Dementia symptoms include memory loss, difficulty concentrating and sudden mood changes.
Currently, about 850,000 people in the UK have dementia, and that number is expected to top one million by 2025.
But, eating broccoli could lower your risk of developing the condition, scientists have revealed.
Broccoli and other cruciferous vegetables help to lower the amount of homocysteine in the body – an amino acid that may cause Alzheimer’s disease in large quantities.
“Broccoli, cauliflower, bok choy, cabbage and brussels sprouts help retain memory,” said Dementia.org.
“They contain carotenoids and folate, which lowers levels of homocysteine, an amino acid linked with cognitive impairment.”
Carotenoids and folate are natural anti-inflammatories that work together to lower homocysteine levels in the body.
Scientists have claimed a folate deficiency, combined with high levels of homocysteine, increases the risk of Alzheimer’s disease.
Carotenoids have other health benefits too, including boosting eye health, immunity and may lower the risk of skin cancer.
Nutritionist Dr Josh Axe said: “We acquire carotenoids from eating certain plant foods, especially fruits and vegetables like carrots, sweet potatoes, tomatoes and squash.
“They’re phytonutrients that help fight free radical damage and provide important antioxidants to ward off disease and lower inflammation.”
You could also lower your risk of dementia by maintaining a healthy weight, exercising regularly, and by keeping blood pressure at a healthy level, the NHS said.
Dementia is a collection of brain conditions, that could cause memory loss, and difficulty with language, movement and judgment.
As the condition progresses, patients may experience bladder or bowel incontinence, trouble eating, and hallucinations.
If you’ve been experiencing symptoms for at least six months, you should see a GP.
Early diagnosis can help to slow down the disease’s progression, the NHS said.
