Here is the outside edge (periphery) of our local supermarket:
Here's the interior (center) of the same supermarket:
Can you see the difference? Stay on the periphery!
At present I find most grocery stores a battleground. I do not want to see a lot of what is in the aisles. I do not want to see shelf after shelf, brand after brand of items I really never purchase (I do not want to offend you at all that I do not ever purchase an item that you like, so let's just say instead that everything that included wheat was inapplicable to me for seven years while my first son's wheat sensitivity was in play). I have my list, I go quickly to the produce aisle, to the meat and to the dairy and I am done. Once a month I purchase to fill the pantry back up with the basics. Then I concentrate on that. But when I do my weekly shopping I am on a battleground sticking to my plan, trying to resist the push.
However, every time I shop, I will see something on the shelf which will make me reach for it, a new yogurt, a new wheatless granola, a box of ravioli ... only to find that the item contains HFCS or three times the sugar I like, or 20+ ingredients. This is disappointing and makes me defensive, hence the feeling of battlefield. I have not found a good solution yet, but it drove me to try alternatives to the grocery store, to order weely fresh produce, different grains and flavors and beans directly from the farm where they are grown.
