A study confirms that certain compounds in salmon act on the body and improve cardiometabolic health.
- American researchers have identified the specific salmon compounds (FSC), present in the body when consumed. They counted 508 CBFs with 237 unique metabolites.
- After regular consumption of salmon, the levels of 48 FSCs and 30 metabolites, present in the blood, increased significantly.
- Increases in two CBFs and two metabolites were associated with improvements in total cholesterol, bad cholesterol, triglycerides, and apolipoprotein B.
Protein, omega 3, vitamin D and E… THE Salmon contains many nutrients essential for the proper functioning of the body. Nutritionists and dieticians do not hesitate to recommend it to people suffering from heart and metabolic diseases or simply to those wishing to lose weight.
Researchers from the University of Colorado wanted to better measure its impact on the body. To do this, they called on the nutrimetabolomics. This approach relies on comprehensive analysis of food and human biological samples to identify biomarkers of food intake (or specific compounds) and determine their impacts on health.
Salmon : fish-specific compounds found in blood
For this work presented in the journal Journal of Nutritionthe scientists brought together 41 participants. They had to follow a Mediterranean diet including two servings of salmon per week for two five-week periods. Blood tests were performed before and after the trials.
The researchers also carried out tests to determine the specific compounds in fish. (FSC) compared to the 99 foods from Mediterranean cuisine. They counted 508 FSC with 237 unique metabolites (organic substances from a food) for this dish. Of these, 143 FSC and 106 metabolites were found in plasma. Additionally, scientists have noticed that levels of 48 FSC and 30 metabolites increased in the blood after regular salmon consumption.
Cholesterol, triglycerides: lsalmon improves health cardiometabolic
The team wanted to determine the effects of these elements, whose levels had increased in the blood, on the body. Through her analyses, she discovered that increases of two FSC and two metabolites, from salmon, were associated with improvements in health indicators cardiometabolic.
More specifically, in people who had these four compounds from salmon in their blood, the researchers noted reductions in the level of total cholesterol, cholesterol LDL (bad cholesterol)triglycerides and apolipoproteins B (a high level of this protein increases the risk of suffering from diseases cardiovascular).
The scientists note that if their findings are confirmed by other work, the specific compounds in the foods – identified through nutrimetabolomics – could “serve, after subsequent validation, as biomarkers or act as bioactive components influencing health”.
