Dark-colored sodas are considered worse for health than light-colored sodas because they have a chemical called 4-methylimidazole that is used for coloring, which was classified as potentially carcinogenic to humans by the International Agency for Research on Cancer. The chemical is abbreviated as 4-Mel, but it is listed on food labels as "caramel coloring" or "artificial coloring".Know More
California's Proposition 65 law requires all sellers to disclose a warning on any food or beverage that exposes consumers to more than 29 micrograms of 4-Mel per day, and Pepsi One and Malta Goya sodas tested higher than 29 micrograms per sample in a 2013 test by Consumer Reports. Because they exceed the limit of the law, they are required to have a warning label.
The United States Food and Drug Administration does not consider the levels of caramel coloring in foods to pose a health risk to consumers. The FDA is conducting tests on various foods and beverages with the chemical to determine its safety. If consumers have questions regarding the safety of 4-Mel in foods and beverages, the FDA offers a frequently asked questions page. While light-colored sodas may not be considered healthy, they do not include 4-Mel coloring in the ingredient list.Learn more about Soft Drinks

Blood leaving the heart, called arterial blood, is pumped from the lungs back to the heart by the pulmonary artery, and it contains a large amount of oxygen for delivery around the body. Arterial blood, therefore, appears a brighter red than deoxygenated venous blood.Full Answer >
