Bryan Johnson highlights LDL reduction and vascular-event evidence

On 26 August 2026, Bryan Johnson highlighted LDL cholesterol as an actionable blood measure. He cited a meta-analysis of 49 randomized trials involving 312,175 people and stated that each 39 mg/dL (1 mmol/L) LDL reduction was associated with about 23% fewer major vascular events, including heart attacks, strokes, and cardiovascular death. He then stated that a combination of viscous fiber, nuts, plant protein, and plant sterols can reduce LDL by 13–14% over 6 months, and that medication can also play a role. The post does not provide a detailed dietary protocol, trial names, participant characteristics, confidence intervals, or a personal before-and-after result. The cited JAMA meta-analysis supports the relationship between LDL lowering and vascular events across several interventions, but it does not show that Johnson’s proposed food combination produces the same event reduction. A commenter identified missing stratification for physical activity, triglyceride-to-HDL ratio, concurrent medication, smoking, and alcohol. That comment is incomplete on the page and is not an independent analysis. This item is an evidence summary and biomarker-position post, not a new self-experiment. The 312,175 figure is the meta-analysis population, not Johnson’s N.

Nutrition can lower LDL 13–14% over 6 months with viscous fiber, nuts, plant protein, and plant sterols. Medications can also serve a role.
