  What does Dyslexia(誦讀困難癥) have to do with food or nutrition? At the 56th Annual Conference of the International Dyslexia Association in Denver, Dr. Susan Koger, a professor from Willamette University in Oregon, presented a(n) 31 paper on the risks of environmental toxins(毒素)for developing learning differences, 32 dyslexia. Dr. Koger emphasized that humans are 33 during their lifetime to potential exposure 34 75,000 or more synthetic chemicals. More than 98 percent of families and 80 percent of pregnant women are 35 to these potential chemical toxins. The metabolites(代謝產(chǎn)物)or breakdown 36 of these chemicals can be identified in the urine(尿)of 82 percent of adults and 92 percent of children. Dr. Koger postulated that basically every human on the planet has detectable amounts of one or more of these toxins in their system 37 one time or another.

  It is our food supply that is of particular 38 , because these bio-toxins become concentrated as they make their way up the food chain. For instance, 891 pesticides have been 39 and used since 1941. Of these, 523 have been used 40 on our food or on feed stored for animals. Of those that are used in our food supply, 140 are 41 neuro-toxic(毒害神經(jīng)的)and can injure the brain. 42 , they were designed to kill insects and rodents. Only 12 of these 140 neurotoxins have been 43 for potential harm to the brain. No test for potential brain injury from these chemicals is 44 before they are released 45 use. The concern that Dr. Koger’s research 46 , by extrapolation(推斷), is that perhaps the older teachers may 47 part have been right, that the frequency of dyslexia in the student population was indeed once only two or three per-cent. The frequency now 48 , which is real at 17 to 25 percent, may be a reflection of the increased potential for damage to the developing brain of the fetus or newborn infant or toddler, perhaps 49 extending into the first few years of life, 50 by the toxic chemicals we have put into our environment. That is a frightening consideration.
