Brief Summary:
Diet macronutrient relative composition, quality and quantity determines lifestyle disease, including cardiovascular disease, development. Our hypothesis is that a high content of carbohydrates in the diet contributes to increased insulin level. Moreover, activating enzymes promoting inflammatory processes and possibly chronic disease development in the body.

Cardiovascular Diseases Chronic Disease Behavioral: "Western" versus "balanced" macro nutrient diet composition Not Applicable

Detailed Description:
The most frequent cause of death in both women and men in the western world is cardiovascular artery disease (CAD). Well accepted as a lifestyle disease, known risk factors for CAD development include changes in blood lipid content and type as well as micro inflammation in the arterial wall. Low density lipoprotein (LDL) and triglycerides are increased, high density lipoprotein (HDL) is reduced. Furthermore, type II diabetes, metabolic syndrome, hypertension, overweight, reduced physical activity and smoking also precede CAD development. Common for many of the risk factors is that they are induced by improper diet. Recent research has shown that especially total amount, composition and quality of the macro nutrients, protein, carbohydrate and fats, is important. In this project we will explore changes in blood gene expression in response to a western and a balanced crossover diet intervention.

Arm Intervention/treatment
Active Comparator: A
Diet A - Western diet
Behavioral: "Western" versus "balanced" macro nutrient diet composition
Randomized crossover diet intervention. 6 days on solely one of two isocaloric diets, 8 days washout, and then the other diet for 6 days. Fasting blood sampling before and after each diet intervention period.
Other Names:
  • western diet
  • high-carbohydrate, low fat, low protein diet
  • balanced diet
  • low-carbohydrate, high fat, high protein diet

Active Comparator: B
Diet B - Balanced diet
Behavioral: "Western" versus "balanced" macro nutrient diet composition
Randomized crossover diet intervention. 6 days on solely one of two isocaloric diets, 8 days washout, and then the other diet for 6 days. Fasting blood sampling before and after each diet intervention period.
Other Names:
  • western diet
  • high-carbohydrate, low fat, low protein diet
  • balanced diet
  • low-carbohydrate, high fat, high protein diet




Primary Outcome Measures :
  1. Changes in microarray gene expression profiles in blood from healthy young women and men, in response to western or balanced dietary macro nutrient composition. [ Time Frame: Before and after each of two 6-days diet intervention periods ]

Secondary Outcome Measures :
  1. Inflammatory markers, hormonal dietary responses and blood lipids [ Time Frame: Before and after each of two 6-days diet intervention periods ]
