      CHAPTER I

      INTRODUCTION

      What are vitamins?

      A vitamin is an organic compound required by an organism as a vital nutrient, but in tiny amounts. Such a nutrient is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, hence must be obtained from the diet. Despite the attention vitamins get today through media few people know what vitamins are and how they work in our body.

      Most of us, adults as children, are aware of the fact that vitamins and minerals are necessary for having a good health, and are important for preventing some diseases. Yet, not many people know how important vitamins and minerals are for our physical and mental well-being.

      Vitamins or natural vitamins are organic substances, and they must be made of living plants, animals or in our body. They can also be produced synthetically, but even in this process, they are often made by living organisms. It was only around the turn of the century, that some began to understand that there was more to food than just proteins, carbohydrates, fats and minerals. Laboratory experiments showed that although all these nutrients were present, one could find cases of malnutrition. Researchers began looking for the missing link in the food chain and hence vitamins were discovered. There have been found 13 types of these very important nutrients which are universally recognized as vitamins. However, some experts believe that perhaps there are many left to be discovered.

      There is a continious vitamin research, and most importantly is the research that gives us knowledge about how these substances affect and function in our body.

      The first vitamin discovered was vitamin B1 (Thiamine) in 1910. Vitamin A or Retinol was found in 1913. In 1920 the vitamins; C (Ascorbic acid), D (Calciferol) and B2 (Riboflavin) were discovered. In 1922 vitamin E (Tocopherol), in 1926 vitamin B12 (Cobalamins) and in 1929 vitamin K1 (Phylloquinone and in 1931 vitamin B5 (Pantothenic acid) and vitamin B7 (Biotin) 1934 Vitamin B6 (Pyridoxine). In 1936 vitamin B3 or Niacin. Then in 1941 vitamin B9 (Folic acid).

      Experiments and studies continue to give us new and useful knowledge about all these vital compounds. There are indications that we have only gone a short distance in the knowledge about vitamins.

      Vitamins are either classified as water-soluble or fat-soluble. Vitamin C and the B vitamins are water-soluble and vitamins A, D, E, and K are fat-soluble.

      Water-soluble vitamins dissolve in water, and are normally readily excreted from the body via urination and one can see or predict from the urine our vitamin consumption. As these vitamins are not stored in our body, a consistent intake is important. Many types of water-soluble vitamins are synthesized by bacteria.

      The fat-soluble vitamins are absorbed through the intestinal tract with the help of fats. They accumulate in the body, and one has to be aware of the likelihood that the fat-soluble vitamins can be overdosed.

      Do we need vitamins?

      All our bodies and organs need vitamins and minerals. Not just once in a while, but all the time. The different organs and body parts, directly or indirectly, use vitamins and minerals in processes such as digestion and metabolism. When a function is to be started like digestion of food, it needs a catalyst. In our body, such a catalyst is called an enzyme. You can say enzymes act like spark plugs do in an engine. Enzymes are required for almost all biochemical processes such as digestion, cell renewal and growth.

      An enzyme is composed mostly of a protein molecule which is associated with a coenzyme. Often a coenzyme is a vitamin in itself or it may consist of a substance prepared from a vitamin or mineral. Our body cannot produce such coenzymes, therefore it is vital that essential vitamins and minerals are added continuously into our organism. A lack of only one vitamin may cause various diseases. This is because vitamins and minerals often work best together and because they affect nearly every function in our body.

      Dr. Bruce Ames, a well known biochemist at the University of California, has hypothesized that when the intake of vitamins and minerals is lower than the recommended levels, short-term requirements for such micronutrients in metabolic reactions take precedence over long-term needs, thus resulting in long-term, cumulative oxidative damage to macromolecules as DNA and RNA. Proteins decline in mitochondrial function, accelerates cellular aging and may lead to an increase of risk of age-related diseases. Micronutrient intakes at the Recommended Daily Allowance (RDA) would allow sufficient amounts for normal metabolism. Intakes of the RDA or higher may be needed for optimum health promotion and chronic disease prevention.

      Should we take vitamin supplements?

      Everyone knows that vitamins are found in vegetables, fruits, meat, and fish, but do we get enough vitamins in the foods we normally eat? Some argue that we do.

      If we have a good, varied and balanced diet and live a life without any stress, yes, most likely we do get enough vitamins and minerals from the food we eat. Thus any extra supplements should not be necessary.

      However, only a few of us have such a perfect diet that would supply adequate vitamins and minerals. In addition, most of us have a busy and demanding lifestyle. People living in heavy polluted cities with stressful jobs and with little time to make sure the nutrition is optimal, would benefit from taking a regularl supplement of vitamins and minerals. Sometimes we get ill and these supplements will help us to recover more quickly making sure the body is supplied with adequate nutritions. However, supplements do not replace a good balanced diet !

      Much of the foods we eat are cooked or fried or have been prepared in ways that destroys a part of the important substances we need. Many people get their daily calorie intake from eating too much snack food and sweets. Most often these substances provide little or no vitamins and minerals. Therefore additional supplements are even more necessary. Other factors that increase our need for extra supply of vitamins and minerals are stress and disease. A person can still hold out with an inadequate or poor diet
