Understanding Food Impact on Blood Sugar
The radar chart above illustrates the relative impact of different food categories on various aspects of health for people with type 2 diabetes. Foods with higher scores (farther from the center) have more negative effects on that particular health aspect. As shown, sugary drinks have the highest immediate impact on blood sugar, while fried foods present the greatest cardiovascular risk.
Additional Foods to Limit or Avoid
High-Fat Dairy Products
Full-fat dairy products can contribute to increased cholesterol levels and reduced insulin sensitivity due to their high saturated fat content.
- Whole milk and cream
- Full-fat cheese and cream cheese
- Regular ice cream and frozen dairy desserts
- Full-fat yogurts, especially flavored varieties
Trans Fats and Fried Foods
Trans fats increase bad cholesterol (LDL) while decreasing good cholesterol (HDL), raising the risk of heart disease—a significant concern for diabetics.
- Deep-fried foods of all types
- Commercial baked goods with partially hydrogenated oils
- Some margarines and shortenings
- Packaged snack foods containing trans fats
Dried Fruits and Fruit Concentrates
While whole fruits are generally beneficial for people with diabetes, dried fruits contain concentrated sugars that can spike blood glucose levels.

Alcohol
Alcohol can cause unpredictable effects on blood sugar and may interfere with diabetes medications.

Glycemic Impact of Common Foods
The glycemic index (GI) and glycemic load (GL) measure how quickly and how much foods raise blood sugar levels. Foods with higher values cause faster and larger increases in blood glucose.
| Food Category | Examples | Glycemic Index | Glycemic Load | Impact on Blood Sugar |
|---|---|---|---|---|
| White Bread Products | White bread, bagels, rolls | 70-75 | High | Rapid spike |
| Sugary Beverages | Soda, fruit juice, sports drinks | 60-68 | Very High | Immediate spike |
| Breakfast Cereals | Corn flakes, rice cereals | 70-85 | High | Rapid spike |
| Processed Snacks | Crackers, pretzels, chips | 65-80 | Medium-High | Quick elevation |
| Candies & Sweets | Chocolate bars, gummy candy | 60-75 | High | Rapid spike + prolonged elevation |
| Fast Food Meals | Burgers, fries, pizza | 55-70 | High | Prolonged elevation |
| Dried Fruits | Raisins, dates, dried apricots | 60-70 | Medium-High | Moderate-to-rapid spike |
