Lentils provide more vitamin A, vitamin C, B6, folate, thiamin, niacin, B5, phosphorus, potassium, iron, copper, calcium and zinc than quinoa. Lentils contain fewer calories, carbohydrates and total fat.

In addition, lentils have a lower glycemic index than quinoa. This means less blood sugar spikes after consuming the food and slower digestion. Read more about the glycemic index down further in this article.

Quinoa is healthy also. It contains a good number of nutrients but just in fewer percentages. Quinoa provides more riboflavin and magnesium. In addition, quinoa contains fewer sugar.

Quinoa vs Lentils: Which to Choose

Quinoa and lentils are considered healthy, and you really can’t go wrong choosing either one. Some people will alternate between the two to avoid boredom. This also takes advantage of a wider variety of nutrients offered by both.

Some people have different goals which may sway your decision about which one to choose. Let’s take a look at some people’s common goals.

Weight Loss

Weight loss may be the most common goal of all. If you want to shed some extra pounds, you may ask, which is better for weight loss, quinoa or lentils?

Lentils are better for weight loss than quinoa due to its fewer calories, carbohydrates and fat. Quinoa contains 120 calories per 100 grams cooked. Lentils contain 116 calories per 100 grams cooked.

Lentils also have a lower glycemic index which means less blood sugar increases. This has been associated in some studies helping weight loss.

Gluten Free

Quinoa and lentils are naturally gluten free. In addition, quinoa can be made into flour and used as a substitute for regular flour in gluten free recipes.

Bodybuilding

If your goal is to gain lean muscle mass there’s a good chance you’re lifting weights at home or in the gym. Which is better for bodybuilding, quinoa or lentils?

Lentils are better than quinoa for bodybuilding due to its higher percentage of protein, vitamins and minerals. Lentils provide 9.02 grams of protein per 100 grams cooked. Quinoa provides 4.40 grams of protein per 100 grams cooked. 

This means lentils provide 105% more protein than quinoa. The extra amount of protein, vitamins and minerals help to repair and build new muscle after exercise.

Supplements for bodybuilding are expensive, and the costs add up pretty fast. Considering the price of both, lentils costs less than quinoa.

The lower priced lentils in combination with more protein, makes it a good choice for bodybuilding.

It seems every time I visit the supermarket the price is higher than the last visit. The cost of food certainly matters to most, especially with the rising costs of everything.

Therefore, the price may sway your decision about which one to use in your meals more often. Let’s examine, which costs more, quinoa or lentils?

Quinoa costs 220% more per 1/4 cup than lentils. The average price for quinoa is $0.57 per 1/4 cup. The average cost for lentils is $0.18 per 1/4 cup.

There didn’t seem to be a difference in price between white or tri-color quinoa in every store I checked. The red and black quinoa cost more than the white.

I decided to conduct a search of various different stores to compare the price of lentils and quinoa.

I checked Shoprite supermarket for the prices of lentils and quinoa:

Quinoa vs Lentils: Glycemic Index

The glycemic index of food is important especially if blood sugar levels are a concern. Avoiding blood sugar spikes is an important part of consuming healthy food. This is true for diabetics or anyone worrying about their health 3.

The Glycemic Index (GI) is a scale measuring how fast a particular food raises the blood sugar in the blood 4. Blood sugar spikes can lead to health complications with the heart, nerves, kidneys and eyes 5

Foods on the GI scale are categorized as:

  • Low-GI foods: 55 or under
  • Medium-GI foods: 56-69
  • High-GI foods: 70 or over

How blood sugars levels are affected:

  • Foods with a glycemic index 70 or more cause a quicker spike in blood sugar levels.
  • Foods with a glycemic index 56 to 69 cause a moderate spike in blood sugar levels.
  • Foods with a glycemic index 55 or less cause a slow spike in blood sugar levels.

Having more knowledge of the glycemic index of food and how it raises blood sugar, many people ask, does quinoa or lentils have a higher glycemic index?

Quinoa has a higher glycemic index than lentils although both are considered low-GI foods.

  • Red quinoa cooked in boiling water for 15 minutes has a glycemic index of 54.
  • White quinoa cooked in boiling water for 15 minutes has a glycemic index of 50.
  • Green lentils boiled have a glycemic index of 37.
  • Lentils, NS, boiled have a glycemic index of 29.

After boiling red quinoa has a glycemic load of 24, white quinoa 23 and lentils 6.

Quinoa vs Lentils: Satiety Index

Satiety is a term used to explain the feeling of being full and the loss of appetite which occurs after eating food. The satiety index is a scale showing how full a person feels after eating a certain food. 

The satiety index was developed in 1995 from a study which tested 38 foods. The foods were ranked how they satisfied a person’s hunger. Foods scoring under 100 are considered less filling and foods scoring above 100 are considered more filling 6.

The table below shows the satiety scores of lentils, some grains, oats, rice and a few other filling foods.

Food Satiety Index Score
White bread 100%
Brown rice 132%
White rice 138%
Lentils 133%
Wholemeal Bread 157%
Brown pasta 188%
Oatmeal w/milk 209%

Unfortunately, quinoa was not one of the 38 foods tested. A study in 2005, by the University of Milan, tested the satiety of quinoa, oats and buckwheat compared to eating rice. All three had a higher satiating efficiency than rice 7.

