Remember what you buy is what you will consume.
Aim
to shop the perimeter of the supermarket for the bulk of your items.
Center aisles contain some items you will require but also many
unhealthy products that you do not want to find their way into your
trolley.
Beware of packaging and advertising claiming to be diet, light,low fat, less or reduced fat these can often contain high amounts of sugar.
Turn products around and read the nutritional contents and compare one brand to others on the shelf before you decide.
