Research on Blue Zones suggests that a low-protein, plant-based diet may support longevity and reduce disease risk. But does this mean a high-protein diet is unhealthy? Here’s what the science says.
The flip side of may, is may not. It’s difficult to draw lifestyle decisions from a observational study using FFQs, amongst a population with elevated insulin levels. Protein+insulin is probably not a great combination for all situations. Metabolic context is extremely important when discussing lifestyle interventions
Adding to the confusion, some doctors and scientists believe protein restriction is a key to longevity, and therefore we should aim for less protein than even the RDA suggests. The general concern is that protein promotes growth, and as we age we need to prevent abnormal growth, such as cancer cells or amyloid plaques in the brain.
While there is preliminary evidence in worms, rodents and other animals that protein restriction can promote longevity, data in humans are lacking. 22
Therefore, we feel it is premature to draw any conclusions about the potential risks of consuming too much protein on a low-carb diet, especially given the clear risks of eating too little protein (frailty, sarcopenia, etc.).
