You’ve probably heard people say that carbohydrates, or carbs, aren’t good for you. But did you know that carbs are actually the main source of energy for your body? Let’s explore what happens to carbs when you eat them and how they help your body function.
Carbohydrates in our food come in three main types: sugars, starches, and dietary fiber. Sugars include things like lactose in milk, fructose in fruits like tangerines, and sucrose, which is table sugar. Starches and dietary fiber are made up of long chains of sugar molecules.
When you eat carbohydrates, your body starts breaking them down right away. Your saliva and stomach acid work together to break down the long chains of sugars into shorter ones. Once the food reaches your intestines, your pancreas releases enzymes that break down starches into pairs of sugar molecules. Dietary fiber, however, is different. Its bonds are stronger and can’t be broken down by our enzymes, so it passes through your digestive system intact, helping keep your digestive system healthy.
After starches are broken down, your small intestines release enzymes that further process the sugar molecules. These sugars are then absorbed into your bloodstream. The most important sugar molecule is glucose, which your cells use for energy. Your brain, in particular, uses about half of your body’s glucose. If you don’t have enough glucose, you might feel shaky, lightheaded, or confused.
What happens if you eat too much glucose? Your pancreas releases a hormone called insulin, which helps store the extra glucose for later use, like between meals or when you’re active. Some athletes eat more carbs to have extra energy stored for their sports activities.
Eating too much sugar can be bad for your brain health, possibly speeding up cell aging and leading to conditions like dementia. Luckily, for most people, the pancreas does a good job of keeping blood sugar levels in check. However, if you consistently eat more sugar than your body needs, it can lead to insulin resistance and diabetes.
If you’re worried about carbs and sugar, remember that food is fuel for your body, and that includes carbohydrates. Most experts suggest eating a balanced diet with a mix of carbohydrates, proteins, and fats. This way, your body and brain get the energy they need without overdoing it.
Explore different food items and categorize them into sugars, starches, and dietary fiber. Create a chart and discuss with your classmates why each food fits into its category. This will help you understand the types of carbohydrates and their sources.
Work in groups to create a model of the digestive system using household items. Simulate the breakdown of carbohydrates from the mouth to the intestines. This hands-on activity will help you visualize how carbs are digested and absorbed.
Conduct an experiment to see how glucose affects energy levels. Track your energy and concentration levels after consuming different types of carbohydrates. Share your findings with the class to understand the role of glucose in providing energy.
Participate in a role-play activity where you act out the process of insulin managing glucose levels in the body. This will help you grasp how the body regulates blood sugar and the importance of insulin in this process.
Create a balanced meal plan that includes a healthy mix of carbohydrates, proteins, and fats. Present your plan to the class and explain how it provides energy and supports overall health. This activity will reinforce the concept of balanced nutrition.

You’ve probably heard that carbohydrates are often viewed negatively, and many of us are looking for evidence that they can be beneficial. However, carbohydrates are actually the main fuel source for your body. So, what do carbohydrates do when they pass through your system?
Carbohydrates in our food can be categorized into three types: sugars, starches, and dietary fiber. Sugars, such as lactose, fructose, and sucrose, are found in foods like milk, tangerines, and table sugar. Starches and dietary fiber consist of long chains of sugars.
When we consume carbohydrates, our saliva and stomach acid break down these long sugar chains into shorter ones. Once the food reaches the intestines, the pancreas releases enzymes that further break down the starches into bonded pairs of sugar molecules. However, the bonds in dietary fiber are different; they are stronger and cannot be broken down by our enzymes, which means they pass through the digestive system intact, helping to maintain digestive health.
After starches are broken down, the small intestines release enzymes that further process the sugar molecules, which are then absorbed into the bloodstream. The most important of these sugar molecules is glucose, which all of your cells use for energy. Notably, your brain utilizes about half of your body’s glucose needs. A lack of glucose can lead to symptoms like shakiness, lightheadedness, and confusion.
But what happens if you consume too much glucose? When there is an excess, the pancreas releases insulin, which helps store glucose for later use, such as between meals or during physical activity. Some athletes increase their carbohydrate intake to have more energy stored for their performance.
However, excessive sugar intake can have negative effects on brain health, potentially contributing to cell aging and conditions like dementia. Fortunately, for most people, the pancreas effectively regulates blood sugar levels to prevent these issues. Yet, consistently consuming more sugar than the body requires can lead to insulin resistance and diabetes.
If you’re concerned about carbohydrates and their sugar content, it’s important to remember that food serves as fuel for the body, including carbohydrates. Most experts recommend consuming carbohydrates, proteins, and fats in moderation, ensuring that your body and brain receive the necessary fuel without overindulgence.

This version maintains the original message while removing any informal language and ensuring clarity.
Carbohydrates – Organic compounds made up of carbon, hydrogen, and oxygen that provide energy to living organisms. – Carbohydrates are an essential part of our diet, providing the energy needed for daily activities.
Sugars – Simple carbohydrates that are sweet-tasting and provide quick energy to the body. – Sugars are quickly absorbed into the bloodstream, giving a rapid boost of energy.
Starches – Complex carbohydrates that are made up of many sugar molecules linked together, providing a slow and steady release of energy. – Foods like potatoes and rice are rich in starches, which help sustain energy levels throughout the day.
Fiber – A type of carbohydrate that the body cannot digest, which helps regulate the body’s use of sugars and keeps hunger and blood sugar in check. – Eating foods high in fiber, such as fruits and vegetables, aids in digestion and helps maintain a healthy weight.
Glucose – A simple sugar that is an important energy source in living organisms and is a component of many carbohydrates. – After eating, carbohydrates are broken down into glucose, which is used by cells for energy.
Insulin – A hormone produced by the pancreas that regulates the amount of glucose in the blood. – Insulin helps cells absorb glucose from the bloodstream, lowering blood sugar levels.
Pancreas – A gland in the digestive system that produces insulin and other important enzymes and hormones that help break down foods. – The pancreas plays a crucial role in regulating blood sugar by releasing insulin.
Digestion – The process by which the body breaks down food into small molecules that can be absorbed and used for energy, growth, and cell repair. – Digestion begins in the mouth and continues in the stomach and intestines, where nutrients are absorbed into the bloodstream.
Energy – The ability to do work, which in biological terms is derived from the nutrients in food. – Our bodies convert the food we eat into energy, which powers all our activities and bodily functions.
Diet – The kinds of food that a person habitually eats, which can affect their health and energy levels. – Maintaining a balanced diet is important for providing the nutrients needed for growth and maintaining good health.
