3 Ways to Eat, Sleep, and Gargle Your Way to a Better Brain
Stay sharp with these simple, scientifically proven techniques.
Eat: Less Fake Butter
Whether spread on a bagel or poured over movie popcorn, many butter substitutes and flavorings contain diacetyl-based chemicals, which may harm brain cells. Diacetyl promotes the protein clumps in the brain that mark Alzheimer’s disease, according to scientists at the University of Minnesota. Researcher Ashish Vartak, PhD, says that the study is preliminary, but he and his colleagues have started avoiding diacetyl by snacking on unflavored popcorn (they add salt or herbs). As for movie popcorn: “Ordering it without the added buttery liquid should reduce diacetyl exposure.”
Gargle: with Lemonade
A new study finds that sweet liquids boost resolve. The upside (for
dieters): You don’t have to swallow them. A University of Georgia study
has found that rinsing the mouth with sugar-sweetened lemonade helped
students perform better on tests of willpower. “Researchers used to
think the sugar had to enter the body to give you the energy for
self-control,” said University of Georgia psychology professor Leonard
Martin, coauthor of the study. But just holding the sugar in the mouth
the brain’s motivational centers to pay attention.
Sleep: Seven Hours
Getting too much sleep may be just as toxic to health as sleeping too
little. Researchers at Brigham and Women’s Hospital in Boston examined
more than 20 years of data from over 15,000 participants in the Nurse’s
Health Study and found that regularly sleeping two hours more or less
than seven hours a night was equivalent to two years of brain aging (as
measured on standard memory tests). The cognitive effects were also
present when the women’s sleep habits changed by two hours a night or
more as they got older.
