“…A 25% increase in plasma NO 3 − is considered to be a critical threshold for physiological impact [ 77 ]. Congruent with our observations, past human studies consistently demonstrate that BRJ supplementation raises plasma NO 3 − [ [78] , [79] , [80] , [81] , [82] , [83] ]. Further, BRJ lowers brachial BP in those with [ 45 , 78 , 84 , 85 ] and without hypertension in most [ 79 , 80 , 82 , 84 , 86 , 87 ], but not all [ 81 ] studies.…”

“…However, in a group of healthy elderly subjects (67 years), the consumption of 150 g of beetroot and a medium-sized banana every day for eight weeks reduced their resting blood pressure. The intervention also had an impact on the intestinal microbiota, where a lower relative abundance of bacteria of the genus Bacteroidetes and a higher relative abundance of microorganisms of the genus Alistipes , as well as an increased Shannon diversity index, were observed [ 126 ].…”

Root vegetables are known all over the world, but they are being less and less consumed by individuals. The main purpose of this article was to summarize the benefits, health effects, and threats associated with the consumption of carrot, celery, parsley, beetroot, radish, turnip, and horseradish. They are characterized by high nutritional value due to their richness in dietary fiber, vitamins, and minerals. One of their most important features is their high content of bioactive compounds, such as polyphenols, phenols, flavonoids, and vitamin C. These compounds are responsible for antioxidant potential. Comparison of their antioxidant effects is difficult due to the lack of standardization among methods used for their assessment. Therefore, there is a need for a reference method that would allow for correct interpretation. Moreover, root vegetables are characterized by several health-promoting effects, including the regulation of metabolic parameters (glucose level, lipid profile, and blood pressure), antioxidant potential, prebiotic function, and anti-cancer properties. However, due to the type of cultivation, root vegetables are vulnerable to contaminants from the soil, such as toxic metals (lead and cadmium), pesticides, pharmaceutical residues, microplastics, and nitrates. Regardless, the low levels of toxic substances present in root vegetables do not pose health risks to the average consumer.

“…While the anthocyanins listed in Table 2 are not unique to blackcurrants, they are present at higher levels than in other berries and plants, with blackcurrants containing 476 mg/100 g of anthocyanins, compared with 386 mg/100 g, 140 mg/100 g and 122 mg/100 g in blueberries, cranberries and cherries, respectively [46]. Furthermore, certain New Zealand cultivars are particularly high in anthocyanins, with the total anthocyanin content in New Zealand blackcurrant juices ranging between 346 and 850 mg/100 mL [70,71], compared to 179-310 mg/100 mL for non-New Zealand cultivars [72].…”

“…To date, several studies have investigated the effects of beetroot juice supplementation on blood pressure (Table 4), with most studies finding a significant reduction in blood pressure following both acute [31,98,99] and longer-term (1-8 weeks) supplementation [46,[100][101][102][103]; however, other studies have shown no positive effects [104][105][106]. Several factors may have influenced the outcomes from these studies, including participants' age, gender, BMI and/or beetroot dosage.…”

“…Both Beta vulgaris (beetroot) and Ribes nigrum (blackcurrant) have been studied for their bioactive potential in improving postprandial blood glucose [28,[36][37][38][39][40][41][42][43] and other risk factors associated with MetS [44][45][46]. This review, therefore, focuses upon and explores the current evidence for bioactive compounds in beetroot and blackcurrant and their impact on MetS risk factors.…”

Potential of Beetroot and Blackcurrant Compounds to Improve Metabolic Syndrome Risk Factors

et al. 2021

View full text Add to dashboard Cite

Metabolic syndrome (MetS) is a group of metabolic abnormalities, which together lead to increased risk of coronary heart disease (CHD) and type 2 diabetes mellitus (T2DM), as well as reduced quality of life. Dietary nitrate, betalains and anthocyanins may improve risk factors for MetS and reduce the risk of development of CHD and T2DM. Beetroot is a rich source of dietary nitrate, and anthocyanins are present in high concentrations in blackcurrants. This narrative review considers the efficacy of beetroot and blackcurrant compounds as potential agents to improve MetS risk factors, which could lead to decreased risk of CHD and T2DM. Further research is needed to establish the mechanisms through which these outcomes may occur, and chronic supplementation studies in humans may corroborate promising findings from animal models and acute human trials.
