Women who get the majority of their protein from plant-based sources appear to stay healthier as they age.
According to a new study, they experience less heart disease, cancer, diabetes and cognitive decline.
Researchers analyzed dietary surveys filled out by more than 48,000 healthy, middle-aged women between 1984 and 2016.
They calculated their protein intake and looked at the impact of their diet on 11 chronic diseases.
The results showed participants who ate more plant-based protein were 46% more likely to be healthy into their senior years.
On the other hand, those who consumed more animal protein were 6% less likely to stay healthy.
Greater intake of plant protein was associated with lower blood pressure, less LDL cholesterol and better insulin sensitivity, while greater intake of animal protein was linked to increased insulin-like growth factor, which has been shown to promote some cancers.
Consumption of plant protein was also more closely tied to better mental health.
The lead author says these findings show, “Dietary protein intake, especially plant protein, in midlife plays an important role in the promotion of healthy aging and in maintaining positive health status at older ages.”
But he recommends women also add some fish and animal protein for their iron and vitamin B12 needs.
