1. Understanding Diabetes and Food Choices

Diabetes is a chronic health condition characterized by elevated blood glucose levels. This occurs either because the body does not produce enough insulin (Type 1 diabetes) or cannot effectively use the insulin it produces (Type 2 diabetes). Prediabetes is a condition where blood glucose levels are higher than normal but not yet high enough to be diagnosed as Type 2 diabetes. Managing diabetes through diet involves understanding how different foods affect blood glucose levels.

Type 1 Diabetes: The body does not produce insulin. People with Type 1 diabetes require insulin injections or an insulin pump to manage their blood glucose levels.
Type 2 Diabetes: The body does not make enough insulin or cannot use insulin effectively. Lifestyle changes, including diet and exercise, can help manage Type 2 diabetes. Some people with Type 2 diabetes may also need medication or insulin.
Prediabetes: Blood glucose levels are higher than normal, increasing the risk of developing Type 2 diabetes. Lifestyle changes, such as adopting a healthy diet and increasing physical activity, can often prevent or delay the onset of Type 2 diabetes.

The impact of diet on blood glucose levels is significant. Carbohydrates are the primary nutrient that affects blood glucose levels, but fats and proteins also play a role. Therefore, understanding which foods to choose and how to balance them is crucial for managing diabetes effectively.
