The Claim

In adults aged 65 and older, a plant-forward diet containing 162 g/d minimally processed pork and a plant-forward diet containing 332 g/d lentils both cause significant reductions in fasting insulin and total cholesterol compared to habitual omnivorous diets.

Cause and effect
1 study reviewed
In plain English

In adults aged 65 and older, eating either 162 grams of minimally processed pork or 332 grams of lentils daily as part of a plant-forward diet lowers fasting insulin and total cholesterol levels compared to a typical omnivorous diet.

See the scientific wording

In adults aged 65 and older, both a plant-forward diet with 162 g/d minimally processed pork and one with 332 g/d lentils lead to significant reductions in fasting insulin and total cholesterol, indicating that replacing habitual omnivorous diets with either protein source improves metabolic health markers in aging populations.

Why this might work

When older adults replace their usual diet with a plant-forward diet that includes either lean pork or lentils, they eat less saturated fat and more fiber. This change reduces fat buildup in the liver and muscles, allowing insulin to work better at moving sugar from the blood into cells. As a result, blood insulin and cholesterol levels drop.

  1. Study: Effects of Minimally Processed Red Meat within a Plant-Forward Diet on Biomarkers of Physical and Cognitive Aging: A Randomized Controlled Crossover Feeding Trial

    In older adults, switching to a healthy diet that includes either lean pork or lentils lowered bad cholesterol and insulin levels — meaning both options helped improve metabolic health, just like the claim says.
