Animal Proteins – Watch Out ! : Part 1

There are a lot of great sources of protein that one can be provided of.  The best source of protein being from animal products such as bison, chicken, fish, etc.  Even better if the products are organic.  However there are other sources of protein that an individual can obtain.  These proteins are, whey and casein protein which are derived from milk, vegetable protein such as pea protein, soy protein, brown rice protein, and hemp protein.  There are also nut and cereal protein that many people think are considered proteins but are not typically categorized as protein.  These types of proteins do possess a type of protein content, whereas cereals for example contain the protein called gluten, but are not considered protein sources.

Why is there such a big hype nowadays about organic and natural animal products versus the conventional animal products in supermarkets? Is it that organic animal products are better for the human body development?  Simple answer, yes it is better for body development as it has less harmful effects to the internal body.  Organic products contain less antibiotics, hormones, and less pesticides from the soils which all enter the meats and into the body (1).  What are the effects of these additives in the meats to the human body?  Hormones are injected in animals in order for them to grow quicker and reproduce faster in order to be packaged and sold at a higher pace in order to increase profits (2).  The major concern consumers have and more aware of now, is that injected hormones can disrupt the endocrine system, or hormonal system, of the body, causing to increase incidents of certain cancers, thyroid issues, obesity problems due to increase stress or inflammation around the gut, diabetes, endometriosis, uterine fibroids, infertility, asthma and allergies (1).  A known injected hormone used on cows is recombinant bovine growth hormone (rbGH) (2).  This hormone is derived from the hormone bovine produced by the pituitary gland, which main function in cows is to produce more milk (2).  It was approved by the FDA (Food and Drug Administration) in 1993 (2).  It was discovered that the female hormone estrogen also had an effect on growth rates in cattle’s and chickens.  In the early 1950’s, diethylstilbestrol (DES), a synthetic drug, was used to mimic and increase the growth rates of these animals (2).  When humans eat hormone-injected animal products, they are also ingesting the hormones put into them.  Just the same for the same as the animals, these hormones mimic the effects of the hormones produced by the body already, initiating an increased production of the type of hormone.  At this point is where issues start to arise in the human body when hormones start to react in chaos.

Antibiotics on the other hand, have been used since the 1940’s in hopes to prevent many illnesses in humans, which in fact the industries had succeeded (3).  Although antibiotics became a major issue once farms started injecting animals in order for them to grow quicker.  Antibiotics harm the body in a different manner than hormones.  The concern that arises for many is that antibiotics cause a resistant bacteria strain in animals that carries on to humans with the same effect (1).  “According to the federal Interagency Task Force on Antimicrobial Resistance, “[t]he extensive use of antimicrobial drugs has resulted in drug resistance that threatens to reverse the medical advances of the last seventy years.” Since antibiotics have been used so widely and for so long, antibiotic resistance has become a major public health threat” (3).  This antibiotic resistant disrupts the way the human immune system can fight off any infection or be able to react to any antibiotic treatment the body undergoes.  Antibiotics may also disrupt the intestinal gut causing an imbalance or a disarray in the healthy bacteria of the gut (1).

Needless to say, to keep the body functioning optimally, it is important to keep the gut intact.  Therefore, avoiding antibiotics as much as possible will put less stress on the gut and the body, resulting in a less inflamed environment making it easier for the organs to function, muscles to move more smoothly, and better mental clarity.
