Have you ever wondered if sugar could be as addictive as cocaine? It might sound surprising, but some studies suggest that sugar, the sweet stuff in cakes, sodas, and chocolates, might be harder to give up than you think.
In 2007, scientists at the University of Bordeaux conducted an interesting experiment with rats. They set up cages with two levers. One lever gave the rats a dose of cocaine, while the other let them drink sugar water for 20 seconds. After trying both options, a whopping 94% of the rats chose the sugar water over cocaine, even when the cocaine dose was increased. This shows just how powerful the lure of sugar can be.
When scientists look at the brains of people addicted to food and those addicted to cocaine, they find something fascinating. Both groups show a big spike in dopamine, a feel-good chemical, when they crave something. However, the actual satisfaction from consuming the food or drug is much lower. This means that people often crave sugar more than they actually enjoy eating it.
From an evolutionary standpoint, cravings make sense. Our ancestors needed to enjoy eating high-calorie foods like wild boar to survive. If they didn’t crave these foods, they might not eat enough and could starve. Back then, food was scarce, so craving sugar and fat was beneficial. Today, however, sugar is everywhere, from bread to candy, making it easy to consume too much.
In today’s world, sugary and high-calorie foods are all around us. This constant exposure can mess with our hormones. Unlike our ancestors, who had to deal with feast or famine, we can eat all the time. This leads to more insulin production, which stores food in our fat cells, and prevents our bodies from burning fat, causing weight gain.
So, what can you do to reduce sugar intake? Start by cutting down on processed foods, which often have lots of sugar. If a food has a long list of ingredients, it’s likely processed. Instead, try to eat whole foods, which are the ingredients themselves.
Consider eating like our ancestors. For snacks, nuts are a healthy choice. If you crave something sweet, try fruit. While fruit has sugar, it also contains fiber, which helps your body process the sugar more slowly and keeps your hormones balanced.
If you’re up for a challenge, try cutting out all sugars for a couple of weeks. You might find that your sugar cravings decrease, and you won’t believe how you ever managed to eat a whole box of donuts in one go!

Imagine you’re a scientist conducting the rat study mentioned in the article. Create a simple simulation using everyday objects to represent the levers and rewards. Discuss with your classmates why the rats might have chosen sugar over cocaine and what this tells us about sugar’s addictive properties.
In groups, role-play the process of dopamine release in the brain when consuming sugar. Assign roles such as neurons, dopamine, and receptors. Act out how dopamine is released and how it affects cravings and satisfaction. Reflect on how this process compares to drug addiction.
Go on a scavenger hunt in your kitchen or school cafeteria to find foods with hidden sugars. Make a list of these foods and research healthier alternatives. Share your findings with the class and discuss how you can make better food choices.
Design a one-day meal plan that minimizes sugar intake, focusing on whole foods. Include breakfast, lunch, dinner, and snacks. Present your meal plan to the class and explain how it aligns with the advice given in the article about reducing sugar consumption.
Keep a food diary for a week, noting down everything you eat and drink. Highlight items that contain added sugars. At the end of the week, analyze your diary and set goals for reducing sugar intake. Share your experience and strategies with your classmates.

[Music] What’s more addictive: cocaine or sugar? You might think that the sweet stuff found in cakes, breads, sodas, and chocolate would be easier to give up than a substance so dangerously addictive that it’s illegal. However, you might be surprised.
In 2007, researchers at the University of Bordeaux conducted a study where they equipped rat cages with two levers. One lever provided the rats with an intravenous hit of cocaine, while the other allowed them 20 seconds to drink sugar water. The rats were allowed to sample each lever twice to see their preferences. Once the tests began, 94% of the rats chose the sugar-sweetened water. Interestingly, the rats still preferred the sweetened water even when the researchers gradually increased the cocaine dose.
When comparing the brains of food addicts to those of cocaine addicts, the similarities are striking. MRI scans of brain activity reveal a massive spike in dopamine upon initial craving, high levels of anticipation, but low levels of satisfaction upon consumption. Essentially, food addicts crave sugar more than they actually enjoy eating it.
This presents a problem: we enjoy high-calorie foods and drugs because consuming them releases feel-good chemicals in the brain, like dopamine and endorphins. However, it takes more and more of the stimulus to achieve the same level of pleasure, leading to increased cravings.
From an evolutionary perspective, cravings make sense. If we hunted down a delicious wild boar and feasted upon it, we would derive pleasure from eating it. But if the cravings for that food never returned, we would risk starvation. In our modern world, however, it’s much more likely to have too much of something than too little. The brains of our ancestors craved sugar for a good reason: food was scarce in prehistoric times, and anything high in calories, like sugar or fat, was very rewarding.
Today, sugar and refined carbohydrates are ubiquitous, found in everything from bread to ready meals, pasta sauces, sodas, and candy. While the food landscape has changed, our brains have not. We are designed to crave high-calorie foods, but the problem is that they are everywhere. Imagine the issues if cocaine were this accessible.
This constant exposure to high-calorie, high-sugar foods disrupts our hormones. Unlike our ancestors, whose eating schedule was one of feast or famine, we can graze constantly, which throws our hormones out of balance. We produce more insulin, which leads to food being stored in our fat cells. Additionally, constant eating prevents our bodies from entering a fat-burning state, contributing to weight gain.
So, what can you do to cut down on sugar? The most important step is to reduce processed foods, which often contain high amounts of sugar as it’s the easiest and cheapest way to produce something palatable. If a food has a long list of ingredients, it’s likely processed. Real foods don’t have ingredients; they are the ingredients.
Try to eat like our ancestors. If you need a snack, nuts are a healthy option. If you still struggle with sugar cravings, fruit can be a good alternative. While fruit does contain sugar, it also has natural fiber, which helps prevent the sugar from being metabolized too quickly and disrupting your hormones.
If you’re feeling adventurous, you can try going cold turkey by cutting out all sugars for a couple of weeks. You may find that your cravings for sugar diminish significantly, and you’ll be surprised at how you could ever finish a box of donuts in one sitting.
