Introduction.

It became interesting for us to find out whether chocolate is harmful or useful and we decided to find out. Here's what we got.

What is chocolate?


  1. Translated from Latin, the word "chocolate" is translated as "food of the gods."

  2. And translated from the Aztec word "chocolatl" - (the name of the drink of cocoa beans) is literally translated "bitter water".

  3. Well, translated from Mexican "chocolate" is a confectionery product made from cocoa beans with the addition of sugar, cocoa butter and vanillin.
Chocolate favorite treat children and adults. The debate of scientists about the dangers and benefits of chocolate continues until today. Both supporters and opponents of chocolate have weighty arguments. Yes indeed; Some experts believe that cocoa butter protects teeth from decay. Well, others, on the contrary, are of the opinion that chocolate, like all sweet things, is bad for teeth.

We all really like this delicacy and we wanted to know:

1. How did he come to us?

2. What was it made from?

3. What is chocolate like?

4. Is it true that teeth deteriorate from it?

5. Why can't you eat a lot of it?

6. And in general, how bad is chocolate?

Main part:

1. Questioning.

I love sweets, especially chocolate. But they constantly tell me that you can’t eat a lot of it, that your teeth deteriorate from it, and in general there is nothing good in it.

I asked my mom about chocolate. She answered like this: - Chocolate is useful, but only in small quantities. It can be eaten every day, but a little bit. Since chocolate is a source of energy and contains many vitamins, it improves mood, strengthens the immune system and has a good effect on memory.

We also decided in our study to find out how the children of our school relate to chocolate. We asked students different ages and here's what happened...

Questionnaire:


  1. Do you love chocolate?
Yes 37 No 3

  1. Do you think chocolate is bad?
Yes 18 No 22

  1. Do chocolate spoil your teeth?
Yes 35 No 5

  1. Do you know where chocolate came from?
Yes 18 No 22

  1. How often do you eat chocolate?
Every day 16 Once a week 16 Once a month 8

  1. What kind of chocolate do you like?
Porous 11 Bar 11 Plain tiles 18

Thanks to our survey, we concluded that chocolate is a favorite treat for children and adults, but little is known about it. For example, almost no one knows where he came to us from. We decided to fix this and introduce you to the history of chocolate.

2. The history of the origin of chocolate.

The history of the origin of chocolate began a very long time ago, more than three millennia. Cocoa fruits were still used by the American Indians (native Americans who lived a thousand years BC).

At the beginning of 16 Christopher Columbus brought cocoa beans to the king from which they made a chocolate drink. Ordinary tiles appeared only in the middle of the 19th century. Bar-shaped chocolate has become the most popular.

The cacao tree is an evergreen plant that grows only in warm and humid climates, mainly in North and South America, Australia and some islands in Asia.

Its hard fruits look like melons, each fruit contains from 20-40 seeds laid in rows, they are called cocoa beans, although they have nothing to do with real beans.

3. Types of chocolate.

Nowadays, there are several types of chocolate: milk, white, porous, diabetic, black (bitter), dark chocolate in powder.

Ordinary or classic chocolate- this is chocolate with a content of cocoa products from 35 to 55-60%. But in bitter chocolate, the content of cocoa products exceeds 55%.

Bitter chocolate is considered the most useful, since it contains the maximum cocoa products.

Chocolate is a product that contains cocoa products. Cocoa products include cocoa mass and cocoa butter, which are made from cocoa beans.

One cocoa fruit contains 50 cocoa beans. It takes 90 cocoa beans to create one chocolate bar. And on one cocoa tree, 40 cocoa fruits grow. As a result, only 16 chocolate bars are obtained from one cocoa tree per year.

4. Control purchase and its results.

In our newspaper, issued specifically for the project, an examination of milk chocolate was carried out and a general assessment of such chocolate was given as:


  1. "Sweet Island"-this chocolate turned out to be with a not quite homogeneous structure, not melting in the mouth, with a sugary-sweet aftertaste.

  2. "Russia is a generous soul"- this chocolate turned out to be excellent composition and taste.

  3. Dove - this chocolate with bright and gentle taste.

  4. "Alenka" - this chocolate with an excellent composition, but an unusual taste for us since childhood.

