Nooyi, named late last month the world's most powerful business women, mostly has a bowl of Quaker oatmeal with Tropicana juice for her breakfast, she said in a media interview.

Then for lunch, she has Lay's Kettle chips and Mirinda Orange. For dinner, Lays chips are again one of her favourites.

Besides, she always takes half a glass of Pepsi whenever her daughter is sipping it, Nooyi told the Wall Street Journal adding her 15-year old daughter drinks Pepsi every day.

When asked why beverages are being hit harder than snacks by the economic slowdown, Nooyi said that there used to be a lot of wastage earlier as "people unscrewed their bottle and did not finish it all. Now they are carrying the bottle longer and finishing the beverage."

Quoting a grocery store operator, Nooyi said that it used to have a number of construction workers asking for "Mountain Dew" in the morning. But due to slump in the housing market, those consumers are doing without the drink.
