Some health advocates say vegetarian is the best diet. And while there are some good things about a vegetarian diet, I agree with Jordan Rubin that a diet including meat is the healthiest kind. Of course, it's very important what kind of meat you choose to eat.
Meats to Avoid -
Pork - There's a reason why God listed pork as "unclean" meat in the Bible. Biology clearly explains why pork meat is so unhealthy for human consumption.
Briefly - God created pigs as scavengers, thus they will eat anything. Because of the way they're made, they don't detoxify well, so their meat is full of all the toxins they've ingested, as well as many different kinds of parasites and viruses (including some that are extremely dangers to humans).
There is no such thing as "organic" pork. It's all contaminated, not to mention that most pork products also have added preservatives, chemicals, and toxins, along with all the antibiotics, hormones, etc. that the pigs have been fed.
If I haven't convinced you to avoid pork yet, please read these two articles containing all the gruesome details about pigs and pork meat.
Fish - In Jesus' day fish was a staple in people's diet. And ideally, fish is healthy as it contains omega 3's (healthy fat) that the body needs. However, as this article explains, because of the increasing toxicity of the ocean, fish is no longer a healthy choice. Mercury contamination in fish has increased substantially in recent years. And mercury toxicity causes many health problems, including damaging your central nervous system.
With these facts in mind, it's best to avoid fish, since there's no way to control the level of toxins in fish whether farm-raised or wild-caught.
If you're concerned about how to get enough omega-3 fats without fish, check out this article which explains how flax seeds can supply necessary omega-3's.
Processed Meats - The facts are clear on processed meats, such as hot dogs, pepperoni, sausage, lunch meats, etc. They are full of unhealthy chemical additives which significantly increase your risk of several different cancers as well as heart disease and diabetes.
One study about hot dogs linked hot dog consumption in children to a greater risk of the child developing leukemia. That's pretty scary. And completely avoidable.
Non-organic meats - One reason meat gets a bad rap is not because "meat" is bad, but because of what's in the meat.
Non-organic meats contain antibiotics, hormones, pesticides, and many times drug-resistant bacteria. Not to mention things like "pink slime" and "meat glue," both very nasty.
This is why it's so important that if you can't afford to buy all your food organic, at least buy organic meat.
Some healthy meats to consume are -
Organic, grass-fed beef - I buy Laura's Lean Beef. It's more expensive than non-organic, but totally worth it! It's healthy and tastes great. =)
Organic, grass-fed lamb - If you have a local ranch in your area, that's often a good source of organic lamb and beef.
Organic chicken & turkey - It's a little harder to find "organic" chicken or turkey, so if you can't find any, at least look for products that are free-range, antibiotic free, and all natural. (Generally speaking I also avoid ground turkey...whole turkeys or turkey breast is better.)
Organic, free range eggs - Eggs are a wonderfully healthy food that God created. But if they're not organic, they'll be full of chemicals and toxins, not to mention other nasty things that contaminate eggs produced by "conventional" egg factories.
I'm thankful that in spite of all the chemicals and toxins in the world today, there are companies working to produce healthy food. Let's do our part to consume foods that will help, not harm, our bodies.
