If you listen to the US Cattlemen’s Association, they will tell you there is no difference between factory farmed, grain-fed cows and grass-fed cows. They will point to this study and that study to prove their point. I think most people inherently know that isn’t true.
I recently came across a study that summarizes all studies done on grass-fed vs. grain-fed beef and they came to a very different conclusion. Their conclusion is that grass-fed beef is healthier for us in many ways. Watch the video below for the details.
If you look other places online, you will find that most health experts recommend that people eat fish. They are loaded with nutrients that are beneficial for a lot of things. In particular, they have omega-3 fatty acids in them.
Omega-3 fatty acids are a class of fats that are essential for human beings. When I say essential it means that they must be obtained from diet. We cannot synthesize them from other fats that already exist in our body. They have been shown to have many heath benefits to them. Some are listed below.
- Reduce varicose veins
- Reduce blood pressure
- Reduce blood triglycerides
- Reduce heart attack rates
- Improve cholesterol levels
- Reduce cardiac arrhythmias
- Reduce depression
- Reduce the risk of stroke
- Protect you from cancer
- Reduce symptoms of rheumatoid arthritis
- Reduce the risk of dementia
- Increased immunity
All of these health benefits have been documented by studies. I routinely recommend that my patients eat fish and take fish oil supplements. If that’s the case, then how in the world could eating fish be bad for you?
The problem with eating any old fish is that many fish we consume are farmed. Farmed fish are grown in large tanks and fed diets full of grain designed to fatten them up very quickly. When fish are fed grain, they consume large amounts of another fatty acid. This fatty acid is called omega-6. While this fatty acid is also essential, in large amounts it can be dangerous. It is the precursor of all of the inflammatory enzymes in the body. Farm raised fish, therefore are actually pro-inflammatory! (For the dangers of inflammation see one of our earlier posts.) Inflammation is behind many human diseases including heart disease and cancer.
What you must do is eat wild fish. When you buy fish from the meat counter at your grocery store, they always delineate what fish are farmed and what are wild. Always buy wild fish. These fish are the ones that will have all of the protective benefits for your health that you are looking for. The farmed fish may actually be detrimental to your overall health in the long run. Any fish that you buy in the freezer section is almost always going to be farmed as well. Always buy fresh fish and always buy wild.
