Is coffee healthy or not fitness knowledge

Is coffee healthy or is it harmful?

Coffee is the Germans' favorite drink. For many it is unthinkable to start the day without coffee. For centuries, the hot beverage has been drunk abundantly all over the world and on every occasion. The term "coffee derives from the Arabic word "qahwa. Means as much as stimulating drink. But how healthy is the brown broth actually? This is where opinions differ. We have gone to the bottom of exactly this question. Interesting results have been obtained.

Coffee and what's in it

We only know coffee as a source of caffeine. Coffee has a lot more to offer besides caffeine: Among other things, it contains various B vitamins, carbohydrates, fats, water, apparent proteins and vegetable acids. Alkaloids like caffeine, mineral and aromatic substances form the basis of coffee. The values of the ingredients differ depending on whether the proportions are measured in the raw material, in the roasted product or in the cup.

The caffeine content in coffee, however, is hardly changed by the roasting process. The preparation plays a major role in this: filter coffee, for example, contains significantly more caffeine than espresso. The lower caffeine content in espresso comes from pressing it with hot water, while in filter coffee the water passes through slowly, releasing more flavors and bitter compounds from the coffee powder.

A long and gentle roasting process is essential for good coffee. If coffee is roasted for too short a time, various bitter substances are formed that attack the stomach.

Effect of coffee

The effect of the substance in coffee is generally twice as long for women as for men. Children, young people and pregnant women react differently to coffee than older people. In smokers, for example, the concentration of caffeine in the body tends to decrease faster than in non-smokers. Taking medications also affects how and for how long caffeine works. Regular coffee consumption can lead to a habituation effect on the caffeine. But this is not comparable to cigarettes, alcohol or drugs. Our genetic predisposition influences how quickly caffeine is broken down in our bodies. Thus, each person reacts differently to coffee consumption.

This could also be partly why some people react to coffee with sleep, heart rhythm and circulation problems and others do not. Those who often sleep poorly anyway should either avoid coffee altogether or drink their last cup in the early afternoon at the latest.

Coffee myths

Over time, many myths and rumors have circulated about coffee – some complete nonsense, others not entirely untrue. We clarify.

– According to an old myth, cold coffee makes you beautiful. This can be traced back to the Baroque era, when a subtle pallor was considered the ideal of beauty. The face became correspondingly brighter. The lips made up red. The coffee was drunk cold, because hot coffee would have run the makeup. Regarding the present time this myth is of course total nonsense. – Coffee is diuretic only for those who drink it infrequently. Studies have shown that the fluid we excrete ca. The amount of caffeine in coffee corresponds to the amount we consume with coffee. So this rumor is also false. – One of the most widespread coffee myths is that coffee is unhealthy. On this point, science is not yet in complete agreement. There are about as many studies proving that coffee is unhealthy as there are studies proving the opposite.

What coffee can do

Those who drink coffee live longer. One reason for this could be the polyphenols contained in coffee, which have a good effect on cholesterol levels. The good cholesterol is increased. The bad lowered at the same time. The risks of arteriosclerosis. For a heart attack are lowered.

Because of its vasodilatory effect, which causes the heart rate to drop, the caffeine in coffee can even have a calming and concentration-enhancing effect. It is also used pharmaceutically for headaches, asthma and heart failure. Coffee has a stabilizing effect on the concentration of the neurotransmitter dopamine. Coffee drinkers are statistically less likely to get Parkinson's disease.

The chlorogenic acid contained in coffee also possibly prevents colon, prostate and liver cancer. The chlorogenic acid can also have a positive effect on insulin metabolism. For a diabetic patient it can be good to have a cup now and then.

How much coffee is healthy?

The evaluation of a total of 36 studies from Singapore and the USA have shown that people who drink between 3 and 5 cups of coffee a day are less likely to suffer a heart attack or stroke than those who do not drink coffee at all. According to the study, women who drank 2 – 3 cups a day had a 25% lower risk of dying from cardiovascular disease. In the case of cancer and heart disease, the risk of death among female consumers fell by 18.

Other studies from Brazil found an increase in sperm activity. The coffee additionally provided for an increased desire. Additional stimulation of manhood.

In addition, numerous studies have also shown that coffee drinkers are particularly sexually active. However, women have been found to have reduced muscle activity in the fallopian tubes, which in turn may reduce fertility.

Lose weight with coffee

Coffee can also help you lose weight. The caffeine ensures that our metabolism gets going, this stimulates the central nervous system and stimulates the fat burning. This fat burning breaks down both dietary fats and body fats, making them easier to break down.

Losing weight with coffee works best if it is drunk black, without sugar and directly after a meal. Coffee alone should not be used for dieting. This would only lead to the yo-yo effect or health problems. It makes sense to include coffee in a diet plan with sufficient vitamins, nutrients and fluids (in the form of water and unsweetened teas), sports and exercise.

The dose makes the poison

Coffee in normal quantities definitely brings positive effects. The emphasis is on "normal amounts, because: Coffee in masses has a negative effect on the body. This can manifest with anxiety, irritability, mood swings, sleep disturbances, depression and exhaustion, for example. If you keep your body constantly at a high level of caffeine, you are permanently in a physical stress situation. To avoid this, everyone should find out for themselves the tolerable amount. A rule of thumb for healthy coffee consumption is no more than 3 cups a day of!
