Two Myths about Milk * the best source of calcium, good for bones

In general, milk is considered to be a health food. Drinking more milk can help us strengthen our bones and absorb calcium that we need. The kind of concepts has been deeply rooted in people’s mind. For example, kids are always recommended to drink at least three cup of milk a day in order to grow up healthy, stronger and taller just like an upstanding tree. And adult drink lot of milk to prevent osteoporosis. But have you ever wondered about milk? Is milk really good for your bones? Is it really the best source of calcium?

Before we talk about these issues, let’s look back at the history of milk.

In the book Lait Mensonges et Propagande which written by Thierry Souccar, he mentioned a reference, according to the historian Bruno LAURIOUX, after the Neolithic Age the relations between Europe and dairy can be divided into north and south Europe. Northern Europeans are considered as barbarians who did not farm and drank beast milk also wore the pelt or animal skin. On the other hand, however, Southern Europeans are the population who work in agriculture. At that time milk is a symbol of lower classes, however, in the 20th century, milk has became one of a common diets. From then on, dairy industry began to convey a message: milk is good for bones and health to the people.

Drinking more milk≠Getting more calcium Actually there is no relation between the calcium in the diets that you eat and the amount of calcium that goes into the blood for bones and teeth. Milk contains the amount of calcium, approximately 1200mg per liter and human milk contains 300mg of calcium per liter. It is apparent that human milk contains less calcium than cow’s milk, however, breastfed babies are allowed to gain more calcium into their body. How come? This is because the calcium to phosphorus rate in milk is 2:1; it is also high in phosphorus. And in fact, the phosphorus can interfere with calcium absorption. Thus drinking more milk does not mean your body will absorb more calcium.

What kind of negative influence can milk have on our bones?

According to this diagram from the blog, Raw Body and Soul, “In countries where most dairy products are consumed, such as the U.S. and Sweden, there are most cases of osteoporosis, whereas in Asia, where these products are almost not consumed at all, suffering from osteoporosis is very rare.”, and it seems “milk, contrary to popular opinion, does not strengthen bones, but it damages them.” Besides, another research has also shown the comparison of bone density between Japanese and British women. Japanese women get proper amount of calcium through the beans, vegetables, and little fish they eat, whereas British women get calcium which more than 40% is from the dairy products. However, compared with British, less than 60% of Japanese women had femoral neck facture.

Why milk is bad for our bones?

Bone is an organ which keeps regenerating. And the kind of process is called bone remodeling. According to the website, wiseGEEk, “Bone Remodeling is a continuous process of bone resorption and formation for the purpose of maintaining normal bone mass.” The cell responses to bone formation which called osteoblast and the other cell responses to bone resorption named osteoclast. However, the osteoblast will not be supplied unlimitedly by Mesenchymal stem cell which “can differentiate into a variety of cell types.” As we get older the ability to make osteoblast will decline. Then the numbers of osteoblast will certainly decrease. And our bones will become weak eventually. In order to keep our bones healthy strong we should not to stimulate osteoblast activity. Unfortunately, protein in dairy products will excite osteoblasts and increases the numbers of it, as well as, milk itself contains a kind of calcium which can stimulate bone remodeling activity. Moreover, a factor in dairy products named IGF-1 which do influence on osteoblasts to increase bone remodeling. These are the reasons for why milk is bad for our bones. As we have already said, “contrary to general opinion and media promotion, milk is not really good for us.” So when you try to get the health benefit from milk how about think before you drink?

Milk Is Bad

...Got Milk? Go suck on your mother’s breasts! Go on, do it! This is a ridiculous order but there becomes a time where you should use your own head. From a young age we are fed our mothers milk as a way to spurt our growth. After we end our breastfeeding phase, we begin to grow up and are bombarded by parents, most doctors, schools and the media to drink milk. “ Milk does a body good”. It is common belief that milk is good for your growth and bone development. It is known as a nutritious drink filled with vitamins and a source of calcium that contribute to making you stronger. However, many may be ignoring the scientific truth that drinking milk yields quite the opposite result. Through the examination of cows, the dairy industry, and humans, milk can be presented as unhealthy and bad for you. Why drink cows’ milk? Why do we not have a glass of zebra milk for breakfast, or gorilla milk with our cereal, and why don’t we drink reindeer milk? The answer is easy. We drink cows’ milk because cows produce a large quantity of milk, and a large quantity of milk leads to a large amount of profit being made. When we drink milk, do we fail to consider the source in which it came? Cows are much different than humans as their inner workings are completely different. Many cows used for the intention of milk production are injected with bovine growth hormone, which increases the production of milk. Traces of dioxin, one of the most toxic substances in the world is sometimes found in milk.......

