Introduction to Glucose – LeanSpoon Blog


Glucose is the example of simple carbohydrate. It is the basic source of energy for every cell in the body.

The body breaks down the carbohydrates into glucose, then the glucose is absorbed into the bloodstream which is used by the brain and other tissues.

Importance of glucose in our body:

1. Glucose as Fuel

Glucose can be stored as glycogen in the liver when you are starving, glycogen breaks down into glucose to maintain adequate sugar level and to provide energy to the brain to perform its functions.

2. The Brain Energy

Brain is the most complex and it requires a profuse amount of energy to perform its actions. Glucose provides the energy required by the brain cells.

3. Brain Functions

Our brain is completely dependent on the availability of glucose to perform its functions like, thinking, learning, responsiveness, a memory which are all linked with glucose flow and how effectively brain utilizes the glucose. Lack of glucose can cause impaired connection between neurons and neurotransmitter. Glucose can stimulate the brain cells and can improve memory level. It aids into several cognitive actions of the brain.

4. Blood Sugar Level

The term blood sugar defines the presence of glucose in the blood. There are conditions where blood sugars level can be high or low, it is called hyperglycemia and hypoglycemia respectively. Hypoglycaemia leads to inadequate energy for brain function resulting dizziness.

In recent studies, it has been shown that glucose injection can accelerate functioning of the brain. It has been observed that few people who are weight watchers or suffering from diabetes prefer no carb diet. This practice on a long-term basis may hamper the functioning of the brain. To be healthy you need food from all the food groups. If you want to know more about it then write back to us at so that our nutritionists can get back to you
