A Harvard School of Public Health study looked at the risk of heart disease and diabetes for people who ate processed and unprocessed meat.
…processed meat, such as bacon, sausage or processed deli meats, was associated with a 42% higher risk of heart disease and a 19% higher risk of type 2 diabetes. In contrast, the researchers did not find any higher risk of heart disease or diabetes among individuals eating unprocessed red meat, such as from beef, pork, or lamb.
This study addresses a criticism that I’ve had of many studies looking at the health effects of eating meat – they typically categorise red and processed meat together. Why would you assume that a diet that includes grass fed beef is the same as one that has nitrate and salt filled processed meat. It would be like putting fresh vegetables and fried chips together – they’re both vegetables right?
