Now we keep searching the root of our numerous diseases. Meanwhile, the answer is very simple, it is our up-to-date ways of life, but we stubbornly refuse to accept this truth. Sorry to inform you that, turning away from the disaster is not the same as solving it. It will not go away! No wonder we keep stumbling and falling inside the vicious circle of our routine lives, jobs, dirty thoughts and endless diseases until finally we lose the game.

Let us analyze the most dangerous factors affecting our health and making our existence unbearable. Experts from all over the world tend to enumerate the following reasons of our numerous miseries:

- poor ecology - drinking unclean or bottled water, consuming fast food, inhaling smoky air;
- residing in big crowded cities with constant smog and noise 24/7 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 for hours and 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.;
- usual stress at work and in our family life;
- ignoring the necessity of staying in bed when we are ill, taking medicines that muffle the symptoms of flue, cold etc.;
- poor nutrition - because we are so busy we have irregular meals. When we finally decide to have a bite we stuff ourselves with junk food hardly ever chewing it.

Our ancestors used to remember that we are what we eat and they took greatest care of their food. 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 decades existed on cultivating land and trade. Unlike us, they drank clean water, consumed natural food, breathed in unpolluted air and had calm lives.

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

Agriculture that developed about 10 000 years ago in different parts 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 personalities received the diversity of vegetables and fruit as well. Due to farming persons finally enriched their ration with the availability of meats, milk and dairy products.

Preserving food was a sort of sacred deed - saving it from infestation and contamination risks was, in fact, a question of preserving human lives. The shocking fact is that early cooking was a sort of ritualistic activity, too. Persons kept to absolutely strict recipes and procedures thus receiving food of wonderful purity and consistency.

Now you realize, 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 kind 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 believe 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 nitrution 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, spoke about 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 stunning 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 research showed the importance of right balance of carbohydrates, proteins and fats. In 1930s vitamin C was discovered and it eventually became clear what helped the sailors of the past get rid of scurvy. Every year individuals 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 learned 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 power mankind could minimize health risks and apply the power of nature to keep fit and healthy all our lives. The shameful fact is, the result turned out to be quite the opposite! Mean and resourceful personalities realized how to make perishable foods last longer, how to produce cheaper staples with the help of synthetic additives and the up-to-date nutrition Armageddon started!

With all the advertisements in mass media and all the colorful 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 materials necessary to your body cells and tissues in the form of food. This way you support 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 problems. If you doubt your diet is rational, turn to one of the health professionals specializing in human nutrition - they are called dieticians. They will help you find the best personal or family diet you require.

Nutrition as a science is keen on metabolic and physiological responses of the body to diet. Human body has a comprehensible chemical composition. There are basic compounds like carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, zinc, magnesium, manganese etc. Occurring in our organism 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 needed 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 dangerous - 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 make up 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 common in human nutrition for millennia. Unsaturated fats coming from vegetables and fish are believed to be healthier.

3. Proteins are vital 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 produce new proteins we need and replace damaged 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 body 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. Splendid protein sources are meet, soy, eggs, diary products etc.

4. Minerals are chemical elements vital for our organism, 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 definite amount of UVB radiation gets on it. All other vitamins should be present in our meals. Lack of vitamins inevitably leads to serious health problems (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 unreal to survive without water for more than a few days. Every chemical process in our body takes place in water. That is exactly why 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 health troubles! If you feel hopeless and exhausted all the time, you certainly need a good nutrition supplement of essential vitamins and minerals!
