Exploring Non-pharmacological Hypertension Management: DASH, Paleolithic, and Ketogenic Diet Comparisons: A Systematic Review.
Synthesis in Current hypertension reviews, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionHypertension impacts over one-third of the global population of adults and is a significant contributor to premature mortality, despite substantial progress in pharmaceutical interventions. Increasing evidence supports dietary strategies for the prevention and supplementary management of hypertension.
methodsThis systematic review was conducted in accordance with PRISMA 2020 guidelines. Literature was retrieved from PubMed, MEDLINE, and Cochrane databases for studies published between 1995 and 2025, using the keywords: "Hypertension," "DASH Diet," "Paleolithic Diet," "Ketogenic Diet," "Low-Carbohydrate Diet," "Blood Pressure," and "Cardiovascular Risk." Two investigators independently screened all titles and abstracts to determine eligibility for inclusion in the systematic analysis.
resultsThis review examined 13 studies involving approximately 87,597 individuals to evaluate the effects of four dietary strategies, DASH, Paleolithic, low-carbohydrate, and ketogenic diets, on hypertension. The DASH diet demonstrated persistent decreases in systolic blood pressure, particularly among adults. Low-carbohydrate and ketogenic diets enhanced both blood pressure and weight in overweight persons. The Paleolithic diet, supported by the most extensive sample, demonstrated significant advantages for blood pressure and metabolic health. All diets showed potential, with the Paleolithic and DASH diets emerging as the most effective approaches for hypertension management. DISCUSSION: Non-pharmacological dietary interventions are increasingly recognized as high-impact and sustainable strategies for the management of hypertension. This review emphasizes that dietrelated strategies, most importantly the DASH and Paleolithic diets, are providing clinically significant reductions in blood pressure and cardiometabolic risk. Short-term outcomes are encouraging, but long-term safety and compliance are important concerns, especially for the ketogenic and lowcarb diets. Variation in study quality, sample size, and measures of adherence complicates direct comparisons. Personalization and integration with lifestyle are central to outcomes.
conclusionDietary interventions showed the highest potential for blood pressure prevention and control. The DASH and Paleolithic diets offer the strongest evidence to support their usage among all the therapies studied. However, further high-quality, long-term clinical studies would be needed to support these results and give evidence-based diet recommendations. Future efforts should focus on nutritional adequacy and sustained adherence to optimize outcomes in the hypertensive population.
