Renowned researcher Felice N. Jacka’s work, focusing on the relationship between diet, gut microbes, and mental health, brings forth a groundbreaking perspective on astronaut nutrition for potential Mars missions. Her studies, backed by a National Health and Medical Research Council investigator grant and various other supports, highlight the pivotal role of diet not just in physical health, but also on mental and brain health.

Unlocking the Power of Diet

Jacka’s research emphasizes the significance of the microbiota-gut-brain axis. She demonstrates that dietary improvements can lead to enhanced mental health outcomes. Furthermore, she identifies that certain dietary components, including long chain omega-3 fatty acids and flavonoids, can boost cognitive performance. These findings carry profound implications for astronaut nutrition, particularly for future long-duration space missions.

Astronaut Nutrition for Mars Missions

As a mission to Mars, projected for the late 2030s or early 2040s, looms on the horizon, the challenges of space travel necessitate an all-round approach to nutrition. It isn’t simply about providing astronauts with adequate nutrients and calories, but also about maintaining their mental and cognitive health through an appropriate diet. Such a diet needs to be diverse, appealing, nutritious, compact, and capable of supporting a balanced gut microbiome.

Feeding Strategies and the Microbiome

Jacka’s research proposes the inclusion of phytonutrients, fermentation products, and beneficial microbes in space food. Recognizing that humans have coevolved with trillions of microbes that impact numerous bodily functions, maintaining a diverse and healthy microbiome becomes crucial for astronauts. The insights gained from these studies will contribute to the development of feeding strategies that support both physical and mental well-being of astronauts, paving the way for potential settlement on Mars.
