Cardioprotective and Mental Health Benefits of the MIND Diet Combined With Forest Bathing

These participants will receive four nutrition information sessions, 60 minutes per session, on four consecutive weekdays at the participating community centre. A 7-day sample menu will be developed and explained to the participants as a reference. A nutritionist with the help of a research assistant will conduct each session. The nutritionist-to-participant ratio for each session will be 1:10, 1:11 or 1:12. The following topics will be covered: (1) overview of the MIND diet; (2) discussion with the participants about their ability, motivation and opportunity to adopt the MIND diet; and (3) instruction on how to adopt the MIND diet and how to fill out a logbook for adherence checks.

The sessions will include four nutritional sessions about the MIND diet and four FB sessions. The participants will be instructed on the MIND diet as previously mentioned. In addition, the MIND-FB participants will undertake four 2 h FB sessions in a country park on four consecutive weekends during daytime hours. The FB sessions will take place during the day if it is sunny, cloudy or lightly raining. The distance covered on each forest visit will be 1-2 kilometres. If it is raining heavily, the session will be cancelled. The participants will gather at the entrance of the country park on the day of FB.
