Omega-3 polyunsaturated fatty acids and brain health: Preclinical evidence for the prevention of neurodegenerative diseases.
Conclusions These studies have shown that dietary n-3 PUFA treatments consistently improve cognitive performance in animal models and may also exert disease-modifying actions. N-3 PUFA also provide protection to dopaminergic neurons in animal models of PD and possibly recovery after lesion. Furthermore, some of these effects might depend on specific diet formulations to protect long-chain fatty acids from oxidation or synergies with other nutrients. More generally, this review aims at providing evidence that adjustments in the consumption of dietary lipids alone or combined with other nutrients may be a cost-effective inte...

New class of molecules may protect brain from stroke, neurodegenerative diseases
(Louisiana State University Health Sciences Center) Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans, has discovered a new class of molecules in the brain that synchronize cell-to-cell communication and neuroinflammation/immune activity in response to injury or diseases. Elovanoids (ELVs) are bioactive chemical messengers made from omega-3 very long chain polyunsaturated fatty acids (VLC-PUFAs,n-3). They are released on demand when cells are damaged or stressed.

Marine OMEGA-3 fatty acids in the prevention of cardiovascular disease.
Abstract Omega-6 (ω6) and omega-3 (ω3) fatty acids are two classes of dietary polyunsaturated fatty acids derived from linoleic acid (18:2ω6) and α-linolenic acid (18:3ω3), respectively. Enzymatic metabolism of linoleic and α-linolenic acids generates arachidonic acid (20:4ω6) and eicosapentaenoic acid (20:5ω3; EPA), respectively, both of which are substrates for enzymes that yield eicosanoids with multiple and varying physiological functions. Further elongation and desaturation of EPA yields the 22-carbon fatty acid docosahexaenoic acid (22:6ω3; DHA). The main dietary source of EPA and DHA for human cons...

Review of Cardiometabolic Effects of Prescription Omega-3 Fatty Acids
AbstractPurpose of ReviewPopulations with significant dietary fish intake tend to have lower cardiovascular (CV) risk and demonstrable physiologic differences including lower lipid/lipoprotein levels and other direct and indirect effects on the arterial wall and inhibiting factors that promote atherosclerosis. Treatment with high doses of pharmacologic-grade omega-3 fatty acid (n-3FA) supplements achieves significant reductions in triglycerides (TG), non-high-density lipoprotein- (non-HDL-) and TG-rich lipoprotein- (TRL-) cholesterol levels.n-3FA supplements have significant effects on markers of atherosclerosis risk inclu...

Can Fish Oil Help Reading?
Discussion Fats and fatty acids are essential for good human health. Saturated fats have hydrogen pairs linked to each carbon on the carbon backbone. They are solid or semi-solid at room temperature. Common examples are butter, lard, or hardened vegetable shortening. They are linked to higher cholesterol and triglycerides and only a small amount of them are recommended to be consumed in the diet. Unsaturated fats have one or more hydrogen atoms missing from the carbon backbone. They are liquid at room temperature. Monounsaturated fatty acids have one hydrogen pair that is missing from the carbon backbone. They are liq...

A New Form of This Miracle Nutrient Is 8 Times More Powerful …
CoQ10 has made the mainstream. You can find it everywhere. But the type of CoQ10 I want to tell you about has been completely ignored. That’s too bad, because this new form is 8 times better at getting into your blood and staying there. And that’s where it has its miracle-like anti-aging effects. This new form of CoQ10 may give you the opportunity to live disease-free for the rest of your life. Today, I’ll show you how this new “reduced” form of CoQ10 gives you greater power to prevent and reverse disease. You’ll also discover that it ramps up your energy levels and slows your aging process down by a remarkable...

The Omega-6:Omega-3 Ratio: A Critical Appraisal and Possible Successor
There is a growing interest in exploring the relationships between fatty acid (FA) status and clinically important health outcomes [1]. These include cardiac disease [2 –4], stroke [5], diabetes [6], cognitive function [7], and aging [8–10]. However, analysis of FAs is much more complicated than it is for other biomarkers like cholesterol or glucose. The latter analytes circulate in plasma as single molecular species whose concentrations can be easily measured by long-ago standardized enzymatic methods, and optimal levels are clearly defined after decades of research, either as a risk factor for a disease [e.g., corona...

Omega-3 fatty acid supplement reduces activation of NADPH oxidase in intracranial atherosclerosis stenosis.
Conclusions Long-term O3FA dietary supplementation prevents the development of intracranial atherosclerosis. This O3FA effect appears to be mediated by its attenuation of NOX subunit expression and NOX activity, therefore reducing ROS production. O3FA dietary supplement shows promising results in the prevention of ICAS. PMID: 29576013 [PubMed - as supplied by publisher]

Natural approaches in metabolic syndrome management.
Authors: Patti AM, Al-Rasadi K, Giglio RV, Nikolic D, Mannina C, Castellino G, Chianetta R, Banach M, Cicero AFG, Lippi G, Montalto G, Rizzo M, Toth PP Abstract Metabolic syndrome (MetS) is characterized as a group of cardiometabolic risk factors that raise the risk for heart disease and other health problems, such as diabetes mellitus and stroke. Treatment strategies include pharmacologic interventions and supplementary (or "alternative") treatments. Nutraceuticals are derived from food sources (isolated nutrients, dietary supplements and herbal products) that are purported to provide health benefits, in addition ...

Polyunsaturated fatty acids for the primary and secondary prevention of cardiovascular disease.
CONCLUSIONS: This is the most extensive systematic review of RCTs conducted to date to assess effects of increasing PUFA on cardiovascular disease, mortality, lipids or adiposity. Increasing PUFA intake probably slightly reduces risk of coronary heart disease and cardiovascular disease events, may slightly reduce risk of coronary heart disease mortality and stroke (though not ruling out harms), but has little or no effect on all-cause or cardiovascular disease mortality. The mechanism may be via lipid reduction, but increasing PUFA probably slightly increases weight. PMID: 30019767 [PubMed - as supplied by publisher]
