What has more protein, lentils or peas? A definitive nutritional guide

4 min read

A 100g serving of cooked lentils provides roughly 9 grams of protein, a significantly higher amount than the 5.4 grams found in the same portion of cooked peas, settling the debate on what has more protein, lentils or peas. Both are valuable plant-based protein sources, but their nutritional profiles offer distinct advantages.

Quick Summary

Lentils consistently offer more protein and fiber per cooked serving compared to peas, which contain higher levels of certain vitamins. Choosing between them depends on specific dietary needs, but lentils are the clear winner for protein density.

Key Points

  • Protein Content: Cooked lentils contain significantly more protein per 100g (~9g) compared to cooked green peas (~5.4g).

  • Fiber Content: Lentils are richer in dietary fiber, which is essential for digestive health and satiety.

  • Vitamin Profile: Peas are the winner for certain vitamins, offering higher levels of Vitamin A, C, and K.

  • Mineral Content: Lentils typically have more iron, potassium, and phosphorus, while peas contain more calcium.

  • Culinary Versatility: Lentils have an earthy flavor and can hold their shape or become creamy, while peas offer a milder, sweeter flavor and a creamier texture when cooked.

  • Dietary Strategy: Combining legumes with grains throughout the day ensures a complete amino acid profile, making both lentils and peas excellent plant-based protein sources.

Legumes are a cornerstone of many healthy diets, particularly for those following vegetarian or vegan lifestyles. They are lauded for their affordability, versatility, and impressive nutritional content, including protein and fiber. Among the most popular options are lentils and peas, but many people ask: what has more protein, lentils or peas?

Protein Content: The Core Comparison

When comparing the protein content of lentils and peas, the preparation method is a key factor, as drying and cooking affect the final nutrient concentration. However, when examining cooked servings, lentils consistently outperform peas in terms of protein density.

Cooked Lentils

A 100g serving of cooked lentils, on average, provides about 9 grams of protein. The specific protein content can vary by type, but all lentils are excellent sources. Varieties like brown, green, and red lentils all offer a robust protein boost, making them ideal for soups, stews, and curries.

Cooked Peas

In contrast, a 100g serving of cooked green peas typically contains around 5.4 grams of protein. While still a decent amount for a vegetable, it is significantly less than lentils. Split peas, which are dried field peas, contain more protein by dry weight (~16g per serving), but this value decreases once cooked, bringing them closer to lentils per portion size.

Beyond Protein: Fiber and Micronutrients

While protein is a major consideration, a comprehensive comparison requires a look at other vital nutrients. The overall winner depends on whether you prioritize protein, fiber, or a specific vitamin profile.

  • Fiber: Lentils are richer in dietary fiber than peas. For every 100g cooked, lentils offer approximately 7.9g of fiber, while peas contain around 5.5g. A high-fiber diet is crucial for digestive health, blood sugar control, and weight management.
  • Vitamins: The micronutrient profile is where peas shine. Peas are notably richer in vitamins, particularly Vitamin A, Vitamin C, and Vitamin K. Lentils, however, are a standout source of folate (Vitamin B9), an essential nutrient, especially for pregnant women.
  • Minerals: Lentils generally contain more minerals, including iron, copper, potassium, and phosphorus. Peas, while still containing these, have a higher calcium content per serving.

Nutritional Comparison Table

To provide a clear overview, here is a comparison of the key nutritional aspects per 100g of cooked lentils and green peas:

Nutrient Cooked Lentils (per 100g) Cooked Green Peas (per 100g)
Protein ~9.02g ~5.36g
Fiber ~7.9g ~5.5g
Calories ~116 kcal ~84 kcal
Fats ~0.38g ~0.22g
Vitamin A Trace Significant Amount
Vitamin C Minimal Rich Source
Vitamin K Minimal Significant Amount
Folate (B9) Rich Source Moderate Amount
Iron Significant Amount Moderate Amount
Calcium Minimal Moderate Amount

Health Benefits and Culinary Uses

Both legumes offer numerous health benefits, making them valuable additions to any diet. Their specific properties influence their best use in the kitchen.

Health Benefits

  • Heart Health: Both are beneficial for cardiovascular health. Lentils, being particularly high in fiber and potassium, have been shown to help lower blood pressure.
  • Digestive Health: The high fiber content in both legumes aids digestion and supports a healthy gut microbiome.
  • Weight Management: The combination of protein and fiber promotes satiety, helping to manage appetite and aid in weight control.
  • Energy: Lentils are a great source of iron, which helps combat fatigue and is vital for energy production, especially for those on vegetarian or vegan diets.

Culinary Uses

  • Lentils: Known for their earthy flavor, different lentil varieties hold their texture differently. Brown and green lentils hold their shape well, perfect for salads and side dishes. Red lentils cook down quickly and become creamy, making them ideal for soups and curries.
  • Peas: With a sweeter, milder flavor, green peas are excellent in soups, pot pies, and stir-fries. Split peas, when dried and cooked, become creamy and are traditionally used for dense soups or as a meat alternative in dishes like veggie burgers.

Creating a Complete Protein Profile

One common concern about plant-based protein is its completeness. Plant proteins, including lentils and peas, are typically considered 'incomplete' because they lack or are low in certain essential amino acids compared to animal protein. However, this is not a major issue as long as you consume a variety of protein sources throughout the day.

  • Lentils are generally lower in the amino acid methionine but higher in lysine. Grains like rice are the opposite, high in methionine and lower in lysine. By combining lentils and rice throughout the day, you can get all the necessary essential amino acids.
  • Modern nutritional science emphasizes the importance of a varied diet over perfectly combining foods at every single meal. Eating a wide range of nutrient-dense plant foods is enough to meet your essential amino acid needs.

Conclusion: The Winner Depends on Your Goal

So, what has more protein, lentils or peas? For pure protein quantity per serving, lentils are the winner. They are also superior in fiber and several key minerals like iron and folate. However, peas hold their own, offering a richer profile of vitamins, including A, C, and K.

Ultimately, neither is 'better' in an absolute sense. The best choice depends on what nutritional benefits you are prioritizing. For a major protein boost in a plant-based meal, lentils are the champion. For a dish needing more vitamins like C or K, peas are an excellent choice. Both are highly beneficial legumes that deserve a regular spot in a healthy diet.

To maximize your nutrition, incorporate both into your meals. Use lentils in hearty stews and creamy curries, and add peas to stir-fries, salads, and soups for a pop of color and different nutrients. By consuming a variety of plant-based foods, you can easily meet all your nutritional needs without compromising on flavor or health. Health Benefits of Lentils and Types
