FoodЕдаFood is an essential part of our daily life. One famous English saying goes “We are what we eat”, and it’s true. The food we eat can influence our body and our mind. It contains nutrients, such as proteins, vitamins, minerals, fats, carbohydrates. Different products contain different nutrients. For example, we can get lots of vitamins eating fruit and vegetables. As for me, I like salads very much but I don’t like meat products. The food we choose to eat depends on many factors. First and the most important is the taste. If we like the taste of the product, we often eat it. The second factor is its nutritional value. If the product is healthy and useful for our body, we should add it to our ration. Other factors include culture and religion. Advertising also influences our choices a lot. When we see colourful ads on TV, we decide to try the product. For some people food is just a fuel for energy. For me, it’s a pleasure. I like almost everything, except meat products and spinach. My usual day includes three or four meals. For breakfast, I prefer a cup of tea with a cheese and ham sandwich. Sometimes I eat cereal with milk and drink a glass of orange juice. For lunch, I prefer salads from fresh vegetables and a soup. At about 5pm I have a cup of coffee with shortcake. For dinner, I like pasta or rice with vegetables. Sometimes I eat French fries and hamburgers but I know that it contains a lot of fat. That’s why I try to cut down on fast food. I also try to it less sugar and salt.

Мы - то, что мы едим. Мы должны питаться правильно, не забывать есть фрукты и овощи, поддерживаться режиму, не забывать завтракать, обедать и ужинать, следует пить много воды, тогда наш организм будет очищаться и мы будем чувствовать себя хорошо. Наше тело будет здоровым и красивым. Если мы будем придерживаться этой норме, а так же заниматься спортом, то наш организм будет сильным. Но если мы будем есть много фастфуда и полуфабрикатов, то нам станет хуже, нам будет тяжело двигаться и работать. Надеюсь мы все будем питаться правильно и не забывать об этом.

We're what we're eating. We must eat right, do not forget to eat fruits and vegetables, maintain the regime, do not forget to have breakfast, lunch and dinner, you should drink a lot of water, then our body will be cleaned and we will feel good. Our body will be healthy and beautiful. If we adhere to this norm, as well as exercise, our body will be strong. But if we eat a lot of fast food and semi-finished products, it will become worse, it will be difficult for us to move and work. I hope we all eat right and don't forget it.
