The Science Behind Sugar Rush: How Your Brain and Body React to Excess Sugar



What Is a Sugar Rush and How to Deal With It?




Have you ever felt a sudden burst of energy and happiness after eating a piece of cake, a candy bar, or a soda? Many people call this feeling a "sugar rush" and believe that it is caused by consuming too much sugar at once. However, is there any truth behind this popular notion? Or is it just a myth?

The Science Behind Sugar




Sugar is a type of carbohydrate that provides energy for the body and brain. When we eat foods that contain sugar, such as fruits, honey, milk, or processed foods with added sugar, our digestive system breaks them down into glucose, which is then absorbed into the bloodstream. Glucose is then transported to various organs and tissues, where it is used as fuel or stored for later use.


One of the main organs that uses glucose is the brain. The brain needs a constant supply of glucose to function properly and maintain cognitive abilities, such as memory, attention, learning, and mood. Glucose also stimulates the release of neurotransmitters, which are chemical messengers that communicate between brain cells and affect our emotions and behavior.


The Myth of the Sugar Rush




Based on this information, it may seem logical to assume that eating more sugar would give us more energy and make us happier. However, this is not what happens in reality. In fact, several studies have shown that there is no evidence that sugar intake causes hyperactivity or mood swings in healthy adults or children.


For example, a meta-analysis published in 2019 reviewed 31 randomized controlled trials that examined the effects of acute sugar consumption on mood in healthy individuals. The researchers found no significant changes in alertness, depression, calmness, fatigue, confusion, tension, or anger at any time point after eating sugar. On the contrary, they found that sugar consumption was associated with decreased alertness and increased fatigue within the first hour after ingestion.


Another study published in 1994 tested the effects of sugar on children's behavior in a double-blind experiment. The researchers gave children either a drink containing sugar or a drink containing an artificial sweetener and observed their behavior in various settings. They found no differences in activity level, aggression, attention span, or learning ability between the two groups.

The Reasons Behind the Sugar Rush Feeling




If sugar does not cause a sugar rush, then why do some people feel like they have one after eating sweets? There are several possible explanations for this phenomenon.


  • One reason could be psychological. Some people may expect to feel more energetic and happy after eating sugar because they have learned to associate sweets with positive emotions and rewards. This expectation may influence their perception of their own mood and behavior.



  • Another reason could be environmental. Often, we eat sweets during special occasions or social events, such as birthday parties, holidays, or gatherings with friends and family. These situations may create excitement and stimulation that can make us feel more lively and cheerful.



  • A third reason could be physiological. Eating too much sugar can cause fluctuations in blood glucose levels, which can affect how we feel physically and mentally. When we eat sugar, our blood glucose level rises quickly, which triggers the release of insulin from the pancreas. Insulin helps lower blood glucose level by moving it into cells or storing it as glycogen or fat. However, if we eat more sugar than our body can handle at once, our blood glucose level may drop too low after insulin does its job. This can cause symptoms such as hunger, weakness, shakiness, dizziness, irritability, anxiety, or headache.



The Tips to Avoid or Cope The Tips to Avoid or Cope With a Sugar Rush




Although a sugar rush is not a real phenomenon, it can still be unpleasant to feel the effects of eating too much sugar. Here are some tips on how to avoid or cope with a sugar rush:


  • Limit your intake of added sugar. The American Heart Association recommends no more than 9 teaspoons (36 grams) of added sugar per day for men and no more than 6 teaspoons (25 grams) of added sugar per day for women. Added sugar is any sugar that is not naturally present in foods, such as table sugar, honey, syrups, or fruit juices. You can check the nutrition labels of packaged foods and beverages to see how much added sugar they contain.



  • Choose natural sources of sugar. Fruits, vegetables, dairy products, and whole grains contain natural sugars that are accompanied by fiber, vitamins, minerals, and antioxidants. These nutrients can help slow down the absorption of sugar and prevent blood glucose spikes and crashes. They can also make you feel fuller and more satisfied.



  • Pair sugar with protein and fat. Protein and fat can also help slow down the digestion and absorption of sugar and keep your blood glucose level stable. They can also provide energy and satiety. For example, instead of eating a candy bar by itself, you can have a handful of nuts or a slice of cheese with it.



  • Drink plenty of water. Water can help flush out excess sugar from your system and prevent dehydration, which can worsen the symptoms of a sugar rush. Water can also help you feel more alert and refreshed.



  • Exercise moderately. Exercise can help burn off some of the excess glucose in your blood and muscles and improve your mood and energy level. However, avoid exercising too intensely or for too long, as this can cause your blood glucose level to drop too low and make you feel worse.



Conclusion




A sugar rush is a common belief that eating too much sugar can cause hyperactivity and mood swings. However, there is no scientific evidence to support this claim. In fact, eating sugar may have the opposite effect of making you feel less alert and more tired. The feeling of a sugar rush may be due to psychological, environmental, or physiological factors that are not directly related to sugar intake. To avoid or cope with a sugar rush, you can limit your intake of added sugar, choose natural sources of sugar, pair sugar with protein and fat, drink plenty of water, and exercise moderately.
