Has an Alternative Sweet Changed our Past, Present, and Future?
A. Attention-getter- Halloween is a holiday that people consume a lot of candy, and the holidays are right around the corner with more delicious treats. Therefore, it may or may not be a surprised that the average American consumes 150 pounds of sugar a year.
B. Thesis- Today, I am going to talk about high fructose corn syrup, why it is used, and research of how it is affecting us.
C. Significance- Many companies have switched to high fructose corn over pure cane sugar to lower cost. As a result, it may be cheaper for us at the checkout stand, but is it affecting our health and weight.
D. Overview- I am going to discuss what high fructose corn syrup is, the increase in obese Americans, and a few tips to reduce intake of this substance.

The end result is a mixture of 55% fructose and 45% glucose, which is called "high fructose corn syrup (Mericle).
4. I have a chart to show the rise in obesity in Northern America, fast food chains that are using HFCS in the food they prepare, and how much Coke is saving since they switched...