  5. "Alpen Gold" - good composition with a sickeningly sweet taste.

  6. Milka - not cloying and not obtrusively sweet and even mild taste.
And we held our tasting at school and invited the children to try and choose two flavors of milk chocolate they liked. IN test purchase chocolate involved:

No. 1 "Alpen Gold"

№2 "NESTLE"

No. 3 "Alenka"

№4 "RITER SPORT"

As a result of the examination, it turned out that the children of our school liked milk chocolate under numbers 1 and 4 more.

5. Interview with a rural paramedic.

We noticed that when asked, “Does chocolate spoil your teeth?” opinion was divided, even adults answered differently. But most people think so.

In order to still find the truth, we went to our rural hospital. There we managed to talk with the ambulance paramedic Anna Vasilievna Anikina, whom we asked questions of interest to us:

Question: Please tell me, is chocolate harmful or beneficial for the body and how much can you eat without harm to health?

Answer: From a medical point of view, chocolate is useful product for a young developing organism. Since it does not contain a large number of caffeine, sugar, and most importantly, a huge energy reserve, which has a positive effect on mood.

Question : What are the health benefits of chocolate?

Answer : Chocolate is not only a delicacy, but also a wonderful healer. In epidemics of influenza and SARS, you can lubricate the nasal mucosa with cocoa butter, which will protect against infection attacks. With a strong cough, an expectorant is better. Chocolate contains iron, which increases blood hemoglobin. The carbohydrates contained in its composition help to quickly restore strength.

Question: Do you think chocolate damages teeth?

Answer: It has long been thought that chocolate destroys tooth enamel, but this is not true. The composition of cocoa beans includes antibacterial components that prevent the occurrence of caries.

Question : Can all people consume chocolate without harm to health?

Answer: No people prone to promotion blood pressure and people prone to obesity chocolate is contraindicated.

Question : What advice can you give to children?

Answer: Eat chocolate daily, but in moderation no more than 1/3 of a bar per day. Otherwise, chocolate can harm the body.

After listening to the conversation of the doctor, we made the following conclusions:


  1. Chocolate is the culprit of excess weight, as it is a high-calorie product and when consumed in excess, carbohydrates are deposited in the body in the form of fat.

  2. Chocolate with unrestrained eating can cause allergies, resulting in diathesis, so it is not recommended to give it to children under 2 years old.

  3. Chocolate has a stimulating effect. It should not be eaten a lot at night.

  4. Chocolate is a source of energy, it contains potassium and magnesium, which are necessary for muscle function. Therefore, chocolate is useful for children and those involved in sports.

  5. Chocolate is good for the heart and blood vessels. Cardiologists have found that dark chocolate prevents the formation of blood clots on the walls of blood vessels, improves blood flow, heart and brain function.

  6. Chocolate cheers up, its aroma causes pleasure and pleasure.

6. Interesting facts.

At the end of our study, I would like to introduce you to interesting facts about chocolate. We have prepared for you a newspaper in which it exposes a lot of misconceptions about him.

Did you know that International Chocolate Day is celebrated around the world on July 11th.

The most "chocolate" countries in the world are Belgium, Switzerland, Italy, France and the USA. It is in these states that the population consumes great amount chocolate. And the confectionery traditions of Belgium and Switzerland are considered the best in the world.

White chocolate was invented by the great Henry Nestle from Switzerland. The confectioner simply added condensed milk to the finished chocolate mass.

Every year people eat more than 600 thousand tons of chocolate.

In Russia, the first monument to chocolate was made, which was opened in the city of Pokrov, Vladimirov Region, on July 1, 2009.

For our smaller brothers, chocolate is poisonous, since the substances contained in chocolate are digested with difficulty. That's why safe dose for humans, can be fatal for pets.

Conclusion.

Is chocolate good or bad? We put forward a hypothesis and it was confirmed that chocolate has a beneficial effect on human health and well-being.

We found that both the benefits and harms that a person receives from chocolate can be different.

They say that everything that is not tasty can be useful, and tasty can be harmful. And we introduced you to a product that is both tasty and healthy.

Eat chocolate in moderation!

