After dropping to a 20-month low in mid-July, food inflation inched up to 8.04 per cent for the week ended July 23 on expensive onion, fruits and milk.
Food inflation, measured by the Wholesale Price Index (WPI), was 7.33 per cent in the previous week, the lowest since November 2009.
The rate of price rise of food items was 16.27 per cent in the corresponding week of July 2010.
As per the official data released today, onion became dearer by 26.36 per cent year-on-year and fruits were expensive by 15.97 per cent during the week under review.

Headline inflation stood at 9.44 per cent in June. The RBI has already hiked interest rates 11 times since March, 2010, to tame demand and curb inflation.
In its Economic Outlook for 2011-12 released earlier this week, the Prime Minister's Economic Advisory Council projected headline inflation to remain high at around 9 per cent till October. The rate of price rise will ease from November, declining to around 6.5 per cent by March 2012, it said.
The report also said that while pressure from food inflation has fallen in recent months, the rate of price rice still remained quite high with the possibility of further surge in the coming months.
