  1. Hi, lets start! Healthy Drink!!

    The Miracle of Green Tea

    Is any other food or drink reported to have as many health benefits as green tea? The Chinese have known about the medicinal benefits of green tea since ancient times, using it to treat everything from headaches to depression. In her book Green Tea: The Natural Secret for a Healthier Life, Nadine Taylor states that green tea has been used as a medicine in China for at least 4,000 years.

    Today, scientific research in both Asia and the west is providing hard evidence for the health benefits long associated with drinking green tea. For example, in 1994 the Journal of the National Cancer Institute published the results of an epidemiological study indicating that drinking green tea reduced the risk of esophageal cancer in Chinese men and women by nearly sixty percent. University of Purdue researchers recently concluded that a compound in green tea inhibits the growth of cancer cells. There is also research indicating that drinking green tea lowers total cholesterol levels, as well as improving the ratio of good (HDL) cholesterol to bad (LDL) cholesterol.

    To sum up, here are just a few medical conditions in which drinking green tea is reputed to be helpful:

    cancer
    rheumatoid arthritis
    high cholesterol levels
    cariovascular disease
    infection

    impaired immune function

    What makes green tea so special?

    The secret of green tea lies in the fact it is rich in catechin polyphenols, particularly epigallocatechin gallate (EGCG). EGCG is a powerful anti-oxidant: besides inhibiting the growth of cancer cells, it kills cancer cells without harming healthy tissue. It has also been effective in lowering LDL cholesterol levels, and inhibiting the abnormal formation of blood clots. The latter takes on added importance when you consider that thrombosis (the formation of abnormal blood clots) is the leading cause of heart attacks and stroke.

    Links are being made between the effects of drinking green tea and the “French Paradox.” For years, researchers were puzzled by the fact that, despite consuming a diet rich in fat, the French have a lower incidence of heart disease than Americans. The answer was found to lie in red wine, which contains resveratrol, a polyphenol that limits the negative effects of smoking and a fatty diet. In a 1997 study, researchers from the University of Kansas determined that EGCG is twice as powerful as resveratrol, which may explain why the rate of heart disease among Japanese men is quite low, even though approximately seventy-five percent are smokers.

    Why don’t other Chinese teas have similar health-giving properties? Green, oolong, and black teas all come from the leaves of the Camellia sinensis plant. What sets green tea apart is the way it is processed. Green tea leaves are steamed, which prevents the EGCG compound from being oxidized. By contrast, black and oolong tea leaves are made from fermented leaves, which results in the EGCG being converted into other compounds that are not nearly as effective in preventing and fighting various diseases.

    Other Benefits

    New evidence is emerging that green tea can even help dieters. In November, 1999, the American Journal of Clinical Nutrition published the results of a study at the University of Geneva in Switzerland. Researchers found that men who were given a combination of caffeine and green tea extract burned more calories than those given only caffeine or a placebo.

    Green tea can even help prevent tooth decay! Just as its bacteria-destroying abilities can help prevent food poisoning, it can also kill the bacteria that causes dental plaque. Meanwhile, skin preparations containing green tea – from deodorants to creams – are starting to appear on the market.

    Harmful Effects?

    To date, the only negative side effect reported from drinking green tea is insomnia due to the fact that it contains caffeine. However, green tea contains less caffeine than coffee: there are approximately thirty to sixty mg. of caffeine in six – eight ounces of tea, compared to over one-hundred mg. in eight ounces of coffee.

  2. BEETROOT for winter health

    Not only is beetroot great for boosting stamina and making muscles work harder, it also contains potassium, magnesium and iron as well as vitamins A, B6 and C, and folic acid. Beets also contain carbohydrates, protein, powerful antioxidants and soluble fibre. What’s more, just three baby beetroot equal one of your recommended five portions of fruit and vegetables a day.

    Research has shown that beetroot can help reduce blood pressure as well as its associated risks such as heart attacks and strokes. This is because the high content of nitrates in beetroot produce a gas called nitric oxide in the blood which widens blood vessels and lowers blood pressure. A daily dose of 250ml of beetroot juice or 1 to 2 cooked beetroot (approx. 100g) can help dramatically reduce blood pressure and its associated risks.

    Betacyanin, the pigment that gives beetroot its colour, is also an antioxidant. Antioxidants are believed to help reduce the oxidation of LDL cholesterol, in turn protecting artery walls and reducing the risk of heart disease and stroke.
    Folic acid

    Beetroot contains folic acid which is essential for normal tissue growth. Folic acid is crucial to the development of a baby’s spinal cord during the first three months of pregnancy and can help prevent spinal cord defects such as spina bifida. Beetroot also contains iron so is a fab pick-me-up for mums-to-be suffering from fatigue during pregnancy. Expectant mums must remember though that cooked beetroot has lower levels of folic acid than raw beetroot.
    Reduces risk of osteoporosis

    Beetroot contains the mineral silica. This helps the body to utilise calcium, which is important for musculo-skeletal health and reducing the risk of osteoporosis.
    Lowers cholesterol

    Beetroot contains soluble fibre, which has also been shown to have cholesterol lowering capabilities. It also contains carotenoids and flavonoids, which help prevent LDL or ‘bad’ cholesterol from being oxidised and deposited in the arteries.
    Stabilises blood sugar

    Since Roman times, beetroot has been viewed as an aphrodisiac. Beetroot is virtually fat free and low in calories. Although it has a ‘medium’ GI (Glycaemic Index) of 64, It has an extremely low GL (Glycaemic Load) of 2.9 which means it’s converted into sugars very slowly and therefore helps to keep blood sugar levels stable.
    Treats anaemia and fatigue

    Beetroot’s iron content means it’s good for those with anaemia and fatigue.

    Bon appetit 🙂
