The Low Glycemic Index Diet for Gestational Diabetes

If you have gestational diabetes, it’s important to keep your blood sugar levels in a healthy range. Certain foods raise your blood sugar faster than others, so you’ll need to watch what you eat.

When making meals and snacks that will keep blood sugar steady, it can be helpful to think about three main parts of the plate. The three main groups of food are carbohydrates, non-starchy vegetables, and proteins.

Rules for Eating with Gestational Diabetes

  • Carbohydrates raise blood sugar the most.
  • Pair carbohydrates with veggies or protein to slow down the rise.
  • Test and learn which carbohydrate foods work best for you.

Carbohydrates

Carbohydrates, which are in foods like grains and sweets, have the biggest effect on blood sugar. Your body turns carbohydrates into glucose, which gives you and your baby energy.

But too many carbs at once can make your blood sugar go too high. Balance carbs with other foods to keep blood sugar steady.

What Foods Have Carbohydrates?

  • Milk and yogurt
  • Fruits and juices
  • Rice, grains, cereals, and pasta
  • Breads, tortillas, crackers, bagels, and rolls
  • Beans, split peas, and lentils
  • All potatoes, corn, yams, cassava, yucca, peas, and winter squash

What Is a Healthy Serving of Carbohydrates?

  • One serving of carbohydrates is about 15 grams. This should take up about one quarter of a 9-inch plate.
  • Ask your dietitian how much is right for you, but in general, you should have:
    • Meals: 30–60 grams of carbohydrates
    • Snacks: 0–30 grams of carbohydrates

These amounts keep you full and help your baby grow in a healthy way.

Non-Starchy Vegetables

Vegetables are high in fiber and low in sugar. They help steady blood sugar, not raise it. Veggies have many nutrients that help you and your baby grow healthy.

Aim to fill half your plate with vegetables.

  • That means one to two cups raw, or one half to one cup cooked.
  • Try to eat at least three portions of vegetables each day.

Examples of Non-Starchy Vegetables

Some vegetables that are particularly good for keeping your blood sugar steady include:

  • Artichoke
  • Arugula
  • Asparagus
  • Bean sprouts
  • Beets
  • Bok choy
  • Broccoli
  • Brussels sprouts
  • Cabbage
  • Carrots
  • Cauliflower
  • Celery
  • Chayote
  • Cucumber
  • Eggplant
  • Collard greens
  • Green beans
  • Jicama
  • Kale
  • Kohlrabi
  • Leeks
  • Lettuce
  • Mushrooms
  • Okra
  • Onions
  • Pea pods
  • Peppers
  • Radishes
  • Romaine
  • Rutabaga
  • Sauerkraut
  • Scallions
  • Spinach
  • Swiss chard
  • Spaghetti squash
  • Summer squash
  • Tomatoes
  • Turnips
  • Zucchini

Proteins

Foods with a lot of protein help keep your blood sugar steady and make you feel full. They are a good source of iron and give you energy.

Examples of High Protein Foods

Your serving size for protein foods should be about the size of your palm, or one quarter of a 9-inch plate.

  • Beef or buffalo
  • Chicken and turkey
  • Eggs or egg whites
  • Fish (including canned tuna)
  • Goat, lamb, and mutton
  • Nuts and nut butters
  • Pasteurized cheese
  • Pork
  • Protein powders
  • Seafood
  • Tempeh
  • Tofu

Beans, lentils, yogurt, and milk have protein, but they also have carbohydrates. It’s important to check how much of these you eat in a meal with other carbohydrates.

How Can I Keep Track of What I Eat?

Smartphone apps can help you track blood sugar, what you eat, and give you tips. Some apps to try:

  • Fooducate
  • MySugr
  • SNAQ
  • Undermyfork

Healthy Pregnancy Snack Ideas

Snacks can be helpful for your energy and blood sugar. When snacking, pick a carbohydrate paired with a fat or protein. Also, combine your snack with a large glass of water.

Some snack ideas:

  • Six crackers with cheese or nut butter
  • A small fruit with a handful of nuts or string cheese
  • Avocado toast
  • Greek yogurt with berries
