High Possibility Of Short-Sightedness from High Diet of Breads in Childhood

Research results say that eating too much bread in childhood may cause short-sightedness.

In the latest issue of New Scientist, Britain’s science magazine, Loren Cordain, a biologist at Colorado State University, and Jennie Brand Miller, a nutrition scientist at the University of Sydney, reported that diets high in refined starches such as breads and cereals may cause short-sightedness. According to Cordain’s team, refined starches digest fast and in response to this rapid digestion, insulin level rises, reducing levels of insulin-like binding protein-3, which controls eyeball growth in childhood. Cordain explained that decrease of protein-3 can cause abnormal lengthening of eyeballs, and therefore, cause short-sightedness.

Cordain also points out that some scientists insist that short-sightedness occurs because children read books too closely, but it is insufficient to explain why in countries that do not have western diets but have western education, rate of myopia is lower.

For example, in the islands of Vanuatu, children have 8 hours of compulsory education everyday, but the rate of myopia is only 2 Per Cent. The reason is that they mainly eat fish and coconuts, rather than white bread and cereals.
