Top five-a-day foods a new study says your heart needs
Britain's fruit and vegetable advice fits in a single phrase: five a day. A new analysis summarised by the BBC argues the composition of those five portions determines most of the outcome.
The study compares the dietary diaries of hundreds of thousands of adults tracked for more than a decade with their cardiovascular outcomes. The researchers single out five food groups associated with the steepest drops in heart attack and stroke risk.
The list clusters around five foods: leafy greens, red berries, citrus, pulses and nuts. Each brings a distinct profile — fibre, polyphenols or plant-based protein.
The effect of leafy greens is attributed to their nitrate and vitamin K content. According to the study, adults who eat a handful of spinach, kale or rocket a day post measurably lower blood-pressure readings on average.
Red berries — blueberries, blackberries, strawberries — stand out for their anthocyanin load. Smaller earlier studies had already linked those compounds to reduced inflammation in artery walls.
Citrus — oranges, mandarins and grapefruit — make the list as the main source of hesperidin, a flavonoid that can indirectly lower blood pressure, alongside vitamin C.
Pulses — beans, lentils, chickpeas — produce a measurable drop in LDL cholesterol when they replace refined grain or processed meat. The study points to three or four portions a week as the threshold.
Nuts — especially walnuts, almonds and hazelnuts — hold their heart-friendly profile despite being high in fat. A handful a day, roughly 30 grams, gives the clearest protective signal in the data.
Experts stress the list is a prioritisation, not a prescription. The benefit of carbohydrate-rich plants like potatoes, corn and bananas still stands; the study only measures which foods stand out when the question is narrowed to the heart.
