Psychological distress often appears as a tightly linked cluster of high stress, anxiety, low mood, poor sleep, and everyday memory lapses. While omega-3 fatty acids are known to support brain structure and signaling, evidence for their mental health effects remains inconsistent across populations. A randomized, double-blind, placebo-controlled trial followed 64 young adults who reported severe psychological distress. Participants were randomly assigned to take either an omega-3 capsule or a placebo capsule made with corn oil for 12 weeks. The research team measured several aspects of mental h... anxiety depression omega-3 stress
Read moreWhen a tooth infection spreads to the root, the body's immune response can become overly aggressive, destroying surrounding bone and tissue. Scientists at São Paulo State University tested whether two accessible lifestyle factors, swimming and omega-3 fatty acids, could reduce this damage. Thirty male rats were divided into three groups: an exercise‑only group, a group that combined exercise with omega-3 supplementation, and a control group without exercise or omega-3 supplementation. The exercising rats swam for an hour a day, five days a week, for six weeks. The combined group also received... exercise omega-3 dental
Read moreHip fractures can lead to a decline in self-reliance, diminished quality of life, and feelings of depression. However, some research suggests that consuming fish and omega-3 fatty acids influences a person's risk of experiencing a hip fracture. A 2019 meta-analysis and systematic review found that higher fish and omega-3 intake reduces the risk of hip fracture by as much as 12 percent. Researchers reviewed the findings of 10 studies involving nearly 300,000 people. Seven of the studies followed people over time (prospective), and three compared groups with and without fractures (case-control).... diet aging omega-3 bone
Read moreLipid rafts – cholesterol-filled "bubbles" found in neuronal cell membranes – play a crucial role in synaptic plasticity and memory formation. However, lipid rafts undergo extensive changes during aging, ultimately contributing to cognitive decline. A new study in mice shows that omega-3 fatty acids preserve lipid raft integrity and bolster cognitive function. Researchers fed young and old female mice a regular diet or a diet supplemented with omega-3 fatty acids. Then they examined the animals' brains to determine the omega-3s' effects on the structure and properties of the lipid rafts. They... aging omega-3 memory
Read moreOmega-3 fatty acids improve aspects of heart failure. More than 26 million people worldwide currently live with heart failure, a serious condition characterized by diminished capacity of the heart’s ventricles to fill with or eject blood and cardiomyocyte death. Adaptive responses to heart failure induce ventricular remodeling – structural and functional accommodations of the left ventricle that hinder contractility and impair ventricular filling. Findings from a recent systematic review and meta-analysis suggest that omega-3 fatty acids improve aspects of left ventricular remodeling in peopl... heart disease omega-3
Read moreDementia is a large and growing health concern facing older adults, with approximately 15 to 20 percent of people aged 65 years and older living with mild cognitive impairment. Omega-3 fatty acids have benefits for those with mild cognitive impairment and coronary artery disease, a risk factor for dementia because it restricts blood flow to the brain. Findings of a recent report demonstrate the effects of omega-3 supplementation on cognitive decline in cognitively healthy older adults with coronary artery disease. The omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic aci... brain heart disease omega-3 supplements
Read moreDiets rich in omega-3 fatty acids have been shown to decrease the risk of Alzheimer’s disease. A growing number of studies have also demonstrated the benefits of omega-3 supplementation in adults with dementia. Authors of a recent report investigated the effects of omega-3 supplementation in adults without cognitive decline. Both eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the two main forms of omega-3 fatty acids, suppress inflammation, regulate neurogenesis, decrease oxidative stress, and protect the aging brain. Previous research (https://pubmed.ncbi.nlm.nih.gov/23796946/) h... brain omega-3
Read moreDNA damage, a major contributor to aging, occurs from exposure to byproducts of cellular metabolism, environmental chemicals, and radiation from sunlight. If not repaired, DNA damage can be detrimental and is associated with diseases such as cardiovascular disease and cancer. A new study suggests that higher levels of omega-3 fatty acids are associated with lower DNA damage in children and adolescents. Omega-3 fatty acids are essential because the body cannot make them, and they must be obtained from the diet. They include eicosapentaenoic acid, or EPA, and docosahexaenoic acid, or DHA. EPA an... omega-3 dna damage
Read moreParenteral nutrition (PN) is the intravenous feeding of a person whose gastrointestinal tract is not working. Findings presented in a recent review and meta-analysis suggest that enriching the PN solution with omega-3 fatty acids improved patient outcomes and reduced the length of hospital and ICU stays. Omega-3 fatty acids are long-chain polyunsaturated fatty acids, considered essential because the human body cannot make them. Conventional lipid emulsions used in PN, including soybean and safflower oils, are high in omega-6 fatty acids, which can increase inflammation and suppress the immune ... omega-3
