Encouraging direction, but not yet definitive.
This study uses a C. elegans glucose-induced metabolic dysfunction model to compare bioactive effects of two apple cultivars, finding that the autochthonous 'Amarilla de Octubre' cultivar significantly reduces lipid accumulation and oxidative stress markers whereas the commercial 'Pinova' cultivar does not. While the biological effects are clear in the model organism, translation to human metabolic disease remains undemonstrated and generalizability to dietary intake is unknown.
Controlled experimental study in C. elegans model. Caenorhabditis elegans (strain not specified) in a glucose-induced metabolic dysfunction model. Intervention: Pulp extract from 'Amarilla de Octubre' apple cultivar (autochthonous Spanish variety). Compared with: Pulp extract from 'Pinova' apple cultivar (commercial variety) and implicitly non-treated or vehicle control.
'Amarilla de Octubre' extract significantly reduced lipid accumulation by up to 23.24% 'Amarilla de Octubre' attenuated ROS production to levels comparable to non-stressed controls 'Amarilla de Octubre' decreased glucose-induced hyperphagia and preserved locomotor function

This work suggests potential value in preserving agrobiodiversity of apple cultivars for functional food applications, but the findings are confined to a non-mammalian model and do not yet support clinical recommendations. Human intervention trials would be required to assess whether increased (poly)phenolic content in traditional cultivars translates to metabolic benefits.
A sound in vivo model study demonstrating clear biological effects of a natural extract on metabolic markers, but limited to a non-mammalian organism and surrogate endpoints with no human data.

The overconsumption of high-caloric diets is a primary driver of obesity and type 2 diabetes, conditions associated with oxidative stress, dyslipidaemia, and systemic metabolic dysfunction. Apples ( Malus domestica Borkh.) are among the most widely consumed fruits globally and represent a significant dietary source of (poly)phenolic compounds with recognised health-promoting properties. However, commercial cultivar selection has substantially reduced the phytochemical richness of apple varieties available in food chains, potentially limiting their functional food value. In this study, we compared the bioactive potential of pulp extracts from an autochthonous Spanish cultivar, ‘Amarilla de Octubre’, and a commercially selected, ‘Pinova’, using a Caenorhabditis elegans model of glucose-induced metabolic dysfunction. Lipid accumulation, reactive oxygen species (ROS) production, bacterial intake, and health span-related markers were evaluated. ‘Amarilla de Octubre’ extract significantly reduced lipid accumulation by up to 23.24%, attenuated ROS production to levels comparable to non-stressed controls, decreased glucose-induced hyperphagia, and preserved locomotor function. In contrast, ‘Pinova’ extract showed limited and largely concentration-dependent effects across all parameters. These findings suggest that autochthonous apple cultivars with higher (poly)phenolic content like ‘Amarilla de Octubre’ may represent valuable functional food sources for the dietary management of metabolic dysfunction and highlight the nutritional relevance of preserving agrobiodiversity.
