Peanuts are safe and beneficial for blood sugar control during pregnancy, including for women with gestational diabetes, because they have a low glycemic index (GI 13), are high in healthy fats, protein, fiber, and magnesium, and cause only a minimal impact on blood sugar levels when consumed in moderation.
Impact on Blood Sugar Levels During Pregnancy
- Low glycemic index: Peanuts have a GI of 13, meaning they cause only a small, gradual rise in blood sugar—ideal for diabetes-friendly eating patterns.
- Rich in protein, fat, and fiber: These nutrients slow carbohydrate digestion and absorption, leading to more stable post-meal blood glucose and reduced risk of gestational diabetes spikes.
- Magnesium content: High magnesium helps improve insulin sensitivity and aids overall blood sugar regulation in pregnant women.
- Satiety and weight management: Peanuts make satisfying snacks that reduce hunger cravings and prevent overeating, supporting healthier blood sugar management during pregnancy.
Practical Considerations
- Opt for plain, unsalted peanuts or natural peanut butter, as added sugars and salts in processed varieties may counter their blood sugar benefits.
- Peanuts and peanut butter are commonly recommended as safe snacks for gestational diabetes diets, but always check for personal allergies.
- Portion control is important due to peanuts’ calorie density; a handful or about 28g per snack is typical.
