These days we keep looking for the root of our numerous health troubles. Meanwhile, the answer is clear, it is our contemporary ways of life, but we stubbornly refuse to accept this fact. It is important to note that, refusing to see the issue is not the same as solving it. It will not go away! That is why we keep wandering inside the vicious circle of our hackneyed lives, jobs, heavy thoughts and endless health issues until finally we lose the game.

Let us analyze the most dangerous things affecting our health and making our existence unbearable. Specialists from all over the world tend to enumerate the following reasons of our plentiful disasters:

- poor ecology - drinking dead or bottled water, eating fast food, breathing in polluted air;
- living in big crowded cities with constant smog and noise round the clock and no privacy at all to balance our nervous system;
- lack of sound sleep - we choose to entertain or take extra jobs instead of having a refreshing sleep;
- lack of physical exercise - our bodies were created to run, jump, climb, bend and perform hundreds of other motions and with all that we motionlessly sit long hours at our desks in the offices working and in front of TV sets or computers at home having rest. We seldom have a hobby like cycling, horse-riding, swimming, jogging etc.;
- daily stress at work and in our family life;
- forgetting about the necessity of staying in bed when we are unwell, taking pills that hide the symptoms of flue, cold etc.;
- bad nutrition - because we are so busy we have hasty meals. When we in the end make up our mind to have a bite we gobble fast food hardly ever chewing it.

Our ancestors never forgot that we are what we eat and they took greatest care of their meals. As you all know, mankind started as hunter-gatherers about 250,000 years ago. As soon as the tribes and nations became settled many generations of men and women for hundreds of years existed on growing plants and animals and trade. Unlike us, they drank clean water, had natural food, inhaled unpolluted air and had calm lives.

The diet of ancient men and women differed a lot because of climate and season change. Depending on location the food in the tropics was based on plant foods. On the contrary in the northern parts the diet of our ancestors was based on animal products.

Agriculture that appeared about 10 000 years ago in different regions of the world enriched human ration with grains - wheat, rice, maize - and potatoes. What is more, from this time we can speak of the first staples such as bread, pasta and tortillas. At the same time ancient individuals got the diversity of vegetables and fruit as well. Due to farming men and women finally enriched their ration with the availability of meats, milk and dairy products.

Storing food was a type of sacred action - keeping it safe it from infestation and contamination risks was, in fact, a question of survival. The shocking fact is that ancient cooking was a type of ritualistic activity, too. Personalities kept to absolutely strict recipes and procedures thus receiving food of wonderful purity and consistency.

Now you see, mankind has an impressive history of having grains, potatoes, vegetables, fruit, meats, milk and dairy products. That is exactly why your belly feels absolutely comfortable receiving porridge, boiled potatoes, or cooked lean meat - we have a type of genetic ability of digesting it!

Our wise ancestors realized that you cannot survive without good top-quality food. Ancient Greek sage Anaxagoras was the first human to state that food is absorbed by the human body. Anaxagoras was sure the staples contain definite generative components (he called them “homeomerics”) required for our bodies. In fact, this Greek sage was the first to talk about nutrients! Hippocrates who lived around 400 BC looked even deeper, he noticed the healing power of good aliment by saying “Let food be your medicine and medicine be your food”. The years following medieval times brought even more revelations. Leonardo da Vinci, an artist and a scientist of the 16th century, reflected upon human metabolism comparing it to a burning candle. In the middle of the 18th century Dr. James Lind, a physician in the British navy, made a revolutionary statement - lime juice can save sailors from pain and sufferings of scurvy. Later the most vital elements like calcium, carbon, nitrogen, hydrogen and oxygen were discovered and recognized as the primary components of food.

The 19th century investigation revealed the importance of right balance of carbohydrates, proteins and fats. In 1930s vitamin C was discovered and it finally became clear what helped the sailors of the past get rid of scurvy. Every year personalities acquired more and more data about healthy nutrition able of preventing various health troubles and restoring health. By the end of the 20-th century we knew every tiny detail possible about every element, vitamin and mineral contained in food and favorable for our health. Theoretically it was a good thing because with this knowledge humanity could minimize health risks and use the power of nature to keep fit and healthy all our lives. Alas, the outcome turned out to be quite the opposite! Avid and resourceful men and women understood how to make fragile products last longer, how to manufacture cheaper staples with the help of synthetic additives and the modern nutrition Armageddon started!

