What Happens to Your Body if You Eat Expired Foods

How effective are expired foods? I bet your answer is, “I don’t know.”

Can I be frank with you?

Eating expired foods is unavoidable.

For example, let’s say you often pick up a random packet of food from the market and then take it home to eat. 

Later, when you read the details on the packet, you find out that it was expired. 

Or you don’t bother to read the expiration date on food and end up eating it.

So what now? 

What will happen to your body if you have eaten expired food? 

What should you do if you have eaten expired food? 

You must know answers to all these questions because it is very important for the health and safety of yourself and others.

Having said all that…

Now, I’ll tell you what will happen to your body if you eat expired foods.

Ready? Let’s get to it.

1. You’ll be fine if you eat expired foods. 

The best thing that can happen if you eat expired food is that you’ll be fine, and nothing will happen at all. 

But that doesn’t justify that you start eating every expired food out there as it can be too dangerous.

But for the sake of clarity…

Allow me to explain:

Most of the time, the expiry date of a food refers to the fact that this specific food will be best in taste and quality till this date. 

It has nothing to do with the safety of that food. 

That’s why we often see lines written like “use before” and “best before,” etc. 

Once that date passes away, the quality and taste of that food do not remain the same as before. 

It may become smelly or bad in taste, but you will be pretty much fine if you eat it.

Especially if you had stored the food the right way, then there’s nothing much to worry about. 

For example, the canned food that you froze in the freezer for days will be completely safe to eat even a week after the expiry date. 

Why? Because when food is frozen, it remains completely dry and safe from harmful bacteria and germs. 

However, its taste, smell, and quality may change, but it’ll be safe to eat.

2. You could experience food poisoning if you eat expired foods

Food poisoning is a rapidly growing condition all across the world that is caused by consuming expired foods. 

Here’s the thing: 

Expired food may get spoiled and contains many molds, harmful fungus, bacteria, and toxic materials that cause food poisoning in your body.

The symptoms of food poisoning include:

  • Intense fever
  • Diarrhea
  • Vomiting
  • Abdominal pain

However, it’s important to note that…

Apart from eating expired foods, food poisoning is also caused by eating uncooked and raw food.

The bottom line here is: If a food has developed mold spoilage, it should not be eaten.

3. You’ll be exposed to dangerous bacteria if you eat expired foods

Eating expired foods can have different consequences depending upon the case and what kind of expired food you have eaten. 


As I mentioned earlier, the best thing that can happen is that you’ll be completely fine or suffer from mild food poisoning. 

However, the worse thing can be extreme food poisoning and exposure to extremely dangerous bacteria.

In fact, when some foods pass their expiration date, their quality starts spoiling and deteriorating due to attacks by fungus and bacteria. 

For instance:

If you eat any such food infected by dangerous bacteria like E. coli, salmonella, cholera, shigella, staphylococcus aureus, etc., then you’ll be at a great health risk.

Such dangerous bacteria enter your body and lead to many serious diseases, infections, and even death. 

In addition to that, they can attack your stomach, nervous system, kidneys, liver, and brain and cause severe infections that can take your life.

Be aware: Expired foods may contain dangerous harmful bacteria.

4. You won’t get enough nutrients

Let me make something clear…

Most of the time, the expiration date of food means that this food will be best in taste, smell, quality, and nutrition before the expiry date. 

After that, the food quality starts deteriorating and starts losing its nutritional value and benefits.

In other words, if you keep eating such food, it will not only cause certain diseases.

But also deprive your body of all the healthy nutrients needs to boost your immune system

Eventually, your body will become weaker and become vulnerable to more health problems.

The bottom line is this: Some expired foods may reduce the amount of nutrients they retain.

I have eaten expired food; what should I do now?

If you have mistakenly or intentionally eaten expired food and are now worried about your health, don’t worry. 

Take it easy because there are good chances that you’ll be completely fine.

But one thing’s for sure, eating expired food cannot kill you…

Nevertheless, carefully watch out for any symptoms of food poisoning and illness. 

However, if you experience any of the symptoms, then immediately visit your doctor without any delay. 

Tell them about your exact condition so they can give you appropriate treatment.

Final thoughts

Eating expired food has different consequences for your body in different cases. 

Sometimes, you will be completely fine and get away with eating expired food, and sometimes you may suffer from mild to extreme food poisoning and other dangerous diseases.

Therefore, we recommend you avoid eating expired food as it can create severe health problems for you.
