Sometimes called "nature's crayons", carotenoids are a huge family of colorful plant pigments, many of which act as precursors of Vitamin A. Carotenoids are responsible for the red in tomatoes, the orange in carrots, and the yellow in squash. They are also present in green plants such as spinach, where they are obscured, or masked, by green chlorophyll. About 600 carotenoids have been identified so far -- 50 to 60 of which appear in our food supply.
The first clues linking carotenoids and health appeared in the 1970's. Researchers observed populations around the world and found that in areas where diets were high in fruits and vegetables, the rates for certain cancers were low. Conversely, in populations where fruit and vegetable intake was low, the rates of these cancers were high. These findings spurred many new research efforts focusing on different aspects of the diet/disease equation, including high-fiber versus low-fat intake, vegetarian versus meat diets, and the intake of specific nutrients found in fruits and vegetables -- especially beta-carotene.
Beta-carotene quickly became the "star" in both scientific literature and the media, as research showed that diets high in beta-carotene-rich foods clearly offered health benefits distinct from those provided by other dietary factors. But while beta-carotene is the most famous carotenoid, it is just one member of a large "family" with about 600 members, including alpha-carotene, gamma-carotene, zeta-carotene, lycopene, lutein, zeaxanthin and beta-cryptoxanthin. Research continues to unravel healthful roles for the other carotenoid family members, as well as beta-carotene.
Beta-carotene never appears in isolation in fruits and vegetables, and neither do the other carotenoids. Broad-spectrum carotenoids work together in fruits and vegetables to promote health, with optimal levels and ratios of each required for optimal protection.
Recognizing the impressive benefits of a diet high in carotenoid-rich fruits and vegetables, health experts have establised a series of official dietary recommendations.
Clear as these recommendations are, it remains equally clear that they aren't being met! Recent studies showed that on any given day:
In fact, although some experts recommend consuming at least 6 mg of carotenoids daily, scientists estimate that most of us are actually getting only about 1.5 mg per day -- a significant carotenoid gap.
This gap is not unique to the American diet, according to Dr. Gladys Block of the Division of Cancer Prevention and Control at the US National Cancer Institute. "It is likely that substantial public health benefit could be achieved if consumption of fruits and vegetables were greatly increased over the levels seen in the United States and other industrialized nations."
Following nature's "blueprint", GNLD scientists designed Daily Carotenoid Complex® using whole foods, not isolated carotenoids such as beta-carotene. Single carotenoids do not occur in isolation in natural foods -- they occur with their other carotenoid "family members". In fact, the importance and uniqueness of the carotenoid group lies in their family structure -- each member contributes protective benefits and works together as a team to provide maximum benefits.
Many factors affect absorption of carotenoids in the diet. For example, in raw fruits and vegetables, carotenoids are bound to proteins -- as little as 1% of the beta-carotene in raw carrots may be absorbed. Heating food (as in cooking or canning) can denature, or break down, carotenoids and may cause loss due to oxidation. What's more, very high levels of a single carotenoid can inhibit absorption of other important carotenoids.
Due to the strength of independent research studies and the leading-edge technology that the product represents, GNLD was able in 1996 to demonstrate to patent examiners in the United Kingdom that Daily Carotenoid Complex® is a unique, advanced nutritional supplement. The result was the issuance of British patent no.2.274,235, protecting Daily Carotenoid Complex® from imitation until January 13, 2013.
