Article Synopsis
- Diet diversity (DD) during infancy might help prevent food allergies (FA) by promoting exposure to varied foods, which is beneficial for the gut microbiota.
- The study tracked a birth cohort from 2001-2002 and evaluated the link between DD and FA development across ten years, measuring DD using various criteria at different infant ages.
- Results showed that greater DD at 6 and 9 months significantly lowered the odds of developing FA, indicating that introducing a diverse diet early in life could be crucial for long-term health.

Article Abstract
Background: Diet diversity (DD) during infancy may prevent food allergies (FA), possibly by exposing the gastrointestinal microbiota to diverse foods and nutrients.
Objective: To investigate the association between 4 different measures of DD during infancy and development of FA over the first decade of life.
Methods: A birth cohort born between 2001 and 2002 were followed prospectively, providing information on sociodemographic, environmental, and dietary exposures. Information on age of introduction of a range of foods and food allergens was collected during infancy. Children were assessed for FA at 1, 2, 3, and 10 years. DD was defined using 4 measures in the first year of life: the World Health Organization definition of minimum DD at 6 months, as food diversity (FD) and fruit and vegetable diversity (FVD) at 3, 6, and 9 months, and as food allergen diversity (FAD) at 3, 6, 9, and 12 months.
Results: A total of 969 pregnant women were recruited at 12-week gestation. A total of 900, 858, 891, and 827 offspring were assessed at 1, 2, 3, and 10 years. Univariate analysis showed that World Health Organization DD (P = .0047), FD (P = .0009), FAD (P = .0048), and FVD (P = .0174) at 6 months and FD (P = .0392), FAD (P = .0233), and FVD (.0163) at 9 months significantly reduced the odds of FA over the first decade of life. DD measures at 3 months were not associated with FA, but only 33% of the cohort had solid foods introduced by this age.
Conclusion: Increased infant DD, as measured by 4 different methods, decreased the likelihood of developing FA.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Background: Red and processed meat consumption is extensively linked to chronic disease risk in observational studies, with robust meta-analyses demonstrating significant positive associations for colorectal, breast, endometrial, and lung cancers, type 2 diabetes (T2DM), cardiovascular disease (CVD), and all-cause mortality. Dose-response relationships indicate elevated risks even at moderate intakes. Moreover, processed meats consistently show stronger detrimental effects than unprocessed red meats.

The sine qua non of intervention studies in general, and randomized controlled trials in particular, is to define and isolate an exposure of interest that defines the intervention and distinguishes between groups. The isolation of a presumptive cause is prerequisite to the confident attribution of given effects. In the context of dietary intervention studies, this has historically translated into a unitary intervention diet type, no matter the diversity of preferences, tastes, upbringings, ethnicities, and cultures represented in a given study cohort.

The global incidence of early-onset cancer has surged by nearly 80% over the past three decades, yet the underlying causes remain poorly understood. While genetics and lifestyle are among the traditional risk factors, emerging evidence implicates the human microbiome as a potent and overlooked contributor to early tumorigenesis. Increases in the studies that are exploring the tissue-specific microbiome signatures such as the enrichment of Actinomyces and Bacteroidia in early-onset colorectal cancer, or Enterobacter and Neisseria in pancreatic tumors offer compelling evidence for age-stratified microbial contributions.
