Understanding Carbohydrates: Simple vs. Complex Carbs Explained

Along with proteins and fats, carbohydrates are one of the three primary macronutrients that give the body energy. In terms of chemistry, they are organic substances composed of oxygen, hydrogen, and carbon. Foods including grains, fruits, vegetables, and dairy products are the main sources of carbohydrates. The body converts them into glucose, or sugar, which is an essential source of energy for the muscles, brain, and other physiological processes.

Carbohydrates are classified into two types: simple carbohydrates (sugars) and complex carbohydrates (starches and fiber). While complex carbohydrates digest more slowly and provide longer-lasting energy, simple carbohydrates digest more swiftly and provide energy immediately. Maintaining general health and energy levels requires a balanced intake of nutritious carbs

If you have certain health conditions, you may need to count your carbs. On average, people should get 45 to 65% of their calories from carbohydrates every day. The Daily Nutritional Value for total carbohydrates is 275 g per day. This is based on a 2,000-calorie daily diet. Your Daily Value may be higher or lower depending on your calorie needs and health.

Functions of Carbohydrates

Carbohydrates have several essential functions in the body:

Primary energy source: The main energy source is carbohydrates, which offer a rapid and effective energy supply. Carbohydrates are broken down into glucose, or blood sugar, which the body uses as fuel.

Energy storage: Extra glucose can be stored for later use as glycogen in the muscles and liver.

Supporting brain function: Glucose is the main energy source for the brain. The body cannot sustain proper brain function without sufficient carbohydrate consumption, which results in problems including exhaustion and difficulty focusing.

Protein sparing: The body uses available carbs as fuel, allowing proteins to be utilized for development and repair rather than being broken down for energy.

Regulating fat metabolism: Carbohydrates play a role in fat metabolism. Inadequate carbohydrates can cause the body to rely on fat for energy, producing ketones, which can lead to ketosis. On the flip side, if excess carbohydrates and sugars are consumed the excess glucose that is available after utilization can be converted to fats and stored in the subcutaneous tissues.

The Advantages of Eating ideal amount of Carbohydrates ( Not in excess, which happens commonly)

You should include basic amount of carbohydrates in your diet for the following reasons:

They supply energy. Glucose is the primary fuel produced by the breakdown of carbohydrates. Carbohydrates are a more effective energy source than fat or protein.

Whole foods that contain carbs are rich in nutrients. Numerous vitamins and minerals can be found in fruits, vegetables, and whole grains. They also include phytonutrients, which are plant components that have anti-disease properties.

Fiber comes from complex carbohydrates. Fiber can balance blood sugar and decrease cholesterol in addition to helping with digestion. You can reduce your risk of heart disease and several cancers by eating more foods high in fibre.

You can maintain a healthy weight by eating complex carbohydrates. Many nutritious types of carbohydrates make you feel full because they are substantial.

You can maintain a healthy weight by eating complex carbohydrates. Due to their size, a lot of nutritious carbs make you feel full, which encourages you to eat less. There isn't much proof that eating healthy carbohydrates causes weight gain.

Do keep in mind that consumption of excess amounts of carbohydrates & sugars is not advisable.

Carbohydrates and Glycemic Index (GI)

Not all carbohydrates affect the body in the same way. The glycemic index (GI) measures how quickly a food raises blood sugar levels after consumption. Foods with a high GI, such as sugary snacks or white bread, are rapidly digested and cause quick spikes in blood sugar. Foods with a low GI, such as whole grains, legumes, and vegetables, release glucose more gradually and help maintain steady energy levels.

• High GI foods: Glucose, white bread, white rice, sugary drinks.
• Low GI foods: Whole oats, brown rice, sweet potatoes, legumes.

Simple and complex carbohydrates

1. Simple Carbohydrates

Simple carbohydrates are made up of one or two sugar units, making them quick sources of energy for the body.

