Reducing carbohydrate intake lowers blood pressure in individuals with hypertension.

What the research says

4 studies

  1. Study: Low carbohydrate diet and effects on weight, lipids and blood pressure: A systematic review and meta-analysis of randomized controlled trials

    The study looked at low-carb diets and found that people on them had slightly lower blood pressure over time, which supports the idea that eating fewer carbs can help lower blood pressure.

  2. Study: The Effects of Different Degrees of Carbohydrate Restriction and Carbohydrate Replacement on Cardiometabolic Risk Markers in Humans—A Systematic Review and Meta-Analysis

    The study looked at low-carb diets and found they helped lower blood pressure, which supports the idea that eating fewer carbs can reduce blood pressure.

  3. Study: mHealth low carbohydrate dietary intervention ameliorates glycaemic profile, blood pressure and weight status in people with type 2 diabetes

    The study found that people with type 2 diabetes who ate fewer carbs had lower blood pressure after 3 months, which supports the idea that cutting carbs can help reduce blood pressure.

  4. Study: Low‐carbohydrate diet score is associated with improved blood pressure and cardio‐metabolic risk factors among obese adults

    The study looked at people eating fewer carbs and found they had lower blood pressure, especially the bottom number. This supports the idea that cutting carbs can help lower blood pressure.
