www.ChooseMyPlate.gov. The new MyPlate icon emphasizes the fruit, vegetable, grains, protein and dairy food groups." excerpt from the USDA Press Release
I was quite surprised by the Sample Menus for a 2000 Calorie Food Pattern. This document can be found on ChooseMyPlate.gov under News & Media.
The menu says that "While this 7-day menu provides the recommended amounts of food and key nutrients, it does so at a moderate cost. Based on national average food costs, adjusted for inflation to March 2011 prices, the cost of this menu is less than the average amount spent for food, per person, in a 4-person family."
This menu uses over 100 ingredients and quite often just a portion of a canned item... And, while I understand you would need to multiply that quantity by 4 I don't think the math makes this cost effective.
So - I've made a summary of all of the ingredients, and during lunch today I am going to try and price common sizes. What do you think, could you feed your family this 7-day menu on your current grocery budget?
