The Claim

In older adults aged 75 years and older, a 1% increase in animal protein intake as a percentage of total daily energy is associated with a 4% lower risk of all-cause mortality and a 7% lower risk of cardiovascular mortality over a 20-year period, after adjustment for age, sex, diet quality, physical activity, and multiple chronic conditions.

In plain English

Among people aged 75 and older, those who consume a higher proportion of animal protein relative to their total daily calories have a lower risk of dying from any cause or from cardiovascular disease over 20 years, compared to those with lower animal protein intake, after accounting for other lifestyle and health factors.

See the scientific wording

In older adults aged 75 years and older, each 1% increase in animal protein intake as a percentage of total daily energy is associated with a 4% lower risk of all-cause mortality and a 7% lower risk of cardiovascular mortality over a 20-year period, after adjusting for age, sex, diet quality, physical activity, and multiple chronic conditions, suggesting that higher animal protein intake may contribute to improved survival in this population.

Why this might work

Eating more animal protein gives the body more building blocks to maintain muscle strength and size, which keeps older people mobile and reduces stress on the heart and blood vessels, lowering the chance of death from heart problems or other causes.

  1. Study: Animal protein intake is inversely associated with mortality in older adults: the InCHIANTI study.

    In older people over 75, those who got a little more of their daily calories from meat, dairy, or fish were less likely to die from any cause or heart disease over 20 years, even when accounting for other healthy habits. The study found this link clearly.
