Causal association of dietary intake habits and telomere lengths: A Mendelian randomization study.
Article in Asia Pacific journal of clinical nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectivesHealthy diets are crucial in disease prevention and balanced diets can slow te-lomere shortening. Currently, it is still unclear which dietary factors are causally related to telomere length. METHODS AND STUDY
designThe inverse variance weighted, Mendelian Randomization-Egger, weighted median, simple mode, and weighted mode methods were used. Additionally, heterogeneity, pleiotropy, MR-PRESSO and leave-one-out tests were conducted to ensure accuracy. Outcomes included granulocyte, lym-phocyte, naive T-cell, memory T-cell, B-cell, and natural killer-cell telomere lengths. Exposures included alcohol intake frequency, alcoholic drinks per week, average weekly beer plus cider intake, average weekly red wine intake, intake of beef, bread, cereal, coffee, cooked vegetable, dried fruit, fresh fruit, lamb/mutton, non-oily fish, oily fish, pork, processed meat, salad/raw vegetable, tea and water.
resultsThe positive causal relationships were found between dried fruit intake and granulocyte telomere length (OR: 4.31; 95% CI: 1.29 to 14.4; p = 0.02), lymphocyte telomere length (OR: 4.22; 95% CI: 1.21 to 14.7; p = 0.02), naive T-cell telomere length (OR: 5.49; 95% CI: 1.58 to 19.0; p = 0.01). Oily fish intake was positively associated with memory T-cell telomere length (OR: 2.55; 95% CI: 1.16 to 5.58; p = 0.02). No significant causal relationships were found between other exposures and outcomes.
conclusionsThis study found positive causal associations between telomere length and the intake of dried fruit and oily fish. No significant causal relationships were observed with other dietary factors. These findings provide insights into how specific dietary components may help maintain telomere length.
