One of the most important elements of health protection is an adequate, or to be even more precise, a balanced and varied diet. A balanced diet covers energy and nutrient requirements, ensures the appropriate ratios of nutrients, while a varied (mixed) diet means the presence of different groups of foodstuffs and foods in the diet. Our food provides approximately 40 types of nutrients for the organism. According to their primary roles, they can be body constituents (proteins, minerals), energy providers (fats, carbohydrates) and regulators (vitamins, trace elements). The organism’s daily requirement of vitamins and trace elements is extremely low, ranging from a few micrograms to 100 milligrams, so it is far below even 1 gram. Still, despite their presence in such low quantities, their insufficient intake causes disturbances in physiological functions, and their absolute lack is incompatible with life.
We need to mention Funk, who was the first to extract a substance from rice bran in 1911 with which the disease, called beriberi could be cured. As it is a compound that is vital (Latin: vitalis) chemically containing an amino group, he named it vitamin. This is where the revolutionary word comes from. This historical review is more complete if we say: the factor Funk discovered was Vitamin B1, and today we also know that the chemical structures of various vitamins very much differ from each other. Medical science respects traditions and prefers traditional names; this is why the vitamin word remained in the medical terminology.
Fat soluble vitamins
One of the most important aspects of health care is a balanced, diverse diet. A balanced diet meets the energy needs of the body and provides nutrients in the necessary amount and rates. A diverse (mixed) diet means the consumption of various food groups and foods. Our food provides about 40 types of nutrients for our body. According to their primary roles, these are structural components (proteins, minerals), energy sources (fats, carbohydrates) and regulators (vitamins, micronutrients). As for vitamins and micronutrients, the daily demand of the body is very low, ranging from a few micrograms to 100 mg i.e. well below a gram. Yet, despite these extremely low amounts, insufficient intake causes sever dysfunctions and if they are not available at all, it is incompatible with life.
Water soluble vitamins
The most important thing we need to know about water-soluble vitamins is that the organism stores them only to a limited extent, so their regular consumption is essential for maintaining proper functions. We can often hear that any quantity of water-soluble vitamins can be consumed without the risk of side effects. As we can see among fat-soluble vitamins, such a summarising opinion might be misleading, because even fat-soluble vitamins differ regarding toxicity. And it also holds true the members of the water-soluble group.
These substances cannot be clearly listed among vitamins, but their application is useful and completely safe for the organism.
