Diabetes is a common condition that affects almost four million people in the UK.
Around 90 per cent of all diabetes cases are caused by type 2 diabetes.
The condition is caused by the pancreas not producing enough of the hormone insulin, or the body not reacting to insulin.
Eating certain foods could help patients to avoid blood sugar spikes. In particular, red onion may be crucial to controlling the condition.
Red onions could help to prevent high blood sugar spikes, revealed dietitian Juliette Kellow and nutritionist Dr Sarah Brewer.
Just one small onion – about 100g – could be enough to “significantly” lower blood sugar levels, they said.
The compound quercetin, which is found in red onions, is believed to be behind its beneficial effects.
“Red onions are a great source of heart-healthy and cancer-fighting quercetin,” they said in their book ‘Eat Better Live Longer – Understand What Your Body Needs To Stay Healthy’.
“Garlic and onions may help to lower blood sugar levels, making them beneficial for people with insulin resistance or diabetes.
“In one study of patients with diabetes, a 100g serving of red onion significantly reduced blood sugar levels.”
Diabetes patients should aim to eat plenty of vegetables to help control their condition, added medical website Water For Health.
Red onions appeared to be particularly helpful for managing blood sugar, it added.
But, don’t overcook vegetables, as they could lose their nutrient control, as well as their flavour.
Leafy green vegetables and low glycaemic-index foods are best options for diabetics.
But, starchy vegetables, including parsnips, sweet potatoes and pumpkin could be added to their diet plan, as long as their blood sugar levels are under control, it said.
Diabetes is a lifelong condition that can affect your everyday life, said the NHS.
It also increases the risk of some life-threatening complications, including heart disease and strokes.
Some people have type 2 diabetes without even realising it, because the symptoms don’t necessarily make you feel unwell.
Common diabetes symptoms include feeling thirsty all the time, unexplained weight loss, or having cuts or wounds that take longer to heal than normal.
Speak to a doctor if you’re worried about the signs of diabetes, or if you think you could be at risk of the condition.
