Summary
High-dose eicosapentaenoic acid (EPA)-only omega-3 fatty acids (O3FAs) significantly reduce cardiovascular disease events in high-risk patients. Prescription EPA formulations offer greater benefits than mixed EPA/docosahexaenoic acid (DHA) or other O3FAs.
Area of Science:
- Cardiology
- Biochemistry
- Nutritional Science
Background:
- Omega-3 fatty acids (O3FAs) are linked to cardiovascular (CV) health benefits, yet clinical trial results with various O3FA formulations are inconsistent.
- Low-dose eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) mixtures have failed to prevent CV events in primary and secondary prevention.
Approach:
- This review analyzes clinical findings from trials using different O3FA formulations.
- It examines the efficacy of EPA-only versus EPA/DHA or other O3FAs in cardiovascular disease (CVD) prevention.
- Mechanisms of action, including effects on lipids, inflammation, and endothelial function, are discussed.
Key Points:
- EPA-only formulations, like those in JELIS and REDUCE-IT, significantly reduce CVD events in high-risk individuals.
- Achieved EPA levels, not just triglyceride or LDL reduction, correlate with event reduction.
- EPA exhibits distinct biological effects compared to DHA, influencing atherosclerotic plaque, oxidation, and endothelial function.
Conclusions:
- Prescription-grade, EPA-only omega-3 fatty acid formulations demonstrate superior efficacy in reducing cardiovascular events compared to other tested O3FA formulations.
- The unique properties of EPA are crucial for its cardiovascular benefits, independent of broad lipid-lowering effects.

03:38Structure of Lipids
88.3K
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...

01:30Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
334
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

01:18Lipids: Dietary Sources and Requirements
744
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...
