How much sugar is in your child's fruit drink?

Researchers and colleagues from Action on Sugar have assessed the sugar content of over 200 fruit drinks marketed at children and have found them to be "unacceptably high."

To assess the sugar content of fruit juice drinks, 100% natural juices, and smoothies marketed specifically to children, the researchers measured the quantity of 'free' sugars in 203 standard portion sizes (200 ml).

'Free' sugars refer to sugars, such as glucose, fructose, sucrose, and table sugar, which are added by the manufacturer, and naturally occurring sugars in honey, syrups, fruit juices and fruit juice concentrates, but not the naturally occurring sugars found in whole fruits and vegetables, which the body metabolises differently and which act to curb energy intake.

Exercise may slow brain aging by 10 years for older people

Exercise in older people is associated with a slower rate of decline in thinking skills that occurs with aging. People who reported light to no exercise experienced a decline equal to 10 more years of aging as compared to people who reported moderate to intense exercise, according to a population-based observational study.

"The number of people over the age of 65 on the rise, " said study author Clinton B. Wright, MD, MS. "Our study showed that for older people, getting regular exercise may be protective, helping them keep their cognitive abilities longer."

Poor diet and lack of exercise accelerate the onset of age-related

Could an unhealthy diet and lack of exercise be making you age faster? Researchers believe there is a link between these modifiable lifestyle factors and the biological processes of aging. In a recent study, researchers demonstrated that a poor diet and lack of exercise accelerated the onset of cellular senescence and, in turn, age-related conditions in mice. Results appear today in Diabetes.

It's grapes that are great for your eyes - and could reduce the risk of blindness later in life

Generations of children have had to be cajoled into eating their carrots with the promise that the vegetables are good for their eyesight.

Now new research has delivered a much sweeter deal, revealing that eating grapes is good for the eyes and could reduce the risk of going blind later in life.

The fruit protects against a chemical process known as oxidative stress, which releases harmful molecules called free radicals into the retina, the study found.

'Cold turkey' best way to quit smoking, study shows

People who want to quit smoking are more likely to succeed if they go "cold turkey" by stopping abruptly, a study in Annals of Internal Medicine shows.

Volunteers who used this approach were 25% more likely to remain abstinent half a year from the date that they give up than smokers who tried to gradually wean themselves off instead.

The NHS says that picking a convenient date to quit is important, according to BBC.
