Why it scores 83
Red lentils achieve a strong FoodScore of 83/100, reflecting their excellent nutritional density. A major contributor to this high score is their substantial fiber content, with 7.9g per 100g serving, which earns a significant bonus due to fiber's recognized role in digestive and cardiovascular health. The 9.02g of protein per 100g also adds a valuable bonus, supporting muscle maintenance and satiety. Furthermore, red lentils are rich in several key micronutrients, including iron (3.33mg, 19% DV), zinc (1.27mg, 12% DV), and especially folate (45% DV), which collectively contribute an additional 8 points to the score. As a NOVA 1 food, meaning it is unprocessed or minimally processed, it receives a substantial 10-point bonus, aligning with dietary guidelines that emphasize whole foods. The absence of added sugar, very low sodium (2mg), and minimal total fat (0.38g) prevent any penalties, solidifying its high nutritional standing. To score even higher, red lentils would need to provide a wider range of micronutrients in very high percentages or contain beneficial fats like omega-3s, which are not present.
Health benefits
What the nutrients in red lentils cooked actually do for you, grounded in established dietary science.
Supports Heart Health
Red lentils are beneficial for cardiovascular health due to their high fiber content and favorable fat profile. The 7.9g of fiber per 100g, particularly soluble fiber, can help lower LDL cholesterol levels by binding to cholesterol in the digestive tract and facilitating its excretion. Additionally, red lentils are naturally very low in total fat (0.38g) and saturated fat (0.05g), which aligns with dietary recommendations for reducing the risk of heart disease. Their minimal sodium content (2mg) also supports healthy blood pressure. Regular consumption of legumes like lentils is emphasized in dietary guidelines for maintaining a healthy heart.
Aids Blood Sugar Management
The significant fiber content in red lentils makes them an excellent food for blood sugar management. With 7.9g of fiber per 100g, lentils help slow down the absorption of carbohydrates, leading to a more gradual rise in blood glucose levels after meals. This can be particularly beneficial for individuals managing diabetes or seeking to prevent blood sugar spikes. As a minimally processed whole food (NOVA 1) with no added sugar, red lentils contribute to a stable glycemic response. Research supports that diets rich in fiber-dense legumes can improve insulin sensitivity and overall glycemic control.
Promotes Digestive Health
Red lentils are a powerhouse for digestive health primarily due to their high dietary fiber. The 7.9g of fiber per 100g serving provides both soluble and insoluble fiber, which are crucial for maintaining a healthy gut. Insoluble fiber adds bulk to stool, aiding in regular bowel movements and preventing constipation. Soluble fiber acts as a prebiotic, feeding beneficial gut bacteria and supporting a diverse gut microbiome. A healthy gut microbiome is linked to improved digestion and overall well-being. Including lentils regularly can significantly contribute to meeting daily fiber recommendations.
Contributes to Satiety and Weight Management
With 9.02g of protein and 7.9g of fiber per 100g, red lentils are highly effective for promoting satiety and can be a valuable component of a weight management strategy. Both protein and fiber are known to increase feelings of fullness, which can help reduce overall calorie intake by curbing hunger and preventing overeating. The relatively low calorie density of 116 calories per 100g, combined with their nutrient richness, allows for satisfying portions without excessive caloric load. Incorporating lentils into meals can help individuals feel fuller for longer, supporting adherence to dietary goals.
Supports Muscle and Energy
Red lentils are a good source of plant-based protein and essential minerals vital for muscle function and energy production. Providing 9.02g of protein per 100g, they contribute to muscle repair and growth, especially when combined with other protein sources to form a complete amino acid profile. Furthermore, red lentils are an excellent source of iron, with 3.33mg per 100g, meeting 19% of the Daily Value. Iron is crucial for oxygen transport in the blood and preventing fatigue, directly impacting energy levels and physical performance. They also supply magnesium (9% DV) and zinc (12% DV), which are involved in numerous metabolic processes and muscle contraction.
Red lentils score very well at 83/100, primarily due to their high fiber and protein content, along with a rich micronutrient profile.
How to eat it
Red lentils are a versatile and quick-cooking legume, commonly used in a variety of dishes in American cuisine. They are often found in soups, stews, curries, and as a base for vegetarian burgers or meatless loaves. Their mild, slightly sweet flavor and soft texture make them an excellent addition to many meals, providing a nutrient-dense boost. A typical serving size is around 100g, which can easily be incorporated into main dishes or side salads.
For quick meals, use pre-cooked or canned lentils (rinsed well) to save time, or cook dried lentils from scratch as they require no pre-soaking.
Combine red lentils with whole grains like brown rice or quinoa to create a complete protein meal, enhancing the amino acid profile.
Add cooked red lentils to salads, grain bowls, or even smoothies for an extra boost of fiber and protein without significantly altering flavor.
Season lentils with herbs, spices, and a splash of vinegar or lemon juice to enhance their natural flavor and improve mineral absorption.
Store dried red lentils in an airtight container in a cool, dark place for up to a year, and cooked lentils can be refrigerated for 3-4 days or frozen for several months.
Things to keep in mind
Red lentils are generally considered safe and well-tolerated for most individuals when consumed in normal serving sizes. However, due to their high fiber content (7.9g per 100g), some people unaccustomed to high-fiber diets may experience mild gastrointestinal discomfort, such as bloating or gas, especially if consumed in large quantities. Gradually increasing intake and ensuring adequate hydration can help mitigate these effects. While legume allergies are possible, they are less common for lentils compared to peanuts or soy. Individuals with specific digestive conditions, such as Irritable Bowel Syndrome (IBS), might find that lentils, as a source of FODMAPs, could trigger symptoms in some cases, though tolerance varies. There are no widely documented significant interactions with medications or specific populations that require special caution for red lentils at typical consumption levels.
Yes, red lentils are very healthy, scoring 83/100 on FoodScore. They are a nutrient-dense food, rich in fiber (7.9g), protein (9.02g), and essential micronutrients like iron (19% DV) and folate (45% DV). As a minimally processed (NOVA 1) whole food, they align well with dietary guidelines for a balanced diet.
Are red lentils good for weight loss?

Are red lentils processed?
No, red lentils are considered an unprocessed or minimally processed food, categorized as NOVA 1. This means they are in their natural state or have undergone minimal processing, such as drying, without the addition of unhealthy fats, sugars, or artificial ingredients. They are a whole food choice.
How do I cook red lentils?
Red lentils are quick and easy to cook, typically requiring no pre-soaking. Simply rinse them thoroughly under cold water. For every cup of lentils, use about 2-3 cups of water or broth. Bring to a boil, then reduce heat and simmer for about 15-20 minutes, or until tender. They will break down and become creamy, making them ideal for soups and purees.
What can I use instead of red lentils?
If you don't have red lentils, you can substitute them with other types of lentils, though cooking times and textures may vary. Yellow lentils or split peas are good alternatives for dishes where a creamy texture is desired, like soups or purees. For dishes requiring more texture, green or brown lentils could work, but they will hold their shape better and take longer to cook.
Do red lentils provide complete protein?
Like most plant-based foods, red lentils are not a complete protein on their own, meaning they don't contain all nine essential amino acids in sufficient quantities. However, they are rich in many essential amino acids. To get a complete protein, you can easily combine them with grains like rice or quinoa, which provide the missing amino acids, making them an excellent part of a plant-based diet.
