Adolescents’ brains process sugar differently

A new study has revealed that adolescent brains process sugar differently than adult brains.

According to the study by researchers at the Yale School of Medicine, inadolescents,  increased the blood flow in the regions of the brain implicated in reward-motivation and decision-making, whereas in adults, it decreased the blood flow in these regions.

Lead researcher Ania Jastreboff said that that while they cannot speculate directly about how glucose ingestion may influence behavior, their study has certainly shown that there are differences in how adults and adolescents respond to glucose

The researchers said that it is important because adolescents are the highest consumers of dietary added sugars and it is just the first step in understanding what is happening in the adolescent brain in response to consumption of sugary drinks.

The study was presented at the American Diabetes Association's 74th Scientific Sessions.

Stop washing chicken before cooking to avoid food poisoning

Experts have warned that people should stop washing chicken before cooking it so that they can avoid food poisoning.

The British Food Standards Agency has issued a call to the public to stop the practice, as more than two-fifths of cooks say that they wash chicken as part of their food preparations, News.com.au reported.

Campylobacter bacteria is responsible for the majority of cases of food poisoning and the FSA said four out of every five cases are caused by contaminated chicken, where in most cases people suffer from abdominal pain, severe diarrhoea and vomiting, some cases can lead to more significant health problems.

FSA chief executive Catherine Brown said that although people tend to follow recommended practice when handling poultry, such as washing hands after touching raw chicken and making sure it is thoroughly cooked, their research has found that washing raw chicken is also common practice.

n that brings together the whole food chain, which includes working with farmers and producers to reduce rates of campylobacter.

Genome sequence of parasites may help interventions

A new study has found vital biological and genetic information from sequence of genomes of the whipworm, an intestinal parasitic worm that infects many people in the developing countries.

The whipworm is one of three types of soil-transmitted parasitic worms that collectively infect nearly two billion people, while infections often result in mild disease they may also lead to serious and long-term damage such as
malnutrition, stunted growth and impaired learning ability.

Dr Matthew Berriman, senior author from the Wellcome Trust Sanger Institute said that their work starts to unravel the whipworm’s intimate relationship with humans and paves the way for new approaches to prevent or clear whipworm infections.

He further explained that making these genome sequences freely available will provide an enormous boost to the entire research community that is working on interventions to prevent or treat worm-associated disease.

This study not only opens doors for the development of new drugs but may also allow the researchers to identify already existing drugs used for other
diseases that might be effective against this parasite and other types of worms.

Professor Richard Grencis, senior author from The University of Manchester said that although whipworms can be detrimental to human health and economic growth in some regions, they are also important in defining human immune system’s ‘set point’ and ensuring we make the right level of immune response during disease.
