Women's staple food is too refined to interfere with sleep.

Original title: Women's Staples Eat Too Fine, Interfere with Sleep
A new study from Columbia University School of Medicine has found that eating refined carbohydrates may be a major cause of insomnia in adults.
team selected more than 50,000 post-menotinal female participants from the Women's Health Initiative project to keep a complete diet diary. The researchers looked at the sleep quality of women who ate foods with higher sugar index, based on the hypothesis that a sudden rise in blood sugar after eating refined carbohydrates was more likely to trigger insomnia. The results showed that post-menoanth women who ate large amounts of refined carbohydrates, especially added sugars, were more likely to develop insomnia. In contrast, women with higher levels of vegetables, dietary fiber and natural fruits(not fruit juices) had lower rates of insomnia. The study was published in the American Journal of Clinical Nutrition.
that different types and quantities of carbohydrate can raise blood sugar levels to varying degrees. Refined carbohydrates (e.g. white bread, sweet bread, white rice and carbonated sodas) have a high sugar index, which can lead to a sharp increase in blood sugar levels. When blood sugar rises rapidly, the body reacts by releasing insulin, which causes blood sugar to drop, which causes an increase in the release of hormones such as adrenaline and cortisol, which interferes with sleep. Since blood sugar levels rise rapidly after most adults eat refined carbohydrates, the researchers say this conclusion is not limited to post-menotinal women. New research concludes that the use of dietary interventions to treat insomnia is expected to be a viable method.
