True

Explanation:

Depending on the food the expiration date can be very important to check before buying. If you buy milk and it is expired you can get very sick, as milk tends to get chunky when it expires and it spoils. Other food like vegetables or fruit only stay good for so long so it is good to know when they expire, so you are able to eat them prior to the expiration date. Chicken and steak are also good examples of this because if you eat either of these foods after they expire you can get sick with food poisoning.
