8 Clinical Trials for Various Conditions
The purpose of this study is to examine whether the daily consumption of 5 g of milk polar lipids influences serum lipids and gut microbiota composition in healthy adults.
Background: * Cardiovascular disease (CVD) is a leading cause of death in developed countries. Although statin-type drugs are currently the most effective therapeutic agents for reducing CVD risk. One possible complementary approach involves the use of soluble dietary fibers that are known to reduce blood cholesterol levels. However, analysis has shown that most soluble fibers reduce total cholesterol levels by relatively small amounts. * Alpha-Cyclodextrin (Alpha-CD), also sold in commerical form, is a soluble fiber derived from corn that is used as an ingredient in many foods, such as bread rolls, crackers, juices, and reduced fat spreads. It is added to food primarily as a fiber supplement but is also used to stabilize flavors, colors, vitamins, and fatty acids. Studies in animals and humans have shown that Alpha-CD may help to improve insulin resistance and lower LDL cholesterol levels with no apparent side effects. More research is needed to determine the effect of Alpha-CD on total cholesterol levels in healthy volunteers. Objectives: - To determine the effect of oral Alpha-CD on total cholesterol in a nondiabetic population.
A diet-controlled clinical trial which attempts to provide estimates of the effect of black tea consumption on serum lipids under tightly controlled conditions, including a controlled diet. Mildly hypercholesterolemic individuals (total cholesterol levels between 4.9 and 6.7 mmol/L, 190 and 260 mg/dl), non-smoking, chronic disease-free individuals were enrolled in a 15-week, double blind, randomized crossover trial, during which they consumed a controlled low-flavonoid diet plus 5 cups of black tea or a tea-like placebo over two 4-week treatment periods.
Purpose: To demonstrate the efficacy of Beneflax™ flaxseed lignan (SDG) concentrate to lower serum cholesterol levels. Background: Flaxseed has been studied for various health benefits in humans, including prostate health, glucose control, and cardiovascular health. Cholesterol levels and high blood pressure are known to be risk factors for cardiovascular disease. Whole flaxseed has had variable effects on serum lipid levels, perhaps a consequence of variations in the amounts of secoisolariciresinol diglucoside (SDG) found in different flax cultivars, making the study of this bioactive compound difficult. Hypothesis: Flaxseed lignan (SDG) extract (Beneflax) significantly lowers total and LDL cholesterol. Flaxseed lignans also lower blood pressure and fasting glucose levels.
The Habitual Diet and Avocado Trial will evaluate the effects of providing one avocado per day for recommended consumption over a 6 month period in a cohort of approximately 1000 free-living participants with increased waist circumference in comparison with a control group that will maintain their habitual diets. Participants will be recruited and screened at 4 clinics in 4 locations: Pennsylvania State University; Loma Linda University; UCLA, and Tufts University (250 per site).
Approximately 24% of the US adult population meet criteria for metabolic syndrome (MetS), diagnosed by a combination of abdominal obesity, elevated blood pressure, high triglyceride and low HDL-cholesterol level, and pre-diabetes. MetS quintuples the risk of diabetes, and doubles the risk of cardiovascular disease (CVD), particularly heart failure. Lifestyle modification is the initial step of treatment, but few studies have demonstrated early and sustained efficacy in remission of MetS. Our preliminary studies of a lifestyle change program for patients with MetS included a 1-year of development of an intervention by an interdisciplinary team of experts in medicine and the behavioral sciences. The investigators then tested the efficacy of the intervention in a treatment-only, proof-of-concept study. The investigators achieved our goal of 50% MetS remission after 2 years, in a sample of 26 patients. This study is the second step of a research program testing an innovative bio-behavioral intervention aimed at remitting MetS through lifestyle intervention, by focusing on eating patterns, daily activity, and stress management. The overarching objective of this research program is to determine the efficacy of the ELM lifestyle intervention to achieve remission of MetS. This purpose of the current study is to prepare for a large, randomized, clinical trial by conducting a smaller clinical trial that examines the acceptability of the ELM intervention (ELM Group) as compared to two other intervention arms (ELM Classes, ELM Individual).
The purpose of this study is to determine the genetic basis of one family's hereditary hyper-HDL-emia using multiple modalities such as linkage analysis and gene array.
This is a double-blind, placebo-controlled study to assess the effectiveness of BiosLife in lowering serum LDL cholesterol and raising HDL cholesterol. BiosLife is a natural supplement (mixed in water and taken twice daily) which contains guar gum and other natural soluble fibers, phytosterols, policosanol, and a proprietary chrysanthemum extract. Approximately 100 subjects with baseline LDL cholesterol of 110-190 mg/dL will be randomized in a 2:1 ratio to BiosLife or a look-alike placebo. Changes in lipids from baseline will be assessed at 6 weeks and 12 weeks.
