Strategy proposed for preventing diseases of aging Researchers argue that medicine focuses too much on fighting diseases individually instead of concentrating on interventions that prevent multiple chronic diseases and extend healthy lifespan. They call for moving forward with strategies that have been shown to delay aging in animals. In addition to promoting a healthy diet and regular exercise, these strategies include manipulating molecular pathways that slow aging and promote healthy longevity.
Therapeutic bacteria prevent obesity in mice, study finds A probiotic that prevents obesity could be on the horizon. Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, investigators have discovered. Regulatory issues must be addressed before moving to human studies, but the findings suggest that it may be possible to manipulate the bacterial residents of the gut -- the gut microbiota -- to treat obesity and other chronic diseases.
High-salt diet doubles threat of cardiovascular disease in people with diabetes People with Type 2 diabetes who eat a diet high in salt face twice the risk of developing cardiovascular disease as those who consume less sodium, according to a new study. Diabetes occurs when there is too much sugar in the bloodstream. People develop Type 2 diabetes when their bodies become resistant to the hormone insulin, which carries sugar from the blood to cells.
