Unfortunately, it is cheaper to buy unhealthy foods than healthy. I try places like Costco, and Winco to get veggies that are more affordable. Also, I like to buy some of my veggies frozen, tho that may not technically be raw. I have found myself eating less foot in general when I focus on veggies and fruits. Hopefully your mother will end up being inspired by the changes that you go through. My mother is only 52 and her health is awful, mostly due to her poor eating and lack of exercise. She is already on like 15-17 different medications but she won't change her diet still.
