Introduction

Fish consumption is associated with beneficial effects on a number of health outcome variables. The strongest evidence is the prevention of cardiovascular disease Fatty fish (e.g., salmon, mackerel, herring) are important dietary sources of marine omega-3 fatty acids (eicosapentaenoic acid; EPA and docosahexaenoic acid; DHA) fatty fish is also a source for other nutrients such as vitamin D, iodine, selenium and protein. Lansdowne and Provost found in a randomized double blind study that vitamin D supplementation during late wintertime enhanced positive affect and reduced negative affect. In a dietary intervention study during wintertime, fatty fish consumption had a positive influence on sleep and daily functioning, and sufficient vitamin D status was positively related to the beneficial effect emphasized heart rate variability (HRV) as one potentially useful outcome measure in relation to fish consumption. In a population-based study investigated the relationship among self-reported habitual fish intake, omega-3 consumption and different measures of HRV. HRV can be operationalized through a variety of measures such as time-domain (e.g., root mean square successive differences; rMSSD), respiratory sinus arrhythmia (RSA) and frequency-domain (high frequency (HF), low frequency (LF) and LF/HF-ratio), findings showed that Atlantic salmon consumption caused improvements in both HRV and HR, as well as reductions in state-anxiety in a sample of male forensic inpatients. Interestingly the results also demonstrated a relationship between vitamin D status and rMSSD at post-test even though neither of the groups was vitamin D deficient at any time point. However, the Control group had a suboptimal vitamin D status (for US population: <75 nmol/L) at post-test, while the vitamin D status in the Fish group was still close to the optimal level at post-test as described more thoroughly in Hansen et al. At pre-test there was a positive relationship between EPA and state-anxiety. However, this trend was not observed at post-test. The present results showed that fatty fish consumption caused changes in HRV which is regarded. As interestingly, the present long-term dietary fish intervention study was in line with who found a relationship between fish consumption and specific HRV components such as the rMSSD [1-6]. Additionally, the present 23 week study helps to clarify the finding of a previous investigation demonstrating that a fish intervention of only eight weeks was not sufficient to cause any change in rMSSD. Thus, longer interventions may be necessary to produce reliable effects. Importantly, the result from the self-reported anxiety measure was in line with the biological objective measure of anxiety. The current results demonstrated that Atlantic salmon consumption caused a significant decrease in state-anxiety, but not trait-anxiety.

Material and Methodology

This extends previous research investigating the relationship between fish consumption and depression. The state-anxiety is characterized by physiological arousal and it has been argued that the state-anxiety scale involves elements of both emotional-autonomic activation and cognitive worry. The STAI is a well validated instrument and previous studies have also demonstrated that the state-anxiety scale is sensitive to interventions such as a single session of slow breathing. Thus, the present results suggest that state-anxiety may also be sensitive to nutritious food intervention. The lack of a significant reduction in the trait-anxiety scale in the present study may be because trait-anxiety is associated with more stable personality traits and a\ stable individual vulnerability to experience anxiety. As such, trait-anxiety may be more difficult to change during a 6 month intervention study.

The present study demonstrated that Atlantic salmon consumption had beneficial effects on HRV measured as rMSSD, HR and state-anxiety. If this is solely a vitamin D effect, a routine vitamin D supplementation could be adequate. However, fatty fish contributes several other essential nutrients such as marine omega-3, iodine, selenium, and proteins, and increased seafood consumption may also substitute for other meals with a lower nutritional value.
