Ankeny, Iowa, January 12, 2016— If you have trouble sleeping, or suffer from insomnia, you may want to add soyfoods to your daily diet. New results from the first population study to examine the relationship between soy and sleep habits indicates that soyfoods offer striking benefits. Soyfoods are uniquely rich sources of isoflavones, which are naturally occurring compounds classified as plant estrogens. The hormone estrogen tends to promote better sleep, both in terms of quality and duration.
A recent population study involving over 1,000 Japanese adults interviewed each participant to determine the amount of soy and isoflavones consumed and answered questions about how long and how well they slept. Among the group of participants, 13 percent reported regular sleep duration (7 to 8 hours a day) and 56 percent reported sufficient sleep quality. After adjusting for potential confounding factors, individuals in the group with the highest soy intake were almost twice as likely to sleep at least 7 to 8 hours, and about twice as likely to have better sleep quality. Those in the highest intake group consumed about two servings of soyfoods per day.
This study is good news for the millions of Americans who suffer from insomnia. According to survey data from the National Sleep Foundation, 48 percent of Americans say they have occasional insomnia, while 22 percent experience insomnia. Getting a good night’s sleep is a vital component of overall good health and can aid in maintaining a healthy weight. Sleep-deprived people tend to snack more at night, and also may crave higher-carbohydrate foods and larger portions.
In the U.S., popular soyfoods include tofu, soymik and edamame. The Soyfoods Council offers tips and ideas for enjoyable ways to consume soy.
