Primary Outcome Measures :
  1. Changes in dietary pattern [ Time Frame: baseline and 6 months ]

    Dietary pattern will be measured by scoring several aspects of the diet. There are 10 aspets included in the score; fruit consumption, vegetable consumption, fiber intake, fatty acids intake, trans fatty acids intake, physical activity, consumption occasions, alcohol intake, fish consumption and sodium intake.

    The range of the score is from 0 to 100. The score will be based on the information of a Food Frequency Questionnaire and two 24 hour dietary recalls.

Secondary Outcome Measures :
  1. Dietary behaviour [ Time Frame: baseline and 6 months ]
    Behavioral factors influencing dietary intake like barriers for having a healthy diet.

  2. Health outcomes [ Time Frame: baseline and 6 months ]
    Health outcome measure are; BMI, waist and hip circumference, blood lipids (cholesterol and triglycerides) and blood pressure

  3. Markers of intake [ Time Frame: baseline and 6 months ]

    Blood values of carotenoids and fish fatty acids will be used to assess whether measured changes in dietary pattern are also found in the blood.

    Urinary potassium and sodium ratios will also be used to assess changes in dietary pattern.
