To begin with, the reading posits that the HFCS cause obesity. However, the lecturer opposes this claim by explaining that not the consumption of HFCS is the culprit for obesity but the irresponsible behaviour. This means that people who overeat can easily gain weight from other sources, such as bread or sugar. According to the lecturer, moderation in diet helps to maintain weight rather the exclusion HFCS from diet.
Second, the article states that cheap in production
HCFS has costly consequences in the long run. This is related to increase healthcare costs due to consumption of HCFS. The lecturer refutes this claim by saying that production of HFCS is markedly lucrative because of several reasons. One of them is that the manufacturer keep the prices low for their customer because of using syrup. Another reason is the liquid form of the that easy and cheap to handle. Finally, import of sugar cane is considered a drain of economy by the lecturer.
Third, the reading suggests that growing corn is harmful for the environment. This is because it lead to erosion of soil and depletion of nutrients out of the soil. However, the lecturer says that HCFS has no artificial colors or chemical is it. So this cannot be bad for the environment. He adds that in comparison with growing sugar cane, growing corn does not lead to devastating consequences of soil deterioration. According to the lecturer, sugar require by far more water to grow, so this results in worse soil erosion.
