How much coffee can you drink before you die?

In this text we will provide the answer to the query: “How much coffee can you drink before you die?”. In addition, we will discuss the symptoms of caffeine overdose and the safe daily amount of caffeine to drink.

How much coffee can you drink before you die?

The lethal dose of caffeine is approximately 10 g, which corresponds to about 28 large cups of coffee. Caffeine is a stimulant substance present in many products such as coffee, tea, soft drinks, energy drinks, supplements and even medications.

Caffeine powder is generally used by the industry as a raw material for products containing the product. Coca-Cola, for example, uses 34 mg of pure caffeine (about 1/64 of a teaspoon) to produce a 350 ml can of the beverage.

In any organism, the ingestion of more than 20 cups of coffee a day can cause digestive and cardiac alterations. However, the toxic dose of caffeine will vary according to age, weight and even diet. 

In the case of powdered caffeine, for example, if the person is fasting before ingesting it, the compound will be absorbed much faster, which can increase the risk of overdose. In any case, regardless of these factors, it is not recommended to consume more than five cups of coffee daily or the equivalent in other caffeinated beverages.

What are the symptoms of caffeine overdose?

Symptoms of a caffeine overdose can include a rapid or dangerously erratic heartbeat, seizures, and death. Vomiting, diarrhea, lethargy and disorientation are also symptoms related to caffeine toxicity and they tend to be more severe than when related to excess coffee, tea or caffeinated beverages.

Caffeine is a xanthine that acts on the central nervous system to improve neurotransmitter response, causing insomnia and psychomotor agitation. However, it also affects the heart and respiratory system and, in high doses, stimulates the production of secretions from the gastrointestinal tract, such as hydrochloric acid. 

Thus, excess caffeine increases respiratory and heart rate, which can lead to cardiac arrhythmia, in addition to increasing the risk of gastritis and other gastrointestinal problems.

What is the safe daily amount of caffeine to drink?

The safe amount of daily caffeine consumption varies between 4 to 5 cups of coffee, which corresponds to approximately 400 mg of caffeine.

It is difficult to establish a daily consumption limit precisely, because caffeine is eliminated from each body in different ways. The variations are a result of genetic differences, gender, and even whether a person is a smoker.

To add to the confusion, science loves coffee. And it’s no wonder – not only does it keep you awake and in the mood for hours, it can make you live longer, lower the likelihood of developing prostate cancer, lower your risk of depression and protect you against heart disease.

If you love coffee too, a few cups won’t kill you – you can only get close to it if you drink a gallon of it. Drinking up to four or five cups of coffee a day, which is equivalent to 400 mg of caffeine, is a safe amount for healthy adults.

The caveat is for pregnant women, who shouldn’t consume more than 200 mg of caffeine a day, or two cups of coffee. Recent studies indicate that high caffeine consumption by pregnant women is linked to a higher risk of miscarriage or having an underweight baby.

What are the benefits of caffeine?

Caffeine offers several benefits to those who consume it and to the body in general. Discover the main ones:

Stimulant effect

The stimulating effect of caffeine improves mood and concentration, prevents sleep and can be interesting for people who need energy, whether for work or physical activity.

Increases basal metabolism

Faster metabolism tends to burn more calories, which can be beneficial for the weight loss process.

Ergogenic resource in sports practice

During physical activity, caffeine delays fatigue, has a stimulant effect and increases performance in strength and aerobic exercises.

Increased lipolysis

Caffeine can increase the use of fat stores as an energy source, sparing the use of glycogen and increasing fat oxidation. This effect occurs mainly during physical exercises and is interesting for those looking for muscle definition.

Increase in muscle strength

Because it has a direct relationship with the central nervous system, caffeine increases the release of noradrenaline and adrenaline. This factor may be responsible for delaying fatigue and increasing muscle strength, making it possible to perform exercises with greater loads and repetitions.
