No Debate: Cutting Salt Lowers Strokes, Heart Attacks

April 15, 2014 12:00 pm | by The Conversation, Francesco Cappuccio | News | Comments

The debate over salt intake has filled the pages of health magazines and newspapers for years. Now, a new study suggests that a 15 percent drop in daily salt intake in England between 2003 and 2011 led to 42 percent less stroke deaths and a 40 percent drop in deaths from coronary heart disease.

New Tests May Save Pork Industry

April 15, 2014 7:00 am | by Kansas State Univ. | News | Comments
