The brain knows when it needs sugar and can't be fooled by artificial sweeteners, even if it is sweeter than real sugar.
A new study has found that the brain can differentiate between real
and artificial sugar. What's worse? Eating food with artificial
sweeteners will only increase cravings for sugary treats later.
The brain's reward system is highly activated when the body receives a
sugary solution rather than artificial sweeteners. Researchers at Yale
University School of Medicine USA, believe that the research might
explain the reason behind increasing obesity rates despite artificial
sweeteners existing for years now.
Food seasoned with artificial sweeteners is extremely popular. In the
U.S., about 30 percent of people eat stuff that has sugar substitutes.
Previously, Yale Journal of Biology and Medicine, had published an article about artificial sweeteners' effect on the body. Another recent study had found that drinking a can of diet soda can increase the risk of diabetes.
Researchers in the study argue that eating food containing artificial
sweeteners, especially while you are hungry, will make you consume more
sugar later.
In the study, researchers looked at specific brain signals that are
associated with determining the difference between sugar and artificial
sweeteners. These signals regulate the release of dopamine levels.
Dopamine is
a chemical messenger and affects processes that control behavior,
emotional response and more importantly the ability to feel pleasure.
The chemical plays a major role in addiction.
The study was conducted on a group of mice and researchers looked for
specific brain circuits while the mice were fed sugar or artificial
sweeteners.
"According to the data, when we apply substances that interfere with a
critical step of the 'sugar-to-energy pathway', the interest of the
animals in consuming artificial sweetener decreases significantly, along
with important reductions in brain dopamine levels," said Ivan de
Araujo, who led the study at Yale University School of Medicine USA.
"This is verified by the fact that when hungry mice - who thus have
low sugar levels - are given a choice between artificial sweeteners and
sugars, they are more likely to completely switch their preferences
towards sugars even if the artificial sweetener is much sweeter than the
sugar solution," de Araujo said in a news release.
So, can there be a sugar substitute that can help people reduce weight without punishing the taste buds?
"The results suggest that a 'happy medium' could be a solution;
combining sweeteners with minimal amounts of sugar so that energy
metabolism doesn't drop, while caloric intake is kept to a minimum,"
Araujo said.
The study is published in the Journal of Physiology.
