Food additives are everywhere! Read the label on most packaged foods and drinks and you'll see a long list of them.
There are a number of reasons why manufacturers add food additives to the products they make. Here are a few:

We all have certain ideas about how our food should look.
You expect oranges to be orange.
Food companies know this. So when they pick oranges that are green and unripe, they simply add some dyes to make them look like what you want to look like.
That way you'll be more likely to buy them.
Of course what is "better" is really a matter of personal preference. Personally, I like the real thing as found in nature.
Artificial flavors exist for the sole purpose of adding something extra to the taste of food.
If you eat a lot of artificial flavors you can get used to them. You may even end up actually preferring them over natural flavors.
Thanks to chemicals, you can now make instant mashed potatoes that are even more light and fluffy than anything you could ever make at home.
This means that food can travel much longer and further than it ever has. It also means that foods can sit around for a very long time.
Have you ever wondered just how long that package of cookies sitting in your pantry has been around? It may be longer than you think. Not very appetizing, I know. I'm an unashamed advocate for homemade food. ;-)
Don't be misled by the word "improve." Most "enriched" foods have actually been stripped of their original nutrients.
The manufacturers then add a few synthetic vitamins and minerals to give it some nutritional value.
It's pretty common for the final product to have fewer nutrients than the starting product. That is hardly improving on nature.
It doesn't matter which way you look at it. Food additives do not make food better for you.
In fact, many doctors, health advocates and scientists are very concerned about the health and safety of these additives. Some of the commonly used additives come with some very serious side effects.
Here is a list of food additives and the side effects they can cause. Some of them are pretty scary. I will be adding more food additives to this list when I get a chance.
Feel free to print out this list of food additives so that you can have it handy when you go grocery shopping.