Research phase

Before starting work on the project, we decided to study the literature on this topic and acquaint everyone with the results of our work.

History of chocolate

In fact, the history of chocolate began over three thousand years ago. It was on the shores of the Gulf of Mexico in America that the Olmec civilization arose. Linguists attribute the origin of the word "cacao" to this people, which among the Olmecs sounded like "kakava". The Olmecs were later replaced by the Mayan civilization. They learned how to make a chocolate drink from cocoa beans, which they considered sacred.

In Africa, on the Gold Coast, under the shade of huge coconut palms, small plump trees are hiding from the scorching tropical sun. On their elastic, strong branches, fruits similar to bright yellow cucumbers hang in bunches. Parrots and monkeys are very fond of feasting on them. If you remove the delicate bizarre fruit and cut it open, you can see rows of yellowish seeds. Each seed is the size of a large bean. These are cocoa beans. In the tropics, these trees grow almost everywhere. And although the birthplace of cocoa is Mexico, the largest cocoa plantations of theombora in Africa. Do you know how the name "theobroma" is translated? - "Food of the gods". And this tree itself was revered as divine by the ancient Indian tribes. The Aztecs, for example, worshiped the chocolate tree. They made from his seeds wonderful drink, which restored the strength of a person. In addition, it was unusually sweet and fragrant, indeed. divine drink! The Aztecs also used cocoa seeds instead of money. Cocoa seeds were also used as a substitute for money. "Take a hundred seeds, and give me a slave!" said the rich Indian. "I'll buy a rabbit from you!" - said another, poorer, and held out ten seeds. Seeds could pay taxes.

For many centuries, chocolate was consumed as a drink - the Indians mixed ground and roasted cocoa beans with water, and then red pepper (chili) was added to this mixture. In Europe, the first cocoa beans appeared thanks to Christopher Columbus, the inhabitants of Guyana wholeheartedly regaled their dear guest with a drink made from cocoa beans. Returning from the expedition, he presented cocoa beans to the table of the Spanish king. After some time, cocoa beans appeared at the court of the king of France, and then spread throughout Europe. The new delicacy quickly became popular among the nobility. Europeans prepared a chocolate drink by adding milk, sugar and vanilla to it. Unusual and extraordinary delicious drink was exceptionally expensive, and only members of the nobility could afford it.

In the 17th century, scientists first discovered medicinal properties chocolate, which further increased its popularity. Chocolate was recommended as a cure for many diseases, it was considered a means of promoting longevity.

In the 18th century, the first pastry shops opened in France, where visitors were treated to a chocolate drink. And in England, such establishments were so popular that they eclipsed the tea and coffee houses.

All this time, chocolate was consumed only in the form of a drink. Only in the 19th century did the Swiss learn how to extract cocoa butter and cocoa powder from cocoa beans. In 1819, the world's first chocolate bar was created, which marked the beginning of a new era in the history of chocolate. Manufacturers around the world began experimenting with the new product, adding nuts, honey, candied fruits, alcohol, and most importantly, milk, which led to the appearance of milk chocolate, which is so beloved all over the world.

At the beginning of the 20th century, chocolate becomes available. During the war, the American and European governments include chocolate in the diet of soldiers. It is thanks to the soldiers who treated the local population with chocolate rations that in the post-war period it becomes popular in Africa and Asia.

How chocolate is made

And how is it done? A lot of things have to happen to cocoa beans before they turn into chocolate bars adored by everyone. First of all, in order to make their aroma even more unusual, and the scales to fall behind more easily, they are fried. When they are fried, an alarm bell sounds. What's next? Further, a wide, similar to a huge chest of drawers, crushing and screening machine ruthlessly crushes, grinds the beans, turning them into grits. From the sorting machine, the grit enters the mill. But what is it? Why does not flour pour out of the mill, but dough creeps? After all, the grain was dry! It turns out that the dough was made from ground cocoa beans because oil was squeezed out of them. After all, the seeds of all plants contain oil.

After that, the hour comes, you need to add right amount sugar, cocoa butter, milk or any other drug. Well, the chocolate is almost ready. He just had to survive. They don’t do anything with the chocolate mass, it calmly stands in the finishing machine, and it will stand like that for three days. And all this time it should be very warm, even hot, fifty degrees. And only on the third day, chocolate will become the way we love it - tasty, fragrant, and it can be stored for a long time.

