Adding just two-and-a-half teaspoons of sugar to your tea DAILY increases your risk of Alzheimer's by 54%, study finds

Adding less than three teaspoons of sugar to your tea every day increases your risk of Alzheimer's disease, new research suggests.

Sweetening food or drinks with just two-and-a-half teaspoons of sugar makes people 54 per cent more likely to develop the condition, according to Daily Mail.

Indulging in just one can of sugary soda a day increases the risk of dementia by 47 per cent compared to those who only consume such beverages around once every three months, the research adds.

Speaking of the findings, Dr Doug Brown, said: 'Too much sugar is linked to type 2 diabetes and previous research has identified type 2 diabetes as a risk factor for dementia.

New drug for recurring malaria

A new drug to treat malaria has been given the green light by authorities in the United States.

The medicine is specifically for the recurring form of malaria - caused by the parasite plasmodium vivax- which makes 8.5 million people ill each year, according to BBC.

This type of malaria is a particular challenge to get rid of as it can remain dormant in the liver for years before reawakening many times.

Women who eat more than the recommended 5 portions of fruit and vegetables a day can reduce their risk of breast cancer by 11% study reveals

Women who eat at least five portions of fruit and vegetables each day can reduce their risk of breast cancer, a study claims.

Scientists found women who stick to the official nutrition guidelines have an 11 per cent lower chance of getting the disease, according to Daily Mail.

Broccoli, Brussels sprouts, carrots and yellow peppers all produced the strongest effects, researchers claimed.

Harvard University researchers analysed data from 182,000 women over 37 years to make the conclusion.

Participants completed dietary questionnaires every four years, which scientists then compared to the risk of diagnosis.

Sugar improves memory in over-60s, helping them work smarter

Sugar improves memory in older adults -- and makes them more motivated to perform difficult tasks at full capacity -- according to new research by the University of Warwick.

Led by PhD student Konstantinos Mantantzis, Professor Elizabeth Maylor and Dr Friederike Schlaghecken, the study found that increasing blood sugar levels not only improves memory and performance, but makes older adults feel happier during a task ,according to Science Daily.

The researchers gave young (aged 18-27) and older (aged 65-82) participants a drink containing a small amount of glucose, and got them to perform various memory tasks. Other participants were given a placebo -- a drink containing artificial sweetener.

The researchers measured participants' levels of engagement with the task, their memory score, mood, and their own perception of effort.

Obesity alone does not increase risk of death

Researchers at York University's Faculty of Health have found that patients who have metabolic healthy obesity, but no other metabolic risk factors, do not have an increased rate of mortality, according to Science Daily.

The results of this study could impact how we think about obesity and health, says Jennifer Kuk, associate professor, who led the research team at York University.

"This is in contrast with most of the literature and we think this is because most studies have defined metabolic healthy obesity as having up to one metabolic risk factor," says Kuk.
