Our immune system arms such an extraordinary security system against enemies that our immune system still continues to baffle scientists! Inspite of the advancement of modern science, no alternative can be found for the immune system. Our body immune system is the top physician in the universe - it is very powerful and effective than any medication. To maintain our immune system in best form, vegetables and fruits diet is the solution.

Take the example of two person contaminated to the same recent swine flu break out. One individual falls seriously sick but the other does not fall ill. Although they face the same viral attack, only the person with a weak immune system becomes sick with the flu.

Studies by World Health Organization (WHO) and the United Nations Food and Agriculture Organization (FAO) report that as developing countries become increasingly urbanized, even traditionally vegetarian societies - the Chinese and Indians are going for high-fat, meat-rich diets over high-vegetable ones. The report also talked that the prevalence of heart disease in China and India is higher than all developed countries put together. India is thought to have the world's major diabetic population.

On the other hand, South Korea, which still takes a vegetarian diet, shows lower fat intake and lower rates of chronic diseases than countries of similar economic status.

The statistic above is caused by the fact that our immune system becomes stronger on a healthy diet and sufficient rest, poor nutrition and stress can cause us fall sick quicker.

Wholesome plant foods are rich in vitamins and minerals. Certain plant foods, for example soy are also rich in protein. Scientist have stated that vegetables and fruits provide estimated 40 nutrients or more. For an instance, an orange has a healthy amount of vitamin C, in addition to beta-carotene, d-Limonene, folic acid, potassium, calcium and many other nutrients.

Everyone of us would hope to live long, healthy lives, free of chronic illnesses like cancer, heart disease, hypertension, diabetes, stroke and osteoporosis. But large majority of us still eat unhealthy foods whenever we want and as much as we want, without considering the consequences.

If we choose the best fuel for our vehicles, why don't we take healthy vegetarian diets for our bodies?
