Take Cues From Traditional Wisdom
Diet is area and season specific and has developed over time from local resources, through trial and error. According to Ayurveda, every individual is a distinct entity and so Ayurvedic physicians recommended certain dos and don'ts in food intake based on the constitutional nature of the individual.
Genomic theory and pharmacogenomics also have similar conclusions. It is also now well-recognised that the expression of genes need the right kind of food. It is possible to genetically design food plants with desired nutritional composition that suits the genetic make up of an individual. Therefore nutraceuticals should meet specific requirements of an individual or a group of people.
Traditional communities of many countries including India have developed a range of dietary practices that are now recognised to have high nutritional value. Let's examine a few. Consuming watermelon or tender coconut water or local drinks such as panna (made from raw mango) or sattu (made from cereals), in summer and hot climates takes care of water loss and keeps the kidney efficient and functional. It also provides powerful antioxidants and protection from solar radiation. Similarly, the sambhar consumed in south India is highly nutritional and contains good protein, powerful antioxidants and components that help in preventing fluoride poisoning. The lentils, tamarind, mixed vegetable, asfoetida included in this recipe makes it a balanced and nutritious food supplement. Idli consumed in South India is also very nutritious and contains valuable proteins and vitamins such as B6 and B12.
Taking the cue from traditional knowledge and modern scientific knowledge, the National Botanical Research Institute has designed a range of functional foods and products for pregnant women, lactating mothers, infants, growing children, diabetics and the aged.
