cow's milk can decalcified bone. Cream Cheese Snacks When I tell people that my baby has never had cow's milk and my husband and I have taken the decision not to give cow's milk , people puts the fuss and the first thing I say is to be decalcified. We usually have a cow's milk as the queen supplier of calcium, when at reality is that there are better calcium sources that provide a much more comparable to our body, this article is from The Baby Bond, one of my favorite places, visit it , is worth it. http://thebabybond.com/MilkingYourBones.html Bone density: The great fallacy of the milk.
While the National Osteoporosis Foundation tells us that we need more calcium build stronger bones, mostly from cow's milk, scientific evidence does not support this.
China University of Hong Kong conducted successive studies in the 1990 analysis of milk and calcium intake and its relationship with the growth of children. This was the ideal place and time of the investigation, since cow's milk was making its way into popular usage in the country, and the traditional diet was not high in calcium.
The first study to children from birth to age five. With 90 percent of the children studied, milk consumption, average calcium intake was 550 mg. At five years, the current level of calcium intake for each child did not correlate with bone mineral density levels. Calcium intake during the second year of life proved to be the strongest predictor of bone "toughness" at five years (breast milk provide the same or better than cow's milk or other sources) .1 In the second study, children from seven years of age received calcium supplements to their daily calcium intake to 800 mg. Over 18 months there were no increases in height or density arm or leg bone beyond the no supplement, although some improvement in bone density of the spine vertebral.2 At ages 12 to 13, calcium intake did not correlate with bone mineral content, except that the girls who consumed the higher levels of calcium had lower bone density in their brazos.3
In all these studies, the more weight and increased physical activity were strongly associated with greater bone mineral content. In adolescence, or calcium intake or physical activity influenced more on improving the density ósea.4 A British study of 14 found that young adults, their body weight in adolescence and early physical activity levels determined bone mineral density, with little effect of calcium intake.5
In a widely cited study by a British hospital, the researchers provided an additional glass of cow's milk to the diets of adolescents, comparing its growth to those who drank an average of half a cup a little more than one per day. The total calcium intake per day at baseline was 750 mg, and the extra milk group increased to 1,100 mg. The researchers reported 10 percent rate of growth increased bones to those with extra leche.6 These children also gained a little weight but not height. Reported that the extra bone density can not be validated by changes in blood markers, the enzyme that normally reflect bone growth and absorption of new bone. like growth factor insulin also was found to be higher in the extra milk.
experts wrote Several answers to this study, which had been paid by the dairy industry in the UK. One of the experts, making their own mathematics in the study, found that milk group had a slightly less average bone mineral content, total mineral content of the final lel study.7
A U.S. study about children twins were some increases in bone density in the arms and spine with calcium supplements (not milk) .8 Once puberty began, however, calcium did not provide benefits.
While the promotion of dairy products also include praise for the milk protein, so this protein may be more of a problem in osteoporosis to him that calcium may be a solution. Animal proteins of meat and dairy products cause loss of calcio.9 calcium level required in the diet depends heavily on animal protein ingeridas.10 For many of diets high in animal protein of Americans, may not be possible to consume enough calcium in the diet to offset the amount lost by the high proteinas.11 For this reason, Americans have the highest rates of osteoporosis in the world, while consumption of dairy products is also among the highest . animal protein Dubbed cause the loss of 50 percent more calcium. However, when a high intake of protein is soy, a positive calcium balance can be maintained with only 450 mg of calcium per day.12 The main concern is that bone density decreases gradually with maturity . At one point of bone loss, we use the term osteoporosis. This is a level where low trauma bone fractures are more common. Spinal fractures are a problem because they are hip and arm fractures, which are easier to measure for research purposes. The highest level of bone density at age reached adult is correlated with bone density remained in subsequent decades. What is not fully understood the magnitude of the impact of dietary factors on these events. Some studies suggest that childhood calcium intake before puberty may have a slight positive effect. While diabetes, cancer and other problems may limit the amount of milk should be given to a child, it also appears that bone protection there is no reason to promote the consumption of dairy products after infancy.
