The Mediterranean Diet Was Bested By The PPT Diet For Post-Meal Blood Sugar Response
What is a personalized postprandial-targeting diet?
By comparison, a PPT diet is, according to the researchers, a diet that "relies on a machine learning algorithm that integrates clinical and microbiome features to predict personal postprandial glucose responses," also known as the post-meal glucose response. Unlike diets like the Mediterranean diet, it is not a generalized set of guidelines for any person but rather is highly personalized to the individual.
How did the diets affect post-meal blood sugar?
The study had 225 adults with prediabetes either follow a MED diet or a PPT diet for six months, with an additional six-month follow-up. All participants used continuous glucose monitors (GCM) for the duration of the study and follow-up.
Researchers found that both groups saw a reduction in the time that their daily glucose levels were over normal levels (over 140 mg/dL), but the group who followed a PPT diet saw significantly greater reductions, even during the full 12-month follow-up.
The bottom line.
While the Mediterranean diet may be often considered one of the most healthy options for dietary guidelines, this research suggests that for people with prediabetes, following a more personalized plan like the PPT diet may be more effective at managing blood sugar spikes, especially after meals.
