Coffee was once considered to be the devil’s drink, its properties were appreciated only by Pope Clement VIII, and at that time also gained well-deserved publicity.
Nowadays, the most popular species are Arabica and Robusta, which in turn are divided into many varieties. Coffees differ almost everything – from the place of origin, character or shape of grains. Arabica is the oldest and the most popular coffee that mastered the world in terms of production in 70%. Its grains are oblong, flat and slightly greenish with a curved seam. The obtained coffee is mild and aromatic, but we can also meet types with flavored additions. The delicate smell is accompanied by a fairly low caffeine content ranging from 1 to 1.7%. The second most popular species is Robusta, characterized by a sharp and bitter taste. The shape of the grain is round, the seam is straight and the color is pale green, sometimes even gray. It is accompanied by a stronger concentration of caffeine in the range of 2-4,5%, and its production in the world reaches almost 30%.
The third species is Liberik coffee, whose production does not exceed 1% due to the uneven development of berries. At the same time, ripe and unripe berries can be found on the coffee plant, so growers rarely decide to grow this species. The most expensive coffee in the world is coffee luwak, whose cup costs almost PLN 100, and its grains are selected from indonesian manure, shelled muzanga, which only eats the best coffee.
Coffee health properties
The reason why coffee has so many devotees is caffeine, because of this we do not realize what is still valuable in itself. We find antioxidants in the form of chlorogenic and coffee acids, salts responsible for the binding of important elements (eg calcium, potassium, magnesium, phosphorus, iron, sodium, zinc, copper, cobalt, nickel, manganese, chromium) and B group vitamins, organic acids: formic, acetic, glycolic and lactic. Coffee grain is also rich in fatty acids, essential oils or proteins, carbohydrates and fiber.
One of the most important medicinal properties of coffee is to support weight loss by improving metabolism and fat burning associated with it.
Increases thought processes by affecting the central nervous system and accelerating the flow of electrical impulses in the brain. Facilitates concentration, improves short-term memory, and absorption from the digestive system begins just after 15 minutes after drinking a cup of coffee, while its highest concentration is felt after about 3 hours.
Studies show that it lowers the concentration of histamine – a substance involved in allergic reactions, whereas the fact that it widens the bronchus causes a decrease in the frequency of dyspnea attacks.
Thanks to strong antioxidants, it neutralizes dangerous free radicals, and also facilitates the elimination of toxins from the body, contributing to the improvement of defense mechanisms. It protects against certain cancers.
Recent research has also shown that moderate coffee consumption can lower the development of Alzheimer’s disease and reduce the risk or delay the onset of Parkinson’s disease.
Coffee beans are very much sought after by the cosmetics industry because of their anti-aging properties. Caffeine has long been used in all cosmetics that prevent the formation of wrinkles, has antibacterial and anti-inflammatory properties. The polyphenolic compounds present in coffee, and above all polyphenolic acid, prolong the dissolution of vitamin C, which smooths the skin’s unevenness and counteracts the appearance of others. It is also beneficial for circulation, hence occurrence in eye creams.
In the fight against cellulite, peeling made from coffee brewed earlier helps. Do not pour out the grounds, just add to them, for example, shower gel and massage the mixture into the skin of the whole body or only places controlled by orange peel. Often, some olive oil or sugar with large crystals are also added to the coffee grounds, but the most important is the slightly mushy consistency.
Coffee obtained from roasted wheat grains, often with the addition of chicory or sugar beet, which tastes similar to the taste of natural coffee. It is recommended for people who, for health reasons, can not drink coffee containing caffeine.
Cereal coffee, although it is decaffeinated coffee, has stimulating properties thanks to carbohydrates, which have a positive effect on the human brain. It is recommended for slimming people, children, pregnant and nursing women, as well as people with heart disease or stomach and duodenal ulcers. Cereal coffee does not cause addiction and as natural coffee does not prevent the absorption of such valuable mineral salts as iron or magnesium – so it can be consumed by women during menopause.
It can be safely called a diet drink, because 100 grams of cereal coffee without any additives conceals from 5 to 50 calories, depending on the composition of the products from which it was made.
The most famous grain coffee with a delicate flavor gained its popularity thanks to its natural ingredients. Rich in nutritious nutrients, produced from grains of barley, rye and valuable chicory. Due to its low calorific value – one cup of Inca coffee supplies only 14 calories – is an alternative to people who are slimming. It is worth mentioning the beneficial effects of chicory, which, thanks to the inulin, reduces the energy value of the meals consumed.
We hear from the media that it is a great replacement for caffeinated black coffee, while scientists have divided opinions. Green coffee, it is really well known to us black coffee, but before the heat treatment, unroasted.
A popular opinion is that green coffee improves metabolism but what about all dietitians? They are skeptical about the big boom caused by the media. Joe Vinson, a chemist at the University of Scranton in Pennsylvania, believes that the publicity of coffee has brought the chlorogenic acid contained in it, which occurs in coffee and artichoke, shred or plums. This acid reduces the level of sugar absorption, and thus allows the active burning of accumulated fat in the body. Can you trust the research that has been carried out on a group of people who have been drinking green coffee, followed the principles of healthy eating and implemented physical training under the supervision of experts? A study conducted by Joe Vinson carried out a study on 16 people (8 women and 8 men), and as a result, an average of one person dropped 8 kg. Research has shown that when changing the lifestyle, coffee will help slimming, but it is still unknown which ingredients have slimming properties. . Drinking green coffee alone will not solve the problem of being overweight.
Studies were also carried out which were published in the „Journal of Agricultural and Food Chemistry”. It results from them that chlorogenic acid can cause so-called metabolic syndrome, and this is nothing but a combination of combined elements that cause an increase in the development of atherosclerosis and type 2 diabetes and their vascular complications.
Little known coffee soluble from spelled grains is a perfect complement to rational eating. This ecological drink without caffeine, thanks to its health properties can also be consumed by children.

It strengthens sense organs, slows down the aging process, and regular use promotes the regeneration of the whole organism.
Usually, scientists are asked about the recommended dose of coffee consumption, that the amount of up to 500 mg of caffeine per day is not harmful, and it can also positively affect the body. Remember, however, that the coffee will wash out magnesium from the body, which we should supplement.
Each coffee has its own supporters and opponents, so it is important to match the best to your expectations. One thing is certain – caffeine has a stimulating effect on people whose body is not accustomed to its properties, and for people who can not drink it for health reasons, decaffeinated coffee is an excellent alternative. It’s good that we have a choice.
