Adults who are following the DASH-style eating pattern to lower their blood pressure can expand their protein options to include lean, unprocessed pork, according to research from Purdue University.

'This study supports that the DASH diet can include lean, unprocessed red meats in the appropriate serving sizes,' said Wayne Campbell, a professor of nutrition science.

The study compared lean, unprocessed pork with chicken and fish as the predominant protein source in a DASH-style diet.

This study applies only to cuts of unprocessed lean pork, such as tenderloin and fresh, uncured ham trimmed of visible fat. Each serving size was three ounces. These findings should not be extrapolated to other pork products with higher fat and salt content, Campbell said.

A comprehensive study of a major California estuary has documented the links between nutrient runoff from coastal land use, the health of the estuary as a nursery for young fish, and the abundance of fish in an offshore commercial fishery. The study focused on Elkhorn Slough and Monterey Bay on California's central coast. 

A new study shows that, from 1500 until 2000, about a third of floods in southwestern Netherlands were deliberately caused by humans during wartimes. Some of these inundations resulted in significant changes to the landscape, being as damaging as floods caused by heavy rainfall or storm surges. 

This month marks the 10-year anniversary of the first successful total marrow irradiation (TMI) using the TomoTherapy System, first performed at City of Hope in Duarte, California. Since then, numerous centers around the world have adopted the approach, once considered to be impossible because of limitations inherent to conventional radiation therapy systems.

TMI is an advanced form of total body irradiation, which has traditionally been an important part of bone marrow transplants (BMT). People with certain types of cancers or other diseases including leukemias, lymphomas and multiple myeloma may undergo a BMT as part of their treatment. Before the transplant, chemotherapy and/or radiation may be given to neutralize any cancer in the marrow.

Nutritionists take a lot of criticism - conferences that revolve around Yogic flying instructors and actresses who think their breast milk has "otherworldly power" will do that to your field, but there is at least one way to know if someone knows what they are talking about - multidisciplinary health care professionals who hold the Certified Nutrition Support Credential (CNSC) scored significantly higher on a survey about their approaches to nutrition support practice than those who do not hold the credential according to new study. Multidisciplinary may be more important than the CSNC, if it means actual knowledge of biology and medicine.

Europe's most homophobic countries may be paving the way for a rise in HIV cases among gay and bisexual men, according to new research published in the journal AIDS.

An international team of researchers from Europe and the US looked at HIV-related service use, need and behaviours among 175,000 gay or bisexual men living in 38 European countries with differing levels of national homophobia.

They found that men in homophobic countries had fewer sexual partners and were less likely to be diagnosed with HIV. However, they also found those men knew less about HIV, were less likely to use condoms and are at greater potential risk of getting HIV when they do have sex.
