...being added to foods, the human race must keep in mind the fact that said things are also being added to their bodies. Exposure to these particular additives could have a large impact on humans and more importantly, their children. Perhaps we should first take a look at exactly what is in our food. Steroid hormones are chemicals that are produced naturally in the bodies of all animals, including humans. They are chemical messages that control important body functions such as growth, development and reproduction. Our bodies produce them naturally in very small amounts to maintain a delicate balance. There are six different kinds of steroid hormones that are currently approved by FDA for use in food production in the US: Estradiol, Progesterone, Testosterone, Zeranol, Trenbolone acetate, and Melengestrol acetate. Estradiol and progesterone are natural female sex hormones; testosterone is the natural male sex hormone; Zeranol, Trenbolone acetate and Melengesterol acetate are synthetic growth promoters (hormone-like chemicals that can make animals grow faster). Ingesting steroid hormones, either natural or synthetic can upset the natural balance in the body and lead to health problems. Studies have shown increased rates of cancer due to the ingestion of Estrogen’s found in our food supply, especially breast cancer (Wayne, 2009). Other studies are finding connections between steroid hormones and weight gain. This should not be surprising since increased growth that is one of the main...

...natural world, she documented how those chemicals where accumulated into our bodies. Since then, studies of human breast milk and body fat have confirmed the extent of our exposure. Human beings in such remote locations as Canada’s far northern Baffin Island now carry traces of persistent chemicals in their bodies, including notorious compounds as PCBs, DDT and dioxin. Even worse, in the womb and through breast milk, mothers pass this chemical legacy on to the next generation. “Our Stolen Future”, the scientific discovery of Theo Colborn, Dianne Dumanoski and John Peterson Myers, takes up where Carson left off and reviews a large and growing body of scientific evidence, linking synthetic chemicals to aberrant sexual development and behavioral and reproductive problems, such as low sperm counts, infertility, genital deformities, hormonally triggered human cancers, like those of breast and prostate gland, neurological disorders in children such as hyperactivity and deficits in attention. The quality of men's sperm declined steadily in the early years of the 21st century until hardly anyone could reproduce in the normal way. Meanwhile, the countryside was virtually emptied of animals as natural populations crashed. The first signs of the impending catastrophe were noted in the 1990's, but few people then believed that a cocktail of pollutants that mimic human hormones could have such profound effects. So nothing was done until it was too late. Over the last few years, an increasing...

...[pic] AQA GCSE Science A Biology Summary Notes B 1 1.1 Keeping Healthy Balanced Diet A healthy diet contains the right balance of different foods. A healthy diet contains the right amount of energy. It will provide carbohydrates for energy. It will provide fat for energy and insulation. It will provide protein for growth and repair. It will provide vitamins and minerals to help our bodies function well. It will provide fibre to ensure food moves through our digestive systems efficiently. It will provide water, which is essential for all body processes. If a diet is unbalanced a person is malnourished. This can lead to being too thin or fat and to deficiency diseases. Balancing the energy If you use more calories than you eat you will lose weight. If you use less calories than eat you will gain weight. Doing exercise uses up lots of calories. The effect of exercise on health Regular exercise keeps you healthy. It maintains a good metabolic rate. It requires energy so uses lots of calories. If they are not used up they are stored possibly as fat. Metabolic rate The rate at which chemical reactions happen in the cells of your body. One major metabolic reaction is respiration. This releases energy from the food we eat. Inherited factors affect metabolic rate: Some people inherit genes that give them a higher or lower metabolic rate than others. The higher the proportion of muscle to fat in your body, the higher you...

...and crop seeds. On their website, they come across a deeply committed humanitarian organization that provides an ecologically sustainable answer to global hunger and malnutrition. The sad reality is that Monsanto is a wolf in sheep’s clothing, and perhaps one of the most unethical corporate giants in the world today. I will argue that Monsanto is on a power trip, and that they have a hidden agenda that has nothing to do with compassion, ecology or human hunger, and everything to do with greed. In the following paragraphs, I will provide a brief history of Monsanto. Then I will examine some of the promises made in their marketing propaganda, and provide evidence that these promises are little more than blatant lies. Monsanto started out in 1901 developing a highly controversial artificial sweetener called saccharine. Monsanto eventually shifted their focus to genetically modified plants and animals. They are still a major chemical production corporation, developing and marketing Roundup and several other herbicides, Bovine Growth Hormone, and genetically modified seeds. Among the most widely recognized of their genetically modified products include corn, soy and canola. These seeds have a gene inserted that makes them resistant to Monsanto's own herbicide called Roundup. These seed crops are called Roundup Ready. The purpose of Roundup is to destroy weeds that threaten crops. Seeds that are Roundup Ready can be heavily sprayed with Roundup without killing the plant. The plants are...

However, tight glycaemic control, with its inherent risk of hypoglycaemia, is required to prevent the microvascular and macrovascular complications of the disease. While islet or pancreas transplantations offer a longer-term cure, their widespread application is not possible, primarily because of a lack of donor tissue, the burden of life-long immunosuppression, and eventual graft rejection. The rapid increase in the incidence of diabetes has promoted the search for alternative cell-based therapies. Here we review recent advances in the directed differentiation of both endocrine and non-endocrine progenitors towards an islet-like phenotype. Keywords: Endocrine, progenitor cells, islet cells, insulin production, diabetes mellitus The need for cell-based therapies for...

...Quillin, PhD, RD, CNS, author of Beating Cancer with Nutrition, and other research has shed new light on diet playing a role in the prevention and potential reversal of cancer. Nutrition and diet play a substantial role in the development and preservation of the human immune system and overall health of the human body on the cellular level. However, the correlation between diet and cancer is unclear despite research being conducted in the field of nutritional oncology. Though significant progress has been realized in the treatment of cancers through modern technological advances in medicine, prevention and mitigation of cancer lay within nutrition, more specifically a natural diet consisting of fruits and vegetables, which contain antioxidants and phytonutrients. Background Cancer is a collective term describing uninhibited cell propagation in various parts of the human body [1]. This process is called carcinogenesis (literally means “cancer creation”). Once propagated, the cancer can spread and cause death in a timely manner. Cancer occurs via mutations in the genetic code that can occur in a variety of cells in the human body. Mutations of this sort are believed to be the result of oxidative stress. In the human body oxidative stress occurs when there is a disparity between free radicals and antioxidants, thus compromising the body’s ability to cleanse itself. In fact, one of the more detrimental characteristics of oxidative stress is the production of free radicals. Finding...

...Allison M. Czapracki University of Richmond Summer Quest July 20, 2004 Cereal on the breakfast table. Corn chips as a midmorning snack. A glass of milk with lunch. What do all of these scenarios have in common? Chances are fairly high that these foods contain some sort of genetically modified ingredients. Americans’ lack of knowledge about genetically modified foods was clear when a survey was conducted by the Pew Initiative on whether they had eaten them: just 24% believe they have consumed genetically modified foods (“Pew Initiative”). In the United States, an estimated 60% of processed foods now contain genetically engineered ingredients (Fox 12). With such ubiquity of genetically modified foods, there is much to be discovered about the risks and consequences of their entrance into our food supply. How do we know we are asking the right questions regarding genetically modified foods and crops? The honest answer: we don’t! To fully understand the issue at stake, we must take a look at what questions are currently being asked by delving deeply into the realm of genetically modified foods. The typical American now eats up to 34% of calories away from home; most often in the form of fast food, which is notorious for being high in fat, calories, and sugar (Spake 1). Busy Americans often do not have time to consider the specific ingredients being used in food, and most are not even aware of how widespread genetically engineered ingredients are in society...
