Study Notes
Glycemic Index (GI)
- Measures how quickly the carbohydrates in a food raise blood sugar levels after consumption
- Ranked on a scale from 0 to 100, with pure glucose as the reference point (GI=100)
Foods with Rapid Blood Sugar Spikes
- Refined carbohydrates, such as white bread, sugary drinks, and baked goods
- High-carbohydrate foods with low fiber and water content, like potatoes and cornflakes
Impact of High GI/GL Foods on Health
- Consuming high GI/GL foods regularly can lead to insulin resistance, type 2 diabetes, and cardiovascular disease
- Associated with an increased risk of obesity, metabolic syndrome, and certain cancers
Healthier Carbohydrate Choices
- Whole, unprocessed foods like whole grains, fruits, and vegetables
- Foods with higher fiber and water content, which slow down carbohydrate digestion and absorption
Importance of Individual Dietary Needs
- Different people respond differently to various carbohydrate sources due to factors like body composition, physical activity, and genetic makeup
- Considering individual dietary needs helps to optimize carbohydrate intake and minimize potential health risks
