Both grapes and apples have a low glycemic index (GI) and are considered good fruit choices for blood sugar control during pregnancy, but apples have a slightly lower GI, making them marginally better for minimizing blood sugar spikes.
Glycemic Index Comparison
| Fruit | Glycemic Index (GI) | Effect on Blood Sugar |
| Grapes | 45 | Low/moderate, gradual rise |
| Apples | 32–38 | Low, gradual steady rise |
- Both fruits: Contain fiber, which slows the absorption of sugar and helps stabilize blood glucose.
- Grapes: Associated in one study with a reduced risk of gestational diabetes when consumed in moderation during early pregnancy.
- Apples: Also linked with reduced diabetes risk and may provide an extra edge due to slightly lower GI and higher fiber content (especially if eaten with the skin).
Recommendations
- For most people during pregnancy, both apples and grapes can be eaten in moderation without significantly raising blood sugar.
- Those with gestational diabetes or high blood sugar risk may prefer apples as the best daily option, but both can fit into a balanced diet.
- Always prioritize whole fruits over juices for better blood sugar control.
In summary, apples have a slightly better profile for blood sugar stability, but both can be included in a healthy pregnancy diet focused on moderation and variety.
