The Claim

In adults aged 41–70, a personalized nutrition program results in a greater shift in gut microbiome composition (as measured by Bray-Curtis beta-diversity) and increased abundance of microbial species previously linked to favorable cardiometabolic health compared to standard dietary advice.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

Among adults aged 41–70, a personalized nutrition program changes the gut microbiome more than standard dietary advice, leading to higher levels of microbial species associated with better heart and metabolic health.

See the scientific wording

In adults aged 41–70, a personalized nutrition program led to a greater shift in gut microbiome composition (measured by Bray-Curtis beta-diversity) compared to standard dietary advice, with increased abundance of microbial species previously linked to favorable cardiometabolic health, suggesting that individualized nutrition may more effectively modulate the gut microbiome.

Why this might work

A diet tailored to an individual's metabolic responses changes the types of food they eat, which feeds specific gut bacteria that produce beneficial compounds. These bacteria improve how the body handles fats and reduces inflammation, leading to lower blood triglycerides and less body fat.
