History reference

Crisps - This is a light snack made from potatoes.

The history of their appearance is connected with 1853, when millionaire Cornelius Vanderbilt returned the fried potatoes to the cook, complaining that they were “too fat” and several times asked to cut the potatoes thinner than usual. In the end, the cook got angry, took a sharp razor and made the slices a little thicker than a paper sheet. After frying them in boiling oil, he served this original dish to the guests. Everyone was delighted.

Cornelius Vanderbilt

Soon, crispy potatoes, as a new invention, were patented, and its inventor, chef George Crum (an Indian by origin), founded a potato chip company. Their production is widely developed in the West. There their name appeared, derived from the English word "chips", which means "slice, piece."

George Crum

At first, chips were sold only in expensive restaurants.

Later, crispy potatoes began to appear in

ordinary canteens.

Especially crispy potatoes came

to the taste of the kids

And today, nutritionists have added chips to the banned list.

for kids food

Sociological survey

Using the survey method, we decided to find out how often schoolchildren eat chips.

To begin with, we identified the target audience, these are children from 7 to 16 years old, then made up questions.

The form consisted of 6 questions with suggested answers.

The survey involved students in grades 1-11, the total number of participants was 134 people.

Here are the results we got:

1. How often do you eat chips?

2. Do you like chips?

a) often - 14

b) rarely - 6

a) yes - 14

3. If you like it, then why?

b) no - 5

a) delicious - 11

4. Do you think chips are bad?

c) don't eat - 4

b) beautiful packaging - 4

a) yes - 10

5. Do you pay attention to the composition of chips?

b) no - 14

a) yes - 9

6. Do your parents let you eat chips?

c) alluring smell - 7

b) no - 12

a) yes - 8

b) no - 11

c) they don't know about it - 5

Chip makers are doing everything they can to make sure we can't stop eating crunchy snacks. Chips are loved by both adults and children.

But, in fact, their packs should have health warnings, like cigarettes and alcohol.

We carefully read the composition of the chips on the package and found that

what they include:

• potato
• vegetable oil
• salt
• lactose
• E 621 (sodium glutamate)
• E 330 (citric acid)
• natural and naturally identical flavors
• sodium phosphate
• acrylamide

Harmful food additives

The composition of the chips includes various food additives:

flavors, dyes.

Food supplements serve to staining, giving taste.

In the chips we are considering, we found such harmful additives as:

Monosodium Glutamate - MSG (Monosodium Glutamate) food additive - E621

Turn the most tasteless food into one

which you want, eat again and again.

Negatively affects the brain.

Causes addiction and addiction, allergies, asthma, kidney failure, disrupts the structure of the retina, digestive problems.

RETINAL DETACHMENT

calcium phosphate - food additive E 341.

Causes stomach upset in children.

sodium phosphate

threatens the development of osteoporosis and slowing of bone growth in children.

Malic (malonic) acid strictly prohibited

in baby food.

Sodium inosiate - food additive E631.

When eating an additive taste and smell enhancer, you need to be especially careful and careful for allergy sufferers, asthmatics, since sodium inosiate can provoke an exacerbation of diseases.

All chips contain salt

But a specific amount of salt

not specified.

Excess salt slows down the growth of children's bones, and children run the risk of remaining the last and lowest in the ranks in physical education.

Salt retains water in the body, which increases blood pressure.

They weakened, began to make mistakes in the passage of familiar labyrinths and began to get tired much faster.

As a result, ten days was enough for the animals to become less attentive, unable to quickly concentrate, and poorly coped with ordinary tasks.

In the process of frying, absolutely everything useful that is in the potato is destroyed, it acquires other properties - carcinogenic.

The breakdown product of fats acrolein , has mutagenic and carcinogenic properties.

To avoid the formation of a large amount of acrolein, frying oil should be changed regularly.

Acrylamide- an even more dangerous carcinogen, also formed even at home, if you choose the wrong oil and heat the pan too hot. What can we say about the conditions of in-line production, when many batches of chips are cooked for a long time in the same overcooked fats, which are often unprofitable to change?

And besides these already found substances, how many other toxins formed during the preparation of chips have simply not been studied?