Monosaccharides (Single Sugar Units):

• These are the simplest form of carbohydrates.
• Common examples include:
  • Glucose: The body's primary source of energy.
  • Fructose: Found in fruits and honey.
  • Galactose: Found in dairy products as part of lactose.

Disaccharides (Two Sugar Units):

• Made by combining two monosaccharides.
• Examples include:
  • Sucrose (table sugar): Made from glucose and fructose.
  • Lactose (milk sugar): Made from glucose and galactose.
  • Maltose: Made from two glucose units, often found in germinating grains.

Characteristics of Simple Carbohydrates:

• They are quickly digested and absorbed by the body, leading to a rapid increase in blood sugar levels (blood glucose). This can provide quick energy but may also lead to blood sugar spikes followed by crashes, especially when consumed in large amounts or when they are refined sugars (like those in sweets and processed foods)
• Found in foods like fruits, milk, sweets, soda, and processed snacks.

Sources of Simple Carbohydrates:

• Natural sources: Simple carbs can be found naturally in fruits, vegetables, milk, and honey. These provide not just sugar but also essential nutrients, vitamins, and minerals.
• Processed sources: Simple carbohydrates are also found in processed foods, such as sugary snacks, soda, candy, and baked goods. These types of simple carbs often lack essential nutrients and fiber and are referred to as "refined sugars.

Health Implications:

• Simple carbs can lead to spikes and crashes in blood sugar, which can leave you feeling tired or hungry soon after eating.
• Overconsumption of simple sugars, especially refined sugars (like in candies and sodas), is associated with weight gain, insulin resistance, and increased risk of chronic conditions like type 2 diabetes.

2. Complex Carbohydrates

Complex carbohydrates are made up of three or more sugar units (polysaccharides). They are more complex in structure and take longer for the body to break down.

Polysaccharides (Many Sugar Units):

• Examples include:
  • Starches: Found in foods like potatoes, corn, rice, pasta, and bread. Starch is the storage form of glucose in plants.
  • Fiber: Found in plant-based foods, such as fruits, vegetables, whole grains, legumes, and nuts. Fiber is not digested by the body but plays an essential role in digestion and maintaining gut health. There are two main types of fibre:

Soluble Fiber: Found in oats, apples, and beans, it dissolves in water and can help lower cholesterol and blood sugar levels.

Insoluble Fiber: Found in whole grains, nuts, and vegetables, it helps move food through the digestive system, promoting regular bowel movements and preventing constipation.

Characteristics of Complex Carbohydrates:

• They are digested more slowly compared to simple carbs, leading to a gradual increase in blood sugar. This provides sustained energy over a longer period.
• The body first breaks down starch into simpler sugars like glucose, which can be absorbed into the bloodstream. Since this process is slower, complex carbs cause a gradual rise in blood sugar levels, which helps maintain energy levels throughout the day.
• The fibre in complex carbs, especially insoluble fiber, moves through the digestive system without being broken down. It helps regulate digestion, prevents constipation, and may reduce the risk of developing certain digestive disorders.
• Foods high in complex carbs tend to be rich in fiber, vitamins, and minerals, contributing to overall health.

Health Implications:

• Complex carbs, especially those high in fibre, help with digestion, promote satiety (fullness), and may reduce the risk of heart disease, diabetes, and certain cancers.
• Sources of complex carbs like whole grains, legumes, and vegetables also provide essential nutrients such as antioxidants and vitamins that are vital for health.

Comparison of Simple and Complex Carbohydrates:

Modern day diets have more amount of simple carbs in the processed and packaged foods and inadvertently we tend to consume more carbs than needed. This leads to a blood sugar roller coaster of rapid rise and fall and also the excess glucose in the body gets converted to fat and bad cholesterol and accumulates in the body leading to health problems like strokes and heart attacks. An easy and effective way to keep carbs in check without too much compromise is the use of Carb cutters like Moder/ate calorie Crusher. It is a natural plant based product that cuts out some of the carbs and sugars entering into our body. It is scientifically proven and safe to use on a regular daily basis.
