Background: The relationship between diet, lifestyle and cognition of old adults has been indicated in several population-based studies. However, the conclusions derived from these studies are inconsistent.
Methods: A cross-sectional study was carried out in 894 old Chinese adults aged 50 and above. Cognitive function of the participants was measured by using Montreal Cognitive Assessment (MoCA) test. Demographic characteristics and lifestyle was collected with a questionnaire. A semi-quantified FFQ method was used for dietary intake survey.
Results: Comparing with normal subjects, mild cognition impairment (MCI) patients were characterized as old age and lower education (P<0.01). The nuts and cooking oil intake of MCI patients was less than the normal subjects (P<0.05). Fruit and vegetable intake will benefit orientation, name and attention ability in the elderly (P<0.05). Fruit and vegetable juice drinking will benefit abstraction ability (P<0.01).Subjects with regular reading and housekeeping habit had better cognition (P<0.01).
Conclusions: Nuts, vegetables and fruit-rich diet might decrease the risk of cognition impairment. Reading and housekeeping help to maintain healthy cognition in the elderly.

Gastric cancer, a prevalent malignant tumor worldwide, poses a significant challenge to global health. Despite ongoing advancements in treatment methods, its high incidence and mortality rates remain concerning. Although progress in treating gastric cancer is encouraging, a more critical focus is on enhancing prevention efforts.

Metabolomics has demonstrated its potential to enable exciting discoveries in brain health, facilitated by advances in analytical and informatics techniques. Here, we highlighted the use of MS/MS-based untargeted metabolomics to study the diet and medication exposure of cognitively declined cohorts through the newly developed FoodMASST and DrugMASST tools.

Insomnia in late life is influenced by a wide array of genetic and lifestyle factors, some of which exhibit sex-dependent effects. This study examined whether selected single nucleotide polymorphisms (SNPs) related to the neurotrophin, brain-derived neurotrophic factor (BDNF), or its receptors and lifestyle factors, and their interactions were associated with the increased risk for sleep disturbance in older males and females.

Here, we test the feasibility of a new risk reduction program called Brain Wellness Information, Support, and Empowerment (Brain-WISE). Its unique features are that it (1) is aligned with a theoretical model of behavior change, (2) is relatively brief (six 90-min sessions), (3) is conducted with groups of people who have pre-existing community; (4) includes individual and group activities and person-centered health goals; and (5) is conducted with speech-language therapists.