Studying the nutritional value of chips

In order to find out what the chips are in terms of nutritional value, we studied the indicators from a package of an average pack of chips weighing 100 g and compared them with the daily allowance for children.

Here's what happened:

In 100 grams of product

In a bag of chips

Fats

Squirrels

Daily rate

for children 7 - 15 l

Carbohydrates

Salt

calories

2350 kcal

550 kcal

We found out that chips contain a lot of fat. This is a very high calorie product. Salt in a pack contains half of the daily requirement.

That's a lot!

Holding

experiments

EXPERIENCE #1

Knead the chips inside

clean wipes

A large greasy spot was seen at the place of pressure, which confirmed that Chips are high in fat.

EXPERIENCE #2

Dropped on chips

iodine solution

After a few seconds, a dark blue spot appeared.

This indicates the presence of starch, the remains of which in the mouth are converted into glucose within two hours - an ideal nutrient medium for caries bacteria.

When accumulated in the liver, glucose leads to obesity.

Chips are bad for your teeth and liver!

EXPERIENCE #3

When lighting a slice of chips, we noted the appearance of a pungent smell of plastic, which indicates the presence dangerous carcinogen - acrylamide , which is considered a poison for our body, causes diseases of the nervous system, liver and kidneys.

In plastic, its smell is pronounced, but in chips it is not felt, because they contain artificial aromatic substances.

Acrylamide is a cancer-causing substance that affects the nervous system. In some types of chips, the level of this deadly substance is exceeded in ... 1280 times!

NO GRAM OF USE!

There is not an ounce of benefit in the product - no vitamins, no minerals, no nutrients that could strengthen the growing body.

After processing, the potato loses all its useful properties and acquires harmful ones.

Vitamins and minerals

no chips!

Ministry of Health care banned sell chips and other similar products in school canteens and cafes.

Doctors explain their decision by the fact that the number of children with digestive diseases has increased by one and a half times in recent years.

And it's all because of unhealthy food.

Children's diseases associated

with malnutrition

Gastritis – a common disease of the digestive system today. In scientific language, gastritis is an inflammation of the gastric mucosa, leading to dysfunction of the whole body, especially the functions of the nervous system.

General signs of gastritis: heaviness and pain in the epigastric region, poor appetite, nausea, vomiting, heartburn, coated tongue and poor condition.

• deterioration of the pancreas, kidneys, liver;
• decrease in immunity;
• increased risk of developing cardiovascular disease;
• obesity
• contributes to the development of cancer

Our findings

Through research, we found that:

1. Crisps - This is a fatty fried food that contains harmful food additives.

2. All chips are very salty, and excess sodium chloride interferes with normal bone growth, disrupts metabolism and causes heart problems.

Our findings

3. This product is rich in dyes and flavors - they help to make potatoes with the taste of red caviar, salmon, shrimp or sour cream with dill.

4. Used additives can cause allergies in a child, and their accumulation in the body can lead to more serious consequences (they were invented recently, so their effect has not been fully investigated).

Our findings

5. The abuse of such food adversely affects the work of many human organs.

So, the chips do more harm than good.

Working on this topic, we came to the conclusion that

that chips are a harmful product and cause various diseases. So they do more harm than good.

The topic of the work is revealed, the problems are solved, and the hypothesis is proved.

The work done not only enriched us with new knowledge and skills, but was also very interesting, requiring independence and a creative approach.

In general, we sincerely wish you to remember how many truly tasty, healthy and healthy dishes there are in our native Russian cuisine, and then you and your children simply will not know what chips are.

To be always healthy

Vigorous, slender and cheerful,

We are ready to advise you

How to live without doctors.

Gotta eat tomatoes

Fruits, vegetables, lemons.

Porridge - in the morning, soup - in the afternoon,

And for dinner - vinaigrette!

If you don't eat chips

And you will forget about them

That, of course, there is no doubt

Live for many years!

INTRODUCTION

Chips are considered one of the most popular products among young people, while they consistently rank at the top of the list of unhealthy products. At first glance, it seems that chips cannot contain anything harmful to the body, because in fact it is the same product as boiled potatoes, which are cooked almost every day in many families. However, everything is not so simple!

