What researchers measure

Primary outcomes

  1. Average Nutritional Knowledge Score (NK)

    Studies often show average scores around 50-60% of correct answers. Knowledge is often measured as a percentage of a total possible score, with a 75% threshold sometimes used to define "basic" or "good" knowledge.

    Time frame: through study completion, an average of 1 year

  2. Mediterranean Diet Adherence (AMD) value

    High Mediterranean Diet Adherence (AMD) is strongly linked to a reduced risk of developing and progressing to advanced Age-Related Macular Degeneration (AMD), with studies showing 34% to 60% lower risk compared to low adherence. A diet rich in vegetables, fruits, and nuts significantly lowers this risk.

    Time frame: through study completion, an average of 1 year

Secondary outcomes

  1. Hand Grip test

    muscle strength parameters

    Time frame: through study completion, an average of 1 year

  2. fasting blood glucose (mg/dL)

    metabolic compensation parameters

    Time frame: through study completion, an average of 1 year

  3. glycated haemoglobin (mmol/mol)

    metabolic compensation parameters

    Time frame: through study completion, an average of 1 year

  4. lipid profile (mg/dL)

    metabolic compensation parameters

    Time frame: through study completion, an average of 1 year
