluids between neural membranes and reduce blood pressure in the brain. As a result, this mineral has been linked with a more effective cognitive function. Taro roots are very rich in beta-carotene, cryptoxanthin and other powerful antioxidant compounds. Most of them are particularly active at eye level, protecting ocular cells from the damage caused by free radicals. Consuming taro roots can improve vision and prevent conditions such as cataract or macular degeneration. A diet that includes taro roots will provide an optimal dose of vitamins A and C, which are needed for a healthy skin. These vitamins work together to improve the health of cells and heal various issues. They accelerate the healing rate of blemishes and wounds, making the skin glow and reducing the size of wrinkles. These roots are among the best natural remedies for skin health. Taro roots are also a great choice for a strong immune system. This is mainly because of the very high amount of vitamin C, with a single serving providing a significant quantity. This natural antioxidant plays many roles in human health but is best known for increasing the number of white blood cells, which fight against all sorts of toxins and pathogens. The antioxidant activity can reduce the risk of diseases like cancer or heart diseases.
