out of date bars

Hi i came off of the diet a few months ago and still have a weeks worth of supplies.
Just noticed that the bars went out the end of April. Will it harm me if i eat them in the next couple of weeks i have 9 peanut ones and was gonna do 2 shakes plus a bar a day.

Seems like such a waste ........
please help :-(

I always think, the label says "Best before" not "Bad after". I would not keep them for much longer, but eat them.

i had a load of out of date sachets when i started again this time.
i had them all anyway. they tasted the same.