The harm of chips outweighs the dubious benefits of this product. According to studies, even a healthy person after daily consumption of a pack of chips a day for a month begins to suffer from heartburn, gastritis and intestinal diseases. And prolonged consumption of a dangerous product can lead to more serious health problems.

Due to the fact that the amount of dangerous carcinogens in chips is 500 times higher than normal, cancerous tumors can occur. In addition, there is a lot of salt in the chips, which cannot but affect the metabolism.

Chips are especially harmful to children - they contain all kinds of additives that are used to prepare the product, they can provoke severe allergies. Eating chips leads to overweight. So, before you eat a pack of oily cereal, think about your health and choose something more healthy for the body.

PURPOSE: Based on my research work, I want to prove that eating chips causes great harm to health.

OBJECTIVES: 1. Learn the history of chips and the technology of their preparation

2. Find out why they are harmful.

3. Prove empirically, the presence of harmful additives in the product.

4. Conduct a survey of classmates on the topic "Healthy Eating".

5. Based on the results of the work, draw conclusions about the dangers of chips.

THEORETICAL PART

The history of chips

The name "chips" comes from the English "chips", which means "piece", "slice". The history of the creation of chips begins in 1853, and they appeared quite by accident. Once Cornelius Vanderbilt, a millionaire from America, stayed at the Moon Lake House Hotel, which is located in Saratoga Springs. While dining at the hotel, Vanderbilt expressed his displeasure three times over the fact that the potatoes were cut too large slices. Local chef George Crum, being a man of character, ended up cooking thinly sliced ​​potatoes fried in oil for the millionaire. Unexpectedly, the chef's new dish was to Vanderbilt's taste. He gladly ordered it every time he dined at the hotel. Thus, "Saratoga chips", as they were nicknamed, became the restaurant's signature dish.

Seven years after the incident, in 1860, George Crum opened his own restaurant serving chips. However, over time, this dish has appeared in other places of food, which is not surprising, since it is not difficult to make chips. Soon the chips appeared on the menu of the best restaurants in America.

After another 36 years, the idea was born to pack chips in wax paper. Laura Scudder said it. Such packaging made it possible to transport the chips and extend their shelf life. Thus, the chips appeared on the shelves of supermarkets. However, the mass production of chips became possible only after the invention of the potato peeling machine. Somewhat later, the first machine for the industrial production of chips appears. Created by Freeman Macbeth. His invention was immediately acquired by one of the firms, which began mass production of chips.

The chips were made without the addition of salt or any seasonings. In 1940, Tayto makes its first flavored chips and sells chips with a packet of salt.

Currently, manufacturers offer a huge selection of chips with different flavors. There are two main ways to produce chips today. The first method involves the production of chips from pieces of raw potatoes (it is called traditional), the second - from chopped potatoes.

WHY YOU SHOULD NOT EAT CHIPS

Boldov Alexander, Ruzhnikov Yuri

The work is devoted to the effect of chips on the human body.

Chips are a very popular product, especially among children. They are eaten while watching cartoons, in nature, and even just out of boredom. They are tasty and crispy.

How do they affect our body? After conducting experiments, we found out that chips are harmful.

In this work, the following methods were used: experiment, observation, generalization, information processing, study of popular science literature on the topic.

TOPIC: Chips. Harm or benefit? The work was also carried out by: Alexander Boldov, Yury Ruzhnikov

Purpose: To reveal the effect of chips on the human body

Hypothesis. We assume that chips are a useful product.

Tasks: 1. Learn information about chips. 2. Conduct experiments that will help determine the effect of chips on the human body. 3. Make recommendations about chips for classmates.

Research methods: 1. Analysis of scientific literature. 2. Experiment. 3. Observation. 4. Studying the results of activities.

Scientific article What are chips? Chips (English chips, from chip - chips) - a snack, which is thin slices of potatoes, less often - other root crops, usually fried in oil (deep-fried). Sold as a ready-to-eat food product.

In 1929, the first machine for the industrial production of chips was invented. It was invented by self-taught mechanic Freeman Macbeth, who sold the car to one of the firms.

