Attention Deficit: Biological Condition or Cultural Creation?

What is attention deficit disorder?

In this latest episode of HumanOS Radio (iTunes, Stitcher, YouTube) I speak with Professor Stephen Hinshaw of UC Berkeley. Much of his research has focused on the causes of and treatment for hyperactivity and similar behavioral problems in children and adolescents.

In our chat, we discuss the background of ADHD, how it was historically characterized and diagnosed, and some of the many theories of what causes the condition. Then we will explore some of the most common treatments, as well as some of the unique challenges associated with understanding and resolving mental illness in general.


Sweeteners Part I: Sensation & Metabolism

We evolved to love sweet food – which is an adaptive preference for a hunter-gatherer. But in the modern world, we are inundated with tasty sugary treats 24/7. For many of us, this ready access to palatable food has come to the detriment of our waistlines, and has driven demand for sugar substitutes. Ostensibly, this might allow us to continue to fulfill our urge for sweet stuff without paying the price in extra calories. But is this safe? Or is it even an effective strategy?

In this article series, we will examine some of the evidence surrounding these sugar substitutes, and try to determine if they are indeed safe and effective. We will begin by discussing how these sweeteners are sensed by the body, and how the body handles them once they are consumed.
