Guest guest Posted March 6, 2007 Report Share Posted March 6, 2007 Ancient Wheats and New Perspective by Dr. Elsayed Abdel-Aal ~ January 2005 No.187 ~ Wheat has been used as a food grain since the last Stone Age. It can be considered the oldest domesticated crop grown for food - dating from 8,000-10,000 B.C. In fact, the ancient civilizations such as Egyptian, Babylonian, Greek, Cretan and Roman were highly dependent on wheat and barley as the principal food. Einkorn, Emmer, Khorasan/Kamut and Spelt are among the earliest cultivated wheats and commonly are referred to as " ancient wheats. " Except for Khorasan/Kamut, each of these wheat crops produces hulled or covered grains at harvest, i.e., intact spikelets in which the glumes remain adhered to the grain. The attached hulls may provide physical protection to the grains during planting, handling and storage. The hulls can serve easily as animal feed or in some industrial applications, but need to be removed for human food products. Cultivation of ancient wheats has survived on a limited scale in Italy, Switzerland, Germany and Poland. During the past two decades the conservation and green movements in Europe have promoted cultivation of ancient wheats to preserve genetic resources. reference book At present most of the wheats grown are hybrids which have been created from " ancient wheats " over the past 100 to 150 years. The process of domestication and breeding of the ancient grains may have produced varieties of wheat with particular characters, i.e, high yielding and better disease resistance. However, these hybrids may lack some of the other unique properties of the ancestral wheats. The plant characteristics of these ancestral wheats and related species are conditioned by genes on sets of seven chromosomes. Multiple sets of these origin seven chromosomes produce new hybrids. The wild 14 chromosome species were first domesticated and later evolved into modern wheats. For example, einkorn is a diploid wheat containing 14 chromosome. Emmer and Kamut/Khorasan (durum relative) are tetraploid wheats having 28 chromosome, and spelt (bread wheat ancestor) is a hexaploid wheat with 42 chromosome. Trends in organic agriculture and consumption of health food products have led to renewed interest in hulled wheat species. Spelt, for example, is found to perform well in low input systems and holds promise for the organic grain food market. In addition, it is believed that spelt wheat products are more tolerable and therapeutic than common wheat products as suggested by consumer testimonials. Ancient wheats also were used in alternative and folk medicine for the treatment of a wide range of health conditions such as ulcerous colitis, elevated serum cholesterol, hypertesion, diabetes, rheumatoid arthritis, depression and cancer. Current Canadian Research1 is evaluating organic spelt and other ancient wheat food products to learn more about their nutritional and health benefits. The relationship between diet and health has become well documented. Some of the ancient wheats have a unique composition of secondary components or minor compounds such as carotenoids which may have potential as functional food ingredients. For instance, einkorn was found to contain significantly high level of lutein compared to other wheat species. Lutein is the major yellow pigment in wheat grains, and the elevated level of lutein in einkorn wheat may pave the way for the development of function wheat market. Lutein is found to reduce the risk of age-related macular degeneration (AMD) and cataracts and provides protection against heart disease and cancer. In North America, the daily intake of lutein (1.5-2.0 mg) is below the suggested level (6 mg) and is declining due to a decrease in the consumption of the dark green vegetables, the main source of lutein. This indicates a need for the development of other dietary lutein diets. In general, ancient wheats represent a rich source of genetic diversity for improvement of agronomic and grain characteristics of modern pasta and bread wheats. These species also may offer unique nutritional, sensory and functional properties that could expand their uses into a wide range of regular and speciality food products such as organic foods, functional foods, multi-grain foods, nutty flavoured wheat foods, etc. Research is needed to explore more about nutritional and health properties of ancient grains. For more information: Specialty Grains for Food and Feed published by the American Association of Cereal Chemists contains useful information about some of the ancient grains regarding their nutritional and health aspects.1 Abdel-Aal, E-S.

Guest guest Posted March 10, 2007 Report Share Posted March 10, 2007 just to add to the whole conspiracy paranoia --- but i also heard that Iraq had a grain storage facility which housed some of the oldest known grain-types of wheat in the world and that strangely, although this facility was nowhere near any fighting or hot spots, it got mysteriously bombed destroying thousands of these last remaining original grains. i don't have any concrete link for people to look at - this was something that i heard in conversation, that's all. i wonder sometimes though with this constant desire to pollute our food and water sources - WHAT IS GOING ON??????????? and how can we, how can we stop this. surely we must be able to fight it? we read and read about how the cows are dying after eating GM cotton, about how birds in Argentina are dropping dead in the middle of the sky from the GM soya --- people are getting sicker and sicker with the same sort of symptoms of intestinal poisoning, lethargy, immune suppressed symptoms and still, still, still governments are not banning this lethal and unnecessary food. WHY NOT????? why not? why not. i cannot understand it. i simply cannot understand it - there is no need to change our food - it is perfect as it is, humans have adapted to this food source over millions of years. when SO FEW benefit from this introduction of GM foods, when such a tiny minority of already exceedingly wealthy people are to make a profit from it. when it gives companies such as Monsanto control over seeds and farmers all over the world - who could accept this? who could accept this monstrous monopoly, this hideous disregard for nature and life, this compulsive obsession with money above all - to the point of destruction of all food stuffs (which we ALL rely on to survive, we none of us can live without food or water - not ONE of us) and peoples. how is this continuing to be perpertrated. why do the governments not stop it? how can this be? for whom are our governments working? the people who elect them and whom they claim to represent??? or Monsanto and the interests of a small elite group of billionnaire investors and power-mongers. i cannot comprehend it. if you write to your health minister - you get a standard letter back of basically refusing to answer your question. how to STOP it. how to STOP IT. and on another note, Monsanto (i believe) are in the process of re-branding as " Serona " or something similar, i can't remember off-hand i will have to check. Please be aware of this and if buying pesticides or similar products don't be fooled by the new title. well, i suppose we must all try to do what we can --- but the difficulty is, for me, WHAT CAN WE DO? there must be something (other than direct action and pulling up fields of GM crops - BUT maybe that is the only way). i always still expect the people in power to have a good conscience and do the right thing but perhaps that is naive. , " JoAnn Guest " <angelprincessjo wrote: > > Ancient Wheats and New Perspective > by Dr. Elsayed Abdel-Aal > ~ January 2005 No.187 ~ > > Wheat has been used as a food grain since the last Stone Age.
