To eat, not to eat?

I got a shock reading a forwarded mail regarding the "pork" we are consuming. This email made claims on how the pig farms rear the pigs for commercial purpose.

In the mail it mentioned that it only takes 5-6 mths to raise the piggies to 120-180 kg. In older days it takes them 1 year to raise the pig from infancy to about 120kg. What's the secret of these pig farms to expedite the piggies growth? The called this the high-tech method. Everyday they feed the pig (infant / adult) with 1.2-1.8kg of feed. Inside the feed, more than 10% are chemical catalyst to boast the growth of the piggies. Soon, the piggies are able to grow abt 600g daily. When it reaches the size of 30kg, the piggies are feed with lots of water. At this stage it is able to grow 1.2-2kg daily. And the pigs usually are not energetic and sleeping all the time. They hardly move. All they do is sleep and eat. Just imagine the harm it brings to our body when we consume these abnormal pigs.

And the saddest part of the email. It mentioned that this kind of "high tech, commercial" farming formula is commonfor other livestocks as well.

If this is true, it make senses that we should minimise/ avoid meat consumption. Yet, we also know that the vegetables and fruits are getting less nutritions compared to 50 years ago. And similary, there are a lot of these vegetables and fruits are genetically egineered for better commercial purpose. Similarity, there are claims that these foods are harmful to us. What's more about the excessive usage of fertilizers, fungicides, herbicides and pesticides? And how can we get a balance and healthy diet?

Should we eat, or not to eat?
