To understand the nature of Pringles and other stackable chips, forget the notion that they come from actual potatoes in any recognizable way.
The Pringles Company (in an effort to avoid taxes levied against “luxury foods” like chips in the UK) once even argued that the potato content of their chips was so low that they are technically not even potato chips.
So if they’re not made of potatoes, what are they exactly?
The process begins with a slurry of rice, wheat, corn, and potato flakes that are pressed into shape.
This dough-like substance is then rolled out into an ultra-thin sheet cut into chip-cookies by a machine.
According to io9:1
“The chips move forward on a conveyor belt until they’re pressed onto molds, which give them the curve that makes them fit into one another.
Those molds move through boiling oil… Then they’re blown dry, sprayed with powdered flavors, and at last, flipped onto a slower-moving conveyor belt in a way that allows them to stack.
From then on, it’s into the cans… and off towards the innocent mouths of the consumers.”
I suspect nearly everyone reading this likely enjoys the taste of potato chips. However, they are clearly one of the most toxic processed foods you can eat—whether they’re made from actual potato shavings or not.
Potato Chips Are Loaded with This Cancer-Causing Chemical
One of the most hazardous ingredients in potato chips is not intentionally added, but rather is a byproduct of the processing.
Acrylamide, a cancer-causing and potentially neurotoxic chemical, is created when carbohydrate-rich foods are cooked at high temperatures, whether baked, fried, roasted, or toasted. Some of the worst offenders include potato chips and French fries, but many foods cooked or processed at temperatures above 212°F (100°C) may contain acrylamide. As a general rule, the chemical is formed when food is heated enough to produce a fairly dry and brown/yellow surface. Hence, it can be found in:
- Potatoes: chips, French fries, and other roasted or fried potato foods
- Grains: bread crust, toast, crisp bread, roasted breakfast cereals, and various processed snacks
- Coffee: roasted coffee beans and ground coffee powder. Surprisingly, coffee substitutes based on chicory actually contains 2-3 times MORE acrylamide than real coffee
How Much Acrylamide Are You Consuming?
The federal limit for acrylamide in drinking water is 0.5 parts per billion, or about 0.12 micrograms in an eight-ounce glass of water. However, a six-ounce serving of French fries can contain 60 micrograms of acrylamide, or about FIVE HUNDRED times over the allowable limit.
Similarly, potato chips are notoriously high in this dangerous chemical. So high, in fact, that in 2005 the state of California actually sued makers of potato chips for failing to warn California consumers about the health risks of acrylamide in their products. A settlement was reached in 20082 when Frito-Lay and several other potato chip makers agreed to reduce the acrylamide levels in their chips to 275 parts per billion (ppb) by 2011, which is low enough to avoid needing a cancer warning label.
The 2005 report “How Potato Chips Stack Up: Levels of Cancer-Causing Acrylamide in Popular Brands of Potato Chips,”3 issued by the California-based Environmental Law Foundation (ELF),4 spelled out the dangers of this popular snack. Their analysis found that all potato chip products tested exceeded the legal limit of acrylamide by a minimum of 39 times, and as much as 910 times! Some of the worst offenders at that time included:
- Cape Cod Robust Russet: 910 times the legal limit of acrylamide
- Kettle Chips (lightly salted): 505 times
- Kettle Chips (honey dijon): 495 times
