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.

Too much salt may damage blood vessels and lead to high blood pressure

Eating a high-salt diet for several years may damage blood vessels -- increasing your risk of developing high blood pressure, according to research.

People with this type of blood vessel damage who eat a high-salt diet are more likely to develop hypertension, or high blood pressure . This research hints at the presence of a "sodium amplification loop" in which eating too much salt for a long time damages blood vessels, leading to a greater chance of developing high blood pressure if the high-salt diet is continued.

Researchers didn't assess the cause-and-effect relationship between salt intake and high blood pressure. But the study's results "add to the considerable evidence that a diet heavy on salt is closely linked to high blood pressure," said John Forman, M.D., lead author of the study.

What foods can help fight the risk of chronic inflammation?

A new study has identified food stuffs that can help prevent chronic inflammation that contributes to many leading causes of death.

Inflammation occurs naturally in the body but when it goes wrong or goes on too long, it can trigger disease processes. Uncontrolled inflammation plays a role in many major diseases, including cancer, heart disease, diabetes and Alzheimer's disease.

Diets rich in fruits and vegetables, which contain polyphenols, protect against age-related inflammation and chronic diseases.

Canine clues to brain tumour discovered

Brain tumours in dogs are similar to human ones and could give clues to how the disease develops, scientists say.

A study of 25 breeds of dog, has identified three genes linked with a severe type of brain tumour known as glioma, according to BBC.

Future investigation may yield a better understanding of the causes and potential treatments of brain tumours in dogs and humans, researchers say.

Gliomas are very severe human brain tumours that are often incurable.

Boosting mental performance with fish oil?

A particular fish oil (omega-3) supplement has been shown to improve blood flow to the brain during mental activity and to impact on certain aspects of mental performance in young adult.

In the first of two studies, researchers found that overall, taking either of two different types of fish oil supplement for three months had no consistent impact on mental function in 18 -- 35-year-olds, however they did find evidence of reduced mental fatigue and faster reaction times. Contrary to popular belief, these results suggest that taking omega-3 or fish oil supplements may not have an immediate or measureable impact on mental performance in healthy young adults, possibly due to the fact that this population is already performing at its mental peak or that higher dose or longer than 12 weeks supplementation are required
