People who eat nuts have reduced risk of dying from cancer or cardiovascular disease

People who eat nuts, particularly walnuts, are more likely to live longer, finds research. In a study, researchers suggest that those who eat nuts more than three times a week have a reduced risk of dying from cancer or cardiovascular disease than non-nut eaters.

The research study the effect on the primary prevention of cardiovascular disease of over 7000 older people (aged 55 to 90) randomized Diet supplemented with extra virgin olive oil or nuts, compared to a control group following a low fat diet. People who ate nuts tended to have a lower BMI and smaller waist. They were also less likely to smoke and were more physically active than those who rarely or never ate nuts. Nut eating was associated with a better diet in general as these people ate more vegetables, fruit and fish.

For some U.K. teens, sun doesn’t provide enough vitamin D

At one point in the year, almost 80 percent of teens in a UK study had insufficient vitamin D that should come from sun exposure, and one quarter had insufficient levels even at the peak of summer, according to a new study.

The results were surprising because the participants were white children, whose skin is the most sensitive to ultraviolet-B and who therefore need the least amount of sunlight exposure to get enough vitamin D, said senior author Lesley E. Rhodes of the University of Manchester in the U.K, according to Reuters.

Most vitamin D is synthesized in the skin after exposure to UVB rays from the sun, Rhodes and colleagues write in the Journal of Clinical Endocrinology and Metabolism.

How to look 5 years younger in 5 easy steps

The adage goes that 'you are what you eat', according to a team of nutritionists, when it comes to looking younger it is the truth.

By making a few small changes to your diet, it is possible to turn back the clock, they say.

1. No sugar, please!

Sugar affects general health, raising the risk of obesity and its myriad of complications.

But, the sweet stuff can also wreak havoc with our skin

Nutritionist Cassandra Barns, explains: 'Firstly, sugar and refined carbohydrates, which are quickly absorbed, just like sugar, cause a surge of the hormone insulin.

'This can increase levels of testosterone, which in turn can contribute to breakouts and acne.'

Concern Zika causes baby eye problems

Scientists studying the Zika outbreak in Brazil are becoming increasingly concerned the virus may cause eye damage in babies.

Stanford University researchers found abnormal bleeding and lesions in the eyes of three infant boys whose mothers had caught Zika while pregnant, according to BBC.

They want any babies known to be affected by Zika to have eye checks.

The disease is already known to cause a serious baby brain defect called microcephaly.

What is not clear is whether eye problems might be a complication of this rather than the Zika infection itself. Either is possible.

Public Health England: Advice to eat more fat 'irresponsible'

Advice to eat more fat is irresponsible and potentially deadly, Public Health England's chief nutritionist has said.

Dr Alison Tedstone was responding to a report by the National Obesity Forum, which suggests eating fat could help cut obesity and type 2 diabetes, according to BBC.

The charity said promoting low-fat food had had "disastrous health consequences" and should be reversed.

Other experts have also criticised the recommendation to eat more fat, saying the report cherry-picked evidence.
