Recent studies have shown that certain foods, such as caffeine and sugar, can cause a rapid increase in heart rate, while others, such as omega-3 fatty acids, can have a calming effect. This leads to the question: Can the food we eat affect our heart rate? This research explores the relationship between food and heart rate and its potential impact on our overall health. The idea that must be tested is if the food people eat can significantly impact heart rate and should be considered as a factor in maintaining a healthy heart. In the following annotated bibliography, two sources that address this topic will be examined and evaluated on their relevance, reliability, and timeliness. In addition, the gathered information will be assessed for how it will be used further in the study. The data presented in the analyzed articles allow researchers to trace a clear relationship of diet to the functioning of the human circulatory system.
Young, H. A., & Benton, D. (2018). Heart-rate variability: A biomarker to study the influence of nutrition on physiological and psychological health? Behavioural Pharmacology, 29, 140-151.
The article “Heart-Rate Variability: A Biomarker to Study the Influence of Nutrition on Physiological and Psychological Health?” by Young and Benton provides valuable insights into the relationship between nutrition and heart rate. The authors use heart-rate variability (HRV) as a biomarker to study the effects of food on physical and mental health. The article was published by experienced researchers in a peer-reviewed journal, “Behavioural Pharmacology,” which means it has high credibility. The authors used a standardized, objective, and reliable method for measuring the impact of nutrition on heart rate (Young & Benton, 2018). The source was published in 2018, which reflects current knowledge and makes it timely and relevant.
The research “Heart-Rate Variability” will be used in the introduction to provide context for our argument and to establish the scientific basis for our research. The authors conclude that HRV can operate as an indicator of the effects of nutrition on the autonomic nervous system, which can be used as evidence to support the research argument (Young & Benton, 2018). The statistical indicators obtained by the authors of this work will serve as evidence of the significance of the HRV indicator in establishing the relationship between food intake and heart rate.
Chapman, C. L., Reed, E. L., Worley, M. L., Pietrafesa, L. D., Kueck, P. J., Bloomfield, A. C. & Johnson, B. D. (2021). Sugar-sweetened soft drink consumption acutely decreases spontaneous baroreflex sensitivity and heart rate variability. American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 320(5), R641-R652.
The article “Sugar-sweetened soft drink consumption acutely decreases spontaneous baroreflex sensitivity and heart rate variability” by Chapman et al. is dedicated to providing a link between high fructose corn syrup (HFCS) consumption and HRV. The study results show that consuming sugar-sweetened soft drinks decreases HRV, an essential indicator of heart health (Chapman et al., 2021). The article was published in 2021 in a peer-reviewed journal, “Americal Journal of Physiology-Regulatory, Integrative, and Comparative Physiology.” The authors conducted a controlled study that provides a standardized and objective measuring method. Therefore, the source has high levels of credibility, reliability, and timeliness.
The article by Chapman et al. will be included in the body of the paper and provide concrete evidence of sugar-sweetened soft drinks’ impact on heart rate. This study confirms the connection between certain product consumption (HFCS) and increased HRV. Thus, this source will be used to support the argument that consuming sugar-sweetened soft drinks can have a negative impact on heart rate. The findings of this study will be used to illustrate how specific types of food can affect heart rate, making it an important addition to the overall argument of the research paper.

This study examines the relationship between the effect of food intake on heart rate based on HRV and through the lens of the nervous system. The author, in a paper published in 2022 in Applied Sciences, describes the mechanism of the effect of nutrients entering the bloodstream on the specificity of nerve impulse passage as part of heart function (Hayano et al., 2020). Along with the researchers of the previous two articles, the scientist relies on HRV as the most important biomarker of the circulatory system. The data studied in this paper will be included in a separate section of the theoretical part, looking at the hypothesis from the perspective of the nervous system. This will help to show how nutrition manifests itself at the smallest levels of blood cell function.
