For Better Sleep, Limit Your Intake Of Sweets And Carbs

New research by scientists at Columbia University's School of Therapy and Surgery shows that people who consume large amounts of refined carbohydrates (including sugar) are more likely to suffer from insomnia. And vice versa, people who have a diet that includes lots of fiber-rich vegetables and fruits have less sleep problems.

During the study, experts collected data from more than 50,000 people participating in the US Women's Health Protection Initiative. The analysis showed a clear correlation between dietary composition and sleep quality in women, who were responsible for keeping a food diary in the framework of the initiative.

Sugar Is The Cause Of Insomnia

Highly refined or refined carbohydrates found in sugar, white bread, white rice and carbonated beverages, have a high glycemic index and cause a rapid rise in blood sugar.

The study's lead author, Dr. James Gangwish, an associate professor at Columbia University, explained that in response to a sharp rise in blood sugar, the body responds by producing large amounts of insulin. This leads to a rapid drop in sugar levels, which can trigger the release of hormones like adrenaline and cortisol, and, in turn, can disrupt sleep.
"Whole fruits also contain carbohydrates, but the fiber in them slows down the rate of absorption, which helps prevent a spike in blood glucose. This shows that the cause of insomnia in women is due to food. Processing, containing a larger amount of refined sugar. Under normal conditions, such products are not found in nature."

Mr. Gangwish concluded.
