These days we keep searching 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 truth. 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 stumbling and falling inside the vicious circle of our routine lives, jobs, dirty thoughts and endless diseases until finally we give up.

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

- poor ecology - drinking unclean or bottled water, eating junk food, inhaling awful air;
- residing in big crowded cities with constant smog and noise on a twenty-four hour basis and no privacy at all to restore our nervous system;
- lack of healthy sleep - we choose to entertain or take extra jobs instead of having a good sleep;
- lack of physical exercise - our bodies were designed to run, jump, climb, bend and perform hundreds of other activities 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.;
- daily stress at work and in our family life;
- forgetting about the necessity of staying in bed when we are sick, taking meds that hide the symptoms of flue, cold etc.;
- poor nutrition - because we are so busy we have irregular meals. When we at long last make up our mind to have a bite we gobble fast food hardly ever chewing it.

Our ancestors used to remember 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. When the tribes and nations became settled many generations of individuals for hundreds of years existed on growing plants and animals and trade. Unlike us, they drank pure water, consumed natural food, inhaled fresh air and had peaceful lives.

The diet of ancient people differed significantly because of climate and season change. Depending on location the diet in the southern parts was based on plant foods. At the same time in the northern parts the diet of our ancestors was based on animal products.

Agriculture that started 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 historical epoch we can speak of the first staples such as bread, pasta and tortillas. At the same time ancient persons 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 kind of sacred action - keeping it safe it from infestation and contamination risks was, in fact, a question of preserving human lives. The thrilling fact is that early cooking was a type of ritualistic activity, too. Individuals kept to extremely strict recipes and procedures thus receiving food of wonderful purity and consistency.

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

Our clever ancestors knew that you cannot survive without good top-quality food. Ancient Greek sage Anaxagoras was the first human to declare that food is absorbed by the human body. Anaxagoras was sure the staples contain certain generative components (he called them “homeomerics”) needed 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, 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 shocking statement - lime juice can save sailors from pain and dangerous complications 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 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 people acquired more and more information about healthy nutrition able of preventing different health problems and restoring health. By the end of the 20-th century we found out every tiny detail possible about every element, vitamin and mineral contained in food and favorable for our well being. In theory it was a good thing because with this power mankind could minimize health risks and use the power of nature to keep fit and healthy all our lives. The shameful fact is, the outcome turned out to be quite the opposite! Greedy and resourceful humans realized how to make perishable products last longer, how to manufacture cheaper foods with the help of synthetic additives and the up-to-date 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 bear in mind 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 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 illnesses. If you doubt your diet is rational, find 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 interested in 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 compounds 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 needed 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 some 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 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 many centuries. Unsaturated fats coming from vegetables and fish are considered 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 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 very important 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 essential 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 illnesses (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 stay alive 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 health issues! If you feel helpless and exhausted all the time, you definitely need a good nutrition supplement of essential vitamins and minerals!
