Health Benefits of Giant Taro
Giant taro provides various benefits to health. It is rich in Vitamin C, carbohydrate, zinc, vitamin E, magnesium, and iron which is essential to maintain health.
Prevent scurvy
Scurvy is a health condition that is caused due to the deficiency of Vitamin C in the body. The symptoms occur due to the weakening of bones, blood vessels, and connective tissues that involve collagen. Vitamin C is an antioxidant that is essential for collagen production. (1)
Eliminates free radicals
Vitamin C is an antioxidant that prevents the damage caused due to free radicals, pollutants, and toxic chemicals. The buildup of free radicals leads to the health ailments such as heart disease, arthritis, and cancer. Free radicals build up during the breaking down of food or exposure to tobacco, smoke, and radiation. (2)
Treats acne
Zinc helps to eradicate acne from the skin. It helps to regulate testosterone levels which play a vital role in the formation of acne. It helps to normalize the skin oils and enhance the skin health. Zinc promotes the count of white blood cells and lowers the risk of infection. Zinc also helps to lower the scars which are left by acne. (3)
Balance hormones
Zinc has a positive effect on fertility and hormonal health because it plays a vital role in the production of hormones such as an increase in testosterone naturally. Zinc affects the hormones of the female sex and involves the release and creation of eggs from the ovaries.
Zinc is essential for progesterone and estrogen production which supports reproductive health. The excessive presence or deficiency of estrogens will create problems with mood swings, menstruation, infertility, and early menopause. (4)
Vision
Vitamin E lowers the chances of macular degeneration which is an age-related eye disease that is the cause of blindness. It should be consumed with beta carotene, vitamin C, and zinc. The study shows that a high intake of Vitamin A and Vitamin E improves vision and healing in people who have undergone laser eye surgery. (5)
Treats insomnia
Magnesium can help to get a sound sleep. Those who have low nutrient consumption and low absorption of nutrients are at high chances of getting insomnia. The study shows that people with magnesium supplements have increased sleep time, a high amount of melatonin, and a low level of cortisol which is related to stress. Magnesium helps to lower the symptoms of insomnia effectively, enhance sleep efficiency, sleep onset, and sleep time. (6)
Prevent heart ailments
Magnesium prevents irregular heartbeats, heart damage, and muscle stress. It soothes the nerves and mediates the digestive processes which prevent the ailments such as indigestion, vomiting, cramps, flatulence, abdominal pain, and constipation. The deficiency of magnesium increases the chances of fatal heart disease. (7)
Prevent cramps
Magnesium helps to treat backaches by relaxing kidney stress, back muscles, and muscular tension. It assists in calcium absorption that speeds up the healing of bones. The deficiency of magnesium results in the symptoms such as general fatigue and leg cramps. The adequate intake of magnesium helps to cure the problems of chronic leg cramps. (8)
Brain health
Iron aids the oxygen supply in the blood. About 20% of the oxygen is used by the brain so iron is related to the function and health of the brain. The adequate blood flow in the brain enhances cognition and creates neural pathways which help to prevent cognitive ailments such as Alzheimer’s disease and dementia. (9)
Formation of hemoglobin
Iron is essential for hemoglobin formation and it also provides a dark red shade to the blood. It transports the oxygen up to the body cells. As human beings lose blood in both external and internal injuries, extra hemoglobin is very important. Women lose blood during menstruation every month due to which they have a high chance of getting anemia than men. (10) (11)
