As you may have heard, University of Southern California researchers recently published a report in the journal Cell Metabolism in which they related consumption of higher levels of protein from animal sources to increased mortality risk, as well as increased risk for the development of cancer. Interestingly, the same report also revealed that lower levels of protein consumption in elderly people might actually be worse in terms of risk for various health issues. The authors concluded:
These results suggest that low protein intake during middle age followed by moderate to high protein consumption in old adults may optimize healthspan and longevity.
The study followed 6,381 adults over an 18 year period and collected data revealing what foods were consumed as well as any specific health issues that developed.
Overall, I think the study does provide some very valuable information. If we are to interpret the results with the hope of gaining ideas about our food choices it’s important to recognize that the study clearly points a finger at the consumption of meat and dairy products in America, and that’s where we need to focus our attention.
