What are Carbs?
Carbs, short for carbohydrates, are one of the three macronutrients, along with protein and fat, that are essential for a healthy diet. They are one of the body’s primary sources of energy and can be found in many different types of food, including fruits, vegetables, grains, and sugars.
Carbohydrates are made up of carbon, hydrogen, and oxygen molecules, and they come in two main forms: simple and complex. Simple carbohydrates are made up of one or two sugar molecules and are quickly broken down and absorbed by the body, providing a quick source of energy. Complex carbohydrates, on the other hand, are made up of long chains of sugar molecules and take longer to break down and absorb, providing a more sustained source of energy.
While carbohydrates are an important part of a healthy diet, it’s important to choose them wisely and not to consume too much of them.
High intake of simple carbohydrates, particularly refined sugars, can lead to spikes in blood sugar levels and an increased risk of obesity, type 2 diabetes, and other health problems. On the other hand, complex carbohydrates, particularly those found in whole grains, fruits, and vegetables, can provide important nutrients and fibre to help support overall health.
Why Does the Body Need Carbohydrates?
The body needs carbohydrates for several reasons:
Energy: Carbohydrates are the body’s primary source of energy. When consumed, they are broken down into glucose, which is used by cells throughout the body as fuel. The brain and nervous system in particular rely heavily on glucose for energy.
Protein sparing: When the body doesn’t have enough carbohydrates for energy, it may start breaking down protein in the muscles for fuel. By providing a source of energy, carbohydrates can help spare protein and prevent muscle breakdown.
Preventing ketosis: When the body doesn’t have enough carbohydrates for energy, it may start breaking down fat for fuel. This can lead to the production of ketones, which can be harmful in large amounts. Consuming enough carbohydrates can prevent ketosis and promote overall health.
Supporting digestion: Carbohydrates are an important source of fibre, which can help support digestive health by promoting regular bowel movements and preventing constipation.
It’s important to note that not all carbohydrates are created equal. Simple carbohydrates, particularly refined sugars, can cause spikes in blood sugar levels and may be linked to an increased risk of obesity, type 2 diabetes, and other health problems.
On the other hand, complex carbohydrates, particularly those found in whole grains, fruits, and vegetables, can provide important nutrients and fibre to help support overall health.

What are Macronutrients?
Macronutrients are the three main categories of nutrients that are essential for human health and are required in relatively large amounts in the diet. The three macronutrients are carbohydrates, proteins, and fats. Each of these nutrients serves a unique role in the body and is required in different amounts.
- Carbohydrates are the body’s primary source of energy and are found in foods like grains, fruits, and vegetables. They are broken down into glucose, which is used by cells throughout the body as fuel.
- Proteins are important for building and repairing tissues, as well as for producing enzymes and hormones. They are found in foods like meat, fish, eggs, beans, and nuts.
- Fats are important for providing energy, insulation, and protection for organs. They are found in foods like nuts, seeds, oils, and animal products.
In addition to these three macronutrients, there are also micronutrients, which are essential in smaller amounts, and include vitamins and minerals. A healthy diet should include a balance of all of these essential nutrients in appropriate amounts to support overall health and well-being.
What is the Glycemic Index?
The glycemic index (GI) is a measure of how quickly and how much a particular food can raise blood sugar levels after it is consumed. The GI is a scale from 0 to 100, with pure glucose being assigned a value of 100. Foods that are high on the glycemic index cause a rapid increase in blood sugar levels, while foods that are low on the glycemic index cause a slower, more gradual increase.
The glycemic index is based on how much a food affects blood sugar levels over a period of two hours after it is consumed. Foods that are high on the glycemic index are typically those that contain simple carbohydrates, such as refined sugars and white bread, while foods that are low on the glycemic index are typically those that contain complex carbohydrates, such as whole grains, fruits, and vegetables.
The glycemic index can be a useful tool for people with diabetes, as it can help them manage their blood sugar levels. Eating foods that are low on the glycemic index can help prevent spikes in blood sugar levels, which can be harmful for people with diabetes. However, it’s important to note that the glycemic index should not be the only factor considered when choosing foods, as other factors such as overall nutritional value and portion size are also important.
