An estimated 80 percent of India's population identifies as Hindu, and the traditional Hindu diet is vegetarian. In the traditional yogic text the Mahabharata, a vegetarian diet is said to be sattvic -- meaning that it is linked with purity, goodness, and enlightenment."The practitioner of yoga has to adopt a vegetarian diet in order to attain one-pointed evolution and spiritual evolution," master practitioner B.K.S. Iyengar writes in "Light On Yoga."Additionally, a vegetarian diet has been linked with major health benefits, including increased longevity and a lower risk of diabetes, heart disease, and high blood pressure.They have strong family values.In Indian culture, there is a strong emphasis on family as the primary social unit, and families tend to be large, providing a strong social support system and network of community ties (a key factor in longevity). Indian families often live together in multi-generational "joint family" units."Through a multitude of kinship ties, each person is linked with kin in villages and towns near and far," according to the Asia Society. "Almost everywhere a person goes, he can find a relative from whom he can expect moral and practical support."They cook with turmeric. Turmeric is a popular spice in Indian cooking, and it's a superfood that can boost longevity and ward off illness. The spice has long been used medicinally in the Chinese and Indian traditions, and for good reason: Turmeric is packed with anti-inflammatory properties, and is also anti-carcinogenic, anti-fungal and anti-bacterial. Plus, it makes a delicious (and colorful) curry.They're making low-cost health innovations. Although the Indian health care system is often criticized (and is certainly an overburdened system), some Indian institutions have succeed in creating a model for good-quality health care at a low cost."U.S. hospitals would do well to take a leaf or two from the book of Indian doctors and hospitals that are treating problems of the eye, heart, and kidney all the way to maternity care, orthopedics, and cancer for less than 5% to 10% of U.S. costs," Vijay Govindarajan and Ravi Ramamurti write in a recent Harvard Business Review blog, explaining that the Indian hospitals they studied still met international care standards.
