The way cows are fed can have a great effect on the nutritional composition of beef.
While cattle are now often fed with grains, the animals we eat during evolution are free to roam and eat grass.
Many studies have shown that the nutrients in beef may vary depending on what the cow eats.
The important thing is not what we eat but food we eating and eating is also a problem.
The difference between cows eating grass and cows eating cereals
Most cows have
Calves are born in the spring, feeding milk mother, then free and eat grass, bushes or any edible plants in their environment.
This lasts about 6 to 12 months. Later, "standardized" cows were placed in captive lots.
Large captive lots are called Concentrated Pet Feeding Activities common place This is one of the few things that I agree with.
There, cows are fattened quickly with cereal foods, usually made from soy or corn.
Standardized cows are given drugs and hormones to grow faster, as well as antibiotics to survive in unsanitary living conditions. They live there for several months and then are put into a factory for slaughter.
As for cows that eat grass, they can continue to live on the pasture for the rest of their lives.
Of course, this is not really simple and the various feeding activities are . The term "herbivorous" is not even clearly defined.
But in general, grass-fed cows are fed (mostly) grass, while cereal-fed cows are fed (mostly) in an unnatural mode based on corn and soybeans during the Later sections of their lives.
Summary: Most cows start life on grasslands, drinking milk and eating grass. However, standardized cattle are transferred to captive lots and fed with cereals, while grass-fed cows can continue to live on pastures.
Differences in fatty acid composition
The sentence "What you eat is you that" The same is true for cows.
What cows eat can have to the nutritional composition of meat. This is particularly obvious when it comes to fatty acid composition.
Grass-fed beef usually contains less fat than cereal beef, which means that by weight, grass-fed beef contains less calories.
But the composition of fatty acids varies widely, grass-eating beef actually scores in this :
- Monounsaturated and saturated fats: Grass fed beef has this amount similar or a bit less than cereal fed beef.
- Omega-6 polyunsaturated fat: This amount is very similar in both types of meat.
- Omega-3: This is the substance that grass-fed beef actually has a big difference, it contains 5 times more Omega-3.
- Conjugated linoleic acid (CLA): Grass fed beef contains CLA nearly double that of grain-fed beef. This fatty acid is involved in reducing body fat and some other benefits .
If you cannot afford or cannot access grass-fed beef, you should eat fatty fish once or twice a week or supplement fish oil to make up for lost Omega-3.
Summary: Grass-fed beef may contain less total fat than beef fed cereals, but contains more omega-3 and CLA fatty acids that are more healthy.
Red meat is rich in nutrients, organic types contain more
Humans have eaten meat during evolution and our bodies are well equipped to digest and absorb nutrients from meat.
Traditional hunting groups like Masai and Inuit take most of the calories from meat and maintain excellent health .
This can happen because Red meat , even standard grain beef, Very nutritious.
Regularly eating beef grains contains vitamins B12, B3 and B6. It is also rich in iron, selenium and bioavailable zinc. Meat contains some of the nutrients that people need to survive .
Meat also contains a lot the protein and other lesser known nutrients such as Creatine and Carnosine, are important for our muscles and brain.
However, grass-fed beef is even more nutritious:
- Vitamin A: Grass-fed beef contains carotenoid precursors for vitamin A, such as beta-carotene.
- Vitamin E: This is an antioxidant located in the membrane and protects them from oxidation. Beef fed grass contains more.
- Micronutrients: Beef grass also contains lots of potassium, iron, zinc, phosphorus and sodium .
Summary: Even standard-fed beef is very nutritious, but grass-fed beef contains lots of carotenoids, vitamin E and minerals like potassium, iron, zinc, phosphorus and sodium.
Is grass-eating beef worth the extra cost and inconvenience?
The important thing to remember is that even beef-based beef is still healthy.
As long as you don't overcook (can make harmful compounds), that's the one Nutritious food Should be present regularly in your diet.
Grass fed beef may be more expensive and it is worth the extra cost for some people.
Depending on where you live, it may be difficult to access grass-eating beef.
While some people may live near farmers' markets or a Pure Food store, others may need to drive long distances to get them.
There may also be subtle differences in taste. Beef grass is more lean and may have some structural differences. Some people like grass-eating cows, others eat cereals, I recommend that you try both and see which one you like.
Despite all the nutritional debates, most people begin to agree that the most important thing is "just eat real food!"
I want to go one step further. Just eat the real foods they are eat real food.
