Dairy Article

[Guest guest]

If some of you have access to the journal Pediatrics, is has an interesting

article on the merit of promoting dairy consumption in children. Dairy

lobbyists won't like this news.

Thanks . The abstract:

" Calcium, dairy products, and bone health in children and young

adults: a reevaluation of the evidence.

Lanou AJ, Berkow SE, Barnard ND.

Physicians Committee for Responsible Medicine, 5100 Wisconsin Ave NW,

Suite 400, Washington, DC 20016, USA. alanou@...

OBJECTIVE: Numerous nutrition policy statements recommend the

consumption of 800 to 1500 mg of calcium largely from dairy products

for osteoporosis prevention; however, the findings of epidemiologic

and prospective studies have raised questions about the efficacy of

the use of dairy products for the promotion of bone health. The

objective of this study was to review existing literature on the

effects of dairy products and total dietary calcium on bone integrity

in children and young adults to assess whether evidence supports (1)

current recommended calcium intake levels and (2) the suggestion that

dairy products are better for promoting bone integrity than other

calcium-containing food sources or supplements. METHODS: A Medline

(National Library of Medicine, Bethesda, MD) search was conducted for

studies published on the relationship between milk, dairy products,

or calcium intake and bone mineralization or fracture risk in

children and young adults (1-25 years). This search yielded 58

studies: 22 cross-sectional studies; 13 retrospective studies; 10

longitudinal prospective studies; and 13 randomized, controlled

trials. RESULTS: Eleven of the studies did not control for weight,

pubertal status, and exercise and were excluded. Ten studies were

randomized, controlled trials of supplemental calcium, 9 of which

showed modest positive benefits on bone mineralization in children

and adolescents. Of the remaining 37 studies of dairy or

unsupplemented dietary calcium intake, 27 studies found no

relationship between dairy or dietary calcium intake and measures of

bone health. In the remaining 9 reports, the effects on bone health

are small and 3 were confounded by vitamin D intake from milk

fortified with vitamin D. Therefore, in clinical, longitudinal,

retrospective, and cross-sectional studies, neither increased

consumption of dairy products, specifically, nor total dietary

calcium consumption has shown even a modestly consistent benefit for

child or young adult bone health. CONCLUSION: Scant evidence supports

nutrition guidelines focused specifically on increasing milk or other

dairy product intake for promoting child and adolescent bone

mineralization.

My opinion about all those groups is they have something to sell, and they tack on to any idea that will help sell theirs. There are docs that are nut cases also.

So I read the articles and form my own opinion, as you and I did for ALA, eg. You expressed an almost silly view of ALA, but I had one article to support it, if you recall. It's just possible we the minority are correct. There just isn't a lot of scientific proof for anything in the nutritional, world. It could be something we don't even track like vanadium that causes hypertension, eg, and we get it the same time we get sodium. We can't prove that without a lot more data.

But I do know if I poke myself in the eye and it hurts, there's a pretty good chance if I quit poking, it'll stop.

It's not necessarily the land animals, the milk, or the fish that's bad - maybe it's the waste products we feed them, like waste fish parts to chickens, turkey litter to cattle, and polluted pastures to dairy cattle.

Maybe it's not the use of vegetable oils so much as hydrogenating those oils, solely to increase shelf life.

Maybe it's not eating "sugar" so much as excess calorie intake, just because it tastes "good".

If I avoid a food group, I may be leaving out the one thing I need, that isn't even in SR17. I don't care so much about dying as caring about dying from doing something stupid. When I worked under a car, I'd have every jack in my garage under the car so if it did fall, they couldn't say I didn't take every precaution.

There are "low bidders" who get contracts to "dispose" of waste products, and sometimes they bring them out to a wilderness area to dump them. In a creek. That leads to your water supply.

That can't be cleaned with chlorine. That shows up years later as birth defects - or cancer.

Regards.

Hi Francesca:I would be interested to know people's views about the 'Physicians Committee for Responsible Medicine'. I also have a nagging impression in the back of my mind that they tend to come out with somewhat extreme views that makes it SEEM as if they may have an axe to grind. But I have no hard evidence as I have not kept track of their stuff. Just a lingering impression.I have similar feelings about the 'Center for Science in the Public Interest'. Also the 'Environmental Research Group' (or is the the Environmental Working Group?) which was making a big fuss about PCBs in farmed salmon when the amounts even they were talking about were parts per TTTrillion. And they did not respond (a classic symptom of phony 'research', imo) to my email asking for confirmatory evidence that such tiny amounts could be harmful.But I am open minded to evidence in either direction regarding these groups, and others like them. Does the stuff they put out generally get published in the kind of journals we usually prefer as sources of information?Also worth making the point, though, that just because an unconventional view is expressed does not mean that it is automatically false.