Today, for people all over the world, chocolate remains one of the favorite treats. With nuts or fruit, bitter or milky, in bars or bars - modern chocolate can satisfy the tastes of the most discerning gourmets.

Analytical stage

Chocolate and health

We once heard from Pope Victoria that pilots and astronauts are given chocolate. We were wondering how it benefits them?

The benefits of chocolate

According to scientists, chocolate can be quite good for health

    Chocolate gives energy, has a stimulating effect, is good for the heart and blood vessels, it is a stimulant of brain activity, a strong antidepressant, very effective remedy from cough, mastered by cosmetology.

    Cocoa powder prevents the destruction of tooth enamel.

    The antioxidants contained in cocoa beans, and therefore in chocolate, help maintain the health of the heart and blood vessels. Dark chocolate contains more antioxidants than milk chocolate.

    Chocolate contains substances called flavonoids. By preventing the formation of blood clots, they improve blood circulation.

    Studies have shown that chocolate lovers are less likely to suffer from diseases such as stomach ulcers, hay fever, and also have a generally higher immunity.

    A series of experiments led scientists to conclude that moderate consumption of chocolate can extend a person's life by a year.

    Chocolate stimulates the release of so-called happiness hormones - endorphins. By acting on the pleasure center, they improve mood.

    Chocolate is useful for children, as well as for those who are actively involved in sports, mental work, are in a stressful situation or have lost a lot of blood.

    Chocolate contains a substance that inhibits the action of bacteria that form tartar.

    Providing an invigorating effect, chocolate contains less caffeine than coffee.

    In addition to cocoa beans, chocolate contains protein, calcium, magnesium, iron, as well as vitamins A, B and E.

    Chocolate is very high in calories, but most of its calorie content is represented by “useful” cholesterol, which preserves vascular health.

Negative influence

Some problems can arise from excessive consumption of chocolate: tooth decay, allergies, overweight, cholesterol. But bars like "Snickers" and "Mars", so loved by all children, are not at all useful. After all, they contain a large amount of sugar and various chemical additives, due to which it is provided highest calorie content.

Conclusion

We believe that in the course of working on the project, all the tasks assigned to us were solved: - we learned about the process of making chocolate;

Find out what types of chocolate are;

Revealed the beneficial and harmful properties of chocolate;

We learned a lot of interesting things about chocolate;

While working on the project, we learned how to extract information not only from books, but also from the Internet, to choose the most important and interesting from it, to draw up information according to a plan. We often argued. We had work to finish, so we learned how to do it together.

Is chocolate good or bad? There are weighty arguments for both supporters and opponents of chocolate consumption - this has also been shown by our research.

The hypothesis put forward was confirmed that chocolate has a beneficial effect on the human body.

The use of chocolate depends on individual tolerance and characteristics of the body.

Interview: "The benefits and harms of chocolate"

Chocolate is the most popular treat for children. In order to determine the effect of chocolate on human health, we interviewed the paramedic of our school, Fedorova Tamara Nikitovna.

Question: Tamara Nikitovna, please tell me, is chocolate harmful or beneficial for the body and how much of it can be eaten without harm to health?

Answer: In fact, chocolate is very useful, if you know the measure. And if you eat it no more than 25 g per day, then it will bring you nothing but pleasure, because chocolate helps to develop “happiness hormones” that appear during joyful experiences, and even the smell of chocolate improves mood and causes positive emotions.

Q: What are the health benefits of chocolate?

Answer: Chocolate is not only a delicacy, but also a wonderful healer. In epidemics of influenza and SARS, you can lubricate the nasal mucosa with cocoa butter, which will protect against infection. With a strong cough, it is better to suck on a couple of slices of chocolate than to drink pills. For bronchitis, as an expectorant, take half a teaspoon of cocoa butter to 1 cup of hot milk. Chocolate contains iron, which increases blood hemoglobin if you are anemic. And when you need to quickly restore strength, then chocolate will help this, because it contains carbohydrates.

Question: Do you think chocolate spoils teeth?

