Original title: Cop: Older women prevent insomnia eat less sugar and white bread
some older women will face insomnia. Sugar and refined carbohydrates, such as white bread, are a major cause of insomnia in older women, according to a study published recently in the American Journal of Clinical Nutrition. Older women who regularly eat these foods may be more likely to lose sleep than their peers who do not.
Columbia University and others spent three years tracking the diet and sleep of more than 50,000 women in their 60s. The researchers calculated their dietary glycemic index. A higher glycemic index means that people consume more refined carbohydrates, such as white bread, sugar and sugary soda.
the study, women with the highest glycemic index reported 11 percent higher rates of insomnia than women with the lowest glycemic index. At the end of the three-year follow-up period, women with the highest glycemic index were also 16 percent more likely to have new insomnia than women with the lowest glycemic index.
researchers say that when blood sugar rises rapidly, the body reacts by releasing insulin, which in turn causes the body to release hormones such as epinephrine and cortisol, which interfere with sleep.
study shows the importance of diet for insomniacs, the researchers said. In addition to weight control, avoiding insomnia is also a reason to avoid refined carbohydrates such as sweets. In addition, the study found that women who ate large amounts of fiber-rich foods, such as vegetables and fruits, rather than drinking fruit juice, had fewer insomnia.
