The Consumption of Donuts and Its Impact on Health
marjaan Khatam / 0
The word "donut" is derived from the Dutch word "doughnut," which is a combination of "dough" (pastry dough for baking) and "nut." The history of donuts dates back to the seventeenth and eighteenth centuries, to Dutch immigrants in New York. They prepared fried dough balls called olykoeks (oily cakes). These fried dough balls were similar to modern donuts, although they did not yet have the current ring shape. Donuts were not fully recognized as a U.S. food until the end of the twentieth century. It is said that in 1850, an American captain named Hanson Gregory invented the ring shape of the donut by creating a hole in its center, although there are various accounts of this creativity. In the mid-nineteenth century, Captain Gregory's mother, Elizabeth Gregory (a Dutch immigrant to America), made a cake fried in a lot of oil for her son and his crew, who often went on many commercial voyages by ship. Its recipe included nutmeg, cinnamon, and lemon zest. She placed hazelnuts or walnuts in the middle of these pastries. Some historians believe that Captain Gregory made the hole in the middle of the donut to save on ingredients. Another account states that when Captain Gregory was steering the ship on a stormy day, to better control the rudder and use both hands at the same time, he inserted the donut from the middle into one of the wooden rods of the rudder, and the idea of inventing the current ring donut came to his mind.

Food poisoning from rice and pasta

Foodborne illnesses, including food poisoning, are major public health concerns. These illnesses impose significant annual costs on various countries, regardless of their development status. Bacillus cereus is a known pathogen that causes food poisoning. Due to its ability to produce resistant spores (a resistant form of bacteria), it can easily survive in various environments, including raw and processed foods, leading to illness. However, the exact prevalence of diseases caused by this bacterium remains unclear, as they are often non-fatal, mild, and go undiagnosed.
