A lot of foods have a best by date. Usually all of the food in cans, bottles, boxes, and bags have a best by date. Food that doesn't have something protecting over it like fruit and vegetables doesn't have a best by date usually.
In most circumstances, yes, you can. The best before date simply means that after that date, the food may begin to lose quality.
If it smells ok, looks ok and you cook it at a high enough temperature it should be fine- food doesn't know it has a best before date people are way to wary nowadays
the use by date is that is advised to be eaten by... this does not mean to say that is has to be eaten if it is fine if it going moldy it is rotten so throw it away :)
Best before dates deal mainly with taste and performance, not food safety. For example, a cake mix that is beyond its "best before" date may not taste as good or may not rise as well. The cake, however, is fine to eat. I've never had a problem with a product consumed (well) after its best before date. Expiration dates tend to be more on refrigerated foods and should be consumed within a week or less after the date.
Centres which sell or give away food past it's best before date
mostly a week or two weeks before it expires
A "sell by" date means after this date the store should not be selling the food, at least not at full retail price. There is a window of time after the sell-by date before the food is spoiled.
because you might get sick from it. the food might be rotten after the expiry date and also, it wuldnt be as delicious as the taste before the expiry date
There should be a 'best by' date on the bottom of the container. Quality will not be guaranteed past that date.

When the expiration date has passed on food or dairy products when it's still on the shelves of a supermarket, it should be considered to be unsafe for eating or drinking. In some cases a food label will say. "best to eat after the food opened 10 days or less " for example, this is an item purchased before its expiration date. Once it's opened the above notice on the label should be followed.
