An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance one standard deviation below the median, and so on. Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number by either procedure.
Grains are often the seeds of certain plants. The seed, or kernel, is made up of three parts: the bran, the endosperm and the germ-all of which contain valuable nutrients that play an important role in your diet.
Most refined grains are enriched, which means that some of the B vitamins and iron are added back after processing. Fiber, however, is not added back to enriched grains. Some examples of enriched grains are wheat flour, enriched bread and white rice. Many whole grains are good or excellent sources of dietary fiber.
