Antioxidants Proven To Be Key To Long Life

Research from the The University of Washington suggests higher dose of antioxidents could allow us to live 20% longer and easily reach ages of over 100 in good health.

Antioxidants Proven To Be Key To Long Life: "The International Journal of Food Sciences and Nutrition 2004 published results showing that Reishi caused a significant post-ingestion increase in plasma antioxidant capacity with peak response at 90 min. Increase in urine antioxidant capacity was seen within 3 hours. Results indicate that Reishi intake causes an acute increase in plasma antioxidant capacity.

Reishi is a powerful antioxidant; in a laboratory study Reishi significantly elevated the free radical scavenging ability of blood and was so strong that even after the Reishi extract was absorbed and metabolized the scavenging effect still continued. A compound called GLB 7 actually decreases the production of oxygen free radicals. Dr. Vladimir Kupin of the Cancer Research Centre in Moscow discovered that Reishi was more effective as a free radical scavenger than isolated refined compounds. A laboratory study with fruit flies that have a very similar genetic make up to humans and are often used in experiments proved that Reishi significantly lengthened the life span of those that had been fed Reishi compared to controls.

Cancer and Dietary Antioxidants

Epidemiological studies show that a high intake of anti-oxidant-rich foods is inversely related to cancer risk. Animal and cell cultures confirm the anticancer effects of antioxidants. Selenium and vitamin E reduced the risk of some forms of cancer, including prostate and colon cancer and carotenoids have been shown to help reduce breast cancer risk.

Cancer treatment by radiation and anticancer drugs reduces inherent antioxidants and induces oxidative stress, which increases with disease progression. While clinical studies on the effect of anti-oxidants in modulating cancer treatment are limited in number and size, experimental studies show that antioxidant vitamins and some herbs selectively induce apoptosis (cell death) in cancer cells but not in normal cells and prevent angiogenesis and metastatic spread, suggesting a potential role for antioxidants as adjuvants in cancer therapy. Reishi has been shown to suppress cell adhesion and cell migration of highly invasive breast and prostate cancer cells, suggesting its potency to reduce tumor invasiveness.

Accumulation of excess free radicals causing oxidative damage to cells is one of the contributing factors in ageing and has been implicated in many diseases, including cancer. The human immune system and antioxidant activity becomes weaker and less efficient with age; this reduced effectiveness helps to explain the rising incidence of cancer and life threatening infections in older people. It is thought antioxidant supplements could help to maintain bodily processes and prevent a significant number of degenerative diseases, especially those of the immune, cardiovascular and liver functions. Indeed, antioxidant supplementation has shown a remarkable ability to forestall age related changes to the immune system and even reverse many aspects of immune function in subjects with damaged immune functions.

Extracts from medicinal mushrooms are classified as nutraceuticals, i.e. dietary supplements. Functional food science is a rapidly evolving discipline researching ways to maintain good health and improve homeostasis and thus create conditions for reducing the risk of disease. It is quite distinct from medical and pharmaceutical sciences where the objectives are mainly to eliminate, cure or control diseases rather than to fortify the patient and prevent disease. Functional foods are poised to play an increasingly important role in developed nations to curtail spiraling health care budgets.

It is widely recognized that diet has a critical role in general health and that many types of cancer can be linked to inappropriate diets. Regular consumption of fruits and vegetables (functional foods) are now considered essential ingredients in cancer and coronary disease prevention programs, e.g. the Department Of Health campaign advocating 5 portions of fruit and vegetables a day. Cancer Research UK note, ‘Dietary supplements consisting of whole mushroom extracts are becoming increasingly popular. Unlike most dietary supplements, mushroom dietary supplements contain a veritable Pandora's box of compounds'.

Green Tea has a number of benefits which is being substantiated by growing research and is leading many health experts to agree that the consumption of Green Tea on a regular basis supports health in a number of good ways. Green Tea contains powerful antioxidants called epigallocatechin gallate. Antioxidants help support normal cell functioning thus supporting health at the cellular level. Besides, showing anti-cancer properties, and supporting immune health, Green Tea is good for the skin and is known to retard the signs aging which is why you see it being used in a number of skin products. However, many people do not like the taste of Green Tea. It is an acquired taste to say the least! But concentrated forms of Green Tea are available, like Green Tea Plus. A few drops in your favorite drink gives you just as much Green Tea health benefits as drinking 6 cups of the natural brew! http://www.newvitality.com/shop/green-tea-plus.aspx
