摘要:
Obesity is an increasing health problem in most developed countries and its prevalence is also increasing in developing countries. There has been no great success with dietary means and life style modification for permanent weight loss. Various surgical treatment methods for obesity are now available. They are aimed at limiting oral energy intake with or without causing dumping or inducing selective maldigestion and malabsorption. Based on current literature, up to 75% of excess weight is lost by surgical treatment with concomitant disappearance of hyperlipidaemias, type 2 diabetes, hypertension or sleep apnoea. The main indication for operative treatment is morbid obesity (body mass index greater than 40 kg/m2) or severe obesity (body mass index > 35 kg/m2) with comorbidities of obesity. Orlistat is a new inhibitor of pancreatic lipase enzyme. At doses of 120 mg three times per day with meals it results in a 30% reduction in dietary fat absorption, which equals approximately 200 kcal daily energy deficit. In the long term, orlistat has been shown to be more effective than placebo in reducing body weight and serum total and low-density lipoprotein cholesterol levels. Orlistat has a lowering effect on serum cholesterol independent of weight loss. Along with weight loss, orlistat also favourably affects blood pressure and glucose and insulin levels in obese individuals and in obese type 2 diabetic patients.

摘要:
Renewal has occurred in the use of plant sterols for the treatment of hypercholesterolemias. A novel development was to convert plant sterols to corresponding stanols and esterify them to fat soluble form. In contrast to the crystalline plant sterols or stanols, plant stanol esters can be easily consumed during normal food intake in soluble form in different fat-containing food constituents when they have a potent cholesterol-lowering effect, shown in normo- and hypercholesterolemic men and women without or with coronary heart disease, children and diabetes. Cholesterol lowering is approximately 10% for total and 15% for LDL cholesterol, with the respective values for stanol ester margarine (2–3 g/day stanols) being 15% and 20%. Stanol esters reduce cholesterol absorption efficiency by up to 65%, increase cholesterol elimination in feces as cholesterol itself, usually not as bile acids, and stimulate cholesterol synthesis. Serum beta-carotene level is lowered, but no fat malabsorption or lowering of serum fat soluble vitamins have been observed. In contrast to plant sterols, stanols and their esters are minimally absorbed and they reduce serum plant sterol concentrations, also preventing statin-induced increase of plant sterols. Stanol ester margarine has been included in dietary treatment of hypercholesterolemia followed by the addition of drug treatment in resistant cases.

摘要:
Several studies have examined gene-diet interactions in the response of plasma lipid concentrations to changes in dietary fat and/or cholesterol. Among the gene loci examined, APOE has been the most studied, and the current evidence suggests that this locus might be responsible for some of the interindividual variability in dietary response. Other loci, including APOA4, APOA1 and APOB have also been found to account for some of the variability in the fasting and fed states.

摘要:
Plant foodstuffs are an important source of a wide variety of flavonoids with protective properties on low-density lipoprotein oxidation as shown in vitro and in some human and animal experiments. Increasing information is available concerning the absorption and pharmacokinetics of these molecules, but their long-term protective effect on coronary heart disease still needs further investigation.

摘要:
Available data from several completed large-scale randomized trials indicate that beta-carotene supplementation for durations up to 12 years has no overall benefit in well-nourished populations on the incidence of cardiovascular disease or the middle-to-late stages of carcinogenesis. Several important questions, however, remain unanswered. The post-trial follow-up of completed trials, together with the results of several ongoing trials of beta-carotene supplementation, will contribute reliable information to the totality of evidence from basic research, animal studies, observational epidemiologic studies, and completed trials, thus allowing more rational clinical decisions for individual patients and policy decisions for the health of the general public.

摘要:
Lipoprotein(a) is a plasma particle which is considered to be a risk factor for the development of coronary heart disease. Plasma levels of lipoprotein(a) are affected by different types of dietary fat and steroid hormones. Two regions upstream of the apolipoprotein(a) promoter have been isolated which could be the site of regulation of apolipoprotein(a) gene transcription.

摘要:
Cafestol, a coffee diterpene present in unfiltered coffee brews, potently raises serum lipids in humans. The mechanism through which this dietary compound influences lipoprotein metabolism is largely unknown. Unravelling the mechanism of action might lead to new insights into the regulation of serum cholesterol levels in humans. This review summaries ways in which cafestol may act on serum lipids.

摘要:
The recent discovery of a second estrogen receptor subtype, estrogen receptor-beta, may significantly advance our understanding of tissue specific effects of estrogenic compounds, both natural and synthetic. Although specific effects mediated by estrogen receptor betain vivoremain to be elucidated, hypothetically the existence of two estrogen receptor subtypes (differing in both tissue distribution and biological activity) may help to explain the curious pharmacological behaviour of many estrogenic and antiestrogenic compounds, including the naturally occurring dietary phytoestrogens.
