Brief History

Walnut occupies an important place in the healthy food items of human beings for thousands of years.  It is perhaps the oldest tree food and dates back to almost 7000 BC. It is believed that English walnuts originated from Himalayan region of India and erstwhile Persia. The Romans called it Juglans Regia which means “Food of Jupiter”.  In Persia the Walnuts were reserved for royals.  

Modern Research

According to a new research by a team from University of Scranton, Walnuts have the highest amount of the most powerful anti-oxidant, polyphenol, among a group of nuts. The potency of the
anti-oxidant in terms of quantity and quality has been found to be almost double compared to any other nut. It is a well-known fact that antioxidants neutralizes the free radicals responsible for serious health problems like cancer, heart disease, pre mature aging and cell death. Polyphenols, a type of antioxidants have been found to reduce LDL and protect heart by slowing down plaque build-up.  It is a good source of high quality protein, fibre and alpha – linolenic Acid (ALA). It has already been established that walnuts are a great source of omega-3 fatty acid, the food for the brain.
