Effects of Corn Flour Consumption on Human Health across the Lifespan: A Scoping Review.
Article in The Journal of 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
Corn flour, a staple food in many regions worldwide, plays a significant role in the diet due to its versatility and broad food applications. Currently, there is no comprehensive synthesis of peer-reviewed research related to human corn flour consumption and health outcomes. This scoping review aimed to examine the current literature on the health effects of corn flour across diverse populations. Three databases (PubMed, Scopus, and CINAHL) were systematically searched in July 2024 for articles that reported on human corn flour consumption and health outcomes. Eligible studies were written in English, peer-reviewed, and compared corn flour to a grain-based or no-intervention comparator. Twenty-one studies were included, investigating a wide range of health outcomes, including metabolic markers, growth metrics in infants, and risk of chronic diseases such as type 2 diabetes, obesity, and hypercholesterolemia. Findings indicated that whole grain corn products, particularly those high in fiber-rich corn bran, were associated with favorable effects on blood lipid and glycemic profiles. Conversely, refined corn products, such as cornflakes and extruded snacks, were linked to less favorable metabolic outcomes, particularly in individuals with metabolic disorders. This review highlights the potential of corn flour to affect health depending on its processing and consumption context. Although fiber-rich forms of corn flour may offer metabolic benefits, highly processed varieties may exacerbate metabolic risks. There is a clear need for more rigorous, larger-scale studies to better understand the long-term health impacts of corn flour consumption and its role in health. TRIAL REGISTRATION NUMBER: This study was registered at Open Science Framework (https://doi.org/10.17605/OSF.IO/9B8KR).
