What happens if you drink a can of coffee?

Coffee composition

The lower the temperature and duration of roasting coffee beans, the more beneficial properties are preserved. The composition of a drink can be assessed in two categories - its value (nutrients, beneficial microelements) and chemical elements.

Nutritional value (no sugar, cream):

• Fats – 0.7 g;
• Proteins – 0.2 g;
• Carbohydrates – 0.15 g;
• Vitamin PP – 0.5 g;
• Potassium – 0.5-0.9 g;
• Phosphorus – 7 mg;
• Calcium – 5 mg;
• Iron 2-3 mg.

Coffee is low-calorie, with no more than 9 kcal per cup. But on the other hand, it can replenish 20% of the daily requirement of vitamin PP and is a rich source of potassium.

The chemical composition contains over one and a half thousand different elements. Of these, less than half have been studied so far, so coffee will remain an object of research for a long time.

Due to roasting, beans lose a quarter of their moisture; during processing, most of the lipids are lost.

What does it consist of:

• Sucrose, fructose, galactose;
• Organic acids - malic, pyruvic, acetic, caffeic, oxalic, citric;
• Essential oils. They have an antiseptic effect and add aroma;
• Caffeine;
• Trigonelline. Responsible for the richness of taste and pleasant smell;
• Cafeol.

What to do if you overdose on coffee

When poisoned with an invigorating drink, a person’s heart can stop, which will lead to death. To remove an excessive dose of caffeine from the body, basic procedures are required.

Treatment for humans:

1. Drink 2 to 3 liters of clean, still water. Caffeine leads to dehydration. To prevent the release of moisture from the body, you need to add 1/2 to 1 teaspoon of table salt per 1 liter of water.
2. Place the patient in a horizontal position, providing access to fresh air into the room. This way you can get rid of attacks of nausea and dizziness.
3. To reduce your heart rate, it is recommended to eat a banana. The fruit contains a large amount of potassium, which has a beneficial effect on the functioning of the cardiovascular system.

For severe symptoms, treatment is carried out by a doctor. Otherwise, the risk of developing pathologies and death increases.

The benefits and harms of coffee

It provides great benefits with its antioxidants and minerals. But when overdosed, coffee causes no less harm than when it is consumed for contraindications.

Three to five leads to:

• Depression;
• Fatigue;
• Drowsiness;
• Sudden mood swings;
• Irritability and aggression.

Coffee constantly stimulates the nervous system, keeps it in tension, which causes it to become exhausted.

The drink does not replenish fluid deficiency, but serves as a diuretic that dehydrates. Therefore, after a cup of coffee it is customary to drink one or two glasses of water.

If you do not have heart problems, then it will not harm you in any way. The only short-term effect of the drink is an increase in blood pressure, which almost immediately returns to normal.

It greatly affects the functioning of the gastrointestinal tract, increasing the level of acidity in the stomach; an overdose of coffee can cause the development of peptic ulcers and gastritis. Doctors and nutritionists all unanimously say that drinking it on an empty stomach is not recommended.

Coffee contraindications:

• For cardiovascular diseases;
• For nervous disorders and mental disorders;
• In old age and childhood;
• During pregnancy.

Benefit:

• Mitigation of asthma attacks, allergies;
• Helps get rid of toxins, improves the condition of patients who are rehabilitating from alcohol and drug intoxication;
• Decreased blood pressure;
• Increased brain activity, increased performance;
• Reduces the risk of Alzheimer's disease;
• Prevents the development of ovarian cancer in females;
• Reduces the risk of liver disease and oral cancer.

The ambiguity of the drink raises the question - is it possible to die from it? Yes, if the daily intake of caffeine is 10 grams, which is contained in 5-30 liters of drink.

Poisoning with natural and instant coffee

Natural coffee poisoning usually occurs due to an overdose. As an option, if a person usually drinks a weak instant drink, and then decides to drink a large cup of a strong natural one.

It is much easier to get poisoned with instant coffee. It is processed chemically, and the finished powder or granules usually contain up to 15-20% of the original grains. The rest is stabilizers, preservatives, emulsifiers, dyes, starch, synthetic additives, etc. The cheaper instant coffee is, the more dangerous it is to drink, since there is less and less natural product and more and more chemicals.

Decaffeinated coffee is also unsafe. Caffeine is washed out with chemical solvents, which are also present in minimal doses in the finished product. If the coffee is instant, it also contains all the dyes and preservatives described above.

Most often, people get coffee poisoning due to an individual reaction to artificial components or a combination of them. Therefore, you should not get carried away with an instant drink from an unknown brand if you are prone to allergic reactions or have diseases of the cardiovascular system.

You can get poisoned if you usually drink coffee with milk and suddenly drink black coffee.

What dose is safe?

Scientists were unable to establish the exact norm. Everything is conditional - the type of roasting of coffee beans, the type (ground, instant), the individual characteristics of a person - force it to constantly change.

But there are conditional limits. An overdose can occur due to the use of 25 servings of natural and 15 servings of instant. In this case, the amount of caffeine received by the body per day should exceed 100-150 mg of caffeine.

But it is best to limit yourself to 1-3 servings, which will not harm the body due to the high caffeine content.

Symptoms of coffee overdose

Symptoms of coffee overdose are conventionally divided into three phases: early, late, acute.
