Glycaemic Index

Why in News: Research from an international study indicates that adhering to diets with low glycaemic index and low glycaemic load may help in preventing the onset of type 2 diabetes.What is the glycaemic index (GI)? | U Perform | Blog Post

About Glycaemic Index

Blood Sugar Response:

  • Carbohydrate-containing foods are ranked based on their post-meal blood glucose response.
  • Higher blood sugar readings correspond to higher Glycaemic Index (GI) values.

Impact on Blood Sugar:

  • GI indicates how rapidly a food affects blood sugar levels when consumed individually.
  • Foods are rated on a scale of 0 to 100, with pure glucose having a GI of 100.

Influence of Processing and Composition:

  • Lower GI foods lead to a slower increase in blood sugar levels post-consumption.
  • Generally, processed foods have higher GI values, while foods rich in fiber or fat tend to have lower GI values.

Explaining Glycaemic Load:

Glycaemic load (GL) considers both the quality and quantity of carbohydrates in a particular food.

It is calculated by multiplying the GI of a food by the amount of available carbohydrates in a serving.

Insight into Diabetes:

Chronic Condition:

  • Diabetes is a chronic ailment resulting from the inability of the pancreas to produce sufficient insulin or the body’s ineffectiveness in utilizing the produced insulin.

Role of Insulin:

  • Insulin, a hormone, regulates blood glucose levels in the body.
  • Inadequate insulin production or utilization leads to elevated blood glucose levels, termed hyperglycaemia.

Long-term Effects:

  • Prolonged high glucose levels are linked to bodily damage and dysfunction of various organs and tissues.

Types of Diabetes:

Type 1 Diabetes:

  • An autoimmune condition where the immune system targets and destroys insulin-producing beta cells in the pancreas.
  • Individuals with type 1 diabetes typically produce little to no insulin and require daily insulin administration.
  • Formerly known as juvenile diabetes, it often manifests in children and young adults.

Type 2 Diabetes:

  • Arises from the body’s ineffective utilization of the insulin it produces.
  • Primarily associated with excess body weight and physical inactivity.
