The Claim

No association was observed between the intake of total fat or any specific fatty acid subgroup—including saturated, polyunsaturated, monounsaturated, trans, or omega-6 fats—and progression of age-related macular degeneration over a 7-year period in individuals with early-stage disease.

Source: Dietary lutein, zeaxanthin, and fats and the progression of age-related macular degeneration.

Supports is higher

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

In plain English

Over seven years, people with early-stage age-related macular degeneration who consumed different amounts of total fat or specific fatty acids showed no difference in disease progression.

See the scientific wording

No association was observed between the intake of total fat or any specific fatty acid subgroup—including saturated, polyunsaturated, monounsaturated, trans, or omega-6 fats—and progression of age-related macular degeneration over a 7-year period in individuals with early-stage disease.

Why this might work

The cells in the back of the eye maintain their fat balance regardless of how much fat a person eats, so the disease does not get worse or better based on dietary fat intake.

What the research says

1 study
  1. Study: Dietary lutein, zeaxanthin, and fats and the progression of age-related macular degeneration.

    The study found that eating more or less of any kind of fat—like butter, oil, or nuts—didn’t make early eye disease worse or better over seven years. So, fat intake doesn’t seem to affect how fast the eye condition progresses.
