Diabetes type 2 is caused by the pancreas not producing enough of the hormone insulin, according to the NHS.
Without enough insulin, the body can’t convert sugar in the blood into energy.
The condition increases the risk of serious long-term health conditions, including vision loss and kidney failure.
But, you could lower blood sugar by eating more sweet potatoes, a nutritionist has claimed.
“Sweet potatoes are high in many important nutrients” said nutritionist Dr Josh Axe.
“They’re are an excellent dietary addition for those with diabetes as they have been shown to help reduce and regulate blood sugar levels.
“Additionally, sweet potatoes are high in fibre, with each medium sweet potato fulfilling up to 15 per cent of your fibre needs for the entire day.
“Fibre slows the absorption of sugar to help prevent spikes and crashes in blood sugar levels.”
One specific type of sweet potato may have better blood sugar regulating properties than others; caiapo, Axe said.
Just four grams of caiapo a day could significantly lower blood sugar levels, scientists have claimed.
The vegetable could also improve insulin sensitivity in diabetes patients, they revealed.
Boosting insulin sensitivity helps the body to convert sugar into energy more efficiently.
Eating a healthy, balanced diet could lower your risk of developing diabetes, the NHS said.
You could be more at risk of diabetes if you’re overweight or obese, or are a smoker.
Regular exercise and drinking alcohol in moderation could also lower your risk of diabetes.
See your GP if you’re worried about the symptoms of diabetes. Early diagnosis could help to slow down the condition’s progress.
