In order to eat healthy, I had started having raw garlic and ginger with my meals. Then a friend told me these raw herbs may affect my delicate stomach. So I started "pickling" the herbs in vinegar. Is my friend right? Also, will vinegar diminish the beneficial effects of the herbs? SP TanejaDr Ishi Khosla, clinical nutritionist and director, Whole Foods, says: Ginger and garlic have several health promoting properties, which also includes the digestive system. They are unlikely to cause indigestion unless there is active inflammation of the gastrointestinal tract. There are certain anti-infective properties which may be lost by pickling in vinegar. If indigestion is persisting over a long period, it is better to seek advise from a qualified gastroenteritis specialist.Next week, MV Padma Srivastav, Professor of Neurology, AIIMS, will answer queries on stroke.
