Effects on blood lipids of a blood pressure-lowering diet: the Dietary Approaches to Stop Hypertension (DASH) Trial.

BACKGROUND: Effects of diet on blood lipids are best known in white men, and effects of type of carbohydrate on triacylglycerol concentrations are not well defined. OBJECTIVE: Our goal was to determine the effects of diet on plasma lipids, focusing on subgroups by sex, race, and baseline lipid concentrations. DESIGN: This was a randomized controlled outpatient feeding trial conducted in 4 field centers. The subjects were 436 participants of the Dietary Approaches to Stop Hypertension (DASH) Trial [mean age: 44.6 y; 60% African American; baseline total cholesterol: < or = 6.7 mmol/L (< or = 260 mg/dL)]. The intervention consisted of 8 wk of a control diet, a diet increased in fruit and vegetables, or a diet increased in fruit, vegetables, and low-fat dairy products and reduced in saturated fat, total fat, and cholesterol (DASH diet), during which time subjects remained weight stable. The main outcome measures were fasting total cholesterol, LDL cholesterol, HDL cholesterol, and triacylglycerol. RESULTS: Relative to the control diet, the DASH diet resulted in lower total (-0.35 mmol/L, or -13.7 mg/dL), LDL- (-0.28 mmol/L, or -10.7 mg/dL), and HDL- (-0.09 mmol/L, or -3.7 mg/dL) cholesterol concentrations (all P < 0.0001), without significant effects on triacylglycerol. The net reductions in total and LDL cholesterol in men were greater than those in women by 0.27 mmol/L, or 10.3 mg/dL (P = 0.052), and by 0.29 mmol/L, or 11.2 mg/dL (P < 0.02), respectively. Changes in lipids did not differ significantly by race or baseline lipid concentrations, except for HDL, which decreased more in participants with higher baseline HDL-cholesterol concentrations than in those with lower baseline HDL-cholesterol concentrations. The fruit and vegetable diet produced few significant lipid changes. CONCLUSIONS: The DASH diet is likely to reduce coronary heart disease risk. The possible opposing effect on coronary heart disease risk of HDL reduction needs further study.

Status and management of blood lipids in Greek adults and their relation to socio-demographic, lifestyle and dietary factors: the ATTICA Study. Blood lipids distribution in Greece.

OBJECTIVE: In this work, we assessed the status and management of blood lipids in a sample of cardiovascular disease free adult men and women from Greece. We also evaluated the effect of several socio-demographic, dietary and lifestyle habits on lipid levels. METHODS: The ATTICA Study is a population-based cohort that has randomly enrolled 1128 men and 1154 women (aged >18 years old), stratified by age-gender, from the greater area of Athens, during 2001-2002. Adherence to Mediterranean diet was assessed through a diet score that was based on a validated food-frequency questionnaire. RESULTS: Forty-six percent of men and 40% of women had total serum cholesterol levels >200mg/dl. Of them, 40% of men and 30% of women were unaware of their condition. Twenty-one percent of men and 7% of women had HDL-cholesterol levels <35 mg/dl. Twenty-eight percent of men and 13% of women had triglyceride levels >150 mg/dl. Fifteen percent of men and 12% of women had LDL-cholesterol levels >160 mg/dl and 52% of men and 48% of women had LDL >130 mg/dl. Of those who had known blood lipid abnormalities, 36% of men and 33% of women followed a dietary medication, 31% of men and 20% of women were receiving a pharmaceutical treatment (mainly statin) and the rest were untreated. Participants who adopted the Mediterranean diet and received statin, had on average 9% lower total cholesterol (P = 0.04), 19% lower LDL-cholesterol levels (P = 0.02) and 32% lower oxidized LDL-cholesterol levels (P < 0.001) compared to those who were untreated and adopted a Westernized diet. CONCLUSIONS: We could speculate that about 3 million Greek adults had high total cholesterol levels. Adverse findings were also observed regarding the other investigated blood lipids. Mediterranean diet could be a complimentary mean to pharmaceutical treatment in reducing blood lipids.

Long-chain omega 3 fatty acids, blood lipids and cardiovascular risk reduction.

Increasing evidence suggests that omega 3 fatty acids derived from fish and fish oils may play a protective role in coronary heart disease and its many complications, through a variety of actions, including effects on lipids, blood pressure, cardiac and vascular function, prostanoids, coagulation and immunological responses. Interesting differences between the effects of highly purified eicosapentaenoic acid and docosahexaenoic acid are emerging, which may be relevant in the choice of omega 3 fatty acid for incorporation into food products. On the basis of our current knowledge, we believe it is justified to recommend, particularly to high-risk populations, an increased dietary intake of omega 3 fatty acids through the consumption of fish.

