From Denise Minger at the person who made the study of China at the head, comes this report that the calcium as milk is leaching calcium from bones, and do not eat animal protein. Humminah-va? Like most things that make good headlines, the actual research is much more subtle nuances, and I recommend you read the entire article. Risking to get into trouble, I'm going to put it all here, but youd have to scroll down past a bunch of articles about things of cholesterol and heart health to get to the bone material, which can lead you to think that I posted the link correctly. b (And if you want
) Thank you, Betsy, what is my attention. Fascinating! b (PDF) Do-Fan Hu Xi-He Zhao Jian-Bin Jia, Banoo Parpia, T. Colin Campbell. True to its name, this article examines the role of calcium in bone density in the study of China dataBЂ "with particular emphasis on the effect of dairy calcium compared to plant calcium. Campbell et al. increased five districts of BЂњdistinct lifestyle and dietsBЂ ": dairy-meat loving Xianghuangqi, theb, as well as rural, almost-vegetarian economy of Jiexiu, Cangxi and Changle. But before we look at the very report letBЂ ™ s see how Campbell briefly its findings in AB
Cornell Chronicle to an article in 1994, animal proteins, including from dairy products may be more leaching of calcium from the bones than enters the body, said Campbell, a professor of biochemistry nutrition at Cornell and director of the Cornell-China-Oxford Project, the most comprehensive project on diet and disease ever conducted. Campbell [and other members] have analyzed the role of dietary calcium in bone density is closely following the diet 800 women from five countries with very different diets in China. BЂ | B
Analysis of these data show buy generic lasix online that increased animal protein, including protein from dairy products, BЂњalmost, of course, contributes to a significant loss of calcium in the bones while vegetable diet clearly protects against bone loss, BЂ "Campbell said. Sounds pretty clear: dairy-food districts had poor bone health because of their habit of animal protein and vegetable diet are more skeletons great. In other words, milk does a body bad! But above summary in accordance with this paper is actually found? First, the type of letBЂ ™ that women in each district, as a rule, are:
* To not get BЂњyouBЂ ™ re trying to justify your milk addictionBЂ "line and / or charges of belonging dairy industry IBЂ ™ d like to remind everyone that dairy hasnBЂ ™ t been part of my diet for six years, and I think that most people consume dairy (low fat, ultra-pasteurized, etc.) absolutely nasty stuff. But doesnBЂ ™ t mean that I wonBЂ ™ t protect the dairy, when science requires. As you can see, Xianghuangqi ate pretty shabby diet as an all-vegetarian food is concerned: WeBЂ ™ in my abundant milk, beef, mutton, wheat flour, vegetables, just a little, and millet. Their bones have to click like peanut brittle! TuoliBЂ ™ is not much better, with milk tea, meat animals, and decided lack of green leafy vegetables. A bone snappage, right? Analysis of the individual for all countries showed that the combined [bone content] and [bone mineral density] were positively correlated with total calcium (r = 0. 27-0. 38, P 0. 0001), dairy calcium (g = 0 . 34-0. 40, P 0. 0001), and to a lesser extent with nondairy calcium (r = 0. 06-0. 12. P = 0. 001-0. 100), even after age and / or body weight were adjusted for. The results strongly indicated thatb
calcium, especially dairy sources, increase bone mass
to middle-aged and older women, facilitating optimal peak bone mass at an earlier age. You noticed that? Dairy calciumBЂ "much more than plant calciumBЂ" was associated with strong bones. In addition, the report emphasizes that BЂњnondairy calcium BЂ | showed no connection with the bone variables after age and / or body weight were adjusted for. BЂ "
Comparing the results in Table 7 reveal thatb calcium from dairy sources associated with the bone variables to a greater extent than calcium from nondairy sources is likely to result in higher bioavailability of milk calcium. Comparison of bone mass of women in five countries showed that 20% would be more to bone mass in the distal radius was observed for all age groups of women in County Y. [Xianghuangqi], AB
pastoral country with a high consumption of dairy products, compared with nonpastoral areas with low calcium intake. IBЂ ™ will add their unwanted 2bў and suggest that calcium, probably wasnBЂ ™ t just a protective factor in the dairy food countries. Age of cheese, most likely consumed at least Xianghuangqi, high in vitamin K2BЂ "nutrition superstar when it comes to bone health (among others). K2 isnBЂ ™ t present in foods of plant origin, excluding fermented soybean product called natto (
). The report emphasizes dairy foods and high consumption of fat (25% daily allowance of calories, compared with 9 9. BЂ. "13 6% for other countries), potentially increasing the absorption of fat-soluble vitamins necessary for healthy bones. So how Campbell on the conclusion that research BЂњincreased level of animal proteins, including protein from dairy products, almost certainly contribute to a significant loss of bone calciumBЂ "? Dairy of an arguable matter how you rotate, but the rest of his statement is probably due as follows:
relationship between bone mass and other nutrients as food protein and phosphorus were also considered. However, none of these nutrients showed relation with bone mass as much as did calcium, althoughb
inverse correlation is observed consistently for nondairy animal protein. Unfortunately, thatBЂ ™ s just all advertising material which mentions animal protein in relation to bone mass, so we canBЂ ™ t see data BЂњconsistent inverse correlation. BЂ "In the context of this study, however, it makes sense: Protein has a complex relationship with bone formation, acting as AB, but also as a potential enemy, when calcium intake is low. In other words, the effect of protein on bone health depends on how much calcium youBЂ ™ re taking in. So, for the countries in this study ate more animal protein, but rarely calciumBЂ "such as Changle, who was Top non-dairy food consumption, and low calcium (average 230 mg easy-to-day) BЂ "I wouldnBЂ ™ t be surprised if animal protein / bone relationship was weak. Whether this trend will hold at a higher calcium intake is a different story. In any case, this conclusion doesnBЂ ™ t jive with most other studies conducted on this topic: Most studies show AB
protectiveb link between animal protein and bone density, formation and preservation. BЂњProtein animal breeding was variable theb
strong negative associations with the risk of hip fracture would be in a prospective study of women of Iowa. Proteins from plant sources, did not seem to protect against hip fractures. BЂ. " BЂњContrary expected to be
Elders of animal protein to several times the RDA also be the least bone loss after taking into account known factors. Nonanimal source of protein, not related to missile defense. These results show that the typical consumer population of proteins of animal origin within the normally consumed, does not cause bone loss. Rather
to consumption of animal protein is important in maintaining bone or minimizing bone loss in older people. BЂ.

