An example of a complex carbohydrate is quinoa. Unlike simple carbohydrates, which consist of sugars that can rapidly spike blood glucose levels, complex carbohydrates are made up of longer chains of sugar molecules, providing sustained energy. Quinoa is also rich in fiber, protein, vitamins, and minerals, making it a nutritious option compared to many simple carbohydrates. Other examples of complex carbohydrates include whole grains, legumes, and vegetables. Incorporating complex carbohydrates into the diet helps regulate blood sugar levels and provides a stable source of energy for daily activities.