Critical Analysis

...5 myths about the flu: In a new survey by Consumer Reports, only 30% of respondents were "very confident" that this year's flu shot is safe. That leaves many doctors and scientists perplexed. Of all the many things to fear in the world, they say, vaccines should be at the bottom of the list. USA TODAY's Liz Szabo talked to vaccine safety experts to address some of the most common myths. Myth 1: The flu shot causes the flu. The viruses in the flu shot are dead, so they can't give people the flu, according to the Centers for Disease Control and Prevention.  Its most common side effect is soreness in the arm. FluMist nasal spray contains weakened viruses, so they don't cause severe, flu-like symptoms, either. Side effects in children can include a runny nose, wheezing and headache. So why do some people swear that they got sick right after getting a flu shot? Flu shots tend to be given at a time of year when respiratory viruses are beginning to circulate, doctors say. So it's only natural that some people will catch a respiratory bug shortly after getting a vaccine. And since it takes about two weeks after getting a vaccine for the body to develop immunity, some of those bugs could be the flu. But the vaccine itself isn't causing disease. Myth 2: The flu is just a bad cold. While some people develop worse symptoms than others, flu symptoms tend to be much more severe than — and come on much more suddenly — than a cold. Many who got H1N1 (swine flu) last year were out of......

These subcategories are: folktales, tall tales, fables, myths, epics/ballads/legends and religious stories. One subcategory that falls under Folklore is Folk tales. A folk tale is a tale or legend originating among a people or folk, especially one forming part of an oral tradition. Folk tales are often part of the oral tradition of a group and are usually told rather than read. They are passed down from one generation to the next. They may be stories that grew out of the lives and imaginations of people. Folk tales can take on the personality of the storyteller and the story can take on the characteristics of the time and place in which the story is told. The themes are universal and timeless and may contain supernatural elements, imaginative characters, focus on action, have a simple sense of justice, have happy endings and contain fundamental wisdom (Chen, 2009). There are seven types of folk tales, each with their own characteristics to set them apart from one another. Anansi the Spider: A Tale from the Ashanti by Gerald McDermott is a beast tale. It is a beautifully illustrated folk tale from the Ashanti people about a spider “dad” named Anansi. Anansi is threatened by fish and a falcon, but is saved by his sons.

Animal Suffering

When you here that cigarette smoke causes cancer in lab animals what is the first thing that comes to mind? Chances are that in each of these cases you were not thinking about how the cow suffered while it was being fattened up, ho painful the trap was that caught those mink, or the conditions those lab animals hat to endure to develop that cancer. Most people do not think about these things. However, in this paper, you will be enlightened on the pain and suffering of animals in three different industries and you will also hear from the other side of this issue. First, one of the biggest culprits of animal suffering is the animal food industry. This is an industry in which people have a tendency to block out or ignore the animal mistreatment; this is done by disassociating oneself with the direct harm and ignoring the indirect harm (Harnack 133). A good start under this example in the case of pigs. Normally, pigs are intelligent animals capable of showing affection. They have very good senses of smell, which is why pigs have been used as hunting animals (Coats 31). This normal behavior is disrupted however in the food industry. Pigs are taken to slaughter at about twenty-four weeks of age when they are approximately 220 pounds (Coats 32). Pigs are usually......