A 1987 study of 106 adult women suggested that calcium intake between 500 and 1,400 mg per day resulted in no difference in bone mineral density ósea.15
A largest Italian study found that women who consumed between 440 and 1,025 mg of calcium per day, a slightly higher number of hip fractures occurred with greater consumption of leche.16
study recent than 78,000 nurses found that women who drank more than a glass of milk a day had a 45 per chance higher percent of hip fractures compared with those who drank heavily menos.17 Those who took the same amount of calcium from nondairy sources do not see that increase or a reduction in fractures. Since the studies being conducted only on women - who suffer more osteoporosis - Harvard researchers decided to look to men. They found that those who drank three or more glasses of milk per day, compared with one or less per week, had little fewer hip fractures, but were offset by the arm a bit more fractures.18 Higher intakes of calcium food and supplements together produced an increase in fractures in general.
The rate of hip fractures in the U.S. for people of many races and ethnicities is just the reverse rates of lactose intolerance. In other words, those who avoid milk for adults have fewer fractures. non-Hispanic white women with 139 fractures per 100,000 inhabitants, Mexican-Americans are 67 per 100,000, and African-American average of 55 per 100,000.19 The indigenous peoples of southern Africa have traditionally been consumers of milk. Its use is still low, although the formula is making great strides. Those of age today without osteoporosis they have not been achieved Porla formula. Typically, South Africans consume only 200 mg of calcium daily, but the fracture rate is extremely low - less than seven per 100,000 persons per year. 20 Compare this with their U.S. counterparts exposed milk. Drinking milk (and a higher calcium intake) populations throughout the world are those with osteoporosis as an important problema.21 These rates are rising in areas where the fracture is generally low throughout the world as these regions adopt Western practices.
In Japan, as in many other non-Caucasian Milk consumption has traditionally been minimal calcium intake has been low - and hip fracture rates are low, but have grown recently, 22 as is the portion of adults who were raised on milk. While industrialization also brings a reduction in physical exercise, there is a common denominator seen much more consistent schedule and geographical regions of the problems of the bones - milk cow. While we feel our nutrition today is superior over the centuries, archaeological research has shown that bone loss after menopause Caucasus in the ages 18 and 19 was less than that seen hoy.23 is clear that high calcium intake, and certainly a high consumption of milk does not help the prevention of osteoporosis.
Dairy messages.
Why conflicts between the bulk of the research findings and recommendations of the National Osteoporosis Foundation (NOF)? Other funding comes from private donations large and small, with some governments federales.24 Another strong supporter of the NOF is Bozell Worldwide, the marketing company that created the Milk Mustache campaign huge for the dairy industry. Only two per cent of the NOF funding has gone to osteoporosis research.
Solutions
good, bad and curious.
Other common foods are excellent sources of calcium, listed in order of highest amount of calories, are the following: molasses, dark green salad, cabbage, broccoli, green beans, cucumbers, peas, soybeans, squash, most types of beans (including cocoa), kiwi, maple syrup, brown sugar, and tomatoes. In addition to this list is of course human milk. Calcium can also be added to corn tortillas and a little orange juice, apple juice, rice and soy milk. When these foods are the main source of calcium and the consumption of meat is not very high, USRDA levels may be higher than needed.
The World Health Organization indicates that 400 to 500 mg of calcium per day is appropriate for adults. The U.S. RDA for calcium is 800 mg for most people a year old or more and 1,200 mg for adolescents and pregnant women and nursing mothers. Ours is the world's highest recommendation. Beyond these rules set forth above, the U.S. National Institutes Health (NIH) has gradually raised its recommendations for calcium needs for children of six to 10 years old, 800 to 1,200 mg, 11 to 24, are pregnant or nursing women, 1,200 to 1,500 mg, and more than 65 years, 1,500 mg. They base their decisions primarily on that increasingly there are more problems osteoporosis.
"The best source of calcium is through calcium-rich foods such as dairy products," said the consensus statement Development of the Conference of the National Institutes of Health Calcio.25 Optimal intake was strengthened intake of vitamin D also is added to milk and derivatives, one vitamin that naturally occurs from exposure to sun or eating fish. No mention, however none of the other nutritional factors that are important for bone development - which are insufficient in cow's milk. At the same time, the report says that taking calcium supplements sounds very complicated. Boron, copper, magnesium, manganese, zinc, vitamin C and appropriate levels of fluoride are as important as calcium for optimal bone growth. None of these are high in cow's milk, so that none of these are advertised as being important for bones.
