Taste over health for blueberry consumers

According to a study by the University of Florida researchers, most of the blueberry buyers consume the fruit for its taste and not the health benefits.

They found that about 61 percent of the blueberry consumers prefers flavour over health, while 39 percent believe the fruit, which contains antioxidants, provides health benefits.

 Jim Olmstead, assistant professor, who will use the data to breed new types of blueberries, said that they were trying to determine what the consumers’ perception of the ideal blueberry was. Thomas Colquhoun, study’s co-author, said that historically, many blueberry traits had been selected with producers in mind, including climate adaptation, yield, harvest potential and disease resistance.

However, he added, developing a new blueberry variety could take more than 10 years.

Social media adversely affects mental health

A new study has suggested that social media like Twitter and Facebook can be harmful to one’s mental health. A 31-year-old woman was looked for the “Twitter psychosis” case after she was admitted to a psychiatric hospital in Berlin following a mental breakdown.

According to the doctors, the woman spent several hours a day reading and writing messages, neglecting her social relationships and even skipping meals and regular sleeping hours. The woman apparently believed that celebrities and organisations were using Twitter to try and reach out to her, and that there were symbols hidden within her feed and account.


The amount of symbolic language, the automated spam responses with seemingly related content, and the general interactive features of Twitter might combine several aspects that could induce psychosis, they said.

Stay stress-free for clear, acne-free skin

A new study has revealed that stress may be linked to inflammatory skin conditions, such as acne, psoriasis and rosacea and that it can make inflammatory skin conditions worse.

Richard D. Granstein said that nearly everyone has some form of stress in their life, so it’s difficult to determine whether stress can actually make the skin’s appearance worse and it’s been known now that the nervous system, processes our stress and has an impact on conditions such as psoriasis.

He said that if the nerves’ path to an area of a patient’s skin affected by psoriasis is interrupted, it’s been observed that the psoriasis improves and the condition also improves if local anesthetic is injected into psoriasis patches
.
Many types of cells in the skin, including immune cells and endothelial cells, can be regulated by neuropeptides and neurotransmitters, which are chemicals released by the skin’s nerve endings. Stress can result in the skin’s nerve endings releasing an increased level of these chemicals. When this occurs, it can affect how and at what level our body responds to functions such as sensation and control of blood flow.
 
No consensus over standard brushing methods

The researchers from University College London have revealed that there is no common recommendation on brushing method given by dental associations, toothpaste and toothbrush companies and in dental textbooks, across ten countries. They found a “worrying” lack of consensus between advices from dental associations compared with dental textbooks.

Aubrey Sheiham, senior author of the study, said that the public needed to have sound information on the best method to brush their teeth as different opinions from dental association, toothbrush companies and dentist might confuse them about how to brush.

The conflicting messages given by different organisations highlighted the need for research into how effective different brushing methods were, but at present, the experts recommend a simple scrubbing technique as it is easy to learn and there is no evidence to justify a more complicated method.
