Soda Causes Cancer - Jason, Samuel, Wei Feng

Claim: Soda causes cancer

Supporting Details:

Fact

Statistic

Example

Testimony

Supporting details from the video:

- Minnesota School of Public Health: A study has shown a can of soda a day can increase the risk of cancer for men by 40 percent. (Statistic)

- Soda can cause obesity which can cause prostate & pancreatic cancer (Fact)

- Soda can also have an increased risk depression (Fact)

- A Centre for Science and the Public Interest removed an animal carcinogen which is known to cause cancer quickly as soon they had to declare it on the can due to a California law (Testimony)

Supporting details from the internet:

- A University of Minnesota study showed that drinking sugary drinks may raise one's risk of getting endometrial cancer. (Testimony)

-Doctors say that drinking 2 or more diet sodas per day increases one's chance of being obese by 57% (Statistic)

- Women who drank the most sweet soft drinks had a 78 percent increased risk of the cancer, researchers found. (Statistic)

- ''People who drank two or more soft drinks a week had an 87% increased risk -- or nearly twice the risk -- of pancreatic cancer compared to individuals consuming no soft drinks," says study lead author Noel T. Mueller, MPH, a research associate at the Cancer Control Program at Georgetown University Medical Center, Washington, D.C. (Statistic)

- A chemical, 4-MI, was found in unsafe levels in Coca-cola, Pepsi-cola, Dr. Pepper Snapple Group Inc's Dr. Pepper and Whole Foods' 365 Cola. (Fact)

- 4-MI, or 4-MEI, was listed by the state of California as a carcinogen in 2011 (Fact)

- In 2007, the National Toxicity Program exposed rats and mice to high doses of 4-MEI, and found that exposure to 4-MEI was linked to lung tumours in mice. (Fact)

Counter-attacking views:

- But the amount of 4-MEI present in sodas via caramel colouring is far less than what was fed to the rodents. A spokesperson added that it was important to note a consumer would have to drink more than a thousand cans of soda a day to reach the level administered to rats that developed cancer in the studies.

- However, the FDA has not listed the chemical as a known human carcinogen. The American beverage Association also slammed CSPI's findings. It said in a statement, "This is nothing more than CSPI scare tactics, and their claims are outrageous. The science simply does not show that 4-MEI in foods or beverages is a threat to human health."

- Coca-Cola Co. told CBS News that the CSPI claims were "erroneous allegations," pointing out that besides the California board mentioned in the study, no other regulatory agency that deals with public health has stated that 4-MI can cause cancer in humans. "The caramel color in all of our ingredients has been, is and always will be safe. That is a fact," Ben Sheidler with the Coca-Cola Co. public affairs and communications office told CBS News by email. Also, The other agencies may not have researched on the chemical and therefore not stated it as cancer causing.

(The chemical accumulates over time in the body.
Their studies show that people who drink soda have a higher chance of getting cancer

The other agencies may not have researched on the chemical and therefore not stated it as cancer causing)
