The Claim

Early-life exposure to ultra-processed foods and food additives causes persistent alterations in gut microbiota composition and function, which increases the risk of developing metabolic and inflammatory diseases in later life.

In plain English

Exposure to ultra-processed foods and food additives during early life is associated with lasting changes in gut bacteria that increase the risk of metabolic and inflammatory diseases in adulthood.

See the scientific wording

Early-life exposure to ultra-processed foods and food additives may lead to long-term ecological imprinting of the gut microbiota, increasing susceptibility to metabolic and inflammatory diseases later in life.

Why this might work

Eating ultra-processed foods as a child damages the protective mucus layer and tight seals between gut cells, letting harmful bacteria and their toxins leak into the body. This kills off good bacteria that make protective chemicals and lets bad bacteria multiply. The toxins trigger constant low-level inflammation, which disrupts how the body uses sugar and fat, leading to obesity and diabetes later in life.
