Differences between Sugar and Starch

One of the most talked about topics in the health and fitness industry is sugar vs. starch. Some people say that sugar is bad for you, while others say that starch is just as bad. So, what’s the difference between these two? And which one should you be avoiding? Here’s a breakdown of everything you need to know about sugar and starch.

What is Sugar?

  • Sugar is a type of carbohydrate that is found in many everyday food items, such as fruits, vegetables, and grains. It is also added to processed foods, such as candy, cookies, and soda. Sugar occurs naturally in most living things and is essential for the body to function properly.
  • However, too much sugar can lead to health problems, such as tooth decay and obesity. Sugar is made up of two molecules: glucose and fructose. Glucose is the main source of energy for the body, while fructose is mainly used by the liver. Sugar can be eaten in its natural form or added to food.
  • It can also be turned into alcohol or used as a medicine. Sugar has been around for thousands of years and was once only available to the wealthy. Today, it is one of the most popular sweeteners in the world.

What is Starch?

  • Starch is a type of carbohydrate that is found in many plants. It is made up of long chains of glucose molecules, which are connected together by chemical bonds. Starch is an important food source for both animals and humans.
  • When we eat starchy foods such as bread, rice, or potatoes, our digestive system breaks down the starch into glucose, which is then absorbed into the blood. Glucose is a vital energy source for our cells, and it helps to keep our blood sugar levels stable.
  • Starch can also be used as food for bacteria in the large intestine. Some types of starch are resistant to digestion and can act as dietary fiber, which is important for promoting bowel regularity. Starch is a complex carbohydrate that plays an important role in human nutrition.

Differences between Sugar and Starch

Sugar and starch are both carbohydrates, but they have some significant differences. Sugar is a simple carbohydrate, while starch is a complex carbohydrate. Sugar is made up of just one type of molecule, while starch is made up of two types of molecules. Sugar is sweeter than starch, and it dissolves more easily in water. Sugar is also more rapidly absorbed by the body. Starch takes longer to digest, and it provides a slow and steady release of energy. For these reasons, sugar is often used in candies and other sweets, while starch is used in bread and other baked goods. Both sugar and starch are essential parts of a healthy diet, but they serve different purposes.


From a chemical standpoint, not much. Both are simple carbohydrates made of carbon, hydrogen and oxygen atoms. But from a physiological perspective, the two substances have very different effects on our bodies. Sugar is absorbed quickly into the bloodstream, while starch is slowly digested over time. This means that sugar causes an immediate spike in blood glucose levels, while starch has a more gradual effect. The result? Starch is less likely to cause spikes in blood sugar and insulin levels, making it a healthier choice for people with diabetes or prediabetes. So if you’re looking for a healthy way to sweeten your food without all the negative health consequences of sugar, reach for some starchy vegetables or whole grains instead!
