1. Why Are Refined Carbohydrates Problematic for Prediabetes?
Refined carbohydrates are problematic for prediabetes because they are rapidly digested, leading to quick spikes in blood sugar levels. These simple carbs have a high glycemic index (GI), which measures how quickly a food raises blood sugar. The faster the body breaks down a food, the higher its GI value, and the more rapidly blood sugar increases. Refined carbohydrates include white bread, white rice, pastries, and processed snacks. These foods lack fiber and essential nutrients, contributing to hunger shortly after consumption.
Research indicates that diets rich in refined carbohydrates heighten the risk of type 2 diabetes, hypertension, and heart disease. A study published in the American Journal of Clinical Nutrition found that individuals who consume large amounts of refined grains have a significantly higher risk of developing insulin resistance compared to those who eat whole grains.
1.1. What are Healthier Alternatives to Refined Carbohydrates?
Swap refined carbohydrates for complex carbohydrates, which are rich in fiber and digested more slowly. This helps prevent rapid blood sugar spikes. Complex carbohydrates also provide sustained energy and keep you feeling full longer. Examples of complex carbohydrates include:
- Whole grains: wild rice, brown rice, oatmeal, quinoa, and barley
- Starchy vegetables: corn, green peas, and potatoes
- Beans and legumes: black beans, kidney beans, black-eyed peas, split peas, and garbanzo beans
