NPR ran and interesting report comparing corn fed to grass fed beef. There is also a video for streaming.
Link
Results:
corn fed beef - better taste and cheaper
grass fed beef - likely healthier due to the omega-3 fatty acids
Look at the comments and you will see most people ignore the point of the piece and want NPR to automatically condemn corn fed beef on environmental grounds.

UK Inquiry Clears Climate Scientists in Email Row
Skeptics will not be persuaded by any amount of information, so I suppose they will still try to read what they want into the e-mails.

Britons eating fewer veg despite 5-a-day campaign
Interesting.
Spend money on 5-a-day in the UK and people eat fewer vegetables.
Japan has copied the 3-a-day dairy campaign from the US, and dairy consumption continues to fall.
I would like to know the figures for the US campaign, also. Has such a campaign ever worked?

Humane Society of the US takes a Hit
There is an ongoing battle between animal farmers and animal welfare societies. Lots of accusations and secret video taping.
Animal welfare victories prompt farmers' PR moves - USA Today
http://www.usatoday.com/money/industries/food/2009-12-25-farm-animals_N.htm?loc=interstitialskip
Now there are reports that one of the most vocal animal welfare groups, the Humane Society of the U.S., actually gives less than 1 percent of the money it takes in to animal shelters, which is where most donors likely think their money is going. Money going to the executive pension fund is 3 times that.
Humane Society of U.S. downgraded - Dairy Herd Management
http://www.dairyherd.com/news_editorial.asp?pgID=675&ed_id=10971&news_id=27301&ts=nl1
Looks like both animal farmers and the Humane Society of the U.S. need to clean up some of their practices.

Roundup of Milk as a Sports Drink Information
A new journal article has been pre-published online, relating to milk as a sports drink and body composition.
This has been a subject of interest in the dairy industry for some time, which can be seen from the funding of some of these studies.
It does make sense. Usually chocolate low-fat milk is used, so you have water and minerals for rehydration, protein for muscle recovery and sugar (from both the chocolate and the milk lactose) for quick energy.
The argument goes that it is either better or at least just as good as popular sports drinks, and it is cheaper.

Climate change scepticism - its sources and strategies
Science in the news
The Science Show (ABC Radio National)
Saturday April, 3 2010
http://www.abc.net.au/rn/scienceshow/stories/2010/2859986.htm
podcast and transcript
As always, an excellent show. This show gives some reasoning why so many people seem to be rejecting science and scientific consensus in favor of climate change skepticism and Fox News.
The conclusion is that the same model and largely the same people who worked to discredit the science behind the dangers of smoking, acid rain and ozone are new being used to fight climate science.

audio stream and a transcript
Two food topics covered were from the American Chemical Society meeting in San Francisco.
The first is an interview with Navindra Seeram, Assistant Professor of Pharmacy, University of Rhode Island.
He talks about new antioxidants found in maple syrup. His conclusion is that maple syrup is better than other sugars.
Maybe so, but that doesn't make it a health food. I love maple syrup by the way. The research is funded by industry and the Canadian government.
The second is Frank Mitloehner, Professor, University of California, Davis.
His numbers conclude that dairy and meat does not contribute as much to climate change as other scientists have concluded, because the amount of roughage (which results in methane) in cattle feed has been overestimated.
Therefore transportation contributes more to greenhouse gasses than all agriculture (26 percent versus 5.8 percent).
Five percent of his funding comes from the agriculture industry.
The finger pointing will no doubt continue.

Dietary Calcium and Magnesium Intake and Mortality

Dietary Calcium and Magnesium Intake and Mortality: A Prospective Study of Men
http://aje.oxfordjournals.org/cgi/content/abstract/171/7/801
In this study on over 23,000 Swedish men, calcium was associated with a statistically significant lower rate of all-cause mortality, and a non-significant reduction in CVD mortality.
No relation was found between calcium and cancer, or with magnesium and any mortality measure.
The lower rate of all-cause mortality corresponds to a 25 percent lower rate of death over 10 years.
Obviously it is important to determine what exactly is happening here.

Prospective association between milk intake and adiposity in preschool-aged children
Dairy Science in the literature
J Am Diet Assoc. 2010 Apr;110(4):563-70
Prospective association between milk intake and adiposity in preschool-aged children
This study on over 800 preschool-aged children finds that not only is milk consumption not related to obesity, but whole dairy (and not reduced-fat diary) was associated with a slightly lower BMI z score.
The take away message from this any a large number of related studies is that people who avoid dairy because they think it is related to overweight are mistaken.
Overall calorie intake needs to be kept in check, but excluding dairy would only reduce important nutrient intake.
Dairy as a weight loss strategy is something less clear. It is unlikely to be very effective without other measures.

Molecular mechanisms triggered by low-calcium diets

Nutrition Research Reviews (2009), 22:163-174
Dietary Ca has been associated with lower BMI and lower colorectal cancer risk. This review discusses proposed molecular mechanisms for these effects.
This is considered dairy science because the best and most frequent source of calcium is dairy. The authors conclude by recommending doctors ensure proper dairy intake for their patients.
