The Claim

In adults aged 65 and older, consuming 162 grams per day of minimally processed lean pork within a plant-forward dietary pattern for 8 weeks is associated with a modest increase in insulin sensitivity, as measured by the Single Point Insulin Sensitivity Estimator Index (SPISE), compared to an isocaloric diet based on lentils.

In plain English

In adults aged 65 and older, eating 162 grams of minimally processed lean pork daily within a plant-forward diet for 8 weeks is associated with a modest improvement in insulin sensitivity compared to eating an isocaloric diet based on lentils.

See the scientific wording

In adults aged 65 and older, consuming 162 grams per day of minimally processed lean pork within a plant-forward dietary pattern for 8 weeks is associated with a modest increase in insulin sensitivity, as measured by the Single Point Insulin Sensitivity Estimator Index (SPISE), compared to an isocaloric diet based on lentils, suggesting that lean red meat may support metabolic health in aging populations without compromising insulin regulation.

Why this might work

Eating lean pork in a plant-rich diet lowers saturated fat and raises fiber, which reduces fat buildup in the liver and muscles. This allows insulin to work better, so the body takes up more sugar from the blood. At the same time, insulin receptors in muscle and fat tissue become more responsive, pulling glucose into cells more efficiently.

    In older adults, eating a small amount of unprocessed pork every day as part of a healthy, plant-rich diet slightly improved how well their bodies used insulin to control blood sugar — just like eating lentils did, but with the added bonus of raising good cholesterol.
