The Claim

Consuming more than 1,000 grams of non-fermented milk per day is associated with a 34% higher all-cause mortality rate compared to consuming less than 200 grams per day in middle-aged adults from southern Sweden.

In plain English

Middle-aged adults in southern Sweden who drink more than 1,000 grams of non-fermented milk daily have a 34% higher rate of death from any cause than those who drink less than 200 grams daily.

See the scientific wording

Consuming more than 1,000 grams of non-fermented milk per day is associated with a 34% higher all-cause mortality rate compared to consuming less than 200 grams per day in middle-aged adults from southern Sweden, suggesting that very high intake of unfermented dairy may contribute to increased risk of death, though confounding factors cannot be excluded.

Why this might work

Drinking large amounts of milk floods the body with galactose, a sugar that overwhelms the liver’s ability to process it. Excess galactose damages cells through oxidative stress and triggers persistent low-grade inflammation, which harms blood vessels, organs, and tissues over time, increasing the chance of death from multiple causes.

  1. Study: Dairy Consumption, Lactase Persistence, and Mortality Risk in a Cohort From Southern Sweden

    People who drank more than five glasses of regular milk every day were 34% more likely to die over time than those who drank less than one glass, according to a long-term study of Swedes. But eating yogurt or cheese was linked to living longer, so it’s not all dairy — just lots of plain milk.
