Understanding Glycemic Index (GI)

What is Glycemic Index?

The Glycemic Index (GI) ranks carbohydrates according to their effect on blood glucose levels. This numerical system measures how quickly a food raises blood sugar.

Low GI (≤55)

Slow digestion, gradual blood sugar rise

  • Legumes
  • Most fruits
  • Steel-cut oats

Medium GI (56-69)

Moderate digestion and blood sugar impact

  • Brown rice
  • Sweet corn
  • Whole wheat bread

High GI (≥70)

Rapid digestion, quick blood sugar spike

  • White bread
  • Rice cakes
  • Processed snacks

Factors Affecting GI

Food Processing

More processed foods typically have higher GI values

Ripeness

Riper fruits have higher GI values

Cooking Method

Longer cooking times can increase GI

Fiber Content

Higher fiber typically means lower GI

Glycemic Load (GL): The Complete Picture

Understanding Glycemic Load

Glycemic Load provides a more accurate picture of a food’s impact on blood sugar by considering both the quality (GI) and quantity of carbohydrates.

GL Calculation

GL = (GI × Net Carbs) ÷ 100

Example: Apple (100g)

  • GI: 38
  • Net Carbs: 13g
  • GL = (38 × 13) ÷ 100 = 4.9

GL Ranges Guide

Low GL (≤10)

Minimal blood sugar impact

Ideal for daily consumption

Medium GL (11-19)

Moderate blood sugar impact

Consume in moderation

High GL (≥20)

Significant blood sugar impact

Limit consumption

Lifestyle Integration

Daily Implementation

🥗 Food Combinations

  • Pair high GI foods with protein
  • Add healthy fats to meals
  • Include fiber-rich vegetables
  • Balance meal components

⏰ Timing Considerations

  • Space meals 3-4 hours apart
  • Consider pre-workout timing
  • Plan evening meals carefully
  • Maintain consistent meal times

Special Considerations

🏃‍♂️ Athletes

Strategic use of high GI foods for energy and recovery

  • Pre-workout: Low to medium GI
  • During: High GI for extended sessions
  • Post-workout: High GI + protein

🤰 Pregnancy

Balanced approach for gestational health

  • Focus on stable blood sugar
  • Regular small meals
  • Monitor GI impact
