Groceries: What is the average percent of the total income spent on food?

The food-at-home CPI for the second quarter of 2014 was 2.3 percent higher than the food-at-home CPI for second quarter 2013, as most at-home food categories increased in price, some over 10 percent. Lower prices for fats and oils and nonalcoholic beverages partially offset higher prices for most meats, fish and seafood, fresh fruits, dairy, and eggs. Year-over-year increases in retail beef and veal, pork, and egg prices were the largest since the fourth quarter of 2011.
