Many people may not realize it, 
but much of the meat we eat contains synthetic growth hormones 
and other chemicals that may be harmful to us. 
Why would cattle owners want to use growth hormones? 
It is all about money. Ranchers today want to produce more cattle 
in a shorter period. A rancher may only have about 
14 months to get the calf from a small size, 
say 80 pounds, to a selling size (around 1,200 pounds). 
Growth hormones help the cattle put on weight to get them ready for slaughter 
in record time as well as reducing the amount of fat in the meat. 
Nitrates are a chemical compound that can also be found in meat today, 
being used to cure meat and give them a healthy color. Most notably, 
nitrates are found in hotdogs, giving them their red color. 


The Food and Drug Administration (FDA) current approves of five different types 
of hormones used in food production. Of these, testosterone and progesterone are 
produced naturally by the animals and zeranol and trenbolone acetate are synthetically made.
These hormones are approved for use only in cattle and sheep. Poultry, 
such as chickens and turkeys, and pigs do not gain much weight when given these hormones, 
so they are not given them.
