In the Personalized Nutrition Project and subsequent interventional trials, personalized dietary modifications led to improvements in HDL cholesterol.

"So, for example, in the Personalized Nutrition Project and in interventional trials that were followed as part of this project, we found that modification of the personalized nutritional recommendations could lead to an improvement in HDL cholesterol, the good cholesterol." (said at 0:32:37)

The Personalized Nutrition Project investigated machine-learning algorithms incorporating microbiome, dietary, anthropometric, and clinical blood markers to design personalized diets targeting postprandial glycemic responses. In randomized dietary interventions from the project, personalized diets significantly reduced postprandial glycemic excursions and modified metabolic and microbiome profiles. While cardiometabolic parameters and blood lipids are tracked as broader metabolic consequences of these personalized dietary interventions, the primary focus of the foundational trials was glycemic control.

"Finally, a blinded randomized controlled dietary intervention based on this algorithm resulted in significantly lower postprandial responses and consistent alterations to gut microbiota configuration. Together, our results suggest that personalized diets may successfully modify elevated postprandial blood glucose and its metabolic consequences." (abstract, results, passage verified)

For some individuals, eating tomatoes alone causes a sharp rise in blood glucose, whereas combining tomatoes with white bread reduces the glycemic response.

"Some people spike their blood sugar to the roof when they eat tomatoes. Now you combine tomatoes with some white bread and the response goes down." (said at 1:48:29)

In a 2015 study of personalized glycemic responses in an 800-person cohort (Zeevi et al., PMID 26590418), researchers continuously monitored postprandial blood glucose levels and observed high interpersonal variability in response to identical foods, including cases where specific participants showed unexpected glycemic spikes to individual foods. However, claims describing extreme paradoxical responses—such as a sharp glycemic spike from tomatoes alone that decreases when combined with white bread—rely on anecdotal highlights or informal presentations of individual participant data from continuous glucose monitoring cohorts rather than established, peer-reviewed findings showing that adding high-glycemic carbohydrates like white bread lowers overall postprandial glucose excursions compared to vegetables alone.

"we continuously monitored week-long glucose levels in an 800-person cohort, measured responses to 46,898 meals, and found high variability in the response to identical meals, suggesting that universal dietary recommendations may have limited utility." (abstract, passage verified)
