7 Reasons to choose Grass-Fed Beef

  1. CLA
  2. Carotenoids and trace nutrients.
  3. Omega 3’s
  4. More Humane
  5. Less E. coli bacteria
  6. Vitamin A and E
  7. Cancer fighting antioxidants such as glutathione (GT) and superoxide dismutase (SOD)

;

1. Conjugated linoleic acid, CLA for short, can have a powerful effect on our health. In separate studies, scientists have shown that CLA can lower an individual’s risk for cancer and arteriosclerosis (clogged arteries). It also is known to reduce body fat and delay the onset of diabetes. Due to the green plants that are rich in the linoleic acid necessary to produce to CLA, grass-fed animals generally produce two to four times as much CLA as their grain-fed counterparts.

2. Carotenoids are a group of more than 700 fat soluble nutrients that produce the colors in foods. They are responsible for the coloring in carrots, pumpkins, sweet potatoes, tomatoes, and other deep green, yellow, orange, and red fruits and vegetables. Grass-fed meat has higher levels of carotenoids, making the fat appear more yellow. Typically, the more carotenoids there are in a substance, the more nutrients it will contain. Therefore, yellow fat (like grass-fed butter) is a sign of high nutrient density.

3. It’s sad to say, but fats often get a bad reputation. The truth is however, there are good fats and bad fats. Omega-3s are really good fats. These essential fatty acids, which are imperative for human growth and development, occur in abundance in grass-fed beef. These meats are a rich source of these healthy fats due to the animals spending their lives eating the green forage plants that are naturally rich in omega-3s themselves. Simply eating their natural diet, these cattle absorb these valuable fats and then pass the nutrition on to you, the consumer. This results in beef with nearly 60% more omega-3s than beef from cows that have been raised on a grain diet.

4. From a humanitarian perspective, there is yet another advantage to grass-fed beef. It should be common knowledge that the cruelties of modern factory farming are severe. Livestock cooped up in cages barely larger than their own bodies, packed together like sardines for months on end. These animals stand knee-deep in their own manure.

5. E. Coli is a very serious health threat. In fact, you are 1,000 times more likely to die of E. Coli than mad cow disease. Since Grass-fed animals have far fewer E. Coli than grain fed animals (20,000 cells/g. vs. 6,300,000 cells/g.), you are far less likely to become infected with the bacteria if you eat grass-fed beef. Also, the few bacteria they do have are not likely to survive the natural acidity of the human digestive tract. This is due to the fact that they haven’t become acid-resistant, like the E. coli found in grain-fed beef. When you feed grain to cattle, even a small amount, it makes their digestive tracts abnormally acidic. This allows the E. coli in their system to become acclimated to this environment and therefore unaffected by our body’s natural defense system.

The problem with E. coli contamination occurs in the slaughterhouse when manure from an animal comes in contact with meat. In general, the less manure on an animal when it enters the slaughter house, the less likely the meat will become contaminated. Considering cattle who live in a feedlot stand in dirt and manure all day every day, it is difficult to remove all the fecal contamination from them. Grass-Fed animals were much easier to clean because they typically come from small herds raised in clean pastures.

6. Vitamin A is an essential nutrient. It is key to healthy vision and bone growth as well as an essential antioxidant. Since grass-fed cattle consume significantly larger amounts of beta-carotene than grain-fed cattle, their meat is a rich source of vitamin A.

Studies have shown that meats from the pastured cattle are four times higher in vitamin E than the meat from the feedlot cattle. The reason for the very high vitamin E content in the meat of grass-fed cattle is again due to the grass contain very high amounts of vitamin E. In humans, vitamin E has been linked to a lower risk of heart disease and even cancer.

7. Glutathione, being called the superman of antioxidants, is the most powerful antioxidant in the body. It works around the clock to fend off offending substances. Glutathione is a triple threat to toxins. It neutralizes free radicals, enhances the immune system and detoxifies the liver.

Studies have shown that superoxide dismutase (SOD) acts as both an antioxidant and anti-inflammatory in the body. It neutralizes the free radicals that can lead to wrinkles and precancerous cell changes.

;

These are just a few of the benefits that come with choosing grass-fed beef. Of course there are the obvious things that are left out of Grass-fed beef that also are benefits. Such as being hormone and antibiotic free.

What exactly happens when cows eat corn?

What exactly happens when cows eat corn?

Nowadays it nearly impossible to escape the new health food labels, Organic, GMO-Free, Gluten-Free, Antibiotic-Free, Natural, and now Grass-Fed. These are all important in terms of finding healthy foods at your local grocery store, but what are their meanings? For instance, why is Grass-Fed important? Grass-Fed beef in particular. In order to know why feeding cows grass is important, you need to know what the alternative is. The most common feeds given to commercial cows are grain and corn based. For the main topic of discussion, we will see what happens when cows are fed corn and why you should care.

