The Claim

In women aged 55–69, an increase of 10 grams per day in butter or dairy fat intake is associated with a 4% higher risk of all-cause and ischemic heart disease mortality over a 10-year period.

In plain English

Women aged 55 to 69 who consume 10 more grams of butter or dairy fat per day have a 4% higher risk of dying from any cause or from ischemic heart disease over 10 years compared to those who consume less.

See the scientific wording

In women aged 55–69, each additional 10 grams per day of butter or dairy fat intake is associated with a 4% higher risk of all-cause and ischemic heart disease mortality over a 10-year period, suggesting that high intake of these specific dairy fats may contribute to increased mortality risk in this demographic.

Why this might work

Eating more butter or dairy fat raises levels of bad cholesterol in the blood, which builds up in artery walls and triggers swelling in the blood vessels, leading to heart disease and death.

  1. Study: Dairy consumption and 10-y total and cardiovascular mortality: a prospective cohort study in the Netherlands.

    In women aged 55–69, eating a little more butter or full-fat dairy each day was linked to a tiny but real increase in the chance of dying over 10 years — about 4% more risk for every 10 grams extra. The study found this link clearly and directly.
