Glucose is a form of sugar and an important source of fuel for the body. Almost everything you eat is broken down into smaller nutrients during digestion.

Carbohydrates from foods such as bread, fruit, rice, potatoes, pasta, breakfast cereals, legumes, and sweet products are largely converted into glucose. This glucose enters the bloodstream through the intestines. From there, it is transported to the cells, where it can be used as a source of energy. Your brain, muscles, and organs in particular rely on glucose to function properly.

Your body constantly works to keep the amount of glucose in the blood within a healthy range. This balance is known as blood sugar regulation. Stable blood sugar is important for your energy levels, concentration, mood, hormone balance, and metabolism.

When you eat and your blood sugar levels rise, your body produces insulin. Insulin is made in the pancreas and allows glucose to be absorbed from the bloodstream into the cells, where it can be stored and used as energy.

What does insulin do?

• It helps regulate blood sugar levels

• It allows cells to absorb glucose

• It plays a role in energy production

• It influences fat storage and fat burning

• It affects hormones, appetite, and metabolism

Glucose and insulin are constantly working together. When this system functions well, your blood sugar remains relatively stable and your body can use energy efficiently. When this system becomes imbalanced, symptoms and health complaints may arise.
