We're a family of 4- 2 adults, 2 kids- and I spend $90 a week, that is including food and non-food items like toiletries and cleaning products, and also dog food. Our entertainment budget is $120/month. I also cook from scratch a lot, and it's cut down on our trash.
I think there is a place you can read about the average grocery spending on
www.stretcher.com.