EXPERIMENT 1 Take a slice of chips, put it on a napkin and carefully fold it in half, crushing the test sample on the fold of the paper. We remove the pieces of chips from the napkin.

Observations showed: A large greasy spot formed on the napkin. The more fat the product contains, the larger the size of the light-transmitting spot.

Conclusion: Chips contain a large amount of fat. This experience disproved the hypothesis about the benefits of the product. Chips are very fatty. In 100 g, it contains fats in such quantities that for a child it is half the daily food intake. And this contributes to obesity.

Experience 2. Let's take a 3% solution of iodine and drop it on the chips. Observations have shown: After a few seconds, a dark blue spot appears, which betrays the presence of starch.

Conclusion: Chips contain a lot of starch. This experience also refuted the hypothesis about the benefits of chips. According to a US study, the starch left in the mouth is converted into glucose within two hours. And this is an ideal breeding ground for caries bacteria.

EXPERIMENT 3 We take a slice of chips and carefully set it on fire, observing all fire safety measures.

Observations showed: When a slice of chips is set on fire, a pungent smell of plastic appears (photo 3). This indicates the presence of a dangerous carcinogen - acrylamide.

Conclusion: The chips contain a dangerous carcinogen - acrylamide. This experience also did not confirm the hypothesis about the benefits of chips. They contain a carcinogen - acrylamide, which is considered a poison for our body, affecting mainly the nervous system, liver and kidneys. In plastic, its smell is pronounced, and in chips it is veiled with the help of flavors.

Conclusions: Due to the high content of carbohydrates (starch) and fat, chips are very high in calories. The fats contained in chips are extremely hazardous to health, as they have a carcinogenic effect, that is, the ability to cause cancer. The chips contain a carcinogen - acrylamide, which is considered a poison for our body, affecting mainly the nervous system, liver and kidneys.

Thank you for your attention! Eat Healthy Foods! Good health to you!

DESCRIPTION OF THE RESEARCH PROGRESS

2.1 History of chips

The word "chips" came to us from the English language, meaning "shavings". It is believed that the chips were accidentally inventedGeorge Crum , Indian by origin.24 August 1853 , at the resort Saratoga Springs (USA ), while working as the chef at the fashionable restaurant at the Moon Lake Lodge. According to legend, one of the signature recipesrestaurant was " French fries ". One day at dinner, a railroad tycoonVanderbilt returned the fried potatoes to the kitchen, complaining that they were "too fat". The chef, Krum, decided to play a trick on the tycoon, cut the potatoes literally paper-thick and fried. But the magnate and his friends liked the dish.

2.2 The opinion of experts on the effect of this product on the human body.

What do the experts think? I studied the opinion of experts on the effect of this product on the human body. It turned out that the chips take first place in the list of the most harmful products. Chips are nothing more than a mixture of carbohydrates and fat with the addition of salt, dyes and substitutes for different flavors. Especially harmful are chips made not from whole potatoes, but from potato flour.
And although the potato itself is a useful product, it contains almost all chemical elements, in the process of powerful processing, which the potato undergoes in the production of chips, it loses all its useful properties, and instead acquires harmful ones. Due to the high content of carbohydrates (starch) and fat, chips are very high in calories. 100 g of chips contains 510 kilocalories, which is almost a third of the daily allowance for a child. That's why chips contribute to obesity.
Chips are very salty, and excess salt interferes with normal bone growth, disrupts metabolism, and can cause swelling and heart problems. The fact is that the main component of salt - sodium - has the ability to retain water: one of its molecule is surrounded by 400 water molecules! The heart has to pump more fluid through the vessels than usual, the pressure in a person rises.
Colors and flavors that give chips a ham, dill sour cream, or shrimp flavor can cause allergies. And the fats contained in chips are extremely dangerous to health, as they have a carcinogenic effect, that is, the ability to cause cancer. The fats contained in chips are the so-called hydrogenated fats. An example of such a fat is margarine. Such fats increase the level of cholesterol in the blood and increase the risk of atherosclerosis, heart attack and stroke, even at a young age, although previously these diseases were considered exclusively age-related.
There are no vitamins and minerals, not to mention the useful fiber found in apples, carrots and other vegetables and fruits, in chips. And at the same time, as scientists have found out, chips can be addictive! That is why, once having tasted thin slices of fried potatoes, the kids crave to crunch them again and again. . The average pack of chips weighs 90 g, the energy value of such a quantity of chips is about 500 kcal, and it is achieved due to technical fat, which is literally soaked in potato slices. In many products that have undergone heat treatment over 120 degrees, scientists have found huge concentrations of acrylamide, a substance whose toxic effect can cause cancer. According to European standards, the content of acrylamide should not exceed 0.1 micrograms per kilogram. And in a kilogram of chips, 1000 micrograms of this substance were found. Acrylamide is formed during the preparation of deep-fried or grilled foods, and practically not during cooking. .
Conclusion: thus, for the most part, nutritionists agree that chips do not benefit the body, they have a high calorie content.

