are complex carbohydrates unhealthy because they are digested quickly and rapidly release large volumes of simple sugars into the blood?

Complex carbohydrates are actually considered to be healthier than simple carbohydrates because they are digested more slowly, leading to a slower and more steady release of glucose into the bloodstream. This can help to stabilize blood sugar levels and provide sustained energy throughout the day. Additionally, complex carbohydrates are often higher in fiber, vitamins, and minerals compared to simple carbohydrates. However, some complex carbohydrates may still be refined or processed, which can remove some of their nutritional value. It is important to choose whole, unprocessed sources of complex carbohydrates, such as whole grains, legumes, fruits, and vegetables, for optimal health benefits.
