Nutrition-based Interventions to Prevent Cognitive Decline

In person lifestyle group sessions of 180-minutes per week, directed by a nutritionist, and comprising: 1. nutrition education session for preparing healthy meals, followed by a period of social interaction while consuming the meals prepared. Participants will be encouraged to apply the healthy cooking techniques covered in each session in their home context. 2. daily activities to reduce physical inactivity (e.g., walking to the supermarket to buy ingredients, playing traditional games, caring for community gardening, among others).

Individualized cognitive training performed remotely, at home on their own. The participants will be invited to perform cognitive training exercises at least twice a week using COGWEB®, an online platform for cognitive training. For those unable to use computer devices, similar exercises will be available in paper-and-pencil format.

A registered nutritionist will conduct individualized clinical nutrition consultations to each participant three times over the course of the study period.
