The health benefits of coffee, is coffee good for health?

Caffeine, a stimulant

Coffee contains caffeine. Caffeine is a stimulant and acts on the entire central nervous system. Daily it is recommended not to exceed 400 milligrams of caffeine, which is the equivalent of four cups of filter coffee or six espressos.

Caffeine increases alertness and concentration. So it gives an energy boost. After absorption through the digestive tract, it quickly reaches the brain. There, the caffeine blocks the receptors of a substance responsible for calming the nervous system. As a result, it does not rest the brain and increases alertness. Hence the fight against drowsiness.

Some athletes are also coffee lovers. By stimulating the nervous system, caffeine improves wakefulness during exercise and delays the onset of feeling tired. An advantage for athletes! Of course, beware of overdosing in order not to have the negative effects of excessive consumption and choose a coffee without sugar.

Coffee, an ally against migraines

Thanks to its vasoconstrictor effect, some people also find that coffee can reduce the pain of migraines.

Against Parkinson’s and Alzheimer’s disease

In addition, for those who respect the dose of two to three cups a day, coffee reduces the risk of developing Parkinson’s disease. Studies have also shown that caffeine can protect neurons and affect several brain mechanisms responsible for the development of Alzheimer’s disease.

What consequences for type 2 diabetes?

Coffee may also play a role in the development of type 2 diabetes. High consumption may reduce the risk. For example, a meta-analysis of 200,000 people showed that drinking six cups a day reduced the risk of type 2 diabetes by 35%. So far, the mechanism of action has not been identified, nor the link between cause and effect.

Coffee, an ally against cholesterol?

In February 2022, a Canadian study looked at the role coffee plays in the fight against cardiovascular disease. Researchers assure that two to three cups of coffee a day contain enough caffeine to trigger a biochemical reaction that leads to a reduction in LDL cholesterol levels in the blood. In 2013, a meta-analysis found that those who drank three to five cups of coffee a day had a 15% lower risk of cardiovascular disease.

Coffee, good for the heart… but with caution

As for the benefits of coffee for coffee, the studies do not follow, but are not always the same. In August 2021, a study presented at the annual meeting of the European Society of Cardiology found that those who drank up to three cups a day reduced the risk of death from heart disease, stroke and premature death. A confirmed benefit in people without a diagnosis of heart disease. According to this study, the risk of death from cardiovascular disease is reduced by 17% and that of stroke by 21%.

So drink coffee, but in moderation. In September 2021, a study warned heavy drinkers. According to research by researchers at the University of South Australia, starting with six cups of coffee a day increases the risk of heart disease.

What influences the appearance of cancers? What effect?

In February 2022, an English survey assured that: drink three cups of coffee a day can reduce the risk of death by 15% if the coffee is ground. A risk that is even reduced by 25% for those who drink less than three cups. What about other types of coffee? As for decaffeinated coffee, more than three cups a day reduced mortality by 17%. These results therefore prove that the benefits of coffee are not just in the caffeine, other studies are needed to further explain the mechanisms of action and understand where the benefits come from.

No effect was observed in instant coffee lovers. Instant coffee contains more caffeine and antioxidants than ground coffee, but it also contains twice as much acrylamide, which has been shown to be neurotoxic and carcinogenic. This same study found a benefit against liver cancer. A disadvantage is that it is important to monitor the temperature of the coffee. Indeed, coffee drunk too hot can increase the risk of developing esophageal cancer.

A vitamin bomb

The coffee is an important source of soluble dietary fiber (19.8 grams per 100 grams of ground coffee). In addition, vitamin B3 (15 milligrams per 100 grams of ground coffee) in coffee is involved in the nervous system and the skin. Phosphorus (160 milligrams per 100 grams of ground coffee), also present in coffee.

Choose it right

Beans, ground or pod, coffee comes in a variety of forms and has something for everyone. While some prefer freshly brewed coffee beans that retain all their aroma, others swear by the usefulness of pods. Today, coffee comes in all flavors. From the classic espresso to the cappuccino – with a third of milk – through the latte or the mocha coffee – with a dose of chocolate, there is something for everyone.

And for those who prefer to drink it without caffeine, it’s also available in a decaffeinated version. There are two techniques for this. It is possible to use solvents to extract the caffeine or to resort to water and carbon dioxide. In all cases, the indication of the process used must be indicated on the packaging.

Arabica and Robusta, coffee identity card

Coffee belongs to the Rubiaceae family, it spread in Yemen in the 12th century, where it is then called k’hawah, which means “invigorating”. It arrived in Europe around 1600. Coffee is available all year round, the fruits are ripe six to eight months after flowering for Arabica and up to eleven months for Robusta.

In the world there are two types of coffee: Arabica and Robusta. The first represents 75% of the world’s production with a caffeine content of less than 1.3%. This variety, originally from Ethiopia, remains the most widely distributed with its mild taste. Robusta represents 25% of world production. Hardier – as the name suggests – is grown in West Africa and Southeast Asia.

Unlike its cousin, the caffeine content is higher, as it is usually between 2 and 2.5%. Regardless of the coffee, the technique remains the same as the beans are roasted to release the aroma of the coffee.

Know : the longer a coffee is roasted, the stronger the taste will be.

The storage method depends on the selected coffee. For ground coffee it is recommended to keep it in the refrigerator in an airtight container because it oxidizes quickly on contact with air. Roasted whole grains can stay at room temperature for several weeks.

Coffee preparation

The quality of the water is important to enjoy the full taste of the coffee. It is therefore recommended to use filtered water to avoid traces of limescale. With regard to the dosage, it is recommended to take between 3 and 6 cl of coffee for a cup of espresso. For those who like to add milk, try plant-based milks (e.g. soy or almond). There are also alternatives to sugar such as honey.

If you always think of your hot cup of coffee for breakfast or after dinner, try an iced coffee that will refresh your hot summer days. And, for the curious, coffee can also be used in a marinade for meat. To your recipes!

Why is coffee bad for your health? What are the risks?

While coffee can have many health benefits, excessive consumption has the opposite effect. Too much coffee – and therefore caffeine – disrupts concentration. But it all depends on individual sensitivity. Too much coffee can cause a loss of alertness, difficulty concentrating, increased hypertension and increased heart rate. Also be careful, the caffeine in coffee is added to the caffeine present in other needs such as soda, energy drinks and tea.

What are the contraindications for coffee? Is it good to drink coffee every day?

Coffee is not recommended for some people. Pregnant women should not abuse it. According to the World Health Organization (WHO), pregnant women should not consume more than 300 mg of caffeine per day, or about 3 cups of filter coffee.

Moreover, proof that nature is good, they are often naturally disgusted when they are expecting a child. In addition, coffee is not recommended for people who suffer from stomach ulcers because it stimulates acid secretion.

More information

Not all coffees have the same caffeine content. The one that contains the most is, unsurprisingly, espresso with over 100mg of caffeine. A 235 ml cup of filter coffee contains between 90 and 200 mg of caffeine. An instant coffee of the same capacity contains between 25 and 175 mg of caffeine.

Good to know : the longer the contact between coffee and water, the more caffeine the drink contains.
