Purpose Statement: To investigate the effect of diet on blood sugar levels.rnrnHypothesis: rnIf foods high in sugar affect blood sugar levels, then foods with a higher glycemic index will cause a faster increase in blood sugar because they contain more sugar. rnrnThe findings have many real life uses since eating foods with a high glycemic index can lead to a risk for diabetes. Foods with low glycemic index can help control blood sugar levels and decrease the risk of diabetes. Since high glycemic index carbohydrates raise blood sugar, when making a choice of which carbohydrates to eat, it is important to consider the glycemic index. Scientific research has shown that the body functions best when your blood sugar is stable. If your blood sugar is too low, you feel tired and hungry. If it is too high, then the pancreas needs to make more insulin, to pump blood through your body. Surprisingly, eating a chocolate bar is not as bad as eating white pasta. The chocolate does not spike blood sugar as much as the white pasta. White pasta is considered a refined food, which has the nutrients and fibre removed, and therefore enters the blood faster. After eating whole wheat tortillas and multigrain rice cakes, blood sugar increased after 60 minutes. This can be explained by the fact that the whole wheat tortilla and rice cakes contain complex carbohydrates which consist of a long chain of glucose molecules. After eating the apple and brown rice, it was surprising to find that these foods caused the blood sugar to decrease after 90 minutes. rnIn the long run, my findings suggest a healthier lifestyle that can reduce the risk of health problems like diabetes. It can also help people who are trying to maintain a healthy weight or trying to lose weight, by showing which foods have less sugar in them.
