Topic: You are what you eat
Aim:
To investigate the relationship between the Glycaemic Index of carbohydrate foods and their impact on energy levels and how one feels.
Hypothesis:
I think that The Glycaemic Index of carbohydrate foods will have major impact on our energy levels and how we feel. Carbohydrates consist of sugar, starch and fibre. I think sugar will have an impact on our blood sugar levels / blood glucose levels which will affect our energy levels and consequently it will affect the way we feel. I also know that foods that are not refined have more fibre and will therefore have a longer satire rate and will release energy at a constant rate. Foods that are more refined will be digested quickly and someone will get a sugar rush

The body naturally controls your blood glucose levels (with the help of insulin) to ensure there is a metabolic homeostasis (equilibrium).
The ideal blood glucose levels for normal, healthy adults are between 65mg/dl and 105 mg/dl. Your blood glucose levels will vary throughout the day, for example, in the morning, on an empty stomach, it will be between 68mg/dl and 108 mg/dl. Two hours after eating or drinking things that are high in carbohydrates, your blood glucose levels will usually be between 120mg/dl and 140 mg/dl.
Your blood glucose levels change constantly throughout the day and vary from person to person. They depend on what you eat, and how active you are.
