Omega-3 fatty acids are elements found in diet (or supplements) that help the body grow and maintain its health. They're essential for the structure of every cell wall. They also serve as an energy source and aid in the proper functioning of your heart, lungs, blood vessels, and immune system. Seafood, such as fatty fish (such as salmon, tuna, and trout) and shellfish, include the omega-3 fatty acids EPA and DHA (e.g., crab, mussels, and oysters). Other foods, such as some vegetable oils, include ALA, a distinct kind of omega-3 (e.g., canola and soy).
Health Benefits of Omega-3 Fatty Acids
Blood fat (triglycerides): Triglyceride levels can be lowered using fish oil. You're at risk for heart disease and stroke if you have excessive levels of this blood fat.
According to a 2012 assessment of the scientific literature, the omega-3s EPA and DHA, which are present in seafood and fish oil, may be somewhat useful in reducing rheumatoid arthritis symptoms. Many of the participants in the trials included in the analysis reported having less morning stiffness, less joint swelling and pain, and less need for anti-inflammatory medicines to regulate their symptoms when they took fish oil.
Seafood's nutritional value is particularly crucial throughout prenatal development, as well as early infancy and childhood. As part of a healthy eating pattern and while maintaining within their calorie needs, pregnant or breastfeeding women should consume 8 to 12 ounces of seafood per week from a variety of low-methylmercury fish kinds. Women who are pregnant or nursing should consume no more than 6 ounces of white tuna (also known as "albacore") each week. Tilefish, sharks, swordfish, and king mackerel are rich in methyl mercury and should be avoided.
Asthma: Inflammation, which is a critical component of asthma, is reduced by eating a diet rich in omega-3 fatty acids. However, further research is needed to determine whether fish oil supplements enhance lung function or reduce the quantity of medication required to manage the illness.
ADHD: According to research, fish oil can help certain children with ADHD symptoms by improving their mental functions such as thinking, remembering, and learning. More research is needed, and omega-3 supplements should not be used as first-line therapy.
Dementia and Alzheimer's disease are two conditions that affect people. Omega-3 fatty acids may help protect against Alzheimer's disease and dementia, as well as have a positive effect on ageing-related memory decline, according to some studies. However, this is not yet definite.
