Lentils may have a potential effect in inhibiting free radicals expression in reduced risk and treatment of acute and chronic inflammatory diseases, some researchers opinionated.
Lentil is a type of pulse and tiny legume that can be cooked quickly and is rich in protein and fiber is a bushy annual plant of genus Lens to the Fabaceae family, native to the Middle East.
Antioxidants are types of chemical compounds that inhibited the expression of reactive oxygen and nitrogen species to protect the body against oxidative damage.
Reactive oxygen species (ROS) are key signaling molecules played an important role in the generation by polymorphonuclear neutrophils (PMNs) to induce the progression of inflammatory disorders and cytotoxicity in tumor cells. Overexpression of ROS and decreased antioxidant persistence also may cause endothelial dysfunction and tissue injury in the inflammatory sites.
According to the investigation of lentil (Morton) extract protective effect on cardiac hypertrophy, one of the most significant sequelae of cardiovascular diseases suggested that high phenolic compounds (43.4 mg of GAE/g), including thirteen phenolic acid and two flavonoids found in the acetone/water/acetic acid lentil extract, express a significant effect in attenuated Ang II-induced rat in an elevated contraction of blood vessels to cause hypertension and human cardiomyocytes hypertrophy, the loss of contractile mass from prior infarction through activated antioxidant activities in decreased intracellular ROS levels.
ROS elevation and decreased levels of antioxidants have been shown to increase oxidative stress in stimulated lipid peroxidation in the induction of endothelial cell damage and promoted lipid accumulated in the inner wall of arteries, through their effects on inflammation, disturbed blood flow, and arterial wall remodeling.
Lentil's antioxidant properties in the experiment of measurement of injection effects of 2,2-diphenyl-1-picrylhydrazyl (DPPH) in reduced antioxidant power in oxygen radical absorbing capacity, in vitro containing different groups of phenolic compounds also exerted the ability to inhibit the formation of reactive oxygen species, superoxide anion through chelating metal ions or inhibiting ROS -related enzyme expressions.
Furthermore, the analysis of free radical scavenging activities of methanolic extracts of the seed coat and the cotyledon of two varieties of lentils (Lens culinaris L.) and two varieties of dark peas (Pisum sativum L.), suggested that the deed coat of lentils scored a huge antioxidant capacities
compared to the cotyledon in lentils and peas through the significantly higher levels of phenolic compounds with flavonoid structure.
More interestingly, the evaluation of phenolic extracts from 20 Canadian lentil cultivars (Lens culinaris) for total phenolic contents and composition, antioxidant activities (DPPH, FRAP, ORAC), and inhibitory properties against α-glucosidase and pancreatic lipase suggested that phenolic compounds identified including the majority being flavonoids, kaempferol glycosides, catechin/epicatechin glucosides, and procyanidins not only demonstrate significantly antioxidant activities but also express a strong inhibition of α-glucosidase and lipase activities associated with glucose and lipid metabolism in the intestine.
Dr. Florinda Fratiannia, in the study of phenolic contents and antioxidant activities of grass pea (Lathyrus sativus), lentil (Lens culinaris), and chickpea (Cicer arietinum) cultivars from the Campania region of Southern Italy, postulated, "Lentils (cv Colliano and San Gerardo) demonstrated the highest antioxidant activity, (EC50 not higher than 2.3 mg/g), confirming that lentils are an excellent antioxidant food" and " these legumes can be considered therapeutic functional foods due to their significant content of functional proteins and carbohydrates and their extraordinary reserve of secondary metabolites and bioactive constituents that are beneficial for managing and preventing several chronic illnesses in humans".
People who are susceptible or at higher risk of infection may want to add some portions of lentils into
their diet to ameliorate ROS precipitation of inflammation.
The information findings suggested that lentils with huge numbers of phytochemicals may be considered as a functional food in stimulating antioxidant expression through the immune system in fighting against foreign invasion and preventing ROS overproduction in the induction of acute and chronic inflammatory diseases.
