Experts agree – America needs more vitamin D. It's one more reason to grab another glass of milk, according to new research presented at the Experimental Biology conference in Anaheim, California. Milk is the primary source of vitamin D in the American diet, supplying nearly half of all of the much-needed vitamin D.
Using the latest national data (NHANES 2003-2006) on what more than 16,000 Americans ages two and older eat, researchers investigated the contribution of each food group to the total vitamin D intake. No other food item came close to the vitamin D contribution of milk. In fact, for kids ages 2 to eighteen, milk provided nearly two-thirds of all vitamin D in the diet.
"There are few true replacements for the nutrient package you find in one glass of fat free or lowfat milk," said Dr. Keith Ayoob, a registered dietitian and pediatric nutrition expert. "Without milk in the diet, it's hard to meet a number of nutrient needs – most notably vitamin D."
Many Americans are not getting enough vitamin D, and this D-ficiency may put their health at risk. Well known for its role in keeping bones strong, vitamin D is now being hailed for so much more. Emerging science suggests vitamin D may also help protect against diabetes, hypertension, heart disease and certain cancers. It also supports a healthy immune system.
Despite a potential upside of boosting vitamin D levels, Americans of all ages still fall short of their vitamin D needs. In fact, current deficiency levels prompted the American Academy of Pediatrics to double the vitamin D recommendations for children and teens. The Academy estimates that up to half of adolescents have low vitamin D levels.
Experts recommend 400IU of vitamin D each day – the amount in four glasses of fat free or lowfat milk.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
