Classification esaay: How many kinds of food?

Food is one of the basic needs of the human being. It is required for the normal function of the body parts and healthy growth. Every day, we eat a large variety of foods. These foods are classified into three different groups according to their composition; they are vegetarian food, non-vegetarian food and synthetic food.

The first group, the food we get from the plant source is considered as a vegetarian food. We have a variety of vegetables such as tomato, potato, carrot, spinach, etc; and fruits like: mango, apple, orange, grapes, and lemon…Vegetarian foods provide several vitamins, minerals, fibers and enzymes. Green, leafy vegetables are rich in iron, which is an important constituent of blood. Because vegetables are low in sugar and fat, they are useful for people who are on diet. In addition, vegetables contain high amount of fibers, so they are good for the digestive system. Fruits are rich in source of carbohydrates and they contain high quantity of antioxidants; therefore, they protect the body from harmful substances. People said that if we eat a lot of vegetarian food we will have a fair, smooth and shiny skin. We should eat enough vegetarian foods that 600g vegetables and 400g fruits to supplement vitamins, minerals, fibers and enzymes for our bodies.

The second group, the non-vegetarian foods obtained from the animal source. This group includes eggs, meat and fish. They are the most important source of proteins, zinc, iron and B vitamins. These nutrients are necessary for growth and repair of the body. In fact, eggs are rich in iron and protein; meat is major source of vitamin B12; fish is also a significant source of proteins. We should eat 4 eggs, 500g meat and 700g fish per week to balance our diet and ensure our health. If we follow this regimen that means we eat enough non-vegetarian foods each day, we will have strong and firm muscle; we also can resist diseases. E synthetic food

If vegetarian and non-vegetarian foods provide us with a lot of nutrients, the last group is the synthetic food which contains fewer nutrients but it helps us avoid hungering in a while. The synthetic foods are made by human being; they use available materials and create new things. We have some examples of synthetic foods: ice-creams, syrups, jellies, candies, pharmaceutical tablets and so on…This kind of food contain much sugar, fat and chemicals. It is not good if we eat synthetic food every day because the amounts of chemicals are harmful for our health. The synthetic foods just have effect in a while. For example, in a hot afternoon, if we eat an ice-cream, it will make us relax and reduce hot. On the other hand, if we eat 5 ice-creams at the same time, after that we will be throaty due to the chemicals in these ice-creams. The synthetic foods just have temporary benefit, so we should notice about the usage of synthetic food to avoid harmfulness.

Food is the only source to obtain nutrients in an adequate quantity. If we do not get these nutrients in sufficient amount, then we may suffer from a number of health problems. We should balance these three groups of foods: vegetarian food, non-vegetarian foods and synthetic foods in our daily diet so that we can maintain the normal functioning of the body and lead a healthy life.

Argumentative essay: Copyright laws should be applied all over the world.

Copyright is a form of protection provided by the laws of the government to the authors of “original works of authorship,” including literary, dramatic, musical, artistic, and certain other intellectual works. Therefore, to ensure the originality and the interest of the authors we should apply copyright law all over the world.

Copyright laws prevent people from using protected materials without the authors’ permission. Today, there are many bad people who want to steal original works of others, edit and make them become their own property. It is a form of copyright stealing that will damage the heartfelt enthusiast of the authors. When copyright laws are applied, if anyone steals copyright, they will be fined according to laws. Copyright laws protect authors’ right, encourage and inspire them to create without worrying about being stolen; day by day, there are many masterpieces all over the world.

When copyright laws are applied the owner can also benefit from these laws by selling or agreeing a transfer of copyright to others. According to government, copyright is a form of Intellectual property. Therefore, it is like any form of property; it can be bought, sold, transferred, and inherited and so on. For example, Trade Mark composed the song “Only love” and he bought copyright for his work; if anyone buys this song Mark can sell with high price because his song is unique and he can earn a lot of money. Copyright laws give the authors, the creators many opportunities to get profit, fame and wealth; these will encourage everyone to try their best and create to contribute to life.

The poor will have to face with many difficulties because of copyright laws; they cannot afford to buy expensive works, they have fewer changes to enjoy knowledge of human being. However, without copyright laws, the evil purposes will appear and cause unexpected problems to the authors. For instance, Mr. A create “Tea for reducing weight”; Mr. B hate Mr. A, he wants to make harmful things for Mr. A, he can buy this product, ad some poisonous chemicals, deliver to market field of vision . As a result, the customers are poisonous, they rumor and warn others, people will not buy this products and the company of Mr. A is ruined. Copyright laws provide the authors, the creators with the right to sue if someone damages or derogatory the works; it also gives safety for Intellectual property. The government can help the poor by buying copyright for them.

Copyright laws are new laws that protect the authors and the creators; ensure equality in our life, avoid evil purposes. Our world will become civilization, human being will more intelligent and creative owning to copyright laws.
