Does eating many small snacks lower cholesterol and insulin?
The claim, precisely: increased meal frequency (lente carbohydrate) decreases LDL cholesterol
Probably a modest effect, but one tiny seven-person study drove it and later trials are mixed-to-null.
Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: Human trials (RCT / n-of-1)
How the studies fall
What the evidence shows
Spreading the nutrient load (17 snacks/day vs 3 meals) lowered LDL, apoB, insulin and C-peptide on identical diets — the conceptual root of 'lente (slow) carbohydrate'. But n=7 and later meal-frequency trials are mixed-to-null: treat the dramatic numbers as hypothesis-generating.

|---|---|---|---|---|
| Jenkins 1995 1995 · Metabolism | RCT | supports | low | replicates ~8-12% LDL/apoB drop with nibbling (SAME group, tiny n) |

| Lundin 2004 · Eur J Clin Nutr | RCT | mixed | moderate | Ileostomy crossover: meal frequency plus high-fibre rye altered glucose/insulin/lipids; fibre dominated |
| Jenkins DJ, et al. 1989 · N Engl J Med | RCT | supports | low | n=7 crossover: LDL -13.5%, apoB -15.1%, insulin -27.9% on nibbling |
