Most cultures include alcoholic beverages as part of their usual diet. Alcohol intake is different over world regions regarding the habitual type of beverage and the frequency and average intake. In general terms, the consumption of alcoholic beverages is increasing worldwide. Unipolar depression is the most prevalent mental disorder in the world and it is increasing steadily.... Read more »

Perhaps it is will to be the future’s way of detecting colorectal cancer in an early stage: sniffing poo with an electronic nose. The medical centre of the Vrije Universiteit in Amsterdam succesfully tested their new device and published the results yesterday in the International Journal of Cancer.... Read more »

It may have been more than 2000 years ago, but Hippocrates was not far from the truth when he wrote “all disease begins in the gut”. Gut health is critical to overall health. Colonies of benevolent bacteria reside in your entire digestive tract, predominantly the large intestine. In fact, you are made up of more microbes than human cells. This live-in colony of microbes is your digestion powerhouse, breaking down food into its building blocks so it can absorb the nutrients.... Read more »

Diet drinks are no help in the fight against obesity and may actually encourage over-eating, according to a US academic who recently argued this point in the journal Trends in Endocrinology and Metabolism.
Susan Swithers reviewed studies that suggest normal or mildly overweight people who consumed artificially-sweetened drinks were more likely to gain weight when compared to those who did not.
The studies showed that, in two separate groups of adolescents, drinking artificially-sweetened drinks was associated with increased body mass index and body fat.... Read more »

Edible insects are great alternatives to conventional sources of meat as they’re cheap, plentiful and excellent sources of protein and fat, as well as vitamins and minerals.
In many countries, eating insects doesn’t raise eyebrows. How palatable they appear to a person is largely determined by culture.
Analyses of insects also show huge variation in nutritional value and composition – between species, their stages of development and even due to the insects’ diet.
With around 2000 edible insect species worldwide, the below are some of the better alternatives to eat... Read more »

Forget natural resources and cheap labor, argues Rus Mircea-Iosif in his recently published paper Annals of the University of Oradea : Economic Science.

We all have that Facebook contact (if not, in the old sense of the word, friend) who is subject to oversharing. Incessant updates about relationships, jobs, holidays; very public demonstrations of affection; insistent “liking”: the site is full of serial offenders. But for most, this generally amounts to a minor annoyance or something to laugh about. A recent study, however, has argued that sharing photographs on Facebook can, and does, have a direct impact on our personal relationships offline too.... Read more »

From Siri answering our questions and Watson advising nurses to smart apps that aggregate information to help us out (or spy on us), artificial intelligence is transforming our world. Despite incredible advances, somehow these amazingly “intelligent” systems sometimes seem profoundly stupid. Hector Levesque, a professor of computer science at the University of Toronto, likens them to savants. He was recently awarded the Research Excellence Award at the International Joint Conference on Artificial Intelligence in Beijing; he used his acceptance speech to highlight important questions about our approach to artificial intelligence and what it can tell us about ourselves....

With easy access to energy-rich junk food and modern living with a sedentary lifestyle, more and more people are becoming slaves to excessive fat consumption. Yet being a couch potato is dangerous for our health. Studies on the human genome variation show there are significant differences in the genome of bacteria that live in our intestine. A latest research published in Nature reveals that the bacterial population in the intestine varies significantly from obese to thin bodies. This indicates that people with fewer bacterial species in their intestine are more likely to develop complications, such as cardiovascular diseases and diabetes.... Read more »

A recent study published by Italian researchers shows that adhering to a Mediterranean-style diet can offer protection against type 2 diabetes. The paper is just the latest in a long line of research pointing out the wonders of this diet – so what are we to take from these latest findings?... Read more »

New research from the University of Helsinki suggests that humans begin to distinguish between sounds before they are even born. Eino Partanen and colleagues explored how prenatal experiences influence learning. “We wanted to find out what kind of material foetuses can learn in the womb, what kind of neural representations they form,” he said....

Antioxidants are part of our daily diet in fruits, vegetables, spices, and herbs, and their intake is the focus of increasing attention. More recently, designer foods have been enriched with antioxidants, and antioxidants are commonly taken as supplements. Here is five misconceptions about the benefits of antioxidants.... Read more »
Body fat is composed of white/beige adipose tissue (WAT) and brown adipose tissue (BAT). While WAT is mainly used to store energy, BAT is important for heat production when the body is exposed to cold, and for this reason it’s abundant in infants who are more susceptible to cold than adults....
