Beef is actually not bad for you. However it can be if that's all you eat, but if you have it along with vegetables and maybe a little bit of non-refined or whole-grain grain-product, it's perfectly healthy for you.
Beef is only unhealthy if that's all you eat along with too much refined grain products. It is not unhealthy when you eat it with vegetables with a little whole-grain, or when you eat a little with a lot of vegetables, fruits and whole-grains.
No and yes, depending on what type of beef you're referring to: grass-fed vs. grain-fed, and lean beef vs. fatty beef. For one thing, grain-fed beef is far worse for your health than grass-fed beef is, and too much beef is also bad for you more than a little or just the right amount (a serving equivalent of two decks of cards) per day. Beef that has too much fat (especially the white fat from grain-fed beef, which contains saturated and trans fat, as well as that are low in Omega 3 fatty acids) is less healthier than lean beef or beef with yellow fat in it.
No it isn't. Steak is meat, which is always a necessary part of a healthy balanced omnivorean diet.
No, beef is not healthy at all.
Beef is not bad for your system in small amounts. You will also not want to eat beef that is not properly cooked.
Maybe not. It depends what made the beef "bad".
Not necessarily, browning of beef while in the freezer or fridge just means that it is not as fresh as it could be. If it has a green tinge to it you know it is now bad.
If beef taste like fish then throw it out.
Yes, it is. You should not eat bad beef because it causes potentially fatal food-borne illness.
You should use beef stock two weeks after opening.
look at the label
The exact amount of time varies on the environment it's left in, though the first signs of bad beef is an odd discoloration and a rancid smell.
Paul Mcartney
It will have a greenish tint to it. And it will be a little slimy and have a bad smell
Oprah Winfrey
Although not a perfect test, your senses are usually the most reliable instruments to tell if your beef has gone bad. Some common traits of bad beef are dull, slimy flesh and a sour smell. The beef will change from a reddish color to a brown or gray color. To tell if beef in your freezer has been there too long, you will see freezer burn starting to appear on the beef.
