Ca regulă generală, lentilele convergente sunt mai groase la mijloc și mai subțiri pe margine, iar cele divergente mai subțiri la mijloc și mai groase pe margine. Dacă însă lentila se pune într-un mediu transparent cu indicele de refracție mai mare decât materialul lentilei, efectul este cel opus, iar lentila devine divergentă. formulă, se înlocuiește numeric f cu valori pozitive la lentilele convergente și cu valori negative la lentilele divergente. Lentils are high in fiber, which supports regular bowel movements and the growth of healthy gut bacteria. Eating lentils can increase your stool weight and improve your overall gut function ( 5). One 8-week study in 39 people with overweight or obesity and type 2 diabetes found that eating 1/3 cup (60 grams) of lentils each day increased levels of HDL (good) cholesterol and significantly reduced levels of LDL (bad) cholesterol and triglycerides ( 13).

The antinutrient content in lentils is significantly reduced by cooking. You can also soak your lentils overnight to lower the levels even further ( 23).

Five ways to cook lentils

Having overweight or obesity increases the risk of heart disease. Eating lentils may help decrease your overall food intake, which could contribute to weight loss or maintenance. Lentils are very filling and appear to keep blood sugar levels steady ( 9, 17, 18). Summary Pentru a obține grafic imaginea acestui punct, este suficient să fie reprezentate două din următoarele raze: Lentils improve the physical properties of soils and increase the yield of succeeding cereal crops. Biological nitrogen fixation or other rotational effects could be the reason for higher yields after lentils . [14] Climate requirements [ edit ] When tested in the lab, the polyphenols in lentils were able to stop cancer cell growth, especially on cancerous skin cells ( 6). The focus lies on high yielding and stable cultivars for diverse environments to match the demand of a growing population. [25] In particular, progress in quantity and quality as well as in the resistance to disease and abiotic stresses are the major breeding aims. [2] Several varieties have been developed applying conventional breeding methodologies. Serious genetic improvement for yield has been made, however, the full potential of production and productivity could not yet be tapped due to several biotic and abiotic stresses. [25]

In 2021, global production of lentils was 5.6 million tonnes, led by Canada with 29% and India with 27% of the world total (table). [9] Saskatchewan is the most productive growing region in Canada, producing 95% of the national total. [10] In India, Madhya Pradesh and Uttar Pradesh together produce more than 70% of the total. [11] Cultivation [ edit ] History [ edit ] It’s also worth noting that the polyphenols in lentils don’t appear to lose their health-promoting properties after cooking ( 6). The conditions under which lentils are grown differ across different growing regions. In the temperate climates lentils are planted in the winter and spring under low temperatures and vegetative growth occurs in later spring and the summer. Rainfall during this time is not limited. In the subtropics, lentils are planted under relatively high temperatures at the end of the rainy season, and vegetative growth occurs on the residual soil moisture in the summer season. Rainfall during this time is limited. In West Asia and North Africa, some lentils are planted as a winter crop before snowfall. Plant growth occurs during the time of snow melting. Under such cultivation, seed yields are often much higher. [14] Seedbed requirements and sowing [ edit ]Zhang, Bing; Deng, Zeyuan; Tang, Yao; etal. (2014). "Fatty acid, carotenoid and tocopherol compositions of 20 Canadian lentil cultivars and synergistic contribution to antioxidant activities".

Lentils also have antinutrient factors, such as trypsin inhibitors and a relatively high phytate content. Trypsin is an enzyme involved in digestion, and phytates reduce the bioavailability of dietary minerals. [23] The phytates can be reduced by prolonged soaking and fermentation or sprouting. [24] Cooking nearly completely removes the trypsin inhibitor activity; sprouting is also effective. [23] Breeding [ edit ] Egli, I.; Davidsson, L.; Juillerat, M.a.; Barclay, D.; Hurrell, R.f.

If you’re trying to minimize the number of lectins in your diet, try soaking lentils overnight and discarding the water before cooking them.
