lentils
Also known as: Lens culinaris, Lentils, Masoor Dal, Green Lentils, Red Lentils
Overview
Lentils (*Lens culinaris*) are legumes recognized as a rich source of protein, fiber, and essential micronutrients. They are a staple in various cuisines globally and are valued for their potential health benefits, primarily due to their high nutritional content. Lentils are commonly incorporated into diets to enhance fiber and protein intake. Research on lentils is extensive, with numerous studies examining their impact on health outcomes. The available evidence is generally robust, with systematic reviews and meta-analyses providing valuable insights into their benefits. They are available in various forms, including whole, split, red, green, and brown varieties, each with slightly different nutritional profiles and cooking times. Lentils are derived from the lentil plant, cultivated in many regions worldwide.
Benefits
Lentils primarily enhance satiety and may aid in weight management. A systematic review indicated that dietary pulses, including lentils, increase satiety by 31% compared to control foods. Fiber supplementation from lentils can also reduce fasting blood glucose levels. Higher legume intake, including lentils, is associated with reduced risks of all-cause and cause-specific mortality. These benefits are generally applicable across various populations, including individuals with diabetes or those seeking weight management. The effect size for satiety is significant, and the reduction in fasting blood glucose is clinically relevant for managing diabetes. The acute effects of lentils on satiety and blood glucose can be observed within hours after consumption.
How it works
Lentils primarily function through their high fiber content, which slows gastric emptying and reduces glucose absorption, thus improving blood glucose control. The protein and fiber in lentils also contribute to increased satiety by stimulating the release of satiety hormones. Lentils interact with the gastrointestinal system by influencing gut motility and hormone secretion. They also affect the metabolic system by modulating glucose and lipid metabolism. The fiber in lentils may interact with gut microbiota, influencing metabolic health. Cooking methods and the presence of phytates can influence the bioavailability of nutrients from lentils.
Side effects
Lentils are generally safe for consumption, with minimal adverse effects when consumed in moderation. The most common side effect is gastrointestinal discomfort, such as bloating or gas, due to their high fiber content. Allergic reactions are rare but possible in sensitive individuals. There are no significant drug interactions reported with lentil consumption. Individuals with severe gastrointestinal issues or known allergies to legumes should exercise caution. Pregnant or breastfeeding women can safely consume lentils as part of a balanced diet. It is advisable to gradually increase lentil intake to minimize gastrointestinal discomfort.
Dosage
While there is no strict minimum effective dose, incorporating lentils into meals can provide nutritional benefits. A common recommendation is to consume 1/2 to 1 cup of cooked lentils per meal for optimal nutritional benefits. There is no established maximum safe dose for lentil consumption, as they are a food item. Lentils can be consumed at any meal to enhance satiety and nutritional intake. Cooked lentils are more easily digestible than raw lentils. Cooking and soaking can improve nutrient bioavailability. No specific cofactors are required for lentil consumption. Individuals should adjust their intake based on their tolerance and dietary needs.
