Total sales for the quarter rose 6.7%, or 5.1% excluding fuel, and the supermarket chain said it had delivered £2.7bn of sales growth since March 2005.
Sainsbury's also revealed it had teamed up with British Land to create a £1.2bn joint property venture. Sainsbury's will invest £273m in the new firm and hold a 50% stake.
It has also launched a 'feed your family for a fiver' campaign to provide customers with a range of healthy meals for four people for £5 or under.
“The market remains competitive but as we enter our fourth year of growth, the improvements we have made to date position us well to meet the demands of what continues to be a challenging environment,” said CEO Justin King.
