GINKGO BILOBA The ginkgo, or maidenhair tree, is the oldest surviving tree species on earth. It is the only remaining species of a large order that existed with the dinosaurs in the Triassic period, a tall deciduous tree with fan-shaped leaves. The herbal remedy ginkgo biloba is an extract of the leaves. It is believed to help prevent many conditions associated with aging: including Alzheimer’s Disease, memory loss, stroke, heart disease, impotence.
GINSENG A licorice-flavored root that has been credited for centuries with being everything from an aphrodisiac to a sedative to a restorative. Recent scientific discoveries have linked ginseng to the treatment of high blood pressure. It is referred to as white ginseng when simply sun-dried. When steamed and dried over a fire or with other heat, it takes on a reddish tinge and is called red ginseng. Ginseng is used in soups, for tea and as a medicine.
GREEN A term that refers to products made from materials that are recycled, renewable or otherwise environmentally-friendly.

GREEN TEA Tea made from leaves that are not fermented before they are dried, green tea’s antioxidants are five times higher than black tea. In March 2005, Spanish and British scientists released a study identifying a specific antioxidant compound called EGCG that prevents cancer cells from growing. Green tea is also high in vitamin C.
GMO A GMO, or genetically modified organism, is one whose genetic material has been deliberately altered. Genes are combined from different organisms (recombinant DNA technology) and the resulting organism is said to be “genetically modified,” “genetically engineered,” or “transgenic.” The objective is to locate genes with important traits In the food industry, commercial strains of wheat have been modified by irradiation since the 1950s. The first commercially grown genetically modified food crop was a tomato created by Calgene called the “FlavrSavr.” Calgene submitted it to the U.S. Food and Drug Administration for testing in 1992; the FDA determined that it did not constitute a health hazard and did not need to be labeled to indicate it was genetically modified. It was released into the market in 1994, but was not deemed to have a good flavor; and it was off the market by 1997. Subsequent genetically modified food crops included virus-resistant squash, a potato variant that included an organic pesticide that kills caterpillars, and strains of canola, soybean, corn and cotton engineered by Monsanto to be immune to their popular herbicide Roundup. Animals also can be genetically modified: work is underway on fish that mature more rapidly. Genetic modification (GM) is the subject of controversy: because it can cause abnormalities within the product, the long-term impact on humans is unknown, and detractors would like to see it banned. Laissez-faire supporters simply want such foods to be clearly labeled so consumers can decide for themselves (the European Union and Japan have labeling and traceability requirements).
GUARANÁ The guaraná plant, a woody, climbing shrub of the soapberry family (Paullinia cupana), grows in Brazil and Venezuela. Its seeds contain caffeine, and are added to soft drinks as a stimulant. It also helps to cleanse the body of lactic acid that builds up during exercise. There is an eponymous Brazilian carbonated soft drink made from the guaraná berry. The early inhabitants of the Amazon used guaraná to help maintain stamina and physical endurance.
HERBALS and SUPPLEMENTS
These are products designed to promote health and well-being. They are not always natural, but include all vitamins and supplements, and meal replacements, plus functional foods and beverages.
IRRADIATION Food irradiation is the process of exposing food to ionizing radiation in order to disinfest, sterilize, or preserve food. It is, like most technology involving ionizing radiation, the subject of some controversy regarding its safety. Concerns have been expressed by activist groups that irradiation, by killing all bacteria in food, can serve to disguise poor food-handling procedures that could lead to other kinds of contamination. However, processors of irradiated food are subject to all existing regulations, inspections and potential penalties regarding plant safety and sanitization, including fines, recalls and criminal prosecutions. The effects of food irradiation have been studied for over 60 years. Independent scientific research on the subject has been extensive leading to endorsement of food irradiation by the U.S. Food and Drug Administration, the United States Department of Agriculture and the U.N. World Health Organization as a safe, effective and desirable process for the production of wholesome food.
ISOFLAVONE A phytoestrogen found mainly in soybeans that is thought to have preventive health benefits when used as a nutritional supplement.
