Firstly, food plays physiological role in the lives of people. Food provides the development and updating of the cells of the organisms. It is the source of energy for our vital activity - height, weight, normal hematopoiesis, vision, skin, performance and longevity. Also, food has an effect on the mental development of the organism. For example, there are products like alcohol, sweets, fast food, red meat, fat food that can cause depression. Not tasty and monotonous food can contribute to nervous diseases and mental disorders, as tasteless food reduces the emotionality, causes the apathy and promotes the fatigue. On the other hand, people eat vegetables, fruits, and fish less likely to suffer from the depression. There are necessary nutrition for human lives - water, carbohydrates, proteins, fats, minerals, and vitamins. They protect our organisms and vital organs, regulate systems, build genetic material and help to keep our skin, organs and hair in good shape. We get them by food that we eat.
Secondly, the social role of food in our lives is important, too. Food helps us to communicate with the family members, friends, colleagues and partners. There are the good traditions to meet with the family and friends to celebrate the holidays or the memorials at the same table. Family meals, where family members can discuss the current occasions and events of their lives, or to discuss plans for the future are very important for all generations. It helps the family members to get close, and friends to meet again in our busy time. A good opportunity to get close to the colleagues is a meeting with them in informal conditions at the holiday table. The discussions of the important issues with business partners are also not complete without a cup of coffee, lunch or dinner in the restaurant, which dispose to make the right decisions in business. Now we have a great opportunity to get acquainted with the cuisine of the other nations. People can do it by visiting the national restaurants. They can learn about cooking of the certain dishes from their foreign friends and acquaintances. With new dishes, we can increase our rations and enter the new dishes and food. And also we can introduce the cuisine of our own country to people from the different cultures. This is one of the ways to explore cultures of the other countries which is very important for understanding people of different cultures.
In conclusion I would like to remind that nutrition plays very important social and physiological roles in human lives, so it should be: balanced in the quality and quantity compositions, regular - 4-5 times a day in small portions, sterling with a ratio of the proteins, fats and carbohydrates 1:1:4 in the day, variety - vegetables, meat, fish, nuts, berries and herbs. This will contribute to the maintenance of health, physical and mental health and active longevity
