In many areas, including North America and the United Kingdom, pumpkin traditionally refers to only certain round, orange varieties of winter squash, predominantly derived from Cucurbita pepo, while in Australian English, pumpkin can refer to winter squash of any appearance.
Energy drinks contain very high levels of caffeine. A single 5-hour Energy shot contains almost as much caffeine as four 12-oz. cans of Mountain Dew. While many people will tell you that Mountain Dew has the most caffeine of any soft drink, that is incorrect. A 12-ounce (355 ml) can of Mountain Dew has about 55 mg of caffeine, compared to 72 mg in the same amount of Jolt Cola, 69 mg for Pepsi MAX, 63 to 69 mg for Sun Drop, or 59 mg for Sugar-free Mr. Pibb.
There is no caffeine limitation in food made by Food and Drug Administration. A 0.02 % caffeine content is generally recognized as safe for cola-type beverages, said FDA spokeswoman Veronica Castro. This means 72 mg of caffeine in a 12-ounce (0.4 l) soft drink. The new study revealed the fact that the caffeine levels in 12-ounce sodas varied from 4.9 mg in a cola brand to 74 mg in Vault Zero, a citrus drink.
