New evidence supports eating seafood for its cardiovascular benefits

Organizations such as the Spanish Heart Foundation and the American Heart Association in the United States support the findings of numerous studies that have, for years, highlighted the importance of including aquatic products in the diet for cardiovascular health.

One of the main benefits, though not the only one, is that certain fish and seafood, many of which are farmed, are rich in omega-3 polyunsaturated fats, particularly EPA and DHA.

Recently, a new study, researchers from the Democritus University of Thrace in Greece have published in the journal Nutraceuticals, reveals new data on the powerful cardioprotective properties of certain foods classified by researchers as "functional," including fish such as salmon and sardines. According to the findings, these fish not only improve HDL cholesterol (high-density lipoproteins) levels but also enhance its functionality in the body.

The study provides additional evidence to reinforce what was already known: regular consumption of these aquatic products improves reverse cholesterol transport, a key process that helps remove cholesterol from the arteries and transport it to the liver for elimination. This mechanism reduces the risk of cardiovascular diseases, such as atherosclerosis, and helps prevent heart attacks and strokes.

Omega-3 fatty acids present in these foods also have anti-inflammatory and antioxidant properties that promote vascular health by reducing inflammation and oxidative stress, both critical factors in the development of heart disease. The study adds value to existing knowledge about the benefits of these foods, which in some cases surpass the effects of traditional pharmacological treatments by improving both the quantity and quality of HDL cholesterol.

In addition to fatty fish, fish oil emulsions, sold as omega-3 capsules, have also proven effective, according to the research. These emulsions improve anti-atherogenic HDL subfractions and reduce pro-atherogenic subfractions, offering better protection against cardiovascular disorders by preventing or reducing plaque formation in the arteries.

In summary, this new study strengthens recommendations to include omega-3-rich aquatic products in the diet, emphasizing their role not only in cholesterol regulation but also in the overall protection of the cardiovascular system.

For individuals concerned about heart health, foods such as salmon, trout, sea bream, sea bass, croaker, sole, turbot, and especially sardines and other fatty fish, emerge as a natural and effective option to reduce the risk of heart disease in a safe and preventive manner.
