Can expired chips make you sick?

In this article, we are going to discuss whether can expired chips make you sick. We will describe what chips are made off, and what can happen if you eat expired food. 

Can expired chips make you sick?

Expired chips won’t make you sick if you eat them a month later, but they may start to lose freshness. But putting them in the oven with oil makes them crisp again. Keeping them in an airtight container extends their life by removing them from contact with moisture. 

Chips don’t typically have an expiration date. They don’t contain enough moisture for microbes to grow and spoil the chips. The date on the package is the “best before date” – the date before which the manufacturer can guarantee an optimal taste and texture. 

Your best rule of thumb is your senses. Do they look ok, do they smell ok, do they taste ok? Chips are more likely to get stale long before they become rancid. And rancid is mainly an esthetic issue, rather than a nutritional one. Rancid just smells terrible and tastes terrible.

Easy to produce, pack and sell, potato chips have become the favorite snacks, especially among children and young people.

Potato chips contain substantial amounts of sodium. Thus, on average, 100g of chips have 500mg of sodium – this would explain why the chips do not expire so quickly.

All french fries, including chips, contain large amounts of fat. These fats result from frying them in large quantities of oil. The oils used are usually sunflower, corn, or cottonseed oil, which seems to be very cheap and preferred by manufacturers.

Here are some brands of chips and their content:

What happens if you eat food after the expiration date

“Consume before…”: everyone has heard of this expression, which must be used on all packaging. Ignoring how annoying it is that you expect the date to be written further, but all you find written is “see on the package,” and the date is stamped somewhere as hidden as possible, what does this data mean?

Sure, it’s the date the product expires, what happens if you eat food after the expiration date?

Well, the date written on the packaging is the day until the manufacturer recommends consuming those foods. In other words, after that date, the manufacturers no longer guarantee the freshness of the product or for the safety of its consumption.

What happens after the expiration date? It depends on the type of product. There may be products to eat safely, such as pasta, a bag of salt, or even bread if they are still packaged and stored correctly.

But most products should not be consumed after the date mentioned on the package, especially if they are dairy products (except for matured cheeses), meat products, or containing eggs.

What happens if you eat food after the expiration date? In most situations, nothing. 

Many foods, except perishable ones (meat, dairy, eggs, fruits), will retain their nutritional qualities and will not be contaminated if you keep them in optimal conditions. In the worst case, they will change their taste, in which case you will not want to consume them anyway.

In the case of perishable foods, however, it’s like playing Russian roulette. If nothing has happened to you so far, it doesn’t mean that the next expired yogurt may not have developed a common bacterium, such as e-coli, that can give you health problems for a few days.

A useful trick that helps you realize the freshness of a product or a dish if we are talking about a meal served at the restaurant is always to trust your senses, especially the smell. If it looks good but doesn’t smell right, don’t eat it. The development of bacteria brings with it the alteration of the aroma of the preparation and, even if it is not a strong smell, which will move your nose, it can give you a hint about freshness.

Can you eat foods that have mold if you remove the affected part?

Of course, we are not talking about brie or other cheeses with noble molds, but about foods with the traditional blue mold, which appears on old foods. 

Well, experts say yes, it’s okay to eat some products if you remove the affected part, as long as they are solid products, such as bread or cheese. In the case of soft products, such as cream cheese or jam (no, that’s not a flower, it’s mold!), it is not recommended to eat them.

The bottom line

In most cases, eating expired chips won’t make you sick. There is a high chance that you won’t like their taste and throw them away, tho. Chips contain a high amount of sodium (salt), making them have a longer shelf life. If you store them properly, they may taste the same even after one year. 

However, we do not encourage eating expired foods but smarter shopping. Do not buy too many chips if you already have some in the house and do not make a habit of eating expired food. Sometimes it is like playing Russian Roulette.
