Experts Agree: Sugar Might Be as Addictive as Cocaine

We reward children with it over the holidays or for a job well done in school. And we reward ourselves with it after a particularly stressful day or to celebrate a birthday or a special success.

We add sugar to our coffee, bake it into our favorite treats, and spoon it over our breakfast. We love the sweet stuff. We crave it. But are we addicted to it?

There’s an increasing body of research that tells us excess sugar could be as addictive as some street drugs and have similar effects on the brain.

“Addiction is a strong word,” says Dr. Alan Greene, a children’s health and wellness expert and the author of books like “Raising Baby Green” and “Feeding Baby Green.”

“In medicine we use ‘addiction’ to describe a tragic situation where someone’s brain chemistry has been altered to compel them to repeat a substance or activity despite harmful consequences. This is very different than the casual use of ‘addiction’ (‘I’m addicted to “Game of Thrones!”’).”

In Greene’s opinion, evidence is mounting that too much added sugar could lead to true addiction.

What is an addiction?

Eating sugar releases opioids and dopamine in our bodies. This is the link between added sugar and addictive behavior.

Dopamine is a neurotransmitter that is a key part of the “reward circuit” associated with addictive behavior. When a certain behavior causes an excess release of dopamine, you feel a pleasurable “high” that you are inclined to re-experience, and so repeat the behavior.

As you repeat that behavior more and more, your brain adjusts to release less dopamine. The only way to feel the same “high” as before is to repeat the behavior in increasing amounts and frequency. This is known as substance misuse.

Cassie Bjork, RD, LD, founder of Healthy Simple Life, states that sugar can be even more addicting than cocaine.

“Sugar activates the opiate receptorsTrusted Source in our brain and affects the reward center, which leads to compulsive behavior, despite the negative consequences like weight gain, headaches, hormone imbalances, and more.”

Bjork adds, “Every time we eat sweets, we are reinforcing those neuropathways, causing the brain to become increasingly hardwired to crave sugar, building up a tolerance like any other drug.”

Indeed, research on rats from Connecticut College has shown that Oreo cookies activate more neurons in the pleasure center of the rats’ brains than cocaine does (and just like humans, the rats would eat the filling first).

And a 2008 Princeton studyTrusted Source found that rats may become dependent on sugar, and that this dependency could be related to several aspects of addiction: cravings, binging, and withdrawal.

Researchers in FranceTrusted Source agree that the casual link between sugar and illegal drugs doesn’t just make for dramatic headlines. Not only is there truth to it, but also they determined the rewards experienced by the brain after consuming sugar are even “more rewarding and attractive” than the effects of cocaine.

“Stories in the press about Oreos being more addictive than cocaine may have been overstated,” admits Greene, “but we should not take lightly the power of added sugar to lure us again and again, and to rob us of our health.”

He adds, “Medical addiction changes brain chemistry to cause binging, craving, withdrawal symptoms, and sensitization.”

Sugar is also much more prevalent, available, and socially acceptable than amphetamines or alcohol, and so harder to avoid.

But whether sugar is more addictive than cocaine, researchers and nutritionists suggest that sugar has addictive propertiesTrusted Source, and we need to be getting less of it.

“The drug analogy is always a tough one because, unlike drugs, food is necessary for survival,” says Andy Bellatti, MS, RD, strategic director of Dietitians for Professional Integrity.

“That said, there is research demonstrating that sugar can stimulate the brain’s reward processing center in a manner that mimics what we see with some recreational drugs.”

Bellatti adds, “In certain individuals with certain predispositions, this could manifest as an addiction to sugary foods.”

What is added sugar?

The World Health Organization (WHO)Trusted Source has been cautioning people to reduce their intake of “free sugars” to less than 10 percent of daily calories since 1989. The organization says that doing so can lower the risk of becoming obese or overweight, or experiencing tooth decay.

“Free sugars” include both the sugars naturally found in honey and fruit juice, and sugar added to food and drinks. On food labels, added sugars include words such as glucose, corn syrup, brown sugar, dextrose, maltose, and sucrose, as well as many others.

In 2015, WHO further suggested reducing free sugar daily intake to less than 5 percent of calories, about 6 teaspoons. In the United States, added sugars accountTrusted Source for 14 percent of the average person’s daily calorie intake.

Most of this comes from beveragesTrusted Source, including energy drinks, alcoholic drinks, soda, fruit drinks, and sweetened coffee and teas.

Other common sources are snacks. These don’t just include the obvious, like brownies, cookies, doughnuts, and ice cream. You can also find large quantities of added sugar in bread, salad dressing, granola bars, and even fat-free yogurt.

In fact, one surveyTrusted Source found that high-calorie sweeteners are in over 95 percent of granola bars, cereals, and sugar-sweetened beverages, most often in the form of corn syrup, sorghum, and cane sugar.

The Office of Disease Prevention and Health Promotion’s 2015-2020 Dietary GuidelinesTrusted Source suggest cutting consumption of added sugars to less than 10 percent of calories per day.

To help consumers, the Food and Drug Administration has developed a new food labelTrusted Source that lists added sugars separately, which manufacturers are required to use (though some smaller manufacturers have until 2021 to comply).

“You need food to survive, and I think it’s unrealistic to think you will be able to completely ‘quit’ sugar,” says Alex Caspero, MA, RD, a blogger, health coach.

“The problem is that we aren’t meant to enjoy sugars in such concentrated amounts.

“In nature, sugar is found surrounded by fiber, in sugar cane and fruits. It naturally comes in a container that produces a shorter blood sugar response and aids in fullness. Today’s sugars are refined and concentrated.”

Caspero adds, “The good news is that we can adapt our taste buds to accept less sugar. Reducing sugar, especially concentrated sugars, not only limits the amount of sugars ingested, but also makes less sweet foods seem sweeter.”

  1. Cane! Sugar! Cane! Sugar!
    And if you get hooked, baby, it’s nobody else’s fault, so don’t do it!

    Sad thing, it’s in so much eatable ‘food’ products – it’s hard to get away from it. Still – at the end of the day – it is (imo) better to ‘indulge’ in sugar products INSTEAD of the artificially sweetened ones. ***in moderation – of course
