Breastfed Babies Become More Intelligent Adults
Adults who were breastfed as babies tend to have higher intelligence, spend longer at school, and earn more income, regardless of their family's social class.
Adults who were breastfed as babies tend to have higher intelligence, spend longer at school, and earn more income, regardless of their family's social class. These results come from a new study out of Brazil that followed 6,000 individuals, beginning in their infancy, over the course of three decades.
About 3,500 of the study's participants, who are now 30-year-old adults, recently sat down to take a standard intelligence test. When researchers compared their scores with other data collected during the last 30 years, they found a positive correlation between having been breastfed and succeeding in life.
Leader of the study, Dr. Bernardo Lessa Horta, said from the Federal University of Pelotas, Brazil:
"Our study provides the first evidence that prolonged breastfeeding not only increases intelligence until at least the age of 30 years, but also has an impact both at an individual and societal level by improving educational attainment and earning ability."
While the study cannot account for all possible causes of school success — perhaps mothers who breastfed were also better tutors to their children — it does rule out family income as an explanation for success or failure. The reason, say researchers, is that at the time of the study, all Brazilian families breastfed their children, unlike in countries like Britain and the US where formula was thought healthier than mother's milk.
It's likely that breast milk helps the brain develop during the formative months of infancy, when the child begins taking in the world for the first time. In her Big Think interview, nutritionist and real foods advocate Nina Planck discusses the scientific turnaround concerning breast milk and how society has benefited form it:
"Breast milk is also very important to the growing child because it not only provides complete nutrition and provides a number of antibodies and really enhances immunity in multiple ways, but it develops and matures the digestive tract and the immune system. So it has effects ... it affects the whole developing child. Two of the three systems, which are immature at birth, immunity and digestion, are greatly enhanced by breast milk."

According to TwoFold CEO Alison McMahon, a leader who doesn't care (or can't pretend to care) about his or her employees isn't much of a leader at all.
Why do people quit their jobs? Surely, there are a ton of factors: money, hours, location, lack of interest, etc. For Alison McMahon, an HR specialist and the CEO of TwoFold, the biggest reason employees jump ship is that they're tired of working for lousy bosses.
By and large, she says, people are willing to put up with certain negatives as long as they enjoy who they're working for. When that's just not the case, there's no reason to stick around:
Nine times out of ten, when an employee says they're leaving for more money, it's simply not true. It's just too uncomfortable to tell the truth.
Whether that's true is certainly debatable, though it's not a stretch to say that an inconsiderate and/or incompetent boss isn't much of a leader. If you run an organization or company, your values and actions need to guide and inspire your team. When you fail to do that, you set the table for poor productivity and turnover.
McMahon offers a few suggestions for those who want to hone their leadership abilities, though it seems that these things are more innate qualities than acquired skills. For example, actually caring about your workers or not depending wholly on HR thinking they can do your job for you.
It's the nature of promotions that, inevitably, a good employee without leadership skills will get thrust into a supervisory position. McMahon says this is a chronic problem that many organizations need to avoid, or at least make the time to properly evaluate and assist with the transition.
But since they often don't, they end up with uninspired workers. And uninspired workers who don't have a reason to stay won't stick around for long.
