Gum disease 'raises the risk of dementia by up to 70%

Having gum disease could increase the risk of developing dementia by up to 70 per cent, according to new research.

Results from a study of 28,000 people indicate that those who brush their teeth more are less likely to develop the disease according to Daily mail.

And experts said regular dental care may be promoted as a method of warding off Alzheimer's - if a link is confirmed by further research.

Gum disease, or peridontal disease, occurs when a build-up of plaque causes swelling and infections.

High dose injections of vitamin C

High dose injections of vitamin C could help to fight blood cancer and stop it from spreading, study claims
Super-strength vitamin C doses could be a way to fight, leukaemia 'exciting' early trials suggest.

Found in high levels in oranges, peppers and kale, scientists believe it encourages blood cancer stem cells to die according to Daily mail.

Faulty stem cells in bone marrow often multiply, fueling the growth of fatal tumours, but vitamin C tells them to die, scientists claim.

Peanut allergy treatment 'lasts up to four years'

An oral treatment for peanut allergy is still effective four years after it was administered, a study has found.

Children were given a probiotic, with a peanut protein, daily for 18 months.

When tested one month later, 80% could tolerate peanuts without any allergic symptoms and after four years, 70% of them were still able to eat peanuts without suffering any side-effects, according to BBC.

Food allergies have risen dramatically in recent decades, with peanut allergy one of the most deadly.

Children Who Sleep an Hour Less at Higher Risk of Type 2 Diabetes, Says Study

A study has found that children who slept on average one hour less a night had higher risk factors for type 2 diabetes, including higher levels of blood glucose and insulin resistance.

The NHS Choices recommended sleep duration for a 10 year old is 10 hours and so a child getting just one hour less has a higher risk, say researchers, according to Science Daily.

Professor Christopher G Owen, who led the research, said: "These findings suggest increasing sleep duration could offer a simple approach to reducing levels of body fat and type 2 diabetes risks from early life.

'Fat but fit' still risk heart disease

People who are overweight or obese are at increased risk of heart disease even if they appear medically healthy, experts are warning.

The work, in the European Heart Journal, is further evidence against the idea people can be "fat but fit".

The researchers studied health data on more than half a million people in 10 European countries, including the UK, according to BBC.

Normal blood pressure, cholesterol and blood sugar levels were no assurance of good heart health among obese people.