With all the ads in mass media and all the bright and attractive wrappings you see on the shelves of supermarkets are you sure you remember what is nutrition? Let us remind you that nutrition is neither fashion nor cult! Nutrition is the provision of the elements necessary to your body cells and tissues in the form of food. This way you provide for life and promote every process taking place in your body. With regular healthy meals you can prevent as well as get rid of many common health issues. If you doubt as to the fact how rational is your diet, turn to one of the health professionals specializing in human nutrition - they are called dieticians. They will help you keep the best personal or family diet you require.

Nutrition as a science is interested in metabolic and physiological responses of the body to diet. Human organism has a comprehensible chemical composition. There are basic elements like carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, zinc, magnesium, manganese etc. Occurring in our body in different combinations, there elements make up water, carbohydrates (such as sugar, starch and fiber), amino acids (contained in proteins), fatty acids (contained in lipids), nucleic acids (such as DNA and RNA), hormones, vitamins etc.

Modern dietology speaks about six major classes of nutrients: carbohydrates, fats, minerals, protein, vitamins and water. Some of them are required regularly in relatively large amounts, that is why they are called macronutirents. These are carbohydrates, fats, protein, and water. Other elements are required regularly but in smaller quantities - they are called micronutirents. These are minerals and vitamins. Among other micronutrients favorable for certain systems of our body are antioxidants and phytochemicals. Lack of some nutrients can be responsible for poor health. Excessive amount of nutrients is just as ruinous - it can cause immediate death!

Let us check out the classes of the nutrient mentioned above in detail:

1. Carbohydrates can be easily found everywhere. They constitute a large part of foods like bread, noodles, rice and all grain-based products. They are an important part of the human diet and are processed into our bodies into sugars. Carbohydrates are good energy foods but beware - too much of them will result in negative health conditions!

2. Fats are long chains of carbon and hydrogen atoms. They can be saturated (those fats are solid at room temperature) or unsaturated (those fats are typically liquid). Saturated fats come from animal food; they are known in human nutrition for millennia. Unsaturated fats coming from vegetables and fish are believed to be healthier.

3. Proteins are very important for our life and health. The bulk of our body structures - muscles, skin, hair - consist of proteins. Our bodies process the proteins contained in the food to get different amino acids and build new proteins we need and replace ruined proteins. Some amino acids can be produced in our body, they are called-non essential. Others cannot be produced by our organism; that is why the are called essential. There are ten of them and they must always be included into your diet. Otherwise human organism will be unable to get mature, to overcome pregnancy, to produce breast milk for the offsprings, to heal the injury like a cut or a burn. Perfect protein sources are meet, soy, eggs, diary products etc.

4. Minerals are chemical elements very important for our body, too. The four of them - carbon, hydrogen, oxygen and nitrogen - can be found in any organic molecule. Other minerals are rather rare, and our body needs a tiny quantity of them. All the same, lack of any mineral can lead to considerable health risks. The most famous chemical elements we require are:
- Calcium (vital for digestive system health, bone strength, it helps clear toxins);
- Chlorine (vital for digestive system and the composition of blood);
- Magnesium (vital for peristalsis, bone strength, flexibility);
- Phosphorus (vital for bone strength and energy production);
- Potassium (vital for heart and nerve health);
- Sodium (vital for the composition of blood);
- Sulfur (vital for building new proteins) etc.

5. Vitamins are also vital for keeping fit and healthy. The only vitamin produced by our body is vitamin D - it is synthesized in the skin when a certain amount of UVB radiation gets on it. All other vitamins should be present in our meals. Lack of vitamins inevitably leads to serious diseases (osteoporosis, goiter, scurvy, immune system problems, premature aging, mental disorders etc.)

6. Water is the cornerstone of biological life. Our body has about 80% of water in it. We can live without food for weeks but it is impossible to survive without water for more than a few days. Every chemical process in our body takes place in water. No wonder it is so important to consume clear and safe water. An average adult requires as much as 6-8 glasses of water daily to function well.

The most tricky point is that your body needs a perfect balance of every element mentioned above. Otherwise you can face very serious illnesses! If you feel week and exhausted all the time, you definitely need a good nutrition supplement of essential vitamins and minerals!
