Why lentils are underrated
Lentils are cheap, filling and nutritionally useful, which is why they deserve more respect than being hidden at the back of the cupboard behind three bags of pasta.
How to improve nutrient absorption
Lentils contain non-haem iron. Pair them with vitamin C rich foods such as peppers, tomatoes, broccoli or citrus to support absorption. Serving lentils with rice, bread or potatoes also makes meals more satisfying.
Who should be cautious
Lentils are high in fibre, so increase portions gradually if your gut is not used to them. Canned lentils are convenient, but choose lower salt versions where possible or rinse them.
Practical serving ideas
- Use this food as part of a meal, not as a single miracle ingredient.
- Pair it with fruit or vegetables for extra fibre, vitamin C and colour.
- Combine it with a protein source if you want the meal to keep you fuller for longer.
- Keep portions sensible, especially with calorie dense foods such as nuts, seeds and avocado.
