It is important to know how to correctly pronounce words, especially because in some cases one little sound is all it takes to transform one word into another one with a completely different meaning.
Let's use the fourth word above as an example. "Food" is pronounced (fud). The other option, (fut), refers to a different word, "foot", which has a completely different meaning. If you say you like spicy foot, people will certainly look at you with astonishment. However, if you say you like spicy food, not one will be surprised. Foot is a part of the body. Food is what we eat to obtain energy and stay alive.