[Lipid blood spectrum in patients with amiodarone associated hypothyroidism. Effect of replacement therapy with L-thyroxine].

Blood lipid levels were measured in 23 patients with amiodarone associated hypothyroidism (most of them had ischemic heart disease). Abnormalities of lipid spectrum were found in 12 of these patients. All 12 patients were subjected to replacement therapy with l-thyroxine. Compensation of thyroid status was associated with average 12.6 and 12.3% lowering of total and low density lipoprotein cholesterol, respectively. However target levels of low density lipoprotein cholesterol were achieved only in 1 patient. There were no significant changes of high density lipoprotein cholesterol and triglycerides.

[Indicators of lipid metabolism and the blood lipid peroxidation system in men with regard to hereditary predisposition to atherosclerotic vascular pathology].

Lipid metabolism and the blood lipid peroxidation system were examined in 56 military males living in rather similar conditions. The parameters in question were compared in the following groups: (1) control subjects, including healthy individuals without a family history of atherosclerotic vascular abnormalities; (2) healthy subjects with a family history of atherosclerosis; (3) patients with coronary heart diseases. There were significant differences only in single cases between the groups. The application of a system of grids setting upright the distribution curves for the parameters under study proved to be effective in finding significant differences between the groups, showing the value of the hereditary factors in the development of atherogenic lipid changes.

Long-term supplementation with n-3 fatty acids, I: Effect on blood lipids, haemostasis and blood pressure.

The effect of dietary supplementation with 4 g of n-3 polyunsaturated fatty acids (PUFA) daily for 9 months on blood pressure, plasma lipids and lipoproteins, platelet function, coagulation and fibrinolysis was studied in 24 healthy volunteers. Each variable was determined before, after 6 weeks and 9 months of supplementation with n-3 PUFA, and 3 months after the supplementation period had ended. Systolic and diastolic blood pressure declined after intake of n-3 PUFAs. Plasma triglycerides were reduced, and there was a trend towards an increase in HDL-cholesterol after 9 months of supplementation, while total cholesterol, LDL-cholesterol and apolipoproteins A1 and B were unaltered. The bleeding time was increased, and plasma levels of von Willebrand factor decreased after 9 months supplementation with n-3 PUFA. Fibrinogen levels increased, while fibrinolysis was reduced after 9 months supplementation with n-3 PUFA. Overall, no clear benefit on lipid pattern and haemostasis was achieved with respect to development of coronary heart disease.

[Preliminary considerations on blood lipid parameters and blood insulin after oral glucose tolerance test].

The behaviour of total lipids, triglycerides and apolipoproteins A and B has been investigated in 41 subjects whose glucose and insulin levels have been evaluated after oral glucose tolerance test. Some of the patients showed a normal glycemic response, others a reduced glucose tolerance. Patients with a normal glycemic curve and a normal pattern of insulin values after loading had low mean total lipids and triglycerides and elevated Apolipo A values. Furthermore, subjects with altered glycemic curve and normal insulin levels presented high mean total lipids and triglycerides and low Apolipo A values. In conclusion we observed, in agreement with other authors, that a good blood insulin reaction is a favourable factor for the reduction of serum triglyceride levels, probably by activation of lipoproteinlipase, with a slight mean increase of apolipoproteins A.

Post-traumatic blood lipid changes and fat embolism. Relation of post-traumatic blood lipid changes and fat embolism syndrome.

Serum cholesterol, triglycerides, phospholipids, and lipoprotein levels were studied by electrophoresis in 43 trauma patients with multiple fractures of the lower extremities and pelvis. Ten healthy volunteers were used for control studies. The fat embolism syndrome was diagnosed in eight of the 43 patients. The lipid values of all the trauma patients were lower than the control values. A decrease in cholesterol and phospholipids was observed in the fat embolism patients during 4 days; these changes were not observed in the other trauma patients. The triglycerides of all the trauma patients increased slowly over a period of 4 days. Changes in the lipoprotein fractions after the trauma were minor. An early increase in the alpha1 lipbrotein fraction was noted in the fat embolism patients simultaneously with a decrease in the pre-beta lipoprotein fraction; the values of the other trauma patients were at the control levels. Normalization was observed in 6 hours. The lipid concentrations of plasma and serum did not change with filtration with 1.2, 5, and 8mum Millipore filters. No differences were noted between the femoral and cubital vein samples.
