Editor’s Word: This text is a reprint. It was initially revealed April 8, 2017.

To most, it could appear as if storing sure veggies in a cool place, such because the storage, again porch and even the fridge, can be a good suggestion. It’d hold them cooler and assist them last more, proper?

Seems, that is not the way it works with potatoes. When potatoes get chilled, the starch in them turns to sugar they usually turn out to be powerful. They may look OK, however after they’re cooked, they could emit dangerous properties that they would not have, in any other case. They’ll turn out to be not simply barely shrunken and wrinkly, however doubtlessly poisonous.

Here is what occurs: When potatoes are chilled, an enzyme often known as invertase breaks down the sucrose (aka sugar) they include and turns it into fructose and glucose, additionally referred to as dextrose, the primary sugar manufactured by your physique and your chief supply of vitality.1

These two sugars, fructose and glucose, mix with the amino acid asparagine in potatoes and type acrylamide after they’re baked, fried or in any other case heated, in accordance a examine revealed in Danger Evaluation.2

This does not occur with frozen potatoes, nonetheless, as a result of sucrose does not get damaged down by very low temperatures. An article from New Scientist explains:3

“Acrylamide is made by one thing referred to as the Maillard response, which browns cooked meals and provides them their pleasing taste. As sugars and amino acids react collectively, they produce 1000’s of various chemical compounds.

Notably excessive ranges of acrylamide are present in starchy meals, like potatoes and bread, when cooked at temperatures over 120 [degrees] C. The chemical can be current in breakfast cereals, biscuits and low.”

As a matter of reality, acrylamide types when potatoes or different starchy meals are browned to the purpose of charring, or above 250 levels F (120 levels C).4 This may be true with baked, grilled, sautéed or roasted starchy veggies, in addition to with grains and even espresso.

Acrylamide will be present in as a lot as 40% of the energy consumed by the common American, the U.S. Meals and Drug Administration (FDA) says.9 It is also a given that almost all processed meals, as a result of they have been subjected to excessive temperatures, include acrylamide. Potato chips are an ideal instance.

Consuming largely uncooked greens brings you the best well being advantages, however whenever you do topic them and different meals to warmth, achieve this on the lowest potential temperatures, cooking them simply till accomplished, and avoiding frying, baking or broiling every time potential. On the whole, prepare dinner at a decrease temperature every time potential.

George Alexeeff, Ph.D., former deputy director on the Workplace of Environmental Well being Hazard Evaluation for California, mentioned his workplace undoubtedly believes acrylamide is a chemical folks must be involved about, and that if one thing causes most cancers in animals, it could most definitely trigger most cancers in people, too. Based on an interview at Los Angeles Occasions:11

“The Environmental Safety Company considers acrylamide doubtlessly so harmful that it has mounted the secure stage for human consumption at virtually zero, with a most permissible stage in consuming water of 0.5 elements per billion.”

Further research additionally point out that acrylamide in meals may cause most cancers. One famous that receptor-positive breast most cancers threat is elevated when this poisonous compound has been ingested.12