Answer: For a long time It was believed that chocolate destroys tooth enamel, but this is not so. Scientists have found that cocoa beans contain antibacterial components that prevent the occurrence of caries. Japanese doctors suggest adding an extract made from cocoa bean shells to toothpaste, but you still need to brush your teeth after eating sweets.

Question: Can all people consume chocolate without harm to health?

Answer: Overweight people with a disease diabetes, as well as children under 2 years old, chocolate is contraindicated!

Question: What advice can you give to children?

Answer: Eat chocolate in moderation and High Quality, because it is not only tasty, but also healthy.

The assumption that chocolate does more good than harm has been confirmed.

For medicinal purposes, experts recommend high-quality varieties of dark chocolate. This is confirmed by the studies of American scientists. They showed that people who eat chocolate 2-3 times a month feel better than those who completely give up chocolate. The reason for this is the antioxidants found in chocolate.

And with our research work, we answered the question: “Is chocolate good or bad? ".

“Yes, useful! »

Guys, do you have a test tomorrow?

Eat a piece of chocolate so that you have the mind and strength to work!

Relevance

Chocolate is a favorite treat for children.

Modern children get the opportunity to consume various types of chocolate products. Adults are worried, but is it harmful?

Story

The word "chocolate" comes from "chocolatl", the name of a drink made from cocoa beans. In the Aztec language, "chocolli" means "bitterness" and "atl" refers to the water used to make a chocolate drink.

The word "cocoa" has been used since 400 BC. before 100 AD Maya Indians (they are also called Yucatecs) are representatives of one of the most mysterious world civilizations that flourished in southeastern Mexico, Honduras and Guatemala.

Christopher Columbus was the first European to taste chocolate.

How chocolate is made

Chocolate is different confectionery made using cocoa fruits. Cocoa fruits are the seeds of the cocoa tree, or chocolate tree. This tree grows in hot tropical countries of the globe.

Harvest cocoa 2 times a year. It takes a lot of effort to collect everything. ripe fruit. Cocoa beans are inside, in the white pulp of the fruit, 30-50 pieces each. They have a bitter taste and a pale color.

Dried cocoa beans are roasted, they acquire flavor and aroma. They are crushed, ground into powder and oil is squeezed out of them. The pressed oil will be used to make chocolate bars. And what is left (cake) is crushed at the factory into a fine brown powder called "cocoa".

That's what chocolate does. Milk or cream is poured into cocoa butter, cocoa powder, sugar, vanilla, nuts, raisins (depending on the type of chocolate) are poured and everything is mixed.

The dough is poured into molds and cooled, so appetizing-smelling tiles are obtained.

Chocolate composition

Chocolate contains vitamins A, B1, B2, iron, phosphorus, potassium, proteins, fat, carbohydrates, caffeine.

Health impact

Caffeine is a psychostimulant. Even in moderate doses, it increases mental performance, improves mood, creates a feeling of cheerfulness and a surge of strength. Stimulates cardiac activity, dilates the vessels of the heart and kidneys.

Chocolate contains substances that affect the emotional centers of the brain and create a feeling of well-being in the human body.

Biologically active substances reduce and regulate the mechanisms of origin of pain, depression, memory, appetite. They improve sleep processes, thereby acting on the body as an antidepressant.

Many people believe that it is the consumption of chocolate that leads to overweight and obesity. The same can be said about the huge number high-calorie foods and drinks. For example, calorie content of 100 g roasted sunflower seeds almost the same as 100 g of chocolate bar. Naturally, people who are prone to fullness should avoid eating any sweets.

Researchers at Harvard University conducted experiments and found that if you eat chocolate three times a month, you will live almost a year longer than those who deny themselves such pleasure.

But not everything is rosy here either. The same study shows that people who eat too much chocolate live shorter lives. Chocolate contains a high percentage of fat, which means that excessive consumption can lead to obesity, and thus an increased risk of heart disease.

CONCLUSION

Chocolate is the most natural product so it can't be harmful. It seems that the old adage "everything is good in moderation" applies here as well. Therefore, by eating 2-3 small pieces a day, you can maintain a good memory, mental clarity and a good figure.
