These days we keep searching the root of our numerous health issues. Meanwhile, the answer is clear, it is our contemporary life styles, but we foolishly refuse to accept this fact. It is important to note that, turning away from the problem is not the same as solving it. It will not go away! No wonder we keep wandering inside the vicious circle of our hackneyed lives, jobs, wicked thoughts and endless health issues until finally we break down.

Let us analyze the most dangerous things ruining our health and making our existence hopeless. Experts from all over the world tend to underline the following reasons of our numerous disasters:

- poor ecology - drinking unclean or bottled water, eating junk food, breathing in polluted air;
- living in big crowded cities with constant smog and noise round the clock and no privacy at all to restore our nervous system;
- lack of normal sleep - we prefer 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 activities 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.;
- constant stress at work and in our family life;
- forgetting about the necessity of staying in bed when we are sick, taking medicines that suppress the signs of flue, cold etc.;
- poor nutrition - because we are so busy we have hasty meals. When we in the end decide to have something to eat we swallow junk food without chewing it.

Our ancestors never forgot that we are what we eat and they took greatest care of their foodstuffs. As you all know, humanity started as hunter-gatherers about 250,000 years ago. When the tribes and nations became settled many generations of men and women for years and years lived on cultivating land and trade. Unlike us, they drank pure water, ate natural food, breathed in fresh air and had unhurried lives.

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

Agriculture that started 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 historical epoch we can speak of the first staples such as bread, pasta and tortillas. At the same time ancient personalities got the diversity of vegetables and fruit as well. Due to farming people finally enriched their ration with the availability of meats, milk and dairy products.

Storing food was a type of sacred action - saving it from infestation and contamination risks was, in fact, a question of survival. The fascinating fact is that early cooking was a type of ritualistic activity, too. Persons kept to extremely strict recipes and procedures thus receiving food of wonderful purity and consistency.

As you can see, mankind 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 having porridge, boiled potatoes, or cooked lean meat - we have a type of genetic ability of digesting it!

Our wise ancestors knew that you cannot survive without good top-quality food. Ancient Greek sage Anaxagoras was the first man to think 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 recognized 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 revolutionary statement - lime juice can save sailors from pain and sufferings of scurvy. Later the most important elements like calcium, carbon, nitrogen, hydrogen and oxygen were discovered and recognized as the primary components of food.

The 19th century research 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 humans acquired more and more data about healthy nutrition able of preventing different health disorders 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. Theoretically it was a good sign because with this knowledge humanity could minimize health risks and apply 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! Avid and resourceful humans understood how to make perishable products last longer, how to manufacture cheaper staples with the help of synthetic additives and the contemporary nutrition Armageddon started!

With all the ads in mass media and all the bright and thrilling wrappings you see on the shelves of supermarkets are you sure you remember what is nutrition? Let us remember 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 disorders. If you doubt your diet is rational, address 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 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 needed 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 some systems of our body are antioxidants and phytochemicals. Lack of some nutrients can be responsible for poor health. Too much 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 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 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 majority of our body structures - muscles, skin, hair - are made 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. Great 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 organism 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 always 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 stunning point is that your body needs a fragile balance of every element mentioned above. Otherwise you can face very serious health problems! If you feel tired and exhausted all the time, you certainly need a good nutrition supplement of essential vitamins and minerals!
