Salty food doesn't cause thirst:
Study
Contradicting the popular assumption of salt
causing thirst, it has been found that eating salty food does not necessarily
make us drink more water, says a study.
"Based on the notion that the consumption of salt increases thirst, the concern has arisen that it also leads to an increased consumption of sugary drinks. However, our study found little support for the assumption that salt invariably increases drinking," said Micah Leshem from the University of Haifa.
Leshem added that as we all consume beverages with high caloric content -- alcoholic or drinks -- there is evidence that increased consumption of salty foods leads to an overall increase in the consumption of calories that contribute to obesity.
In the study involving 58 participants, Leshem investigated the effect of salt in solid foods on drinking. Participants were asked to taste different types of nuts -- sugary candied nuts, salted nuts and nuts with no additives.
The researchers found that the level of reported thirst and the actual quantity of water that the subjects drank after eating salty nuts were not different than following consumption of candied nuts or nuts without added flavours.

Birth order has no effect on IQ
level: Study
The differences between first-borns and
"later-borns" are so small that they have no practical relevance to
personality or intelligence development of people, says a study.
The study observed 377,000 high school students and found that first-borns do have higher IQs and consistently different personality traits than those born later in the family chronology.
"This is a conspicuously large sample size," said lead author Brent Roberts in the department of psychology from the University of Illinois.
"It's the biggest in history looking at birth order and personality," Roberts said in the Journal of Research in Personality.
"The first-borns enjoy a one-IQ-point advantage over later-borns," said Rodica Damian, a professor of psychology at the University of Houston.
Though the difference is statistically significant, it is practically meaningless.
The analysis also revealed consistent differences in personality traits between first-borns and later-borns.
The first-borns tended to be more extroverted, agreeable and conscientious, and had less anxiety than later-borns.
"But these differences were small, amounting to a correlation of 0.02," Roberts said.
Previous studies of birth order suffered from small sample sizes as many compared children with their siblings -- a "within-family" design that some assert is better than comparing children from different families.
"The message of this study is that birth order probably should not influence your parenting, because it's not meaningfully related to your kid's personality or IQ," Damian said.
