NCT01739153

Brief Summary

The main objective of the current study is to examine whether a high intake of regular-fat cheeses (Danbo and Cheddar) affect blood lipids differently than an isocaloric intake of either other fatty animal food products or of starchy carbohydrates. Furthermore, effects on fat digestibility, blood pressure, anthropometry, bile acid metabolism and insulin sensitivity is investigated. To do this, a randomized crossover intervention study with 3x14 days full diet periods (cheese diet, meat diet or carb diet)will be conducted in 16 postmenopausal women. Between the diet periods there will be at least 14 days of wash-out where the subjects eat their habitual diets. Fasting blood samples will be drawn before and after the diet periods, and also a non-fasting blood sample will be drawn after the diet periods. Furthermore, total feces is collected the last 5 days of each diet period.

Study Arms (3)

CARB diet

EXPERIMENTAL

The CARB diet will be a low-fat diet where cheese is replaced by starchy carbohydrates and lean meat. The CARB diet will have the same protein content (15 E%) and quality as the CHEESE and MEAT diet but a lower fat content (approx. 25 E%) and a correspondingly higher carbohydrate content (approx. 60 E%).

Other: Dietary intervention: CARB (High Carbohydrate intake)

CHEESE diet

EXPERIMENTAL

The CHEESE diet will contain cheese in amounts corresponding to 120 g/day on a 10 MJ diet (approx. 1.8 MJ from cheese). A high dose of cheese is chosen to provoke effects within this short time frame. The cheese types used in this study will be Danbo (45+) and Cheddar (50+) which will be supplied in equal amounts. The CHEESE diet will have the same macronutrient composition as that of the average Danish diet (15 E% from protein, max 35 E% from fat, and max 15 E% from saturated fat).

Other: Dietary intervention: CHEESE (High cheese intake)

MEAT diet

EXPERIMENTAL

The MEAT diet will be a diet without dairy products. In this diet cheese is mainly replaced by high-fat mixed meat products to achieve saturated fat content and protein quality similar to that of the CHEESE diet. The MEAT diet will have the same macronutrient composition as that of the average Danish diet (15 E% from protein, max 35 E% from fat, and max 15 E% from saturated fat).

Other: Dietary intervention: MEAT (High Meat intake)