2.3 How to make chips

Chips are prepared in two ways: molded and traditional. In the traditional way, the product is prepared from thinly sliced ​​potatoes, fried in oil, salted and flavored. Molded chips are made from potato granules or flakes that are soaked into dough, rolled and fried, seasoned. Chips are fried not in healthy vegetable oil, but in technical fat. .The manufacturer often uses palm oil for frying. Palm oil is a vegetable oil obtained from the pulp of the fruit of the oil palm. The seed oil is called palm kernel oil. The main reason for the widespread use of this oil is its low price. In most developed countries, the import of palm oil is limited, due to its high carcinogenic effect. Benefits: When palm oil is added, the shelf life is extended, as it does not go rancid, it is resistant to heat, therefore it is used in deep frying. Palm oil is rich in vitamin E and provitamin A, which are powerful antioxidants, widely used in cosmetology. The liquid part of palm oil is called palm olein. Palm olein is a light yellow liquid that does not require additional processing, which makes it an excellent substitute for vegetable and soybean oils; its use in production allows:

1. Exclude soot.
2. Reduce oil consumption when frying.
3. No foreign taste.
4. Uniform bright golden color of products.
5. Easily mixes with other oils. .

Conclusion : Manufacturers use technical oils that have a high carcinogenic property, which contributes to the development of cancer. More often, instead of potatoes, potato or corn starch is used, which increases the calorie content of the chips. In addition, even if the manufacturer uses potatoes, this product loses its beneficial properties during powerful processing.

2.4 Practical part
2.4.1 Survey results

I conducted a survey among the students of our class. (Table 1) The survey involved 25 people. It turned out that my classmates know about the dangers of chips, but, nevertheless, they use them with pleasure. 9 of the respondents buy chips 3-4 times a week. 13 people - rarely (about 1-2 times a month). My classmates prefer such brands as Lace (14 people), Pringles (6 people), Bingre (2 people).

2.4.2 Comparative analysis of chips
I studied the rating of consumer preference in terms of choosing a brand of chips. And for my research I chose three brands of the most popular companies, these are Lace, Estrella, Pringles. And three brands that occupy low positions in the ranking: Pro, Mini Free, Bingre. On the Internet, I watched a video test, where an experiment was conducted to determine the fat content, and therefore acrylamide, in various brands of chips. I decided to do the same experience at home,to do this, put a large chip on paper, bending it in half on both sides. Remove the rest of the chips and look at the paper on it there will be a greasy stain. The more fat, the larger and clearer the stain. A bright color indicates the presence of dyes in the chips. (table 2).
Conclusion: All tested chips contain fat. Moreover, Lays, Pro, Mini Free chips have the largest amount of fat. We also see the presence of the dye. Leis and Mini Free came out on top.Dyes can cause allergic reactions in some people. Especially this problem concerns children with not yet strong organism.
I also studied the composition of these brands and entered the results in a table. (table 2).
Conclusion: 1. All tested chips are low in protein. The amount of fat is above the norm, with the exception of Mini Free chips. The amount of carbohydrates is much higher than in Mini Fries and Bingre chips. All chips are high in calories.After eating a 100 gram bag of chips, we will get the same number of calories if we ate 633 grams of boiled potatoes or 80 grams of butter, as well as 100 grams of chocolate (1 bar).
2. One hundred grams of the product contains almost a gram of salt, when the optimal dose for children is 2 grams per day and for an adult 5-6 grams. Excess salt can lead to a slowdown in the normal growth of bones, in addition, disrupts the metabolism in the body.
3. Tested chips contain chemical additives E.This is an abbreviation for "Europe" - Europe, as the European Commission on Food Additives labels chemical compounds contained in products, followed by a three or four-digit number, in which the full name of the compound is encoded. .

