Am very interested, as too is everyone else, about the so called obesity epidemic and what may be causing it.  We all talk about the vast choice of ready to eat food that is available to us in the West that was not before but I think we also need to consider how this food is actually sold to us.  I remember shopping with my parents in the early 70s and it being such a treat to buy a Wagon Wheel, a little bottle of Cresta pop, a pineapple yogurt.  A single one of all these things.  Did you hear me?   Just one.  Everything now is multi-pack and if that multi-pack gets into your home......well, you know the rest.  Someone recently said that you say no once in a supermarket but continuously at home but that is the only way we can buy them.  Trust me, they know what they're doing.
