Why it supports

This study says swapping meat and dairy for foods like beans, peas, and soy can lower bad cholesterol and reduce diabetes risk by the exact amounts claimed — so it supports the claim.

What Would Prove This

Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.

1
Randomized Controlled Trials

Whether replacing animal protein with plant protein directly reduces LDL cholesterol and improves insulin sensitivity in adults with prediabetes.

A 12-week double-blind RCT with 200 adults with elevated LDL and prediabetes, randomized to consume 2 daily servings of plant protein (soy, pea) replacing animal protein vs. continued animal protein intake, measuring fasting LDL, HbA1c, and HOMA-IR as primary endpoints.

2
Cohort Studies

Whether long-term substitution of animal protein with plant protein predicts lower incidence of type 2 diabetes and LDL changes.

A 20-year prospective cohort of 15,000 adults tracking protein source substitution (g/day) via repeated food frequency questionnaires and measuring incident type 2 diabetes and LDL levels annually.

3
Systematic Reviews & Meta-Analyses

Whether plant protein substitution consistently lowers LDL and diabetes risk across diverse populations.

A systematic review and meta-analysis of 30+ RCTs and prospective cohorts comparing plant vs. animal protein intake on LDL and diabetes incidence, using standardized outcome definitions and adjusting for confounders.

4
Case-Control Studies

Whether individuals with type 2 diabetes consumed less plant protein than matched controls.

A case-control study of 500 adults with newly diagnosed type 2 diabetes and 500 matched controls, assessing 1-year dietary recall of animal vs. plant protein intake before diagnosis.
