Increased intakes of omega-3 fatty acids may reduce heart rate reactivity to mental stress, a new US study suggests.
In the randomized controlled trial, 67 participants with normal blood pressure who received either a 9-gram fish oil supplement (with 1.6 grams of eicosapentaenoic acid and 1.1 grams of docosahexaenoic acid) or a placebo every day for eight weeks were submitted to a five-minute mental stress protocol both at the start of the study and eight weeks later (1). The study results showed that the participants who had taken omega-3 fatty acids had reduced increases in heart rate and muscle sympathetic nerve activity related to mental stress situations in comparison to the placebo group.
The researchers commented that the data supported and expanded the growing body of evidence that fish oil may have positive health benefits regarding neural cardiovascular control in humans. The potential efficacy of omega-3 fatty acids in reducing the ability of (long-term) psychological stress to damage health may help prevent the onset or progression of cardiovascular disease. Future studies might examine the influence of longer-term fish oil supplementation on neural cardiovascular reactivity to mental stress, with a particular focus on aged and/or diseased populations.

Until now, recommendations for adequate nutrition could only be generalized, or at best specialized for target groups like children, sportsmen and -women or the elderly. In contrast, personalized nutrition aims to define dietary recommendations and possibly appropriate products for each individual based on their genetic and physiological characteristics. These recommendations would be designed to maintain health and avert the disease risks to which that individual might be predisposed. Micronutrients are involved in specific biochemical processes at all points in the metabolic process and play an important role in regulating health and in the onset of diseases. New analytical techniques make it possible to examine and describe the influence of micronutrients in health-preserving processes. This is usually done by analyzing a combination of biomarkers so as to provide the individual with a tailored micronutrient intake recommendation.
