Polyphenols, Beta-Sitosterol and Vitamin K reduce fat deposits in blood vessels, acting as cardioprotectors.
Combined with the Flavonoids found in Moringa, these elements are vital to ensuring heart health in the long term.
Catechins are the most important Flavonoids in the human diet. Beneficial for blood circulation, in varicose vein treatment and phlebitis, they also improve capillary flexibility and therefore, enhancing their resistance so that their breaking ratio is reduced and preventing hemorrhages, haematomas and nosebleeds.
Catechins raise the absorption of Vitamin C, which is in charge of preventing the blood vessels from oxidation. Its capacity for diminishing arterial pressure and lower cholesterol and triglycerides means an advantage in the balanced health of the cardiovascular system. The Catechins improve the blood plasma antioxidant capacity and increases the active life of Vitamin E and Beta-Carotene. The richest sources of Catechins are Green tea and Moringa.
The Beta-Sitosterol protects the heart. Calcium, Magnesium and Potassium improve cardiac efficiency. Selenium also reduces attacks and cerebrovascular accidents.
Quercetin inhibits lipid peroxidation at microsomal levels, in the heart, leading onto a cardioprotector effect and protecting it from CVAs (cardiovascular accidents). It has a vasodilator effect. Also, it can potentially interact with most of the molecular targets involved in the pathophysiology of Ischemic Cardiopathy and Brain Hemorrhage. Therefore, Quercetin can act through different mechanisms that operate in the long term prevention as well as in the acute phase of cardiovascular events.
Flavonoids produce a profitable synergy working with other antioxidant vitamins such as Vitamin C and E, increasing its absorption.
According to Carmen Menéndez Soriano in her doctoral thesis ‘Efectos vasculares de la Quercetina y la Catequina’ (1) (‘Vascular effects of Quercetin and Catechins’), epidemiological studies link a lower incidence of cancer and cardiovascular diseases to a higher intake of flavonoids:
In a recent study published by (Sultana et al., 2008), the level of flavonoids was determined in 22 plants (9 vegetables, 5 fruits and medicinal plants). The higher concentration was measured in moringa medicinal plant (Moringa Oleífera; 68 g g-1) followed by strawberry plant (Fragaria spp.; 40 g g-1), sacred fig tree (Ficus religious; 12 μg g-1), spinach (Spinaceae oleraceae; 19 μg g-1) and cauliflower (18 μg g-1).
Unlike the traditional vitamins, flavonoids are not essential for the short term well-being, but an increasing evidence suggests that its intake in the mid-long term would modulate the human metabolism in a favourable way, preventing or reducing the risk of degenerative illnesses, such as cardiovascular, diabetes, obesity and cancer.
