Awesome! I’ve looked forward to the protein chapter since the beginning of the semester.
Protein is quite possibly THE most important, yet most misunderstood macronutrient in human history. It is the building block of all sustainable life on this planet, the amino acids it provides absolutely critical to functions in our body. It’s worshiped by body builders, strength athletes, and the recreational gym rats. It’s been the main form of sustenance since the dawn of time to all cultures.
Protein is critical to gaining, maintaining, and losing weight. The latter being the first topic of discussion for this post.
1) What are the pros and cons of a high-protein diet like the Adkins diet?
If I may, I’d like to just brush on the history of the Low-carb diet. For those of you who think this is a fairly new thing, you’d be surprised to know that it is nothing new.
Once upon a time, I believe it was 1862, there lived a man named William Banting. At the ripe old age of sixty-six, was a stoutly five foot five and well over two hundred pounds. William never considered himself to be lazy or overly indulgent at the table. After his thirties he began to pack on the pounds, despite any effort he put to keeping it at bay. He began exercising and gained new muscular vigor and as most will attest to after working out, a prodigious appetite, and yet continued in the weight gain. He constricted his caloric intake which, again like most, did not move the scale and left him tired and weak. He tried everything and yet no decrease in weight, exactly the opposite.
Banting went to the best doctors of his day, tried purgatives and diuretics and yet the weight increased. Finally he found a surgeon named William Harvey, who had heard a lecture on diabetes in Paris. See, in our bodies, the liver secretes glucose, the substance of sugar and starch. In diabetes this glucose collects excessively in the bloodstream. Harvey created a dietary regimen based on this discovery. Knowing that saccharine and farinaceous diet is used to fatten certain animals, Harvey believed that diabetes contributed to obesity, and that cutting out starches and sugars he could reverse this effect.
Harvey, then using Banting as his guinea pig, began his – what we would now call “low-carb” diet – on Banting. Banting avoided bread, milk, beer, sweets and potatoes. He dropped fifty pounds by early 1864. All other bodily ailments have seemingly disappeared from him and he was a new man.
As you can see, this particular style diet has been around for over a century. It was only after the notorious Robert Coleman Atkins, MD broke into popular fitness culture with his “Atkins Diet”. Now some refute and others praise the low carb diet for many reasons.

The pros of a low carb diet are many and I will discuss just a few that I feel are very important and yet largely overlooked by the general population.
-Our bodies were evolutionarily tuned for low carb dieting. Look back thousands of years and take a look at our ancestor’s dinner plates. Chances are you’ll find copious amounts of protein and fats. Yes there were
carbohydrates there, but I can guarantee you won’t find any refinement here. Save for maybe white rice in Asia and potatoes in Europe, you won’t find anything that wasn’t created by nature. Sugar of all things, was consumed in its raw form, either from cane or sugar beets. You won’t find any High Fructose Corn Syrup or artificial sweeteners. Just what Mother Nature gave to them and what they can harvest to provide to their families.
-A few studies have shown that increasing protein while decreasing carbohydrate consumption actually LOWERS LDL cholesterol and triglyceride concentration with a raise in HDL cholesterol concentrations. Oh, no! Lookout saturated fat intake has been shown to do the exact opposite! Prove it to me. Show me some good solid proof of a study done on humans that can prove increased saturated fat intake can be detrimental to cardiovascular health.
-There is a term many people aren’t aware of but should be: Thermic Effect of Feeding. What this means is, all macronutrients need metabolic processing to be digested, absorbed and ultimately stored. To simplify it even more, when you eat a certain food it requires a certain amount of energy to break it down and be used, energy in-energy out. This lead to the theory that a stalk of celery had negative calories. See some believed since it’s low kcal count, it would actually require more kcal to break it down in the body than the actual kcal the food contained.

Why Haven't You Read This Yet?
These are just a few of the pros, if I continued on this would become more of an article in a nutrition journal than a simple chapter assignment.
A few cons of Low-Carb dieting are as follows:
-Ever heard of the Glycemic Index? If any of you have seen a Nutri-Sy
stem commercial I’m sure you have. However, most people greatly misuse and misunderstand this potentially easy to use system. For a solid description check out http://www.fatfreekitchen.com/diabetes/glycemic-index.html. Glycemic Index can be misleading because it doesn’t take into consideration the portion size. Glycemic Load is more important. All this being said, low-carb diets restrict (sometimes to the point of obsession) a lot of otherwise healthful fruits and vegetables, due to their Glycemic index.
-This brings me to my next point. Super restrictive low carb diets do not have adequate fiber intake. First timers to low carb can suffer cramping, constipation, and bloating. Unless fiberous vegetables and selective fruits are consumed, low carb dieters could suffer chronic GI problems.
-Anyone who has done low carb and never made it past the first week, you’re not alone. It generally takes a little over a week or so for your body to completely deplete it’s glycogen stores in the muscles, and convert fats and protein into a source of energy rather than the more easily accessible carbohydrates. This leads to a significant reduction in energy as your body strains to pull every bit of glycogen from your reserves. When your body does eventually become efficient on fat and protein rather than carbs you lose a lot of water weight, which explains the sometimes significant initial drop in weight for people starting a low carb diet.
-A lot of people think that low carb, also means low fat. Nonsense, if you go low carb, up the fat as you increase your protein intake. Without the addition to fat with the high protein and lowered carbs, you will have a hard time controlling your hunger and your eventual binge on sugary sweets.

2) Is irradiation a safe process? Discuss the benefits and possible risks of irradiated foods?
Although more is to be found about the irradiation process of foods, it should be noted that like everything else in this world, it is not a cure all solution to all our food issues. It can be beneficial in the fact that yes, it kills off microbes, but consider that piece of meat. It’s still riddled with hormones and antibiotics, minus the e-coli. I think the benefits and risks can be measured out evenly when it comes to irradiation, certainly it has prevented many possible food borne illnesses since its advent, but it doesn’t destroy everything. Proper food preparation and handling is the ultimate practice to ensure that your food is most likely to just give you heartburn rather than a life altering illness.
I really enjoyed reading this post, keep up posting such interesting stuff!
