I'm surprised by your estimate of food cost of $21.26 per day per person. My husband and I used to spend approx. $125 per week on groceries; in the last few months that has increased to $150- 160 per week; so $640 max. per month for the two of us. We don't eat red meat and use non dairy milk but we do eat chicken and fish, We always have lots of fresh fruit and vegetables so I believe we have a very healthy diet. We live in a small Ontario town that I've always believed has higher food prices than larger centers.
