NHS doctor urges increase in legume consumption to boost longevity

Sunday, 16 November 2025 5:05AM UTC

Dr Amir Khan highlights the health benefits of eating more legumes, citing research showing they can reduce the risk of death from various causes and promote longevity, with a focus on beans, lentils, and pulses as affordable, sustainable superfoods.

Dr Amir Khan, a practising NHS doctor and familiar face on ITV programmes such as This Morning and Lorraine, recently shared dietary advice aimed at boosting longevity and overall health. During an appearance on the No Appointment Necessary podcast, he emphasised the importance of increasing consumption of legumes, a food group he identifies as particularly beneficial for extending life expectancy.

Dr Khan defined legumes broadly, encompassing beans, lentils, chickpeas, and pulses, highlighting their dense nutritional profile. "Beans actually are one of the healthiest food groups you can have," he explained, underscoring the rich content of plant protein, fibre, and micronutrients that support gut health and bodily functions. He cited research indicating that individuals who consume the highest amounts of legumes have a 10 to 15 per cent lower risk of death from all causes compared to those who eat the least.

The British Heart Foundation (BHF) corroborates these claims, stating that pulses are among the highest fibre-containing foods available. A single portion provides about one-third of the daily recommended fibre intake, which is pivotal in lowering risks of heart disease, stroke, type 2 diabetes, and bowel cancer. The combination of protein and fibre in pulses also slows digestion, promoting satiety and helping with weight management. Three heaped tablespoons of pulses count as one of the recommended five daily portions of fruit and vegetables, as outlined in official dietary guidelines.

Beyond fibre and protein, pulses deliver an array of vital nutrients such as potassium, zinc, B vitamins, including folate, antioxidants, iron, selenium, and magnesium. These nutrients contribute to cell repair, immune function, and chronic disease prevention. Research published in the British Journal of Nutrition highlights that regular pulse consumption is linked to reduced risks of obesity, diabetes, heart disease, and certain cancers, reinforcing their value in a balanced diet.

Experts also highlight the affordability and sustainability of pulses. Campaigns such as "Anything is Pulse-able" by the Eating Better alliance point to pulses as a nutritious, low-cost protein source with a considerably lower environmental footprint than animal-based proteins, offering benefits both for individual health and planetary wellbeing.

Nutritionists advise incorporating a variety of legumes, including black beans, soybeans, and edamame, into daily meals to harness their broad spectrum of health-boosting properties. With ongoing concerns about chronic diseases and dietary quality, Dr Khan’s advice to prioritise legumes aligns well with both medical guidance and public health recommendations, making them a potent, practical choice for those seeking to live longer and healthier lives.
