Wisdom in Traditional Indian cooking
According to a US-based researcher of Indian origin, Murali Doraiswamy of Duke University, North Carolina, eating spicy Indian curry once or twice a week could help prevent the onset of Alzheimer’s disease and dementia. Curcumin, a component of turmeric, appears to prevent the spread of amyloid protein plaques, which are suspected to cause dementia. At the annual meeting of the Royal College of Psychiatrists in Liverpool, he said there was evidence that people who eat a curry meal two or three times a week had a lower risk of dementia.
Curcumin has been known to be good for memory as it has been shown to be have both neuroprotective and memory-enhancing properties, according to researchers at the U.S. Salk Institute, one of the world’s leading research centres. Curcumin is also a powerful antioxidant and one theory is that it acts as a scavenger, attacking free radicals that damage the nerve cells involved in memory and mental functioning. Some research shows that South Asian populations, who are among the highest users of the compound, have low rates of Alzheimer’s.
But turmeric is not the only curry ingredient with health promoting qualities. A list of other spices have been reported to have numerous medicinal properties. It is amazing how ancient Indian wisdom had incorporated use of these as spices into traditional forms of cooking.
