Human body requires nutritious food for sustenance. A person may not be healthy just because he is consuming enough or more food. It can be seen that there are people who eat well but always suffer from health problems. The reason is that despite eating sufficient food the body is not getting the necessary nutrients required to keep a person healthy. Over eating is equally harmful as starving as far as the body is concerned.
In such cases, a balanced diet is the answer for the problem. A balanced diet is one which contains sufficient quantities of proteins, fats and carbohydrates. Proteins are supplied by meat, fish, egg, cheese, milk etc. Fat is provided by butter, cream, milk, oily fish, nuts etc. We get carbohydrates from sugars, starches, cereals, oatmeal, rice, fruits and potatoes.
Apart from this the body requires certain minerals like calcium and prosperous which are found in milk and fish. Certain other minerals are iron, manganese and copper supplied by egg yoke, peas, spinach etc.
However, many people are unable to eat a healthy and well balanced food for various reasons. Further, some of the nutrients are difficult to get absorbed in sufficient quantities. Our food should have enough of the above nutrients, but very often they are lost while they are cooked or during improper storage. Due to various reasons food items get contaminated and loose its nutritive values. In such circumstances, the deficiencies can be met with health supplements.
Vitamins, which are also essential for a good diet, are complex organic substances that are present in animal and plant tissues. Essential for human bodies to protect it from aliments as well as to conserve sufficient energy required for a healthy life, everyone should take sufficient quantities of vitamins. The word vitamin comes from “vita” the Latin word for life. There are two types of vitamins. Water soluble and fat soluble. Vitamins B1, B2, B3, B6 and B12 as well as biotin, Pantothenic acid Vitamin C and folate are water soluble. Vitamin D, E, A and K are fat soluble. The fat soluble vitamins are stored in the fat deposits in our body.
The human body requires both vitamins and minerals to strengthen the immune system. Both these vitamins and minerals are found in abundance in plants and animal tissues.
As already mentioned above, when the body cannot receive nutrients sufficiently, health supplements will provide them to support the system. For example, a person with Vitamin D deficiency will be given cod liver oil which contains fatty or folic acids. Essential nutrients like omega 3 oils in fish, will provide the body enough of it, if taken as a supplement. Vitamin and minerals in natural organic foods are absorbed by the body and stimulate much easier and faster. Lots of vegetable and fruits should be consumed to make the food a well balanced one. There is no substitute for a well balanced diet. However persons who suffer from malnutrition and consequent ailments are given health supplements by physicians in the course of treatment. There are many health supplements patented and marketed to administer effective treatment in such cases.
While food supplements are necessary in many cases, researches have revealed that excess use of supplements at times, will cause negative impacts on the body. For example, frequent use of Vitamin C supplements can cause Arthrosclerosis or hardening of arteries. At the same time Vitamin C obtained from natural food act as an antioxidant that helps to prevent diseases. It is better to eat nutritious food than taking tablets. We must know that three different factors contribute to ill health; deficiencies, excesses, and imbalances. In fact a good health care initiative should include preventive, curatives and palliative interventions according to World Health Organisation.
In this context it will be interesting to note that UK currently spends 17 billion pounds a year on diet related diseases. If this is the state of a developed country, imagine the conditions prevailing in the less developed parts of the world where people suffer from hunger.