Since rice has satiety scores of 132% and 138%, we may be able to assume quinoa has a higher satiety score than 138%.

Lentils were included and categorized into the high protein food group. The satiety index score for lentils was 133%. This would indicate the satiety for quinoa is slightly higher than the score for lentils.

High satiety food like lentils and quinoa are likely to have a high satiety score for the following reasons:

  1. High in protein.
  2. High in fiber.
  3. High in volume (foods containing a lot of water or air).
  4. Low in energy density (foods low in calories for their weight).

Quinoa vs Lentils: Health Benefits

The nutrients provided by both are similar although lentils have a higher percentage of most. Therefore, they both offer similar benefits, but lentils may be more effective in some categories.

Let’s examine each of these nutrients, the percentages offered by both and the health benefits of those nutrients.

Protein

  • Cooked lentils contain 9.02 grams of protein per 100 grams.
  • Cooked quinoa contains 4.40 grams of protein per 100 grams.

Both are a good source of protein. Protein may help benefit the following:

  • Reduce appetite
  • Build and repair muscle
  • Boost metabolism
  • Weight loss

Fiber

  • Cooked lentils contain 7.9 grams of fiber per 100 grams.
  • Cooked quinoa contains 2.8 grams of fiber per 100 grams.

Both foods are high in soluble fiber, which is helpful for many reasons 8. What makes fiber soluble is it dissolves in water. 

Soluble fiber is known for the following:

  • Decrease the risk of diabetes by managing the blood glucose levels.
  • Helps avoid constipation and have a more regular stool.
  • Help overall digestive health.
  • Aids greatly in weight management because it allows you to feel full faster and eat less. 

Iron

  • Cooked lentils contain 3.33 mg of iron per 100 grams.
  • Cooked quinoa contains 1.49 mg of iron per 100 grams.

Lentils and quinoa are an excellent choice if you need getting your daily value of iron. Iron is essential in the creation of red blood cells and is a necessary part of any healthy diet. 

Iron is also vital for growth and development, as some hormones need iron to be appropriately balanced.

B Vitamins

Of the six B vitamins listed below, lentils provide a higher percentage of five of them compared to cooked quinoa.

The B vitamins provided include the following:

  1. B1 (thiamin) – Lentils
  2. B2 (riboflavin) – Quinoa
  3. B3 (niacin) – Lentils
  4. B5 – Lentils
  5. B6 – Lentils
  6. B9 (folate) – Lentils

B vitamins help support the following:

  • Digestion.
  • Brain function.
  • Cardiovascular disease.
  • Nerve function.
  • Red blood cells.
  • Energy levels.

A lack of B vitamins has been associated with oxidative stress and neural inflammation. In a study released in 2018 32 healthy adults were given B vitamin supplementation for six months. The results indicated preliminary evidence B vitamin supplementation reduced oxidative stress and inflammation 9.

Calcium

  • Cooked lentils contain 19 mg of calcium per 100 grams.
  • Cooked quinoa contains 17 mg of calcium per 100 grams.

Calcium is important for the heart and blood pressure. Harvard Health reports calcium helps maintain blood pressure by helping in the controlling of the relaxing and tightening of blood vessels 10.

Calcium also helps the following:

  • Help the muscles to function properly.
  • Helps nerve function.
  • Build and maintain strong bones.

Potassium

  • Cooked lentils contain 369 mg of potassium per 100 grams.
  • Cooked quinoa contains 172 mg of potassium per 100 grams.

Potassium helps the body get rid of excess sodium reducing fluid build-up. These help keep systolic and diastolic blood pressure lower 11.

According to Harvard Health, a number of studies have shown a connection between low potassium levels and high blood pressure 12. The more potassium, the more sodium your body will lose.

Consuming too much sodium or not enough potassium throws off the delicate balance the kidneys need to remove the excess water 13.

Magnesium

  • Cooked quinoa contains 64 mg of magnesium per 100 grams.
  • Cooked lentils contain 36 mg of magnesium per 100 grams.

Magnesium helps keep blood pressure levels stable and balanced. Recent scientific research examined previous studies and concluded magnesium supplementation decreased systolic and diastolic blood pressure 14.

Magnesium helps control the following:

  • Muscle
  • Insomnia
  • Blood sugar
  • Blood pressure
  • Nerve function

One reason many people supplement with magnesium in the evening is because it helps calm the whole body including blood vessels.

In the heart and muscles, magnesium competes with calcium to help the muscles relax after contracting. When the body is low in magnesium, calcium can over stimulate the heart muscle’s cells causing a rapid or irregular heartbeat 15.

Phosphorus

  • Cooked lentils contain 180 mg of phosphorus per 100 grams.
  • Cooked quinoa contains 152 mg of phosphorus per 100 grams.

Phosphorus has been shown in scientific studies to help with the following:

  • Help the body store and manage energy.
  • Muscle contraction.
  • Muscle recovery.
  • Help the kidneys remove waste.
  • Promote healthy nerve conduction.
  • Promote teeth and bone strength.
