What Are Vitamins?
Vitamins are organic compounds that are required by the body in very small amounts for normal growth and maintenance of good condition to occur. Vitamins play vital roles in the metabolic processes of the body and a insufficiency state for a single vitamin will manifest with characteristic symptoms. Vitamins are broadly categorized into two types: Water Soluble Vitamins and Fat Soluble Vitamins.
Water Soluble Vitamins
The water soluble vitamins consist of Vitamin C and the Vitamin B complicated group. They are so-called water soluble vitamins because they are no ifs ands or buts and quickly lost in the urine and are not stored in the body. Consequently deficiencies of water soluble vitamins occur much more rapidly than those of fat soluble vitamins. Conversely, since water soluble vitamins are not stored in the body it is highly difficult to attain toxic levels.
Fat Soluble Vitamins
The fat soluble vitamins include: Vitamin A, Vitamin D, Vitamin E and Vitamin K (use the acronym Adek to remember). These vitamins are classified as fat soluble since they are soluble in fat and are absorbed by the body from the intestinal tract. As they corollary the same path of absorption as fat any condition or factor that interferes with fat absorption also interferes with their absorption. Because these vitamins are more readily stored in the body than the water-soluble vitamins, deficiencies occur less frequently and take longer to occur. One drawback of being soluble in fat and thereby readily stored in the body is that toxic levels are more no ifs ands or buts attained with these types of vitamins.
Why Supplementing With Vitamins Is Good For You
The American curative connection (Ama) currently encourages all adults to supplement daily with multi-vitamins. What is of single note here is the fact that for the past 20 years plus, the Ama has strongly stood against supplementing with vitamins. So why the change? Following a landmark divulge covering 38 years of scientific investigate by Harvard researchers, the June 19th 2002 edition of the Journal of the American curative Association closed that although the current North American diet is sufficient to preclude vitamin insufficiency diseases (such as scurvy), it is insufficient to promote good health. Furthermore, recent studies have shown that insufficient vitamin intake has a direct correlation to the amelioration of lasting diseases such as osteoporosis, cardiovascular disease and cancer as well as other degenerative diseases.
Anti-Oxidant operation of Vitamins
Vitamins have some dissimilar functions, any way detailing the dissimilar ways in which each private vitamin works is beyond the scope of this article. Having said that though, I will touch on the anti-oxidant operation of vitamins because it truly highlights the point of vitamins.
Energy creation within our bodies (specifically, within cells) occurs straight through the replacement of electrons from one molecule to the next. The process by which an electron is lost is called reduction and the opposite process by which an electron is gained is called oxidation. The oxidation-reduction (redox reaction) reactions that occur within our cells to create vigor are what is known as cell respiration. One of the side effects of cell respiration is leaking of electrons complicated in cell respiration from the respiratory centers of the cell. These escaped electrons then react with ambient oxygen to form what are known as free radicals (note, some other factors cause free radical formation including: environmental pollutants, smoking, vigorous exercise, pesticides to name but a few).
What are free radicals? They are molecular fragments that are characterized by having an unpaired electron which makes them highly volatile. Because of their unstable and vaporing nature they react especially aggressively with other molecules from the instant they are created and over time the cumulative damage unleashed by their operation destroys molecular integrity which spreads to the cell, then to tissues, onwards to organs and ultimately affects the entire organism to manifest as degenerative disease associated with aging, as well as accelerated aging process. To date an estimated eighty to ninety percent of degenerative diseases are believed to be associated to free radical activity.
Several vitamins are known mighty anti-oxidants and act as protective buffers within our cells to counter the destructive corollary caused by constant free radical activity.
So to summarize, although vitamins have many other considerable functions within our bodies, their anti-oxidant operation alone should be intuit sufficient for whatever to seriously think supplementing with vitamins if they aren't already.
