Such conclusion has drawn international team of scientists from the University of Toronto, Harvard School of Public Health and the University of Costa Rica, after research with 4,028 Costa Ricans. Caffeine, which is a part of coffee, is transformed by means of liver enzyme cytochrome P450 1A2 (CYP 1A2). Depending on the version of a gene, which controls the work of these enzymes, the splitting of caffeine by different people can be faster and slower.

The study included 2014 Costa Ricans, who transmitted one myocardial infarction, and 2014 Costa Ricans, who do not suffer from heart diseases. All participants answered questions related to frequency of coffee consumption. They also carried out genetic tests to determine the specific variant of gene CYP 1A2.

Genetic tests have shown that «slow» variant of gene had 55% of people experienced heart attacks and 54% of people from the control group.

By people with «slow» variant gene, who drank 2-3 cups of coffee per day, the risk of myocardial infarction was 36% higher than those who drank less than 1 cup of coffee. With the use of 4 or more cups of coffee per day the risk of heart attack rose to 64%. People elder than 50 were in the most danger.

By people with «fast» variant gene, who drank up to 3 cups of coffee per day, the risk of heart attack was even lower than by people who used less than 1 cup per day, but with doses increasing this effect was not observed.

«One cup of coffee per day do not do any harm, not depending on genetic features», – considers the author of study Ahmed el-Sohemy. More coffee volume can be harmful or harmless, but people who do not know which version of the gene they have, the best of all would be to observe moderation

Ingredients
4 portions:

• 50 ml of strong coffee
• 50 ml of apple juice
• 2 tablespoons of brown sugar
• a pinch of mixture of 5 seasonings
• a pinch of ground cloves
• 2 sticks of vanilla
• 3 oranges
• a stick of cinnamon

Preparation
Put all ingredients to one pan and bring to a boil on the middle fire, then weaken the fire and leave for 10 minutes.

Pour mixture into the previously heated jug, then pour into cappuccino-cups and add in each cup a stick of vanilla.

• a cup of cold strong coffee
• a half glass of pineapple juice
• one ice-cream scoop
• some pieces of pineapple

Preparation
Mix coffee with pineapple juice and pour this mixture over the ice-cream scoop in the beaker or in the high glass.

Decorate with pineapple pieces, add straw or spoon with a long shank.

Ingredients

• 3 tablespoons of graham coffee
• 2 teaspoons of sugar
• 1 teaspoon of cinnamon
• 1 teaspoon of cocoa
• 1 teaspoon of anise seeds
• a pinch of dry orange peel

Preparation
Mix all ingredients and make coffee everyhow.

The special recipe provides the usage of French press.

• a bar of semisweet chocolate
• 4 oz of brown sugar
• 4 oz of ground coffee
• 2 sticks of cinnamon
• 3 pieces of cloves
• 8 cups of water

Preparation
Boil water in the Turkish coffee pot, and then add pieces of cloves, cinnamon, sugar and chocolate.

When the mixture begins to boil, take foam away. Turn the gas low and add coffee.

Let the beverage draw for 5 minutes before serving.

The scientists of The University of Barcelona have performed a research with 668 healthy volunteers. At first they were asked to drink coffee with caffeine and then without it. A cup of espresso, which was taken at the beginning, had a restorative effect already in 10 minutes.

By that, in order to reach maximum caffeine concentration in the blood, human’s body needs 45 minutes, but half of participants got concentration after just a few minutes.

The decaf coffee had a similar effect (exactly which contains 5mg of this substance). In both cases, researches have marked the most rapid effect achievement by men than by the weaker sex.

“The stimulant effect of caffeine has been proved by a numerous studies, but none of these have looked at their effects in terms of the consumer’s gender”, – said lead researcher Ana Adan.

“This study provides an interesting insight into how the effects of specific foods and nutrients may differ between men and women. Research into ‘gene-nutrient’ interactions gives more and more results. We can see how our genetic data affects our requirements for certain foods and nutrients, and how our bodies react to these. In the future this could allow scientists to formulate dietary recommendations based on our genetic data, as well as our age and body size”, – added Anna Denny from the British Nutrition Foundation.

In order to reach maximum caffeine concentration in the blood, human’s body needs 45 minutes, but for somebody just a few minutes will be enough.

Ingredients

• two teaspoons of freshly ground coffee
• ¼ glass of cognac (50 ml)
• 2 glasses of water
• sugar

Preparation
Put coffee into the coffee-pot, add hot water, and bring to a boil.

Pour out finished coffee into the cups, add cognac.

Serve sugar separately.

There are some main weaknesses. Foremost is of course a temperature. Do not try to do something until it is less than 92°C. Theoretically, if you put beans into the cool water, you will anyway get something restorative, however weak. The Japanese are working with temperature about 85°С, in European coffee-machines – 90-92°С, the Turks and Arabs have 96°С. The basis here, either to burn slightly coffee at the edges of the ibrik or to boil it for a long time. It is one of the examples of good spoiled coffee. By the way, ibrik is here the most successful variant. Just overboil it – that’s the easy part! In case of European and Japanese preparation methods, it may be arised some problems. It is not a reason to give up.

Because we have a powerful key factor as grinding. First, make it a bit crude and instead of flavored drink you will get clear water with a light smell. Second, the progress has placed at our disposal an excellent machine. We call itelectric coffee-grinder. Its high-speed gear burns beans to the best advantage. Make not big portions, put full speed and grinding time – and bitter coffee is assured.

• 2 tablespoons of freshly ground coffee
• 2 glasses of water
• 1/3 glass of milk
• ¼ glass of vanilla syrup

Preparation

Put coffee into the coffee-pot, add hot water, and bring to a boil.

Mix up hot milk and vanilla syrup, pour into the cups and add hot coffee.

Milan. The Nespresso Company has presented the collection of aroma candles «La Route des Cafés», which fill our homes with delicate coffee’s aroma.

The collection included 5 candles: Terre d’Arabica, Bois de Maragogype, Fleur de Moka, Grain d’Emeraude and Café Flambé. Each of them has its own specific coffee’s smell from different regions of the world.

The aromas were created by a perfumer Olivia Giacobetti. All candles are packed into the stylish small boxes and are available in the special Nespresso Boutiques.
