Introduction to Carbohydrates
What Are Carbohydrates?
Carbohydrates are an essential part of our diet. Most importantly, they provide the energy for the most obvious functions of our body, such as moving or thinking, but also for the ‘background’ functions that most of the time we do not even notice. During digestion, carbohydrates that consist of more than one sugar get broken down into their [monosaccharides](https://chem.libretexts.org/Courses/American_River_College/CHEM_309%3A_Applied_Chemistry_for_the_Health_Sciences/07%3A_Carbohydrates_-_An_Introduction/7.01%3A_Introduction_to_Carbohydrates) by digestive enzymes.
Types of Carbohydrates
Carbohydrates come in different forms, ranging from sugars over starch to dietary fibre, and are present in many foods we eat. Simple carbohydrates – those with one or two sugar units – are also simply known as sugars. Examples are:
- Monosaccharides
- Disaccharides
- Polyols
Why Carbs Matter
Carbohydrates are vital at every stage of life. They’re the body’s primary source of energy and the brain’s preferred energy source. When your body doesn’t get adequate carbohydrates, it looks for another energy source, breaking down fats and proteins instead. This can lead to a lack of energy and other health issues.
Carbohydrates are one of the three macronutrients in our diet, and as such essential for the proper functioning of the body. They come in different forms, like sugars and dietary fibre, and in many different foods, such as whole grains, fruit and vegetables.
Carbohydrates and Energy
How Carbs Provide Energy
Carbohydrates, also known as carbs, are vital at every stage of life. They’re the body’s primary source of energy and the brain’s preferred energy source. Carbs are broken down by the body into glucose – a type of sugar. Glucose is used as fuel by your body’s cells, tissues, and organs. When your body doesn’t get adequate carbohydrates, it looks for another energy source, breaking down fats and proteins instead. This process is less efficient and can lead to fatigue.
Carbs in Everyday Foods
Carbohydrates are found in a variety of foods that we consume daily. Here are some common sources:
- Fruits
- Vegetables
- Grains
- Dairy products
Each gram of carbohydrates provides 4 calories. This makes them an essential part of our diet, especially for those who are physically active. For instance, Mike Phan is a running coach in York who emphasizes the importance of carbs in his training programs.
Balancing Carbs in Your Diet
Balancing your carbohydrate intake is crucial for maintaining energy levels and overall health. Here are some tips:
- Use a BMR calculator to determine your daily caloric needs.
- Include a mix of simple and complex carbs in your diet.
- Pay attention to portion sizes to avoid overconsumption.
- Stay hydrated to help your body process carbs efficiently.
Carbohydrates are stored in the muscles and liver as glycogen. This storage helps delay the onset of fatigue and aids in muscular endurance.
Incorporating the right amount of carbohydrates can make a significant difference, especially for athletes. For example, in marathon training, nutrition and hydration strategies are crucial, emphasizing carb intake, fueling, and hydration balance.
Health Benefits of Carbohydrates
Carbs and Gut Health
Carbohydrates, especially dietary fiber, play a crucial role in maintaining good digestive health. Fiber helps to keep things moving smoothly in your digestive tract and can prevent issues like constipation. Foods high in fiber, such as whole grains, fruits, and vegetables, are essential for a healthy gut.
Carbs and the Immune System
Believe it or not, carbs can also support your immune system. Certain types of carbohydrates, like those found in fruits and vegetables, are packed with vitamins and minerals that help keep your immune system strong. Balanced diet is key here, as it ensures you’re getting a variety of nutrients to support overall health.
Carbs and Disease Prevention
Including the right types of carbs in your diet can help lower your risk of chronic diseases. For instance, whole grains and fiber-rich foods can reduce the risk of heart disease and type 2 diabetes. It’s all about making smart choices and avoiding refined carbs and added sugars.
Carbohydrates are essential for providing the body with energy and helping it function optimally. People may have varying requirements for carbohydrates according to their lifestyle, weight, and activity level.
Mike Phan is a personal trainer in York who emphasizes the importance of a balanced diet in his weight loss service York. He often advises clients at MPRS Personal Training in York to focus on whole, unprocessed carbs for better health outcomes.
Carbohydrates in Modern Diets
In recent decades—and with the rise of diets like ketogenic, paleo, and Atkins—there’s been growing confusion about one nutrient’s role and importance in particular: carbohydrates. Yet, this macronutrient remains an important part of an overall balanced diet and is necessary for good health. Understanding the role of carbohydrates – and the foods they’re found in – can help you follow a nutritious, balanced diet.
Low-Carb Diets Explained
Many people have turned to low-carb diets, such as the keto diet, for their potential health benefits and weight loss. However, some types of carbohydrates – including whole grains and dietary fiber – have substantial health benefits. Carbohydrates are essential for providing the body with energy and helping it function optimally. People may have varying requirements for carbohydrates according to their lifestyle, weight, and activity level.
Misconceptions About Carbs
There are three types of carbohydrates — simple carbs, starches, and fiber. Many whole foods contain a mix. Simple carbohydrates are made from one or two sugar molecules and are quickly digested. Starches and fibers, on the other hand, are more complex and take longer to break down. This difference is crucial because it affects how quickly foods raise blood sugar levels. The glycemic index (GI) ranks how quickly a food raises blood sugar levels on a scale of 0 to 100.
Finding the Right Balance
Healthful carbohydrates include fruit, vegetables, legumes, whole grains, and some cereals. These foods contain essential vitamins, minerals, fiber, and key phytonutrients. The Mediterranean diet, for example, has a moderate amount of carbohydrates from mostly whole food sources plus some animal or fish protein. This diet relates to a lower risk of developing T2DM. Most people can ensure that they eat a healthful diet by including complex carbohydrates and limiting their intake of refined carbohydrates. Being thoughtful about carbohydrate choices can help give a person a good blood glucose balance and limit the risk of associated health conditions.

Conclusion
No matter where you stand on the carbohydrate debate, it’s clear that carbs play a crucial role in our bodies. They are our primary source of energy, fueling everything from our daily movements to complex brain functions. Beyond just providing energy, carbohydrates are involved in various essential processes, including immune function, disease prevention, and even reproduction. While some diets may suggest cutting them out, understanding their importance can help you make more informed dietary choices. So, next time you think about skipping that slice of bread, remember that carbs are not the enemy—they’re an essential part of a balanced diet.
