Difference Between Sugar and Starch

Carbohydrate is one of the main nutrients that should be added on our daily diet because they provide us with enough energy for the whole day.

Now, carbohydrates are sugars that come in two different types that are a simple and complex form.

The simple form of carbohydrate is also known as sugars and the latter that is complex form is known as starch.

There is a difference between the two because not all people can consume sugar and starch because of some illnesses.

Sugar vs Starch

The difference between sugar and starch is that the digestion rate or the absorption rate of sugars and starch by our human body. Well, it will depend on which kind of food you are consuming. Sugars are easy to digest unlike, fibre that is not easily digested by the human body. This is the reason why diabetic patients are recommended not to consume sugary foods.

Sugar vs Starch

The kind of intake of food decides the overall health of your body and you should be aware of everything that you consume. Too much of anything can be harmful to the body and too little of anything can also be harmful too.

What is Sugar?

Sugar is a form of carbohydrate that has a sweet taste unlike, a starch that has no sweet taste.

Sugar has got energy for the human body and they are easily digested but too much can be harmful leading to diabetes.

Diabetes is something that is not rare at all because out of 10 people 8 people have got diabetes or suffering from diabetes.

So, one should be careful about what they are eating and how much they are eating.

Sugar is a form of carbohydrate and carbohydrates are mostly found in food sources like rice, bread, milk, beans, potato, and other such kinds of stuff.

Sugar is also known as a simple sugar or can also be called as simple carbohydrates.

Sugar is considered to be in their simplest form when they are inside our body and this is the reason why they are digested by our body easily.

They need not break down further for digestion. Before heading into the small intestine sugars gets mixed with the existing chyme.

Then the digestive enzymes that are present in the small intestine of the human body transform that sugar into direct glucose. This glucose is easily absorbed by the walls of the intestines.

Now, why do you think we should take sugar at least once in a while? Well, it is because sugar produces or offers an instant energy to the cells inside our body and the energy gets utilised instantly.

When there is the excess of sugar then the excess is stored and can be used later on for further utilisation of energy. The energy storage forms are of two types namely glycogen and fats.

Muscles and liver stores glycogen whereas fats are stored in the adipose tissue.

Sugars and starches are completely different from each other yet they are the two forms of carbohydrate.


What is Starch?

The complex carbohydrate is also known as starch and when they are consumed through different categories of food they are broken down first and then they are digested by the human body.

Starch is not like sugar that can be digested easily because when you consume a rich in starchy food like bread or potatoes then the cells in the mouth of the person would release an enzyme that is also known as the digestive juice for digesting.

Unlike, sugar starch is broken down into further simple sugars. The complex carbohydrate foods are rich in fibres and fibres are not easily digested by the human body because it takes some time.

Some of the sources of starches are fruits, nuts, vegetables, whole grains, and other such kinds of stuff.

This is the reason why diabetic patients are recommended to consume fibre content foods because fibre avoids the increase in sugar level inside the body.

Since the digestion of starch takes up some time the energy released is also slow unlike, the sugar which provides instant energy to the human body.


Main Differences Between Sugar and Starch

  1. Sugar is also known as simple carbohydrate whereas starch is also known as complex carbohydrate.
  2. Sugars are easily to digest unlike, starch that takes some time to digest by the human body.
  3. Sugar has a sweet taste while starch does not have a sweet taste.
  4. Starch is rich in fibre and therefore people suffering from diabetes are recommended to consume fibre-rich foods.
  5. Sugar is directly absorbed by the human body while starch is broken down into simple sugar before digestion which is time consuming.