Cows are classified as a ruminant and ruminants are not accustomed to eating high-starch foods like corn, which upsets their digestive system. Cattle create a lot of gas, which they usually expel, but when their diet is high in starch and low in roughage, it forms a layer of foamy slime in their stomach called the rumen.

This slime can trap the gas, causing the rumen to balloons out and press against the animal’s lungs. Unless you act quickly and relieve the pressure (usually by ramming a hose down the animal’s throat), the cattle will suffocate.

A corn diet can also generate acidosis. Unlike the highly acidic stomachs of humans, cattle’s stomachs are normally a neutral PH. Due to is acidic nature, corn turns their stomach unnaturally acidic. Acidotic animals tend to have diarrhea, ulcers, bloat, liver disease and a general weakening of the immune system.

Another terrible fact is that cattle cannot stay in a feed lot for more than six months, because a sustained maize diet will lead to fatal liver failure. As the acids corrode their stomach lining, bacteria enters the bloodstream and collects in the liver. Here is where the use of antibiotics comes into play. Antibiotics are given to reduce gas and prevent liver infection. However, the overuse of antibiotics in the feed lots means bacteria become resistant to them. This can be a real problem, leading to new, disease-resistant strains called super-bugs.

Crazy, right? Not only do these cows have a miserable life, but their meat is incredibly unhealthy for people to eat when they’re fed a corn-based diet.

*In my next post I’ll explain how Grass-fed meat, on the other hand, contains much more conjugated linoleic acid (CLA) and healthy saturated fats that protect from cancer, aide in fat loss, and improve brain & nervous system function. Grass-fed cows are also able to move around their pens for exercise and fresh air. They don’t have to stand around in their own excrement too. In my honest opinion, It’s worth the extra money and effort to track down local grass-fed meat. Not only is it better for your health and the cow’s, it tastes a million times better too!

Why Paleo during Pregancy is Important

Annie Murphy Paul: What we learn before we’re born

“Our health and well being throughout our lives is crucially effected by the nine months we spend in the womb.

We all know that if there is any time in a women’s life that proper nutrition is considered the most important, it is the time she spends carrying a child. This is common knowledge. We have evidence of this in our millions of books and classes regarding nutrition while pregnant. Down to the everyday prenatal multivitamin recommended by most physicians. Given the obvious importance of what you eat during pregnancy and how it can effect your child for life, it behooves you to get it right. You only get one shot. However,we now know that there is more to it than that. What you experience in life while pregnant is also translated onto your child. This can majorly effect your child’s life and his or her predispositions. The fetus is forming it’s knowledge of the outside world and it’s only means of information is that which is passed down from the mother. Fetuses take cues from the intrauterine environment and tailor their physiology accordingly. This can effect everything from the speed of the baby’s metabolism to emotional and cognitive performance. In other words, you are not only what you eat, but also what your mother eats as well.

Dallas and Mellisa Hartwig from The Whole9 had a great interview with Chris Kresser on the subject of eating Paleo while pregnant. Chris is the author of The Healthy Baby Code that I highly recommend to all women who wish to optimize their eating for the health of the child. The link is at the bottom of this page.

The Role of L-Carnitine in Fat Burning and Exercise Recovery

anatomy

Carnitine is a quaternary ammonium compound biosynthesized from the amino acids lysine and methionine. In living cells, it is required for the transport of fatty acids from the cytosol (intracellular fluid) into the mitochondria during the breakdown of lipids (fats) for the generation of metabolic energy. ( In laymen terms, it grabs the fats and carries them into the stove for fuel ) Carnitine exists in two stereoisomers: it’s biologically active form L-carnitine, ( the one we’re talking about) and the biologically inactive D-carnitine.

While most studies regarding the performance enhancing properties of L-carnitine have been centered around its role in mitochondrial β-oxidation, whereas supplementing with L-carnitine aided in fat burning.  New studies however, have investigated another mechanism by which supplementing with L-carnitine could positively impact exercise recovery. Through cardiovascular research, it has been found that L-carnitine also enhances endothelial function. (The endothelium is the thin layer of cells that lines the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. The endothelium has many important functions such as vasoconstriction and dilation, blood clotting, and acts as a filter.) The hypothesis that L-carnitine supplementation may aide in exercise recovery is centered on improving blood flow to muscle tissues and decreasing hypoxic stress and its resulting sequelae (consequences). These studies have shown a decrease in markers of purine catabolism ( a byproduct of which is uric acid),  free radical generation and muscle soreness as a result of L-carnitine supplementation. Subsequently,  after direct assessment of muscle tissue damage via magnetic resonance imaging, it has been shown that L-carnitine does have the ability to reduce tissue damage related to hypoxic stress.
