Fish is an important source of nutrients, especially omega-3 fatty acids, which can reduce the risk of cardiovascular and autoimmune diseases, cancer, and mental disorders. However, some fish can contain high levels of mercury and other contaminants. It is advisable to choose sustainable fish and limit the consumption of predatory fish to no more than two servings per week.
Fish and cardiovascular diseases
Cardiovascular disease is one of the leading causes of death worldwide, characterized by the buildup of plaque in the arteries that can cause heart attacks and strokes. Diet and lifestyle are known to play an important role in the prevention of cardiovascular disease, and studies have shown that regular intake of fish can reduce the risk of cardiovascular disease.
Fish is a rich source of omega-3 fatty acids, a type of polyunsaturated fat found in high concentrations in the tissues of certain fish such as salmon, trout, herring, and mackerel. Omega-3 fatty acids have anti-inflammatory effects and can help lower blood triglyceride levels, which can reduce the risk of cardiovascular disease.
A 2018 review study published in the journal Nutrients evaluated the relationship between omega-3 fatty acid intake and the risk of cardiovascular disease. The authors concluded that the intake of omega-3 fatty acids is associated with a significant reduction in the risk of cardiovascular diseases, including coronary heart disease and stroke. Another study published in the American Journal of Clinical Nutrition found that fish intake was associated with a 15% reduction in the risk of cardiovascular disease.
In addition to omega-3 fatty acids, fish is a good source of high-quality protein, essential vitamins, and minerals. Fish protein is rich in essential amino acids, which are important for tissue growth and repair. Fish is also rich in vitamins and minerals, including vitamin D, selenium, and calcium, which are important for bone health and cell function.
For the greatest health benefits, it is recommended to consume at least two servings of fish per week, and choose fish rich in omega-3 fatty acids such as salmon, trout, herring, and mackerel.
