Introduction
Carbohydrates are one of the most misunderstood nutrients in nutrition.
Over the years, low-carbohydrate diets and popular nutrition trends have led many people to believe that carbohydrates are unhealthy or should be avoided altogether. As a result, foods such as bread, rice and pasta are sometimes viewed as “bad” foods, regardless of their nutritional value.
In reality, carbohydrates are an important part of a balanced diet and serve as the body’s primary source of energy for many daily activities. They help fuel your brain, muscles and other organs while supporting normal body function.
Like all macronutrients, carbohydrates are not inherently good or bad. Instead, the quality, quantity and overall eating pattern matter far more than eliminating carbohydrates completely.
At 1% Movement, we believe healthy eating should be practical and evidence-based. Understanding what carbohydrates are and how they contribute to your health can help you make informed food choices without unnecessary fear or confusion.
In this article, you’ll learn what carbohydrates are, why they matter, the different types of carbohydrates and how they fit into a healthy eating pattern.
What Are Carbohydrates?
Carbohydrates are one of the three macronutrients your body needs in relatively large amounts.
When you eat carbohydrate-containing foods, your digestive system breaks most carbohydrates down into glucose, which your body uses as a source of energy.
Glucose is particularly important because it provides fuel for:
- The brain.
- The nervous system.
- Muscles during many forms of physical activity.
- Everyday body functions.
Any glucose that is not immediately needed may be stored as glycogen in the muscles and liver for later use or, when energy intake consistently exceeds your body’s needs, stored as body fat alongside excess energy from protein or fat.
This is why carbohydrates should be viewed as an important energy source rather than something to fear.
Why Carbohydrates Matter
Carbohydrates support many important functions throughout the body.
They help:
- Provide energy for daily activities.
- Fuel exercise and physical activity.
- Support normal brain function.
- Help maintain physical performance.
- Contribute fibre, vitamins and minerals through many carbohydrate-rich foods.
For people who enjoy walking, resistance training or other forms of exercise, carbohydrates play an important role in supporting movement and recovery.

Types of Carbohydrates
Not all carbohydrates are the same.
Carbohydrates can be grouped into several forms, but for everyday healthy eating, it’s useful to understand two broad categories.
Simple Carbohydrates
Simple carbohydrates are made up of one or two sugar molecules and are digested relatively quickly.
They occur naturally in foods such as:
- Fruit
- Milk
- Yoghurt
They are also found in foods and drinks with added sugars, including:
- Soft drinks
- Sweets
- Cakes
- Biscuits
- Confectionery
Foods containing naturally occurring sugars often provide important nutrients alongside carbohydrates, whereas foods high in added sugars may contribute more energy while providing fewer beneficial nutrients.
Complex Carbohydrates
Complex carbohydrates consist of longer chains of sugar molecules and are generally found in foods that also contain fibre, vitamins and minerals.
Examples include:
- Oats
- Brown rice
- Wholemeal bread
- Wholegrain pasta
- Beans
- Lentils
- Sweet potatoes
These foods often contribute to a balanced eating pattern because they provide sustained energy and additional nutrients.
Rather than avoiding carbohydrates altogether, many dietary guidelines encourage choosing wholegrain and higher-fibre carbohydrate sources more often.
Carbohydrates and Fibre
Many healthy carbohydrate-rich foods are also excellent sources of dietary fibre.
Fibre supports:
- Digestive health.
- Heart health.
- Feelings of fullness after meals.
- Healthy gut bacteria.
Foods rich in fibre include:
- Whole grains
- Fruits
- Vegetables
- Beans
- Lentils
- Nuts
- Seeds
We’ll explore fibre in much greater detail in our article Fibre Explained.
Do Carbohydrates Cause Weight Gain?
One of the most common nutrition myths is that carbohydrates automatically cause weight gain.
In reality, no single nutrient causes weight gain on its own.
Body weight is influenced by many factors, including:
- Overall energy intake.
- Physical activity.
- Sleep.
- Stress.
- Genetics.
- Long-term lifestyle habits.
Eating more energy than your body uses over time—regardless of whether that energy comes from carbohydrates, protein or fat—may contribute to weight gain.
This means carbohydrates can absolutely be part of a healthy eating pattern that supports healthy weight management.
Instead of avoiding carbohydrates completely, it is generally more beneficial to focus on choosing nutritious carbohydrate sources and eating appropriate portions.

