Effects of a Nordic diet on cardiovascular and metabolic risk factors in hypercholesterolemic subjects: a randomized controlled study
- 2009
-
Konferensbidrag (refereegranskat)abstract
- Background: Apart from lipid-lowering drugs, dietary changes can also reduce plasma LDL-C concentrations. No studies have been conducted to investigate the clinical effects of a diet with traditional foods originating from the Nordic countries. Method: In a randomised, controlled parallel-group intervention study 88 mildly hypercholesterolemic men and women were randomized to either an ad libitum Nordic diet (ND) or a control diet (CD) for 6 weeks. All meals and foods were provided to the participants in the ND group. Primary outcome measure was LDL-cholesterol, and secondary outcomes were blood pressure, plasma insulin and glucose concentrations. The ND was a high-fibre diet rich in plant foods (fruit, berries, vegetables, root vegetables, whole grain cereals and legumes), vegetable fats (rapeseed oil and nuts) and fatty fish, low-fat milk products, but low in salt, added sugars, saturated fats and red meats. Result: 86 subjects completed the study. Distribution of carbohydrates, fat and protein (E%) in ND was 54, 27, 19, respectively. ND lowered plasma total cholesterol 0.98±0.75 mmol/l (-16%), LDL-C by 0.83±0.67 mmol/l (-21%), HDL-C 0.08±0.23 mmol/l (-5%), including reduced LDL/HDL ratio by -0.42±0.57 (-14%) (all p<0.01 versus controls). Insulin concentrations decreased by 0.51± 2.25 (-9%, p=0.01) and systolic blood pressure by 7±13 mmHg (-5%, P<0.01) compared to controls. Despite diets were eaten ad libitum, body weight decreased by 3.0 kg in the ND (P<0.001). No significant differences were found for diastolic blood pressure, triglycerides or plasma glucose. Conclusion: A Nordic diet improves blood lipid profile, and insulin sensitivity as well as lowering blood pressure to a clinically significant extent in hypercholesterolemic subjects.

Role of a prudent breakfast in improving cardiometabolic risk factors in subjects with hypercholesterolemia : a randomized controlled trial
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background & Aims: It is unclear whether advising a prudent breakfast alone is sufficient to improve blood lipids and cardiometabolic risk factors in overweight hypercholesterolemic subjects.Methods: The aim of the present study was to investigate whether a prudent low-fat breakfast (PB) rich in dietary fiber lowers low-density lipoprotein cholesterol (LDL-C) and other cardiometabolic risk factors in subjects with elevated LDL-cholesterol levels. In a parallel, controlled, 12-week study, 79 healthy overweight subjects (all regular breakfast eaters) were randomly allocated to a group that received a PB based on Nordic foods provided ad libitum or a control group that consumed their usual breakfast. The PB was in accordance with national and Nordic nutrition recommendations and included oat bran porridge with low-fat milk or yogurt, bilberry or lingonberry jam, whole grain bread, low-fat spread, poultry or fatty fish, and fruit.Results: No differences were found in LDL-C, blood lipids, body weight, or glucose metabolism, but SAD, plasma CRP, and TNF-R2 were lower during PB compared with controls (p<0.05). In the overall diet, PB increased dietary fiber and b-glucan compared with controls (p<0.05).Conclusions: Advising a prudent breakfast for 3 months did not influence blood lipids, body weight, or glucose metabolism but reduced markers of visceral fat and inflammation.

- BACKGROUND & AIMS:It is unclear whether advising a prudent breakfast alone is sufficient to improve blood lipids and cardiometabolic risk factors in overweight hypercholesterolemic subjects. The aim of this study was to investigate whether a prudent low-fat breakfast (PB) rich in dietary fiber lowers low-density lipoprotein cholesterol (LDL-C) and other cardiometabolic risk factors in subjects with elevated LDL-cholesterol levels.METHODS:In a parallel, controlled, 12-week study, 79 healthy overweight subjects (all regular breakfast eaters) were randomly allocated to a group that received a PB based on Nordic foods provided ad libitum or a control group that consumed their usual breakfast. The primary outcome was plasma LDL-C. Secondary outcomes were other blood lipids, body weight, sagittal abdominal diameter (SAD), glucose tolerance, insulin sensitivity and inflammation markers (C-reactive protein [CRP] and tumor necrosis factor receptor-2 [TNF-R2]), and blood pressure. The PB was in accordance with national and Nordic nutrition recommendations and included oat bran porridge with low-fat milk or yogurt, bilberry or lingonberry jam, whole grain bread, low-fat spread, poultry or fatty fish, and fruit.RESULTS:No differences were found in LDL-C, other blood lipids, body weight, or glucose metabolism, but SAD, plasma CRP, and TNF-R2 decreased more during PB compared with controls (p < 0.05). In the overall diet, PB increased dietary fiber and β-glucan compared with controls (p < 0.05).CONCLUSIONS:Advising a prudent breakfast for 3 months did not influence blood lipids, body weight, or glucose metabolism but reduced markers of visceral fat and inflammation. The trial was registered in the Current Controlled Trials database (http://www.controlled-trials.com); International Standard Randomized Controlled Trial Number (ISRCTN): 84550872.

Tidskriftsartikel (refereegranskat)abstract
- Background: A healthy Nordic diet (ND), a diet based on foods originating from the Nordic countries, improves blood lipid profile and insulin sensitivity and lowers blood pressure and body weight in hypercholesterolemic subjects. Objective: To describe and compare food and nutrient composition of the ND in relation to the intake of a Swedish reference population (SRP) and the recommended intake (RI) and average requirement (AR), as described by the Nordic nutrition recommendations (NNR). Design: The analyses were based on an estimate of actual food and nutrient intake of 44 men and women (mean age 53 +/- 8 years, BMI 26 +/- 3), representing an intervention arm receiving ND for 6 weeks. Results: The main difference between ND and SRP was the higher intake of plant foods, fish, egg and vegetable fat and a lower intake of meat products, dairy products, sweets and desserts and alcoholic beverages during ND (p<0.001 for all food groups). Intake of cereals and seeds was similar between ND and SRP (p>0.3). The relative intake of protein, fat and carbohydrates during ND was in accordance with RI. Intake of all vitamins and minerals was above AR, whereas sodium intake was below RI. Conclusions: When compared with the food intake of an SRP, ND is primarily a plant-based diet. ND represents a balanced food intake that meets the current RI and AR of NNR 2004 and has a dietary pattern that is associated with decreased morbidity and mortality.
