The Claim

In adults aged 65 and older, replacing 162 grams per day of minimally processed lentils with minimally processed lean pork within a nutrient-dense, plant-forward dietary pattern for 18 weeks is associated with a modest reduction in fasting insulin levels and a small increase in HDL cholesterol, though these changes did not significantly differ between diets.

In plain English

In adults aged 65 and older, swapping 162 grams of lentils per day for lean pork in a nutrient-dense, plant-focused diet for 18 weeks is linked to a modest decrease in fasting insulin and a small rise in HDL cholesterol, but the differences between the diets were not statistically significant.

See the scientific wording

In adults aged 65 and older, replacing 162 grams per day of minimally processed lentils with minimally processed lean pork within a nutrient-dense, plant-forward dietary pattern for 18 weeks is associated with a modest reduction in fasting insulin levels and a small increase in HDL cholesterol, though these changes did not significantly differ between diets, suggesting that unprocessed red meat may not impair metabolic health in this context.

Why this might work

When lean pork replaces lentils in a plant-rich diet, the body uses less insulin to manage blood sugar because the meal has fewer carbohydrates and more fat and protein. The liver then processes more fat into HDL cholesterol, which helps carry it out of the bloodstream.

  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 eating a healthy, plant-rich diet, swapping lentils for lean pork daily for 18 weeks led to slightly better blood sugar and good cholesterol levels — not worse. So, pork didn’t hurt their health in this setting.
