Lentil (Lens culinaris) is an important nutritious crop, grown and consumed throughout the world due to its high macro- and micronutrients contents, including minerals. Minerals have several beneficial influences on human health. Thus, lentils play a major role in food security, particularly among low-income countries. The current review aims to highlight the present knowledge on the mineral composition of lentils, compare it with the recommended dietary allowance and adequate intake of minerals, investigate the literature regarding its physiological role, give detailed information on different antinutritional factors preventing its bioavailability, and present adopted solutions to enhance the bioavailability of minerals in lentil seeds. Thereby, a literature search was conducted using reliable sources: Elsevier, Springer, PubMed, and CrossRef. Based on the previous studies, 100 g of cooked lentils, for example, may be enough to cover the recommended dietary allowance/adequate intake of iron in infants under six months and children aged one to three years. One hundred grams of cooked lentils may also cover the recommended dietary allowance/adequate intake of zinc and magnesium in infants and children aged one to three years. Hence, it is imperative that the scientists continue to show the significance of pulses as a mineral source and their effects on human health. Indeed, lentils should be exploited for a variety of purposes, mainly towards eliminating malnutrition, on the condition of being well-balanced. Lentils should be incorporated either in snacks or while preparing household, school, or hospital meals, particularly in developing countries.

Introduction: The current study aimed to explore the in vitro antioxidant, anti-inflammatory, antidiabetic, and dermatoprotective properties of lemon peel essential oil (EO). Methods: The chemical composition of lemon EOs extracted from the lemon of three cities in Morocco was investigated using gas chromatography-mass spectrometry (GC-MS) analysis. The antioxidant property was estimated by two complementary tests: Ferric ion reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH). The in vitro anti-inflammatory activity was assessed by the inhibition of albumin denaturation and proteinase. Inhibitory properties of α-glucosidase and α-amylase were used to reveal the antidiabetic activity of lemon peel EOs. Dermatoprotective property was evaluated by the tyrosinase inhibition method. Results: In addition to high amounts of polyphenols and flavonoids, GC-MS analysis of lemon peel EOs demonstrated the presence of D-limonene, β–pinene, and γ-terpinene as the main compounds in the three samples studied. Lemon peel EOs exhibited significant antioxidant activities by IC50 values ranging from 40.57 µg/mL to 100.22 µg/mL and 113.63 µg/mL to 180.90 µg/mL obtained by DPPH and FRAP tests, respectively. in vitro inhibition of enzymes involved in inflammatory response revealed that lemon peel EOs presented remarkable inhibitory activities against albumin denaturation (230.48 µg/mL>IC50<341.13 µg/mL) and proteinase (199.70 µg/mL>IC50<307.05 µg/mL). Moreover, lemon peel EOs demonstrated powerful inhibition of α-amylase and α-glucosidase with various IC50 values (1689.06 µg/ mL>IC50>4000 µg/mL and 1021.58 µg/mL>C50<2467.62 µg/mL), respectively. These EOs also revealed significant inhibition of tyrosinase with IC50 values ranging from 248.42 μg/ mL to 378.02 μg/mL. Conclusion: These results revealed that lemon peel EOs might constitute a new product with beneficial biological abilities against the mentioned complications.
