Smart Protein Choices May Lower Risks of Death

Meat is a major source of dietary protein, but researchers from Harvard School of Public Health (Massachusetts, USA) urge consumers to make smart choices to lower their risks of all-cause mortality as well as death from cardiovascular disease and cancer.  An Pan and colleagues analyzed data two large-scale studies with repeated measures of diet and up to 28 years of follow-up. Utilizing data collected on 37,698 men and 83,644 women, the team documented 23,926 deaths, including 5,910 from cardiovascular disease and 9,464 from cancer. They found that a higher intake of red meat was associated with a significantly elevated risk of total, cardiovascular disease and cancer mortality, and this association was observed for unprocessed and processed red meat, with a relatively greater risk for processed red meat.  The elevated risk of total mortality in for a one-serving-per-day increase was 12% for total red meat, 13% for unprocessed red meat and 20% for processed red meat.  However, the researchers found that replacing one serving daily of total red meat with one serving of fish lowered the death risk by 7%, poultry by 14%, nuts by 19%, legumes by 10%, low-fat dairy products by 10%, and whole grains by 14%. Extrapolating the reductions in risk of death, the study authors estimate that 9.3% of total deaths in men and 7.6%  in women could be prevented if all the participants consumed fewer than 0.5 servings per day of total red meat.

242. Work Out to Ward Off Anxiety
Anxiety often remains unrecognized or untreated among patients with a chronic illness. Researchers from the University of Georgia (Georgia, USA) analyzed the results of 40 randomized clinical trials involving nearly 3,000 patients affected by heart disease, multiple sclerosis, cancer and chronic pain from arthritis. On average, the patients who exercised regularly reported a 20% reduction in anxiety symptoms, as compared to those who did not exercise...
