Can coffee make you sick?

In this text, we will provide the answer to the question: “Can coffee make you sick?”. In addition, we will discuss whether coffee is bad for health or has health benefits. In addition, we will explain to you the ideal dose of coffee.

Can coffee make you sick?

No, coffee can not make you sick. Coffee isn’t bad unless you overdo it and consume more than 400 mg of caffeine a day (between 3 to 4 cups of coffee). It is only when you overdo it that it is possible to have some unwanted side effects such as tachycardia, difficulty breathing, anxiety and tremors.

One factor that can make coffee make you sick is the fact that it has mycotoxins. These substances are produced by fungi. However, not all fungi will produce mycotoxins in coffee. However, the most ideal thing is that the coffee contaminated by these microorganisms is discarded. 

The problem with mycotoxins is that they are not eliminated during washing or roasting, remaining in the roasted coffee. And they can bring harm to your health. So, make sure you are drinking quality coffee.

In addition, coffee may contain acrylamide, a carcinogen that can be produced during roasting by the Maillard reaction. This reaction occurs in any food that contains reducing sugar and protein or amino acid at high temperature. 

However, there are other foods that have much higher amounts of this substance. So, coffee is not the biggest problem when it comes to acrylamide consumption. However, if you drink moderate amounts of coffee, don’t worry about overdosing acrylamide from coffee. 

Also because if you consume too much coffee, you can have other negative effects due to excessive consumption of caffeine.

What are the recommended doses?

The maximum recommended daily dose of caffeine is around 400 mg of caffeine, that is, a maximum of 5 cups of coffee a day or 3 espressos. In addition to coffee, we must count on the caffeine present in other foods that we consume daily, such as teas, soft drinks and chocolates.

We must also remember that some medicines have caffeine in their composition, so we must always keep our body’s caffeine levels below 400 mg per day or a single dose of 200 mg.

Is it possible to get food poisoning from coffee?

Food poisoning from coffee is unlikely to occur, as roasted coffee does not have favorable conditions for the growth of bacteria and fungi. However, green coffee already presents a very favorable environment for the growth of fungi.

It is very difficult to be intoxicated by coffee since the coffee is roasted and its amount and activity of water is very low, which does not favor the appearance of bacteria, fungi, among other microorganisms.

Although it is very rare to happen, this intoxication comes from the bad storage of grains in the silo.

What does coffee do to your body?

Once caffeine enters your bloodstream, about 40 minutes after ingestion, it significantly improves your exercise performance as it acts as a stimulant for the body. Thus, it performs the blockade of adenosine in the brain and once adenosine is blocked, greater brain functioning occurs, improving fields such as concentration and memory.

Moderate consumption of this substance has long-term effects on memory, concentration, focus and disposition. However, excessive consumption of caffeine is linked to worsening symptoms such as panic syndrome, anxiety and can be harmful to having a good night’s sleep.

Is instant coffee bad for you?

No, instant coffee is not bad for your health. Although popular belief and some observational studies show that soluble/instant coffee is harmful to your health, instant coffee is not bad for you.

Its consumption convenience is undeniable, but instant coffee has been increasingly appreciated for its quality as well, as it has evolved a lot since its discovery. 

Nowadays it is possible to find instant coffee versions 100% made of Arabica coffee in its coffee extract composition, with all the sensory characteristics of the beans preserved. As a result, the product is very similar to fresh coffee in flavor and aroma.

One of the many benefits of coffee is that it has low calories, analgesic and stimulant properties, in addition to the high concentration of antioxidants, making the habit of drinking coffee help in brain functions. As a result, brewed coffee in beans or ground (fresh) and instant (soluble) share the same market side by side, in worldwide preference.