Phosphorus is important for bone development as well, but cow's milk has too much of this, resulting in reduced availability of calcium. This is apparently the phosphorus that is not mentioned, either. Neither mentioned that NIH Reducers in the consumption of animal protein help calcium levels. (Remember the beef industry is the other end of the dairy industry.) Deep in the text mention a few other foods naturally rich in calcium, but only in reference to vegetarians, who do not drink milk. This list is quite inaccurate and exclusive, it sounds nice, greens (collard and sardine bones). They also emphasize that lactose-intolerant, a bit of gas pain and should not prevent having at least two servings of milk a day.
As more problems are evident with the milk, and people buy less, greater than for measures to encourage the drinking of milk. Is, "at least three cups of milk every day "to" all the bodies. " The NIH, whose initial intentions are often better informed of its final conclusions, half financed by the huge 1997 study showed that nurses have more fractures when they consume more milk. To date, however, has not changed its recommendations on the consumption of milk.
At the same time, the American Dietetic Association, with support from the dairy industry, continues to publish reports as "Many Asian-American elderly consume an inadequate amount of calcium in the diet." 26 Their conclusions were based on consumption of milk and no bones. It is obvious what their solution was recommended. A recent ad shows young playing basketball outside (ie, exercise or take vitamin D), which are two great ways to build stronger bones. A carton of milk next to urging them to come in, sit down and have some milk for their bones.
I ESEARCH Dutch have come up with a new milk product designed to be better for bone health. Increased calcium content and lowered protein, phosphorus and fat content - in other words, it reduces the content of dairy products. It is not surprising that older people taking the new supplement low calcium milk calcium is lost every day is less than with regular supplements .27
Dairy Deflation
Standards promote as desirable rates Child Growth and puberty are based on a comparison of children who use bovine growth hormones (natural in all milk, and also often supplemented), early and regularly, the power struggles that are raised natural. While the same height is reached at the end, obesity more common in consumer side of dairy, 28 people with the experience of nutrition called traumatic higher with increased cancer, heart disease, diabetes and many other diseases.
heavily promoted the idea that milk builds "strong bones" refers to the prevention of osteoporosis - this is the reason for the strengthening of bones. Decades of effort to show that diets high in calcium derived mainly from dairy to develop strong bones have failed to demonstrate any such correlation. In fact, the opposite seems to be verdad.29 seems that high calcium intake before puberty, especially in early childhood, may have a slightly positive effect on bones, but this diet is not the answer. A balanced intake of all minerals in the bones, along with adequate amounts of vitamin A, C and D, is what is truly necessary. A balanced intake of minerals that can occur when stresses in the dairy diet. A high content of calcium derived from dairy products causes relative deficiencies in magnesium and other minerals from bone builders, its high content of phosphorus and animal protein reduces calcium availability. Activity physics has the greatest benefit - the body efficiently use what is available to strengthen bones when it senses the need. Human milk and vegetable sources are superior to dairy products for calcium and other nutrients in many ways. There are fewer nutritional benefits or other health benefits to give cow's milk to children in what is believed, although there are many risks.
If you pay attention to ads for health research in the news, you will notice that almost every day another finding that is made of whole grains, soy, a portion of vegetables, two fruits a day; cashews, legumes, fish, or any other food - other than milk, that is - and its connection with a lower risk of heart disease, breast cancer, stroke, diabetes or other diseases. This is because cow's milk and its derivatives now constitute a third of the diet of adults and half to two thirds of caloric intake in children, thus replacing other important so they need nutritious food in the diet. This leads to an insufficient intake of some important vitamins, various minerals, and fiber and healthy vegetable oils. Cancer-preventing antioxidants in foods are not present in the diet of milk. While a form of vitamin antioxidant is added to milk (but not all dairy products), and probably offset by the pesticide and drug residues, the supplement of vitamin A and the associated enzymes found in vegetables and other foods are needed for cancer prevention. Many more types of antioxidants found in vegetables, legumes, fruits and grains. BIBLIOGRAPHY. 1.Lead WT, et al.
