However consuming crisps had no impact, the research, printed within the British Medical Journal (BMJ), discovered.

The researchers additionally famous that changing one serving a day of potatoes with one serving of non-starchy greens led to a 7 per cent drop within the danger of hypertension.

The staff, from the Brigham and Ladies’s Hospital and Harvard Medical College in Boston, Massachusetts, urged the excessive glycaemic index (GI) of potatoes could possibly be responsible.

Excessive-GI meals launch power extra rapidly and due to this fact increase blood sugar extra rapidly.

Within the UK, potatoes are extra extensively consumed than within the USA and make an necessary contribution to the consumption of vitamin C and potassium. The vitamin C and potassium content material is greatest retained when the potatoes are baked or boiled with skins on.”

Dr Louis Levy, head of vitamin science at Public Well being England, stated: “The Eatwell Information reveals that we must always base our weight-reduction plan on starchy meals akin to potatoes, that are greatest eaten with the skins on to extend fibre consumption.
