Disgusting animal conditions
Weird ingredients

I'm sorry, what is in my food? some fast food's chicken nuggets contain a chemical preservative called tertiary butylhydroquinone, which is derived from a petroleum. Yep, the stuff you put into your car. That's not all, either. Some chicken products are mechanically separated, which means those scraps that would normally go to waste are ending up in your nuggets. you'd be shocked to see how many of them are chemical preservatives, artificial coloring, monosodium glutamate and more.
Low food quality

It doesn't take an expert to see that most fast food chains don't use the highest quality of ingredients. You can tell by the rubbery patty, the wilted lettuce leaves and the extra-chewy chicken. They use the cheapest parts to make the products so when you're eating your hamburger you have no darn clue what part of the cow it came from, and, heck, if it's even cow you're eating! Here's an idea, spend the extra few bucks and make your own burger from meat you bought yourself.
Food safety
Food preparation
[or lack of]
It's called fast food for a reason, friends. Most of the meals you get aren't cooked with thought or love; they actually aren't even cooked on a stove. Many are unwrapped from their frozen containers and thrown into a dirty microwave. This saves the managers the time and money it would take to teach the cooks how to prepare the food properly and not worry about cross contamination. It saves their butts but doesn't make yours look any prettier.
Trans fats

You haven't heard that word in a while, probably because it was banned from a few restaurants. Why? It can raise your LDL cholesterol, or bad cholesterol, leading to a heart attack or cardiac arrest. However, not all fast food restaurants are required to list trans fat content on menus, so it's possible the food you're eating may still have it, and lots of it. Fast food items particularly high in trans fats include French fries, fried fish filet sandwiches and fried chicken, for example.

Slime

Now, you've heard all about the pink slime, and, thankfully, it's not something many of the restaurants use anymore to preserve their meats. But, that's not the only slime you may find at these fast food joints. In fact, a few fast food restaurants in Wrigley Field were shut down because they had black slime on their ice machines! Before you take a slurp of that diet Coke, make sure you aren't drinking bacteria-infested slime instead.
Environmental hazards
High fat, low nutritional value
Obesity

Fast food isn't the cause of obesity, certainly not, but it's not helping our nation fight it either. In fact, a study published by CBS News found that children who regularly eat fast food gain up to 6 pounds more a year than those who don't. With the obestiy rate so high and only growing (more than 15 percent of American children are obese), those 6 pounds are quickly adding up. Luckily, due to many lawsuits, many fast food restaurants are required to offer apple slices and milk with their kids meals.
