Almond intake significantly decreased diastolic blood pressure, and inconsistently, almonds decreased systolic blood pressure.
The evidence from this meta-analysis suggest that almonds may have beneficial effects on the BP. Based on the current scientific knowledge, it could be encouraged to include them, as part of a healthy diet in order to reduce the risk of hypertension.66 It should be noted that results cannot be generalized to those with other health problems, such as liver disease and cancer that were not included in this analysis.
We found that almonds might have a considerable favorite effect in BP and especially in DBP, and it could be encouraged as part of a healthy diet; however due to the high calorie content, the intake should be part of healthy diet.

Natural calcium-rich mineral waters offer a bioavailable calcium source, beneficial for bone health, cardiovascular function, weight management, and overall well-being.
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 High Blood Pressure
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.
Consuming a honey-based gel, such as 'Bear Strength honey gel,' led to a notable reduction in diastolic and mean arterial blood pressure, with gender-specific improvements in redox status among healthy adults.
2023 Biomedical Reports Evaluation of the effects of a honey‑based gel on blood redox biomarkers and the physiological profile of healthy adults: A pilot study Patouna A, Sevdalis P, Papanikolaou K, Kourti M, Skaperda Z, Jamurtas A, et al.
Clinical Study High Blood Pressure
The study included 20 healthy participants (10 men, 10 women) who incorporated 70g of 'Bear Strength honey gel' into their daily diet for 14 days. Physiological parameters (weight, height, BMI, body fat, waist-to-hip ratio, resting heart rate, and blood pressure) and hematological data were evaluated before and after consumption. Redox biomarkers, including Glutathione (GSH), catalase (CAT), total antioxidant capacity (TAC), protein carbonyls (PCARBS), and thiobarbituric reactive substances (TBARS), were measured.
Post-consumption, the honey-based gel showed a significant decrease in diastolic and mean arterial blood pressure, particularly in women. However, no significant changes were observed in other physiological or hematological variables. Notably, GSH levels increased in both genders, TAC increased universally, and TBARS levels decreased in the total group and women. PCARBS levels decreased exclusively in the women's group. These findings highlight the honey-based gel's potential positive impact on blood pressure and redox status, emphasizing gender-specific effects in healthy adults.
Heavy coffee consumption increases the risk of cardiovascular disease mortality in individuals with severe hypertension, while green tea consumption does not.

Cohort Study Green Tea High Blood Pressure
With the use of the Japan Collaborative Cohort Study, researchers assessed 18,609 participants, both male and female, aged between 40 to 79 years. These participants had varying blood pressure levels, categorized into optimal and normal BP, high-normal BP, and two stages of hypertension. They completed a questionnaire about their lifestyle, diet, and medical history, and underwent health examinations, which were followed up until 2009. The association of coffee and green tea consumption on cardiovascular disease mortality was then calculated using a Cox proportional hazard model.
It was found over an 18.9 year follow-up period that heavy coffee consumption was linked to increased risk of cardiovascular disease mortality among those suffering from the second to third grade of hypertension. In stark contrast, people with optimal and normal, high-normal blood pressure and first grade hypertension did not show such associations between coffee consumption and cardiovascular disease mortality. Interestingly, the risk of cardiovascular disease mortality was not found to be increased across any blood pressure categories in relation to green tea consumption.
Almond consumption can significantly reduce the serum concentration of the inflammatory mediator, Interleukin-6, in adults but no significant effect is found on C-reactive protein.
2023 Complementary Therapies in Medicine A systematic review and meta-analysis of almond effect on C-reactive protein and interleukin-6 in adults Hariri M, Amirkalali B, Baradaran HR, Gholami A
Systematic Review Almond CRP IL-6
The methodology of this study involved running an electronic search for English-language studies across several databases such as Web of Science, PubMed, SCOPUS, ClinicalTrials.gov, and Cochrane library without any time restrictions. The effect sizes on serum concentration of C-reactive protein (CRP) and Interleukin-6 (IL-6) were calculated based on the mean changes of both intervention and control groups. Assessment of the overall effects and their heterogeneity was done using the DerSimonian and Laird random-effects model. To examine the statistical heterogeneity, Cochran's Q test and I-squared statistic were utilized.
With respect to the results, among the eleven studies involved, it was observed that almond consumption did not significantly affect serum CRP level. However, a significant decrease in serum IL-6 level was reported with almond consumption. Thus, reflecting the beneficial effects of almonds with regard to reducing the serum concentration of IL-6. The results derived for serum CRP were not substantial enough to be considered significant.
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
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.
