One example of complex carbohydrates is dietary fibre, it is found that consuming high GI food such as dietary fibre promote good benefits to its host. Another subsidiary of complex carbohydrates are resistant starch (green unripe banana, cooked and cooled food, etc.), which in indigestible type of carbohydrates, but instead become food for the gut microbiome.

The results didn’t show what was expected as since it was a foodstuff that only contained carbohydrate. It also had a high GI and therefore was expected to raise blood glucose levels more quickly than those that also contain fats and protein. Also liquids that contain carbohydrates will cause blood glucose levels to rise faster than solids that contain carbohydrates, as they don’t need to be broken down and allow for rapid absorption. Results may not have resembled this, as group 1 did not fast which makes the data a misrepresentation.…
