Allah tells us in the Quran: Then let man look at his food (80:24).
Let's say that your mother cooked a fish for you to eat and you are living in Canada and this fish came from Bangladesh. Now Allah tells us to look at our food to see where it came from, how it came from, how it was created, etc. Allah created this fish in a river of Bangladesh. Then Allah gave it food and looked after it so that it grows up. At one time, Allah caused a fisherman to catch the fish and sell it to a foreign export company. Then Allah caused the company to send the fish all the way to Canada. In Canada, someone went and bought that fish from a store. Then the fish was cooked and served in front of you. All these things Allah did just so that you can eat!
