In our study, we measured the effects of food intake by focusing on blood glucose responses, which are crucial for understanding how different foods affect individuals differently.

Participants logged their food intake using an app, allowing us to analyze their dietary habits alongside their glucose responses for a comprehensive understanding of personalized nutrition.

In our study with 26 participants, we designed diets to either reduce or increase blood glucose levels, demonstrating that personalized diets can effectively manage glucose responses.

We found that people's glucose responses to the same food can vary significantly, indicating that individual responses to foods are not categorically good or bad but depend on the person.

We developed an algorithm that predicts people's glucose responses to meals based on their microbiome composition and other health metrics, achieving a correlation of 0.68, which is significantly better than previous methods.

Current research is focusing on measuring insulin responses to different food types, which could provide insights into personalized dietary recommendations.

The collaboration between different research groups at Stanford has been essential for studying the impact of diet on the microbiome and human health, allowing for comprehensive human studies. We can monitor hundreds to thousands of different parameters in the immune system longitudinally from a blood draw, allowing us to see how the immune system changes in concert as we change the microbiome with diet.

We found that bowel habits improved during both dietary interventions, which can lead to better moods, although we couldn't measure this directly in the study.

We instructed participants to avoid sugary yogurts, emphasizing the importance of consuming non-sweetened varieties to maximize health benefits from fermented foods.
