Grabbing as little as one glass of lowfat or fat free milk could help protect your heart, according to a new study published in the American Journal of Clinical Nutrition. Researchers found that adults who had at least one serving of lowfat milk or milk products each day had 37 percent lower odds of poor kidney function linked to heart disease compared to those who drank little or no lowfat milk.
To determine heart disease risk, researchers from several universities in the United States and Norway measured the kidney function of more than 5,000 older adults ages 45 to 84. They tracked eating patterns and tested albumin-to-creatinine ratio (ACR) – a measure that when too low, can indicate poor kidney function and an extremely high risk for cardiovascular disease, according to the American Heart Association.
Researchers found that people who reported consuming more lowfat milk and milk products had lower ACR, or healthier kidney function. In fact, lowfat milk and milk products was the only food group evaluated that on its own, was significantly linked to a reduced risk for kidney dysfunction. The study authors cited other research suggesting milk protein, vitamin D, magnesium and calcium may contribute to milk's potential heart health benefits.
An overall healthy diet, including lowfat milk and milk products, whole grains, fruits and vegetables was also associated with a benefit – 20 percent lower ACR or healthier kidney function.
The National Kidney Foundation estimates that kidney disease affects about 26 million Americans – and kidney disease is both a cause and a consequence of cardiovascular disease, the number one killer of Americans. An estimated one out of three adults is currently living with some form of cardiovascular disease.
Milk provides nine essential nutrients, including calcium, vitamin A, vitamin D, protein and potassium. The U.S. Dietary Guidelines for Americans recommend drinking three glasses of lowfat or fat free milk each day.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
