What is the scientific explanation why people like or hate different foods to each other?

I have a theory of my own I have absolutely no way of backing of course.  \n\nCertain people can taste certain chemicals depending on their genetic build.  My theory is that some people can detect certain chemicals within certain foods and others can't due to their genetic makeup, which makes their tastebuds capable of detecting certain chemicals and not detect others, and thus make them like or dislike a particular food.  \n\nIf you can't taste the "yucky" you can't say it's terrible right?  \nThen again, some other person might be able to taste it and not like it...

People who don't like others because they are different are ignorant. People often fear what they don't understand, and ignorant people only like others like themselves because they understand and can relate to people similar to themselves, but those that are differnt because of lifestyle, race, language ect. they don't understand and there for fear. Of course they don't say that's why they dislike someone, or a group of people, but that is why. These type of people are not to be hated for their ignorance,they should be pittied, because they live sad scarred, small close minded ignorant angry life, surrounded by other sad pathetic close minded ignorant people just like them:-)

For some its their beliefs, others cultures, others religion, some people because of dietary requirements and some people because of events in society such as the treatment of animals and the additives used in foods these days.

It's psychological, sensory or learned.\n\nI am very bad for that.  I do not eat left overs because my psyche can't handle what spoilt food looks like and any notion that the food is old turn sme off even though it looks fine.\n\nOn the other hand any odd thing about food turns me off and I cannot continue to eat it.  If the meat should be pink and its a faded pink, I cannot eat it.  If it looks, smells or feels bad or odd I cannot eat it.\n\nMy husband will eat food 5 days later and that thought makes me sick.  I cannot eat rich food - creamy, expensive dark cholcolate - it i stoo rich for my senses.\n\nI do not eat pork because the woman I grew up with as a child, taught me that pork and shellfish is evil. I haven't lived with her in over 20 years and I still cannot bring myself to eat bacon or any pork or shellfish.\n\nMy son has autism and he has major sensory issues to food.  He lives on hotdog and macdonald's french fries and chocolate milk.

Many people don't like different things or things that cause change.  People are creatures of habit and, sadly, become so fixed in their habits and opinions that they don't like anything that isn't like them. \n\nIt is sad but I think it is slowly changing.

Have you ever seen a Mentos put into a soda before?  If not, the result is a mass explosion of soda.  The reason is because of a bad chemical reaction, not to mention that your tongue is divided into different parts for different tastes and while the taste of the mint is on its part and the soda blends with it, they attempt to overpower each other and result in "nastiness"

Because all people are prejudice.\n\n(that is the short answer... now i will explain)\n\nPeople learn things from birth... these things may not always be correct, ut nonetheless these lessons influence our decision making and beliefs.\nHence, everyone comes along with pre-judgements on just about everything.\n\nYou can't tell me that if i say "ice cream" you won't have an idea straight away, without researching the history of it, the social implications etc etc etc. Hence, everyone makes pre-judgements based on their own experiences and therefore everyone is prejudiced to some extent.

Chemical. Because the way everything reacts to make you taste things. Thats why different things have different tastes. A physical property would be touch cause thats how it feels and theres no reactions taking place.

Actually I mentioned this saying in an answer yesterday (how weird) and I do believe it's true.  Let's say you go to a restaurant and have the best meal you have ever had.  You go back a month later and the food is horrible.  Did your opinion of the quality of the food go up or down?\n\nHandmade objects are unique and each one will be different, but the same still applies.  If you buy a handmade item for yourself and love it and decide to buy one for a friend and it is poorly made then the vendors reputation and the the quality of their product has suffered.

i think people don't like GM food because it FEELS not safe. scientifically speaking, it's a wonderful technology that solves lots of problems in farming and in giving better quality. GM food has been tested for years and till now there isn't any scientific evidence saying there's sth wrong with it. i guess it's just that people hate it because it involves "playing" with genes.\n\nactually i live in iraq and GM food is not an issue here but i got interested and read about the subject.

One of the simpler reasons is personal choice. The majority of people prefer to associate with people that are similar to them. This is basic group dynamics. We gravitate toward people with whom we have common interests.

It depends on what you are tryng to advertise. Example: McDonal. Yellow makes people hungry and red makes people want to leave. Fast food. There have been studies done that tell what colors have effect on the human brain.

“tasty” is entirely a matter of preference. As others have said, other cultures prefer lamb, or chicken, or fish. Even within the US many people prefer seafood or pork or chicken to beef.

Ignorance and greed, in my opinion cause hatred.  I don't know where you are from, but I think most people are good at heart.  Fear is a negative thing too.  People fear what they don't understand.

Sounds like a title for a school science fair project.\n\nYour basic senses can overlap in your daily life, including when you eat.  Doesn't the food taste different when you have a stuff nose during a cold?  Haven't you ever seen someone hold their nose when eating something they didn't like?\n\nIf you think about it -- sight affects taste, too.  Would you eat a green steak or drink blue coffee?  Even if they were both of the highest quality?  Our senses overlap and cause crazy reactions to simple things sometimes...

what does skin color have to do with food preferences?

Don't offer alternatives.  However, keep in mind that some people just have aversions to some foods.  A few dislikes isn't necessarily bad, but a child who consistently rejects what is offered needs to learn to deal with their options.
