There's a reason you can't just have one potato chip. We all know once you start munching away on the crispy snack , it is really hard to stop. And it doesn't even have to do with the taste of the potato chips either. That's right, the reason you find them so addicting is all because another one of your senses goes into overload. We break it down for you and why once you stop, the fun—the food—doesn't stop. Until the mid 20th century crisps came only with salt, but as cellophane packaging replaced greased paper bags to extend shelf life, more flavours came in.
These have become wackier, from langoustine and lemon to chocolate and gin and tonic. Because our taste buds can detect five tastes — bitter, sour, sweet, salt and meatiness — manufacturers often use flavours that use as many of these as possible. Pringles Texas Barbecue flavour contains citric and malic acid and monosodium glutamate MSG as well as salt and sugar, stimulating four out of five of the tastes for maximum impact.
In a competitive market nothing is left to chance, not even the shape of the crisp — Pringles, a blend of potato and wheat are curved so they reach as many taste buds as possible. Gourmet crisps have been developed to convince health-conscious adults that some fried potatoes are less bad for us.
And celebrity endorsements prove persuasive among children. A Liverpool University study found that those aged between eight and 11 were much more likely to choose Walkers crisps over unbranded snacks, after watching Gary Lineker advertising them on TV.
Crisps are the largest single contributor to the U. The GI, or glycaemic index database maintained at the University of Sydney has better news, however.
It suggests that potato crisp samples have shown a medium to low GI range, meaning that eating crisps may not result in higher blood sugar levels. In the British Heart foundation warned that eating a packet of crisps a day was the equivalent of drinking five litres of cooking oil a year.
Manufacturers cut saturated fat levels in response, but the frying process still gives cause for concern. Tests have shown that when starchy foods, like crisps, are fried at a high temperature toxic chemical acrylamide is produced. A Bradford Institute for Health Research study linked acrylamide intake in crisp-eating pregnant women to lower birth weight and head circumference in newborns.
It has not been established whether the link between these is causal, however. Both of these factors can lead to delayed development of the brain and nervous system, type 2 diabetes and heart disease. The average packet of crisps contains about 0. A team of Duke University Medical Center and Australian scientists took a hard look at what happens in the hypothalamus — a region of the brain that is responsible for keeping the salt and water content in balance, maintaining the blood pressure, heart rate, and so on — when mice craved salt.
They induced stress hormones this increased the need for salt in mice and withheld salt from them. When the mice craved salt, a certain region in the hypothalamus became receptive to dopamine, a chemical that induces the feeling of pleasure via Psychology Today , and is, as the Science Daily report puts it, "the brain's internal currency for reward.
So whenever the mice finally consumed the salt, what they were left with was a feeling of reward, gratification, and a craving for more. With salt in the spotlight, many tend to overlook the sugar that sits camouflaged as starch in the potato.
It is, in fact, absorbed more quickly than actual sugar of a similar amount, according to Eric Rimm, an associate professor of epidemiology and nutrition, Harvard School of Public Health. Rimm told The New York Times Magazine that the starch in the potato causes the glucose levels in the blood to rise.
And just as rapid is the rise, so is the fall of the glucose level, thereby making you want one more chip. And then some more. But isn't it strange that you never feel full eating a bag of chips? Have you ever found yourself digging into a bag of sour cream and onion chips thanks to a super-stressful day at the office? You want junk food. So instead of mindlessly stuffing your hand in a bag of chips, try taking a walk outside, going to a yoga class, or another activity that calms your nerves preferably not something that gives you the munchies.
But you should still eat your veggies at SOME point. Instead, go for some tortilla chips. Tirmandi suggests picking brands of blue corn chips that are both non-GMO and organic. Your stomach is grumbling at 3pm. Try some pistachios! Starting to sound good, right?
