Vegetarian food ingredients, which are responsible for the right tuning , functioning, or in other words, a balanced growth of the human body and mind, are vitamins, minerals, starch, carbohydrates and fibre, essential for the all-round development of human being.  
  Vegetarian foods like fruits, vegetables, nuts, cereals,  legumes and dairy products - contain all the above energizing ingredients essential for human body and building up its resistance base.  
   In contrast, when we consider non-vegetarian food, besides  producing degenerative symptoms in human physiology, it contain considerable amounts of saturated fats, cholesterol and is infect, very prone to many health problems.  
   The argument put forward by many, that non-vegetarian food gives more protein, is also a misleading conception. The fact is that an excess of animal protein may lead to complications like osteoporosis and cancer of the colon, among others. Whereas, when we consider in totality, a vegetarian diet has all the required food ingredients including, of course, proteins, carbohydrates and natural fibre in a balanced quantity.

Vegetarian are falsely alarmed about not getting sufficient protein but we are yet to know of a diet  consisting of natural foods, resulting in protein deficiency, so long as we are not deficient in calories.    We need only six percent of protein of our daily required total calories and it is practically impossible to get below nine percent of calories in ordinary diets.  
Many claim that in food-eggs, meat and fish have the highest   content of protein, whereas various experiments shows that pulses, coarse grains, soybeans and nuts, among others, have an even higher percentage of protein. All this argument notwithstanding, human body needs only 6 percent of protein whereas any vegetarian recipe gives that minimum requirement. Besides, a vegetarian diet contains a lot of fibre, is minus saturated fat and cholesterol and is digestible in a less span of time comparatively. For comparative study look at the nutritional values of various food items given in the chart.  
“There is little evidence to show that muscular activities increases the need for extra protein. Dave scott and Sixto linares - the acclaimed fittest men in the world, are both vegetarians. Similarly, some very big names in the field of sports and athletes - Edwin Moses, Mussay Rose, Paarvo Nurmi, Bill Picking, Dara Singh, Gama, Milka Singh, P.T. Usha to name a few, all lived on vegetarian diets. More so, in the field of body building, as well, a Swede, Andrea Cahling, who was adjudged Mr. International in 1980, is a confirmed vegetarian  Similarly in India, Guru Hanuman is also a vegetarian. So does the list goes on unveiling itself in an endless sequence.  
 Apart from the above, a vegetarian diet provides carbohydrates in good quantities, which keeps the body in good shape and tone, injects the required doses of energy, besides providing the stipulated amount of vitamins and minerals, essential for the growth and development of the human-body. All the essential ingredients required to sustain and nourish the human-body being present in the vegetarian diet in a healthy, natural balance, what more could a person ask for ?  A healthy mind in a healthy body and that too without the ill-effects of meat, fish and eggs.  
The revolutionary study of the ex-health minister of U.K Ms. Edwina Quiry on the ill-effects of consuming eggs is also well known to everybody. Her revealing statement - “ Eggs may cause death” continues to have a far reaching impact on the consumption trends of eggs in England.  
In the demonstration given by energy-Providing ingredients in a vegetarian diet; dairy products leads the march. Dairy products are also a good provider of Calcium, though vegans have their own arguments about it. However, there is need for purity of milk and milk products as most are adulterated. 
Amino Acids, which are the building blocks, are the prime constituents of protein. They are present in plant and as such, a mix of various plant sources, in the form of vegetables, grains and pulses are the ideal pattern of diet for the vegetarians.  
Carbohydrates, the carriers of starch, sugar and fibres are found in plant foods, cereals, vegetables and the list goes on. Human body is tailor-made to be fed on a high diet of carbohydrates, ideally not less than 55 percent of the total food intake, whereas a non-vegetarian diet does not contain carbohydrates.  
Minerals and vitamins are found in rich quantity in plants and it is to be noted that the source of fibres are only in vegetarian foods. Dark green Vegetables are good sources of Riboflavin along with legumes and whole grain cereals.  
Plant fat differs from animal fat in two ways - firstly they are cholesterol - free,  and secondly they generally contain more polyunsaturated fats while they are also low on saturated fat contents.  
“Nutritional science is coming of age.. No other field of research seems to hold better promise for the prevention and control of cancer and other illness and for securing and maintaining human health.”- says John Robbins in the book” Diet for a New America’, while speaking on health and vegetarianism.  
Diet control is an effective tool, when dealing with ailments and generally medication, alone, does not help. Studies have revealed that of the study groups, ninety five percent of the persons, who lived on meat diets and have switched over to a vegetarian menu, have reported to have discovered in them, an increase in energy, vitality, and a general feeling of well being.  
It is therefore imperative that we are well informed and aware as to the ingredients of a good diet and develop a selectiveness in our food choices, more so, because it is the nature of our diet which contributes in  the ratio of more than seventy five percent towards the occurrence of our ailments.  
So, in fact, Vegetarians have been found by researchers to be not only the longest living but also enjoying full, active lives throughout their many years and show no signs of the various degenerative diseases that afflict meat eating culture.