E 47 - stabilizer, emulsifier - improves the appearance and texture of the product.

E 621 - monosodium glutamate, used to enhance and preserve taste. This substance cannot be called harmful. And it needs the heart muscle and the brain. With a shortage, the body can synthesize it itself, and with an overabundance, it has a toxic effect, primarily on the liver and pancreas.

E627 disodium guanylate - flavor enhancer, can cause indigestion, allergic reactions.

E631 sodium inosinate - flavor enhancer

E160 lycopene dye, colors in a palette of red colors, is not dangerous.

E635 sodium ribonucleotide - a flavor enhancer - is able to enhance the taste and aroma lost during heat treatment, and can cause indigestion. Not recommended for children, pregnant and lactating women.

E551-silicon dioxide - natural material (quartz, sand) is used foravoid clumping, caking.
The most dangerous: E - 627, 621, 635.

CONCLUSION

Thus, my research has proven that chips have a negative impact on human health, especially on the children's body.
1. In fact, chips do not contain any useful substances, vitamins, minerals, good carbohydrates and proteins. The main component of salt is sodium, and it is he who retains water in the body.
2. The high content of fat and starch makes chips a high-calorie food that can lead to obesity if consumed uncontrolled. Also, fats can cause a heart attack or stroke in a person even at an early age, although not so long ago these diseases were considered age-related.
3. Do not think that chips are fried potatoes. After such processing, all useful substances disappear from the potato and harmful substances remain. So do not believe flashy advertisements, since chips are unlikely to benefit the body.
The value of this work is that my classmates and I reconsidered our attitude to chips. I think my work may well come in handy, in the lessons of the world around us in elementary school and in extracurricular activities. After all, our health is priceless and we need to take care of it already in childhood.

Purpose: Find out if chips are really a harmful product. Research objectives: - to find out the history of the appearance of chips; - consider the qualitative composition of the chips; - to study the effect of the product on human health; - experiment with chips; - to analyze the obtained results.

The history of chips. Chips were accidentally invented by George Crum on August 24, 1853, while working as a restaurant chef. According to legend, one of the restaurant's signature recipes was French fries. At dinner one day, a very wealthy gentleman returned the fried potatoes to the kitchen, complaining that they were "too fat." The chef, who decided to play a trick on the tycoon, cut the potatoes literally paper-thin and fried them. The dish was liked by the magnate and his friends. This recipe soon became very popular. Currently, $2 billion worth of chips are sold annually in the world, and 10 million kg of chips are sold annually in Russia. Based on these figures, we can say that chips are a favorite product. What is its use? But before answering this question, let's look at the technology of cooking.

Holds multiple bags of chips.

The composition of chips. Ingredients: potato, vegetable oil, whey powder, wheat flour, lactose (from milk), flavor and aroma enhancer (monosodium glutamate, sodium 5 ribonucleotide), hydrogenated vegetable oil (including soybean), glucose, natural, identical to natural and artificial flavors, acidity regulator (citric acid), cheese powder, color (paprika extract, turmeric extract), garlic powder, milk protein, maltodextrin, salt. Here I found such harmful additives: 1. Monosodium glutamate (sodium glutamate) - additive E621. I draw your attention to the fact that on the packages of the chips I studied, it is not written anywhere that this is a food supplement. This additive has toxic properties and can be food addictive and addictive. People have health problems - allergies, bronchial asthma, kidney failure, the structure of the retina is disturbed, the hormonal balance in the body, digestive problems, gastritis and stomach ulcers can develop. 2. Calcium phosphate - additive E 341, also not marked as a food additive E.
