What to eat before and after getting a glucose test done in pregnancy, carelessness will result in diabetes

what to eat before glucose screening test

Foods can affect the glucose test test. When you eat, your body turns carbs into glucose. If you eat the wrong kind of food right before a glucose screening, you could get a false result for gestational diabetes.
Any food that is a complex carbohydrate is great to eat before this screening test because your body breaks them down slowly and these foods do not cause a spike in sugar.

what to eat

Eat whole grains (wholegrain bread, brown rice), legumes (chickpeas, lentils, black beans), fresh fruits, non-starchy vegetables, dairy, nuts and peanut butter, fish. The test is usually done in the morning. That’s why you must have a proper breakfast before going for the test. The best breakfast is to have complex carbohydrates with protein. Whole grain toast with avocado, Greek yogurt with fruit, and omelette with tomatoes.

what else to eat

You should consume 150 grams of carbs for three days before this test. According to the National Institute of Diabetes and Digestive and Kidney Diseases, you should stop eating and drinking at least 8 hours before this screening. You can take sips of water.

what not to eat

Foods high in sugar should not be consumed one hour before the test. These types of food are easily digested and cause high blood sugar levels.
Avoid fruit juices, smoothies and sodas, sweet tea, granola, refined cereals, pancakes, doughnuts, white bread and muffins. You should eat a high carbohydrate diet three days before the test. Eating a low-carb diet before this test can cause problems with insulin levels, and you can also get false results for gestational diabetes. The benefit of eating 150 grams of carbohydrates for three days is that it helps normalize insulin sensitivity and prepare your metabolism to tolerate the glucose drink you’re given during the test.
