Here are the key benefits of blueberries for heart disease, based on Dr. Michael Greger’s work and supporting evidence:
🫀 Evidence from Dr. Greger (NutritionFacts.org)
-
A review found that 4 out of 5 studies link higher anthocyanin (berry pigment) intake to a 12–32 % lower risk of coronary heart disease; younger people saw the greater benefit (~32 %) and extreme intake (top 10 %) showed up to 47 % reduction in heart attack risk. Just half a cup (~100 mg anthocyanins) daily is enough to make a difference, aligning with Greger’s “Daily Dozen” recommendation (NutritionFacts.org).
-
Over 20 randomized trials (1,000+ participants) found that berries, including blueberries, help:
-
Lower LDL (“bad”) cholesterol
-
Reduce blood pressure
-
Improve blood sugar control & inflammation
-
Aid in weight management (NutritionFacts.org, Verywell Health, LinkedIn).
-
-
Even blueberry tea (powdered form) has been shown to reduce cholesterol in children with familial hypercholesterolemia (NutritionFacts.org).
👍 Additional Cardiovascular Benefits
-
Reduced artery stiffness, leading to better blood flow and vascular flexibility with consistent intake over weeks (NutritionFacts.org).
-
Improved endothelial (blood vessel) function, thanks to enhanced nitric oxide metabolism (PMC, University of Utah Healthcare, PMC).
-
Lowered LDL levels and hypertension, especially in at-risk groups consuming ~1 cup daily for 6 weeks or more (News-Medical).
-
Long-term epidemiological data link regular blueberry/anthocyanin consumption with reduced cardiovascular mortality and type 2 diabetes risk (PMC).

Benefits of Blueberries for Heart Disease (by Michael Greger, M.D.)
🧠 Why It Works
Blueberries are packed with anthocyanins, powerful antioxidants and anti‑inflammatory agents that:
-
Improve blood vessel function (via nitric oxide)
-
Reduce LDL cholesterol and prevent plaque buildup
-
Lower blood pressure and reduce arterial stiffness
-
Help regulate blood sugar
-
Support weight control
✅ How to Include Them
-
Daily dose: Aim for ½ to 1 cup fresh or frozen, or equivalent in powdered form.
-
Ways to eat: Add to smoothies, porridge, yogurt, salads, or drink as tea.
-
Consistency matters: Regular intake over time yields best cardiovascular benefits.
📝 Bottom Line
Dr. Greger emphasizes blueberries as a top-tier, tasty heart-healthy food. Thanks to anthocyanins, just a handful or blueberry tea daily can significantly lower coronary heart disease and heart attack risk by 12–47 %, while also improving cholesterol, blood pressure, inflammation, and vascular function. They’re a smart, evidence-based addition to any heart-healthy diet.
