What Are Some Healthy Foods You Can Buy From The Shops?

As much as possible, stay away from processed foods which are pretty much most things that come in a box/bag/can. I read once that the way shops are set up, the foods that are better for you are generally on the perimeter isles and most stuff on the isles in the middle is what you should avoid as much as possible (exception for frozen fruits & veggies)

My shopping list is basically:

Fresh fruit and veg:
Spinach
red onions
chestnut mushrooms
whatever veg is in season (squash, broccoli, courgettes, asparagus)
salad veg - tomatoes and cucumber
