Brief Summary

There is sufficient evidence on the beneficial effects of fish consumption on health, mainly associated with the content of omega-3 polyunsaturated fatty acids (EPA and DHA) present mainly in blue fish. Different national and international organizations have issued recommendations on the optimal amount of fish that the population should consume to prevent certain chronic diseases related to diet. Thus, the WHO recommends eating fish regularly (1-2 servings per week for healthy adults) to ideally provide the equivalent of 250 mg of omega-3 fatty acids (EPA + DHA). Not reaching the optimal levels of EPA + DHA increases the risk for cardiovascular diseases, increasing the risk of death according to certain epidemiological studies. In this sense, using more precise techniques such as membrane lipidomics, allow adequate quantification and monitoring of fatty acid levels present in our body and how this lipid profile can change according to metabolism and diet. The objective of this study is to carry out a clinical trial of nutritional intervention with an adult population without pathologies that has a low consumption of fish (\<2 servings / week) to evaluate the effectiveness of an intervention strategy based on increasing the number of fish servings through a controlled intake of fresh and canned fish. The results aim to show that increasing fish intake has an impact on lipid metabolism and in the future, for the prevention of certain chronic diseases, the introduction of canned fish can be a healthy strategy to increase fish consumption to long term.

Outcome Measures

Primary Outcomes (1)

  • Metabolic status: RBC membrane fatty acid profile.

    Twelve fatty acids will by analyzed as representative cluster of the main building blocks of the red blood cell (RBC) membrane glycerophospholipids (palmitic acid, stearic acid, palmitoleic acid, oleic acid, cis-vaccenic acid, eicosapentaenoic acid, docosahexaenoic acid, linoleic acid, dihomo-gamma-linolenic acid (DGLA), arachidonic acid (AA) and two geometrical trans fatty acids (trans elaidic acid and mono-trans arachidonic acid isomer). The amount of each fatty acid will be calculated as a percentage of the total fatty acid content in the red blood cell membrane (relative %). Omega 3 index (EPA+DHA) as a biomarker of cardiovascular risk and omega-6/omega-3 ratio as biomarker of inflammatory status will be the main outcomes. Investigators will take into accounts the optimal ranges of each of the 12 fatty acids in red blood cell membranes previously reported in the literature (Ferreri C et al. 2012. Expert Rev. Mol. Diagn. 12(7), 767-780).

Study Arms (2)

Group A: Fresh/frozen fish

EXPERIMENTAL

Healthy diet based on mediterranean guidelines with specific recommendation of fish intake (3-4 servings/week of fresh or frozen fish or shellfish), excluding the consumption of canned fish.

Behavioral: nutritional guidelines to promote healthy diet and increase fish intake

Group B: Canned fish

EXPERIMENTAL

Healthy diet based on mediterranean guidelines with specific recommendation of fish intake (3-4 servings/week of fresh or frozen fish or shellfish where at least 1-2 servings will be in the form of canned fish). A selection of canned fish (tuna, sardine, salmon and mackerel) will be administered to each volunteer for the duration of the study.

Behavioral: nutritional guidelines to promote healthy diet and increase fish intake

Interventions

Nutritional guidelines based on the Mediterranean diet will be provided to both groups (gropu A and group B) through infographic material, recipes and menus. Both groups will be guided to increase their fish consumption to 3 servings per week. Group A will do that through the consumption of fresh or frozen fish and group B through fresh, frozen and canned fish.

Group A: Fresh/frozen fishGroup B: Canned fish
