Sardines, being an affordable source of Omega-3 and other cardioprotective nutrients, can potentially reduce the need for Omega-3 supplementation and manage cardiometabolic diseases.
The abstract primarily acknowledges the importance of Omega-3 polyunsaturated fatty acids with respect to managing diseases related to heart health and metabolism, for instance, type 2 diabetes, hypertension, hypertriglyceridaemia, and fatty liver disease. However, these fatty acids are not the sole beneficial component of sardines. Minerals including but not limited to calcium, potassium, and magnesium as well as substances like taurine and arginine found in sardines have a significant role in controlling mild inflammation and oxidative stress which are usually present in cardiovascular diseases and hemodynamic dysfunction.
The results discussed in the abstract suggest a positive correlation between consumption of sardines and potential cardiometabolic benefits. By considering the dose-response relationship effects, a pragmatic approach towards consumption of nutrients was suggested. The intake of sardines was seen not only as a means of Omega-3 supplementation but also as a comprehensive approach to enhancing cardiovascular health. The abstract concludes with an emphasis on the many beneficial nutrients found in sardines besides Omega-3, underlining the need to shift the focus from synthetic supplementation to natural dietary improvement.

2023 Nutrients Exploring the Potential Benefits of Natural Calcium-Rich Mineral Waters for Health and Wellness: A Systematic Review Pop MS, Cheregi DC, Onose G, Munteanu C, Popescu C, Rotariu M, et al.
Systematic Review Bone Health Calcium Cardiovascular Disease
This systematic review analyzed peer-reviewed articles, clinical trials, and experimental studies from the past decade. It focused on the health benefits of calcium-rich mineral waters, especially for individuals with lactose intolerance or on plant-based diets. The review process assessed the contribution of these waters to daily calcium intake and their bioavailability compared to other calcium sources.
The review found that natural mineral waters high in calcium can significantly enhance calcium intake, with improved absorption rates. These waters show promise in promoting bone health and cardiovascular function, including potential reductions in blood pressure and cardiovascular disease risk. Some evidence suggests benefits in weight management. However, the review highlighted the need for further research on interactions with other dietary components, effects on specific health conditions, and long-term consumption impacts. Despite these gaps, calcium-rich mineral waters are recognized as a valuable dietary calcium source for a diverse population.

Review Article Almond Cardiovascular Disease Cognitive Function
The methodology employed in this study included analyzing a range of clinical studies centered on the health benefits linked to the consumption of sweet almond nuts. Various health outcomes correlated with almond consumption were investigated such as body weight, food intake, blood pressure, blood lipid composition, glucose and insulin levels, oxidative status, liver enzymes, and some inflammation biomarkers.
The discussion of the results reveals that almond consumption has been found to create favorable alteration in aspects like body weight, food intake, blood pressure, blood lipid composition, glucose, and insulin levels, as well as oxidative status, liver enzymes, and inflammation biomarkers. These findings highlight the beneficial impact of almonds on multiple health issues including cardiovascular diseases, diabetes, and obesity. Additionally, the consumption of almonds has been associated with improved cognitive performance and protection against skin photodamage and aging.
Nutrition, particularly an anti-inflammatory Mediterranean diet supplemented with oily fish and omega-3 supplements, can potentially reduce inflammation and improve symptoms of rheumatoid arthritis.
2023 Autoimmunity Reviews Nutrition and its role in prevention and management of rheumatoid arthritis Nikiphorou E, Philippou E
Review Article Mediterranean Diet Omega-3 Fatty Acids Sardine
The review examines evidence indicating a possible connection between nutrition and the risk and management of rheumatoid arthritis, an autoimmune disease having an immune-inflammatory response. The impact of different food types was considered, including pro-inflammatory and anti-inflammatory foods. Specifically, the research highlights the effectiveness of a Mediterranean diet, rich in fish and supplemented with omega-3 polyunsaturated fatty acids, in reducing inflammation and oxidation. Other factors such as herbs and spices, beverages, vitamin D, and probiotics were also taken into account. The research emphasizes the direct and indirect role of nutrition through the management of co-morbidity.
The disease activity was observed to improve with dietary changes, particularly a propensity to reduce inflammation, oxidation, and beneficial effects on gut microbiota. An anti-inflammatory Mediterranean diet, supplemented with consumption of oily fish at least twice a week, and daily intake of omega-3 polyunsaturated fatty acid supplements of 2 g, has been recommended. The study also highlights the importance of rheumatologists working closely with registered dietitians to support patients in managing a well-balanced diet according to their individual needs.
Honey intake has observed beneficial effects on various health aspects like cardiovascular, metabolic risk factors, and wound healing, primarily replacing other sweeteners.
2023 Nutrients A Comprehensive Review of the Effect of Honey on Human Health Palma-Morales M, Huertas JR, Rodríguez-Pérez C
Review Article Cardiovascular Disease Honey Wound Healing
In this comprehensive review study, the researchers went beyond just looking at one or two aspects of health; instead, they embarked on an ambitious task of reviewing forty-eight clinical trials that were published between 1985 and 2022, involving a total of 3655 subjects. The researchers aimed to critically analyze the effect of honey on multiple health indices, including, but not limited to, cardiovascular and metabolic risk factors, glucose tolerance, mucositis inflicted by chemo-radiotherapy, cough in children, and wound healing.
The evaluation and analysis of the data involved a thorough examination of the results of each of the clinical trials, consideration of several potential variables, and detailed cross-study comparisons. This broad and deep investigation allowed the researchers to draw correlations and pinpoint the beneficial influences of honey, considered a nutritious and natural food.
The results from these clinical trials saw more beneficial effects on health from honey intake when compared to neutral or negative outcomes. It was most notably effective, particularly when used as a substitute for other sweeteners. The review also pointed out the potential use of honey as a safe adjuvant to be used in combination with drugs for specific illnesses. Confidently stating that honey has clear benefits in the clinical trials analyzed, the researchers fostered a promising narrative for the further exploration and acceptance of honey as a health booster.

An excellent review article highlighting the benefits of this very underappreciated yet highly nutritious fish. For example, the calcium content in 100 g of sardines is equivalent to the amount found in ~ 400 ml of milk (38% of the recommended dietary allowance). Sardines also contain a considerable amount of iron (2.9 mg/100 g) comparable to that of meat and higher than other commonly consumed types of fish.
