What is food? You can eat bread until we fill our belly and feel just the same as after eating a huge steak.
Hmm, wait, I think there are some valid points here.
What is food, that is a good question. Normally we take for granted what constitutes food and what doesn't, but somewhere along, in history, some persons had to figure out what was edible and what wasn't. Perhaps, not all foods had to be "learned", as it may have been instinctual for our early ancestors to know what to and what not to eat.
But, think of something like cheese. It really would seem like something that should not be eaten. Part of the process of making cheese is to add bacteria and then to let it age. Most foods go bad if you let them sit out for too long. When a food goes bad it will often have a foul or strong odor. Many cheeses are aged (allowed to sit out) and have a foul or strong odor. Cheese basically has the same properties of spoiled or rotten food, it's old and it smells bad. Yet, someone gave the old smelly cheese a try, enjoyed it and lived.

Origins of Cheese]
The idea of this makes me wonder who discovered what things are edible and what things aren't? The person who discovered cheese, why did they take the risk of eating something that probably appeared to be rotten? Further, some berries are edible and therefore food, whilst others are poisonous and therefore not food. Many different people of many different ages must have slowly fleshed out which berries are edible and which ones aren't. Lastly, some foods, especially processed ones, contain ingredients that aren't necessarily food (think Tartrazinek a.k.a yellow die number 5), yet we still consume them when contained as an ingredient of a food.
Also, if water is so importent to us, why it dont taste good for us? You whould guese that our brain will make it taste good for our surviveling.
I think I get what your saying. Many people either don't like the taste of water or find that it has a neutral taste (basically no taste) and would prefer to drink juice, soda pop, milk, tea, or some other substance.
Don't forget though, that many liquid substances contain water (most juices do). Also, most foods also have water in them.
Some fruits and vegetables are almost 90% water by weight and even meats have a decent percentage of water in them. So, at first it may seem that water should taste better to a human, but I feel what it lacks in taste, it makes up for in being in almost everything we eat and drink, making it difficult not to get some amount of water every day.

Beyond the tap: Other sources of water it fits in well with what I'm saying at water
