that could be one of the problems, along with others. When we were kids, there were no ice packs to put
in any lunch, and some people didn't have refrigerators, only ice boxes, so great care, and everyday
shopping had to take place to make sure food was very fresh all the time.
no thermal lunch bags, just brown paper lunch bags, or a metal lunch box,
and there wasn't even anything plastic yet.
There were lots of little grocery stores in neighbourhoods, so one could drop by and pick up fresh food
for tomorrows lunch easily, the only big store in my town for food shopping was the first 'overwaitea'
ever, and it was about the size of a big drugstore, and way downtown, had to take the bus to shop there.
With many kids packing their own lunches today, because most parents work, and chores are varied, I would
be very careful about the food they are taking with them, and as the parent I would know exactly what
is in my frig, and just how fresh the food is, checking dates on packages, etc, and milk products.
At least now it is good to see that the schools have upgraded their supplies of food for the kids, so
its not all about popularity of products now, but 'nutrition' as well.
Kids can be so careless in the kitchen, leaving food on counters after snacks, etc., and no parents there
to observe, causing food to deteriorate, then it goes back into frig later, then back out for lunches,
poor habits for keeping food fresh, then if it sits around the school for 3 or 4 hours, more problems.
We used to get a lot of that canned meat spread in our sandwiches- it came in very small cans - probably 3-4 oz. enough to make about two good sandwiches. It wasn't too bad, sure beats baloney. I haven't checked lately to see if they even sell that stuff any more. Too much fancy stuff today and far too much packaging.