Hiv/Aids

...the infection (2014). Many people with both of these viruses cannot live a healthy life due to their weak immune system, thus leading to death. This is why this disease is one of the most life-threatening and people should become more educated about it. When people hear the word “HIV,” they automatically associate it with AIDS. What a lot of people do not realize is that you do not automatically have AIDS if you have HIVS. There are actually quite some differences between HIV and AIDS. To start off, HIV is a virus, while AIDS is a disease. According to the Merriam-Webster dictionary, a virus is “an extremely small living thing that causes a disease and that spreads from one person or animal to another,” while a disease is “an illness that affects a person” (2015). Another main difference between the two is that some of the patients show symptoms and others do not. A victim of HIV is asymptomatic, which means they show no signs of the virus. A victim of AIDS shows many signs of the disease. With that fact, victims of HIV may feel and look healthy, but a victim of AIDS may feel weak and sick (“Path”, n.d.). There are many myths to how HIV is transmitted; some are true and some are false. One false myth that people believe is true about HIV transmission is that you can get it if...

Zeus

...is considered the father of the gods and mortals by the Greeks. His roots and overall guidance have been traced back to ancient Indo-Vedic traditions. Zeus and the Vedic sky god, Dyaus, share many similar powers and stories (Smith 189). Zeus is loosely translated to “housemaster” and that is how the Greeks viewed him. The Greek creation stories of Zeus vary widely, but there is one that is generally accepted. Zeus was the youngest son of the Titans Cronus and Rhea and the brother of the deities Poseidon, Hades, Hestia, Demeter, and Hera (Cook v2 17). According to one of the ancient myths of the birth of Zeus, Cronus, fearing that he might be deposed by one of his children, swallowed them as they were born. When Zeus’ birth came to fruition, Rhea wrapped a heavy stone in swaddling clothes for Cronus to eventually swallow and concealed the infant god in Crete, where he was fed on the milk of the goat Amalthaea and nurtured by nymphs. When Zeus grew to maturity, he forced Cronus to expel the other children, who were fervent to take retribution on their father. In the war that followed, the Titans fought on the side of Cronus, but Zeus and...

Types of Advertisement Slice of life advertising: This is an advertising-copy technique where a real life problem is presented in a dramatic situation and the item being advertised becomes the solution to the problem. Clips of people from different walks of life strung together with the flow of music – random emotions, religions and relations shown together is what we can call a slice of life. For eg; the ICICI ad – “bande achhe hain”, “Hamaara” Bajaj and Hero Splendor's “sago se bhi saga hai tu” are good examples of this type of advertisement. These advertisements have shown the unity, religion and culture of India. Slice of life can be topic based, for eg – Colas and Dairy milk ads during cricket world cups showing the passion of India.

Vegetarian Diets: the More Positive Side Is Being Revealed

...popularity of vegetarianism grew in the 20th century because of the combination of nutritional, ethical, and environmental concerns (Heller). With vegetarianism gaining popularity, many people are more aware of the different forms of the diet. Vegetarian eating covers a broad territory and can run the gamut from people who avoid all animal products to people who simply refrain from eating a few select animal foods (Bauer 185). The strictest type of vegetarian is the vegan. Vegans abstain from eating or using all animal products. They withdraw from eating meat, dairy, and eggs. Vegans also prefer to not wear wool, silk, or leather. Strict vegetarians have to be especially careful when planning their diet (Bauer 185). Vegans need to be responsible about getting adequate protein, iron, calcium, vitamin D, vitamin B-12, and zinc. Protein is one of the basic building blocks of the body so it is an essential part of your diet and can influence your strength but probably not your energy. Your...

Surveys have found that while a majority of Americans do take vitamin supplements on a regular or occasional basis for reason of health concerns, there exists confusion about the actual purpose and benefits of the use of vitamins. Prevention Most people have a recognition that Vitamin C prevents scurvy, that Vitamin A is found in fish-liver oils, or that Vitamin D is found in dairy products; many people believe that Vitamin E preserves youth and prevents sterility, or that Vitamin C can present colds and cancer. Beyond this, however, there is still considerable ignorance and widespread myth. The reality behind the common practice of taking vitamin supplements is less dramatic, although vitamins do represent an important component of the necessary human diet. The word vitamin was formed from the Latin word for life, "vita," and the Greek word "amine", because 19th century scientists believed that they were formed only from amino acids.
