and in countries of the former Yugoslavia, fried thin potato slices are known as "chips" (locally pronounced very similarly to the English pronunciation), with a clear distinction from French fries. In Brazil, "home-style" potato chips are known as ("Portuguese potatoes") if their sides are relatively smooth and ("Prussian potatoes") if their sides show a wafer biscuit-like pattern, whilst American-like industrial uniform potato chips made from a fried potato purée-based dough are known as "batata chips" ("potato chips"), or just . Health concerns Most potato chips contain high levels of sodium, from salt. This has been linked to health issues such as high blood pressure. However, researchers at Queen Mary University of London in 2004 have noted that a small "bag of ready-salted crisps" contains less salt than a serving of many breakfast cereals, including "every brand of cornflakes on sale in the UK." Some potato chip companies have responded to the long-standing concerns by investing in research and development to modify existing recipes and create health-conscious products. PepsiCo research shows that about 80% of salt on chips is not sensed by the tongue before being swallowed. Frito-Lay spent $414 million in 2009 on product development, including development of salt crystals that would reduce the salt content of Lay's potato chips without adversely affecting flavor. Unsalted chips are available, e.g. the longstanding British brand Salt 'n' Shake, whose chips are not seasoned, but instead include a small salt sachet in the bag for seasoning to taste. Many other popular brands in the United States, such as Frito-Lay, also offer such a product. One health scare related to potato chips focused on acrylamide, which is produced when potatoes are fried or baked at high temperatures. This discovery in 2002 led to international health concerns. Subsequent research has however found that it is not likely that the acrylamides in burnt or well-cooked food cause cancer in humans; Cancer Research UK categorizes the idea that burnt food causes cancer as a "myth". In August 2008, California Attorney General Jerry Brown announced a settlement with Frito-Lay, Kettle Foods, and Lance Inc., the makers of Cape Cod Potato Chips, for violating the state's Safe Drinking Water and Toxic Enforcement Act. The state had alleged in 2005 that potato chips from these companies failed to document that they contained high levels of acrylamide, which is listed by California since the 1990s as a carcinogen. These companies paid
