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.
2023 Frontiers in Nutrition Eating more sardines instead of fish oil supplementation: Beyond omega-3 polyunsaturated fatty acids, a matrix of nutrients with cardiovascular benefits Santos HO, May TL, Bueno AA
Review Article Cardiovascular Disease Cholesterol High Blood Pressure
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.
Consumption of blueberry powder daily improves vascular function, cognitive abilities, and reduces blood pressure in healthy older individuals.
2023 The American Journal of Clinical Nutrition Wild blueberry (poly)phenols can improve vascular function and cognitive performance in healthy older individuals: a double-blind randomized controlled trial Wood E, Hein S, Mesnage R, Fernandes F, Abhayaratne N, Xu Y, et al.
Randomised Controlled Trial Blueberry Cardiovascular Disease Cognitive Function
This double-blind, parallel randomized controlled trial engaged 61 healthy older individuals aged between 65 to 80 years old. Participants were given either 26g of freeze-dried wild blueberry (WBB) powder, comprising 302 mg anthocyanins, or a similar placebo with zero mg anthocyanins. Measurements were made for endothelial function, cognitive function, arterial stiffness, blood pressure, cerebral blood flow, gut microbiome, and blood parameters, both at the start of the trial and again following 12 weeks of daily consumption. In addition, plasma and urinary polyphenol metabolites were analyzed through the use of microelution solid-phase extraction combined with liquid chromatography-mass spectrometry.
In the WBB group, there was a notable increase in endothelial function and a decrease in 24-hour ambulatory systolic blood pressure, when compared to the placebo group. Enhanced immediate recall on the auditory verbal learning task was also observed, along with better accuracy on a task-switch task following administering of WBB. Notably, the total 24-hour urinary excretion of polyphenols also significantly increased in the WBB group comparative to the control group. In contrast, there were no discernible changes in cerebral blood flow or gut microbiota composition. These findings imply that WBB polyphenols could contribute to reducing future cardiovascular disease risk in older populations, and might enhance memory processes and executive functioning in older adults at risk of cognitive decline.
Coconut water possesses unique compound profiles that imbue it with a broad spectrum of medical properties, incorporating aspects of nutrition, pharmacology, and disease prevention.
2022 Reference Series in Phytochemistry Health Benefits of Coconut Water Rethinam P, Krishnakumar V
Review Article Alzheimer's Disease Cardiovascular Disease Coconut Water
The study utilized comprehensive analysis to assess the chemical profile of coconut water, identifying a range of components including phytohormones, enzymes, antioxidant compounds, vitamins, minerals, and phenolic compounds. These components are known to contribute to the water's biological activity and pharmacological effects, thereby enabling a raft of medicinal properties inherent to coconut water. The water was found to feature anti-microbial, anti-bacterial, anti-inflammatory, anti-hypertensive, rejuvenating, hepatoprotective, hypolipidemic, and diuretic properties.
An examination of the therapeutic effects of coconut water revealed a significant impact on gastric dysfunction, dysentery, and child malnutrition alongside notable capabilities to manage hypertension. The water was found to promote exercise performance, reduce swelling, dissolve kidney stones, improve kidney function, improve digestion, relieve constipation, reduce the risk of heart disease, lower high blood pressure, and improve cholesterol levels. Consumption of tender coconut water was specifically found to reduce the risk of heart disease, help prevent Alzheimer’s disease pathologies and prevent osteoporosis in experimental animals. The unique nutritional profile of coconut water was also found to provide it with the capacity to balance body chemistry and fight cancer.
Pomegranate extract consumption improves antioxidant levels, reduces oxidative stress and cardiovascular risk factors including blood pressure and body fat, and increases lean body mass.
2022 Antioxidants Antioxidant Properties and Beneficial Cardiovascular Effects of a Natural Extract of Pomegranate in Healthy Volunteers: A Randomized Preliminary Single-Blind Controlled Study Al-Dujaili EAS, Casey C, Stockton A
Randomised Controlled Trial Cardiovascular Disease High Blood Pressure Pomegranate
In the study, 24 healthy participants were divided into two groups: one consumed a natural standardized pomegranate extract, while the other, a placebo, in a randomized, single-blind placebo-controlled trial. Evaluations were conducted at baseline and post 14 and 28 days of the experiment, with variables including anthropometric measurements, blood pressure, pulse wave speed, body composition, as well as the levels of salivary and urinary cortisol, cortisone, total phenolics, antioxidant capacity, and lipid peroxidation.
The results indicated significant increases in urinary total phenolics excretion and antioxidant capacity after 14 and 28 days of pomegranate extract intake. By day 28, notable decreases were noted in systolic and diastolic blood pressure, pulse wave velocity, body fat and fat mass, and an increase in lean body mass. In terms of glucocorticoid levels, there was a marked decrease in saliva cortisol at day 28 in the morning for the pomegranate extract group, along with a decrease in the cortisol/cortisone ratio following 28 days of pomegranate extract intake at morning, noon, and evening. Reductions were also seen in urine free cortisol levels by day 14. These observations were unique to the pomegranate extract group, with no significant changes noted in the placebo group.
The literature overall supports an inverse association between green tea and cardiovascular disease-related health outcomes, while the included meta-analyses generally suggested an inverse association between green tea and BMI-related and blood pressure outcomes.
2020 European Journal of Clinical Nutrition Green tea and cancer and cardiometabolic diseases: a review of the current epidemiological evidence Abe SK, Inoue M
Systematic Review Cancer Cardiovascular Disease Endometrial Cancer
The evidence on green tea consumption and health outcomes presented in this review suggests green tea may be favorable for cardiovascular disease, particularly stroke, and certain cancers such as endometrial, esophageal, lung, non-Hodgkins lymphoma, oral, and ovarian cancer. More evidence is needed to assess the impact of green tea on breast, gastric, and liver cancer risk. Additional studies could also help clarify the suggested null association with certain cancer sites: colorectal, pancreatic, and prostate cancer. Possible minor adverse events on health from green tea consumption were reported in one study, however these must be interpreted cautiously within the study context and possible finer dose-response implications. The findings for green tea and diabetes risk were inconclusive. For BMI the current evidence suggests a possible weak association, while the evidence is stronger supporting a decrease in blood pressure from green tea. More studies investigating a possible association between green tea consumption and other health outcomes such as cognition, injuries, respiratory disease would be informative to more completely assess the impact of green tea on human health.
In conclusion, our review suggests green tea may have health benefits especially for cardiovascular disease and certain cancer sites.