Choosing Healthier Carbohydrate Sources
Not all carbohydrate-rich foods offer the same nutritional value.
Many foods that contain carbohydrates also provide important nutrients such as fibre, vitamins and minerals.
Examples of nutritious carbohydrate sources include:
- Wholegrain bread
- Brown rice
- Oats
- Quinoa
- Fruits
- Vegetables
- Beans
- Lentils
- Sweet potatoes
These foods often contribute to a balanced diet because they provide energy alongside other beneficial nutrients.
Highly processed foods containing large amounts of added sugars can still be enjoyed occasionally, but they are generally less nutrient-dense than whole or minimally processed carbohydrate foods.
Healthy eating isn’t about completely avoiding these foods—it’s about making nutritious choices more often while allowing flexibility.
How Carbohydrates Fit into a Balanced Meal
Carbohydrates work best when combined with other nutritious foods.
A balanced meal might include:
- A wholegrain carbohydrate source such as brown rice or wholemeal pasta.
- A source of protein such as fish, chicken, tofu or beans.
- Plenty of vegetables.
- A source of healthy fats, such as olive oil or avocado.
Combining different food groups creates meals that are satisfying, nutritious and enjoyable.

Common Carbohydrate Myths
Nutrition misinformation has caused many unnecessary fears about carbohydrates.
Let’s look at a few common myths.
Myth 1: Carbohydrates are unhealthy.
No.
Carbohydrates are one of the body’s primary energy sources and are an important part of a balanced eating pattern.
Myth 2: Bread and rice should be avoided.
Not necessarily.
Wholegrain breads, rice and other grain products can provide energy, fibre and important nutrients.
The overall quality of your diet is much more important than avoiding specific foods.
Myth 3: Fruit contains too much sugar.
Fruit contains naturally occurring sugars, but it also provides fibre, vitamins, minerals and many other beneficial nutrients.
For most people, fruit is an important part of a healthy diet.
Myth 4: Low-carbohydrate diets are the only way to lose weight.
No.
People can successfully manage their weight using many different eating patterns.
The most effective approach is usually one that is balanced, enjoyable and sustainable over the long term.
Frequently Asked Questions
Are carbohydrates bad for you?
No.
Carbohydrates are an essential source of energy and play an important role in supporting normal body function.
Choosing wholegrain and fibre-rich carbohydrate foods more often is generally recommended.
Should I stop eating carbohydrates if I want to lose weight?
Not necessarily.
Healthy weight management is influenced by overall eating patterns and lifestyle habits rather than eliminating one nutrient.
Many people successfully achieve and maintain a healthy weight while including carbohydrates as part of a balanced diet.
What’s the difference between simple and complex carbohydrates?
Simple carbohydrates are digested more quickly and include naturally occurring sugars found in foods like fruit and milk, as well as added sugars found in sweets and soft drinks.
Complex carbohydrates are generally found in foods such as whole grains, beans and vegetables, which often provide fibre and other important nutrients.
Is fruit a healthy source of carbohydrates?
Yes.
Fruit provides carbohydrates together with fibre, vitamins, minerals and many beneficial plant compounds.
For most people, fruit is an excellent addition to a balanced eating pattern.
Should athletes eat more carbohydrates?
People who perform regular physical activity or endurance exercise often have higher carbohydrate needs than individuals who are less active.
The exact amount varies depending on factors such as activity level, training goals and individual energy requirements.
