Fungal biodiversity and ethnomycological knowledge are fundamental components of the biocultural identity of communities within the La Malinche National Park (PNM), a region of ecological and cultural significance in Mexico. This study documented the diversity of wild fungi and their uses in San Miguel Canoa, Puebla, through field excursions with local mushroom gatherers, interviews, and qualitative analysis. Key species such as Russula delica, Boletus aff. edulis, and Amanita basii were identified, playing a vital role in local gastronomy with traditional recipes like mole and pipián. Intergenerational knowledge transmission, crucial for identifying edible fungi and avoiding intoxications, highlights the importance of oral tradition. However, deforestation, illegal logging, and land-use change threaten fungal diversity, a problem exacerbated by the lack of effective conservation policies. The discussion highlights the interplay between biodiversity and culture, emphasizing the significance of the Wild Mushroom Fair organized by the Yolaltepetl collective as an effort to disseminate ethnomycological knowledge and promote the conservation of the PNM. Such community-driven initiatives represent a sustainable model that integrates environmental protection with cultural strengthening. The study concludes that protecting the PNM requires a holistic approach, merging ecological conservation with the recognition of biocultural knowledge. This is essential to preserve both biodiversity and cultural heritage, ensuring their sustainability for future generations.

Food security among college students is an increasing concern, with potential implications for their health, academic performance, and future well-being. This study investigated food security within a college community in Mexico, focusing on food availability, access (both economic and physical), and consumption patterns. A mixed-methods approach was employed at Ciudad Universitaria, BUAP, Mexico, between 2023 and 2024. Stratified random sampling was used, resulting in a final sample of 606 students. Data were collected through structured questionnaires covering sociodemographic characteristics and eating habits, the ELCSA, structured cafeteria observations, semi-structured interviews with key informants, and three focus groups. Statistical analysis was performed using chi-square tests (p < 0.05). Post hoc analysis with Bonferroni adjustment confirmed that origin (p = 0.0017), mode of transportation (p = 2.31 × 10⁻⁵) and private vehicles (p = 1.77 × 10⁻⁵) were the key determinants. Although the environment offered a variety of options, processed and ultra-processed products dominated the food choices. A total of 95.9% of students purchased food on campus, yet only 21.8% reported engaging in healthy eating habits. Focus groups revealed that students’ food choices were influenced by availability, access, and perceptions of affordability and convenience. These findings highlight the urgent need for targeted interventions to improve food security and promote healthier dietary practices within the college setting.

Socioeconomic disparities have been observed to negatively impact student health by increasing vulnerability to infectious diseases due to opportunistic pa
