What are lentils?
Lentils belong to the legume (or pulse) family. They are the dried seeds of plants and come in various types, including red, yellow, green, French, and Puy.
Why Lentils are a Nutritional Powerhouse:
Carbohydrates: Your body’s preferred source of fuel, helping to keep your heart beating, blood pumping, brain thinking and digesting food.
Plant-Based Protein: Essential building blocks for tissue repair and hormone production.
Dietary Fibre: Contains both soluble and insoluble fibre for healthy bowel movements.
Resistant Starch: Your gut bacteria’s absolute favorite food.
Vitamins & Minerals: Rich in Folate, Iron, Zinc, and Magnesium to reduce fatigue and support bone health.
Antioxidants: Protect your cells from free radical damage.
6 Evidence-Based Health Benefits of Legumes
Adding lentils and pulses to your diet isn't just about gut health—it's about whole-body wellness. As a dietitian, I recommend daily consumption because the research is clear:
Heart Health & Blood Pressure: Daily legume consumption helps to reduce "bad" (LDL) cholesterol, increase "good" (HDL) cholesterol, and support healthy blood pressure levels.
Diabetes Management: Eating legumes daily reduces fasting blood glucose and insulin levels. Over the long term, this helps improve HbA1c and significantly reduces the risk of developing Type 2 Diabetes.
Cancer Protection: Evidence suggests that legumes may be protective against cancers of the bowel, breast, lung, and prostate.
Constipation Relief: Thanks to their high fibre content, regular legume consumption is a natural and effective way to relieve constipation.
Better Mineral Absorption: Did you know legumes help increase the amount of calcium your body absorbs from other foods?
The Secret to Longevity: For every 20g increase in your daily legume intake, there is a 7–8% reduction in the risk of death. They truly are a superfood for longevity!
The Science: Why Lentils Are Good for Gut Health
Lentils contain a specific type of carbohydrate called Galacto-oligosaccharides (GOS).
Humans lack the enzyme (alpha-galactosidase) to break GOS down in the small intestine. This is actually a good thing! Because we can’t digest it, GOS travels to the large intestine where it is fermented by your gut microbes.
The Benefits of Fermentation:
When your gut bacteria (like Bifidobacteria and Lactobacilli) feast on the lentils, they produce Short-Chain Fatty Acids (SCFAs) like butyrate. These SCFAs:
Fuel the cells lining your gut.
Reduce inflammation.
Support a strong immune system.
Dietitian Tip: If you aren't used to eating lentils, start with small portions. The gas produced during fermentation is a sign your bacteria are working, but your gut needs time to adjust to the increased "fuel!"
Chana Dahl Recipe
Serves 4 I Prep time: 10 mins I Cook time: 1 hour
Ingredients
1 cup chana dal (split chickpeas)
1 brown onion, diced

Build the Spice Base: Stir in the ginger, turmeric, coriander, garam masala, tinned tomatoes, and the stock cube.
Combine: Add your cooked lentils to the spice mix. Add a splash of boiling water to reach your desired consistency.
