Harvard (US) researchers find that processed meats, such as hot dogs, bacon, sausage and deli meats, increase the risks of heart disease and diabetes.
From a review of data resulting from 20 studies that involved over 1.2 million study subjects, Renata Micha, from Harvard School of Public Health (Massachusetts, USA), found an association between "processed meat," that is -- meat preserved by smoking, curing, salting, or chemical preservatives, and heart disease. The meta-analysis revealed that people who ate processed meats, such as hot dogs, bacon, sausage and deli meats, significantly increased their chances of developing heart disease or diabetes. For every 50-gram (1.8-ounce) serving of processed meat, the risk for heart disease rose 42% and the risk for diabetes increased 19%.
