Taste is mostly smell actually, something like 80% of what you taste is from your nose.... so if you lose your sense of smell you stop being able to taste your food. Some people have an excellent sense of smell which would mean also have a more acute sense of taste as well.
And I don't think we do have the same taste buds on our tongues. It's possible to have more or fewer so enhancing different tastes. Plus we all react differently to different chemicals in the food, so some people can taste a nasty chemical in sprouts so they hate them but others can't taste this so they like them. And then there are psychological aspects - what you are used to from childhood, what your mother ate whilst she was pregnant with you, if you are made ill by some foods (I feel sick if I just smell milk, as I'm lactose intolerant and associate the smell with being sick)..... so many reasons for liking and disliking different tastes!
Maybe because we don't all have the same taste buds.
Some people like one smell, others like another.
Some like one drink, some hate the same one.
Our taste buds are different, as we are. We have around 10,000 of them in our mouth's...
Some people can't taste much, some are normal, and some can taste a great dea.
