Sprague Dawley Rats
Breast cancer is an incredibly common issue for American women. Research has shown that dietary factors may have an influence on the incidence of this cancer. This study implemented a feeding protocol with female Sprague-Dawley rats (a widely used albino laboratory rat) to test the effects of two ratios of carbohydrates and their effects on the early progression of breast cancers. The researchers used N-methyl-N-nitrosourea to induce mammary tumors when the rats were at 52 days of age. After induction, the rats were assigned to either a low protein/high carbohydrate diet or a high protein/moderate carbohydrate diet for 10 weeks. The rats ate 3 meals a day to closely simulate human absorption and metabolism patterns.

    In Defence Of Food Pollan Summary

    Nutritionism is the idea that the nutritional value of a food is the sum of all its individual nutrients, vitamins and other components. This is also known as scientific reductionism, when nutritionists and food scientists began to isolate the health components of food rather than the whole food product. Therefore, the food is divided into invisible nutrients and each nutrient within the food is divided into the healthy and unhealthy ones. Since nutrients are invisible, it is now necessary to rely on nutrition experts to make food choices for us and tell us which nutrients are healthy or unhealthy. Moreover, it also means that the only point of eating is to promote bodily health, which nutrients are “good” for health and which ones are “bad”.…

    Forks Over Knives: The Cause Of Chronic Disease

    This is clearly demonstrated in the scene where the rats were exposed to a carcinogen called aflatoxin and later on feeding on a diet of casein, the main protein found in milk. Half of the rats were fed 20% casein while the rest were fed 5% casein. After few weeks of experiments, the rats fed 20% casein had a greatly enhanced level of early liver cancer or tumor growth while the rats fed 5% casein had no evidence of cancer whatsoever. The significance of this experiment was to show the effects of animal protein in our body. Another significant moment is when lee Fulkerson goes on and talks about how the fast food industry was exploding and more overscheduled Americans were using it as a convenient way to feed themselves and their families (Forks over Knives). Fulkerson affirms that, “As fast foods was sweeping the nation, the rate of cancer deaths was continuing to rise [and] as a result, in 1971, the president Nixon initiated a program that was dubbed “The war on cancer” (Forks over Knives). .” The significance of this quote was that the rise of fast food companies increased the rate of the cancer in…

    Time Period in Snow Falling on Cedars and the Book Thief

    The word prejudice has been used too many times in the history of our country. Throughout wars, as well as immigrants entering the country, that word has been tossed around like it means nothing, but to those who have been persecuted against, it means a lot. The Japanese-Americans and the Jews both have had their fair share of persecution mostly leading back to the Second World War. In Snow Falling on Cedars and The Book Thief the war caused an economic downturn as well as an increased effect of prejudice on the relationships between characters.…

    The next step to understanding the microenvironment’s effects, is to understand what can affect the microenvironment, either directly or indirectly. Research into the gut microbiota, which is found in most multicellular organisms, has shown to be a significant effector on the host; whereas both overgrowth of microbes and the lack of can be associated with digestive disorders, obesity, and cancer 1.

    Phyoestrogens

    There are many positive benefits with a phytoestrogen-rich diet, especially one rich in legumes, fruit and other fibers ("Phytoestrogens: pros and," 2000). With the negatives, doctors are concerned that women who have had hormonally dependent cancers - breast, ovarian, uterine - may be causing more problems than they solve with diets rich in phytoestrogens, since they act similar to estrogen naturally produced in the body - but are much weaker ("Phytoestrogens: pros and," 2000). Furthermore, there is not enough evidence that supports that phytoestrogens are the correct supplement to take instead of estrogen for specific health conditions such as osteoporosis, heart disease or high cholesterol.…
