Beans and Lentils — A Regular Legume Habit

Eat beans, lentils, chickpeas or peas regularly — an 80 g cooked portion counts toward the NHS 5 A Day — and add them gradually to limit bloating and gas.

The protocol

• Ramp: add them gradually and eat them regularly to reduce bloating and gas.
• Swap: use beans, lentils or chickpeas in place of some refined grains or meat in a meal.
• Portion: 80 g (about 3 heaped tablespoons) of cooked beans or pulses counts as one portion on the NHS 5 A Day guide; it counts once per day however much you eat.
• Duration: ongoing.

What you get

• Harvard Health describes legumes as rich in soluble fibre and resistant starch, which may help lower cholesterol, blood pressure and body weight.
• Harvard Health reports that beans have been linked to lower risk of heart disease and type 2 diabetes in observational research.

Contraindications

• Legumes can cause bloating and flatulence because gut bacteria digest sugars humans cannot break down; a sudden jump in fibre makes this worse, so increase slowly.
• People with chronic kidney disease or on dialysis should ask their renal dietitian first, because NIDDK lists beans among foods containing phosphorus that kidney patients may need to limit.
• People on a medically prescribed diet that restricts fibre should check with a clinician or dietitian before adding legumes.

Evidence level

Medium. The NHS counts pulses toward 5 A Day, and Harvard Health describes the heart and diabetes links as coming from observational research rather than randomised trials, so the benefits above are associations, not guarantees.
