Nonetheless processed meat has always been linked with increased risk of heart disease and cancer, this is probably for the first time that a research has revealed the association between unprocessed meat and diabetes.
A recent study has claimed that a 2-ounce serving a day of processed meat (hot dog, bacon, salami or bologna) can escalate the risk of diabetes by 50%, while a 4-ounce serving a day of unprocessed red meat such as hamburger, steak, pork or lamb can shoot the risk of diabetes by 20%.
For the study, a team of researchers from the Harvard School of Public Health examined dietary-intake data from more than 2,00,000 men and women in the Health Professionals Follow-Up Study and the Nurses' Health Studies and then compared the same with data corresponding to diets of 4,42,101 people from other published studies.
Published today online in the American Journal of Clinical Nutrition, the study has factored a range of factors like participants' age, weight, physical activity level, smoking, family history of diabetes and other dietary and lifestyle factors.
This study is being treated as a conclusive evidence to substantiate the underlying theory of the research.
"Clearly, processed meat is much worse than unprocessed meat for raising the risk, but unprocessed red meat is not benign", said senior author Frank Hu, a Professor of nutrition and epidemiology at the Harvard School of Public Health.
