Protein Content and Quality

Lentils provide significantly more protein per serving compared to both white and brown rice, making them a superior plant-based protein source. Their protein contains essential amino acids, though lentils lack sufficient methionine, which can be complemented by grains such as rice.

  • Lentils contain about 9 grams of protein per 100 grams cooked, versus approximately 2.6–2.7 grams in rice.
  • The combination of lentils and rice creates a complementary amino acid profile, enhancing overall protein quality.
  • For vegetarians and vegans, lentils serve as a critical protein source, aiding muscle repair and immune function.

Dietary Fiber and Digestive Benefits

Dietary fiber plays a vital role in digestive health, blood sugar regulation, and cardiovascular health. Lentils are markedly higher in fiber than rice.

  • Lentils provide approximately 8 grams of fiber per 100 grams cooked, which is about 20 times more than white rice.
  • The fiber in lentils includes both soluble and insoluble types, promoting healthy bowel movements and feeding beneficial gut bacteria.
  • Brown rice has more fiber than white rice but still significantly less than lentils.
  • Higher fiber intake from lentils contributes to slower glucose absorption, reducing blood sugar spikes.

Impact on Blood Sugar and Satiety

The glycemic index (GI) measures how quickly a carbohydrate-containing food raises blood sugar levels. Foods with a low GI are generally better for metabolic health.

  • Lentils have a low GI (21-29), indicating a slow, steady release of glucose into the bloodstream.
  • White rice typically has a high GI (around 72), which can cause rapid blood sugar spikes.
  • Brown rice has a medium GI (50-55), providing a more moderate blood sugar response.
  • The low GI and high fiber content of lentils promote prolonged satiety and may aid in weight management.