On the other hand, the negative association between vegetable protein and BMD was observed in both sexes. BЂ | This study confirms the up

BЂњCalcium Store down as commodities AB high protein of the total food sources such as meat. BЂ "
Also, if animal protein had the bone-killer and vegetable protein bone protection, weBЂ ™ d see vegetarians or vegans who have the best results in the bone department. But this is only ainBЂ ™ t matter. At best, not the same sarcophagus combined with their colleagues omnivores, at worst theyBЂ ™ re more prone to fracture. would BЂњThe facts collected consistently confirm the hypothesis that vegetarians have lower in bone mineral density than their non-vegetarian counterparts. BЂ. " BЂњIn review of 9 cross-sectional and 1 longitudinal study, there is little statistical significance between bone density and bone content was found between vegetarians and omnivores. BЂ. " BЂњThe results show that vegetarian diets, especially vegan diet associated with lower defense, but the magnitude of association of clinically insignificant. BЂ.

So while BЂњcalcium-leechingBЂ" properties of animal proteins is a common battle cry in the vegetarian world, the study only doesnBЂ ™ t support. There are some interesting (and peer-reviewed!) Documents there, looking atb. Read that link for an amazing itBЂ ™ s. But back to our subject. This paper, with its own name CampbellBЂ ™ s it suggests strongly the bone protective role for dairy foods in the diet. Not exactly the message we have heard in the study BЂњThe China. BЂ "
So much food for thought. In some ways it is sad to me I would think avoiding certain foods is a magic bullet for my weak ankles. In other ways it makes me happy. I can enjoy my MAC-n-cheese in the world. .
