Refined carbohydrates are digested faster, leading to a fast rise in blood glucose levels.
Refined carbohydrates have a higher glycemic index than processed whole grains. That's because of their simple chemical structure, leading to powerful spikes in blood
sugar and insulin secretion. This immediate impact can lead to an increased risk for type 2 diabetes, overweight and heart disease.

During cellular respiration, carbon dioxide is released to the atmosphere during the formation of acetyl coenzyme A<span>. This step involves the oxidative decarboxylation of pyruvic acid, the result of which is carbon dioxide. This carbon dioxide is uptaken by plants and used in the process of photosynthesis to produce glucose.</span>
