**Title**- The Effect of Regular Soda versus Caffeine Free Soda on Blood Sugar Levels

**Abstract**- In this experiment we tested two males and two females to find out their normal blood sugar level. Then half of the test subjects drank Diet Caffeine free Coke and the other half drank regular Coke. After the test subjects drank their Coke they waited 45 minutes and then tested their blood sugar levels. Our results showed very little change in blood sugar from control to experimental. They all had about a 5% change or less.

**Introduction**- In 16 fl oz of Regular Coca-Cola there is 54g of sugar. In a equal amount of Diet Caffeine Free Coca-Cola there is no sugar. The average blood sugar levels are 80-120. We expected the Regular Coca-Cola drinkers' blood sugar levels to go up, and the Diet Caffeine Free drinkers to stay the same. The reason for this study is to see if Diet Caffeine Free soda affects your blood sugar differently then regular soda.

**Method**- We are testing the effect of caffeine free soda versus regular soda on blood sugar. We are using two females and two males. One guy and one girl will do the regular soda and another guy and girl will do the caffeine free soda. Our experimental group consists of the people's blood sugar levels who drink the soda. Our control group is our blood sugar levels before we drink anything. The procedure to do this experiment is that first we will prick our fingers with a SurgiLance Safety Lancet. Then we will test our blood sugar level with the FreeStyle Lite Blood Glucose Testing System. After that we will drink our designated sodas. 45 minutes later we will test our blood sugar again using the lancet and testing system to see how much the blood sugar level changed, if it changed at all. **Results**- Male 1's blood sugar before the experiment was 105 and after the experiment was 103 with a percent change of -1.9%. Male 2's blood sugar before the experiment was 122 and after the experiment was 117 with a percent change of -4.46%. Female 1's blood sugar before the experiment was 116 and after the experiment was 111 with a percent change of -4.31%. Female 2's blood sugar before the experiment was 98 and after the experiment was 103 with 5.1% change. None of our results were significantly different from their control result. All the results were about 5% different and below.

<span style="font-family: Arial,Helvetica,sans-serif;">**Discussion**- Our results were that male 1's change in blood sugar level was a -1.9% change. Male's 2 change was -4.46%. Female 1's blood sugar change was -4.31% and finally female 2's results showed a +5.1% change.Our results were not what we expected. We were expecting there to be a bigger change then what results what the showed. Overall, our results didn't really show what we expected.
