Replacing 3% of calories from red meat with plant protein reduces risk of death by 12% over 26-32 yr

Replacing 3% of calories from red meat with plant protein was associated with a 12% lower risk of death over 26-32 years according to a recent analysis from researchers from Harvard University.
This is the equivalent of replacing roughly 15-20 grams of protein from red meat with plant protein for people eating a diet containing 1800-2500 calories per day.
A McDonald’s hamburger contains 12 grams of protein.
A quarter-pound hamburger contains 24 grams of protein.
A 9-ounce steak contains 70 grams of protein.
Conclusion: Replacing animal protein with plant protein was associated with lower mortality
“Replacing animal protein of various origins with plant protein was associated with lower mortality,” the authors of the paper concluded.
“High animal protein intake was positively associated with cardiovascular mortality and high plant protein intake was inversely associated with all-cause and cardiovascular mortality, especially among individuals with at least 1 [unhealthy] lifestyle risk factor [which included smoking, heavy alcohol intake, overweight or obesity, and physical inactivity].”
“Substitution of plant protein for animal protein, especially that from processed red meat, was associated with lower mortality, suggesting the importance of protein source.”
Subjects: 131,342 U.S. doctors and nurses
The study analyzed data from US health care professionals which included 131342 participants from the Nurses’ Health Study (1980 to end of follow-up on June 1, 2012) and Health Professionals Follow-up Study (1986 to end of follow-up on January 31, 2012).
Study: People consuming the most red meat were 21% more likely to die
Another study found that the one-fifth of people consuming the most red meat were 21% more likely to have died compared with the one-fifth of people consuming the least amount of red meat.
