Palatability, Satiety and Calorie Intake

WHS reader Paul Hagerty recently sent me a very interesting paper titled "A Satiety Index of Common Foods", by Dr. SHA Holt and colleagues (1).  This paper quantified how full we feel after eating specific foods.  I've been aware of it for a while, but hadn't read it until recently.  They fed volunteers a variety of commonly eaten foods, each in a 240 calorie portion, and measured how full each food made them feel, and how much they ate at a subsequent meal.  Using the results, they calculated a "satiety...

Soda-Free Sunday

Last Thursday, I received a message from a gentleman named Dorsol Plants about a public health campaign here in King County called Soda Free Sunday.  They're asking people to visit www.sodafreesundays.com and make a pledge to go soda-free for one day per week.  Drinking sugar-sweetened beverages (SSBs), including soda, is one of the worst things you can do for your health.  SSB consumption is probably one of the major contributors to the modern epidemics of obesity and metabolic dysfunction.I imagine that most...

By 2606, the US Diet will be 100 Percent Sugar

The US diet has changed dramatically in the last 200 years.  Many of these changes stem from a single factor: the industrialization and commercialization of the American food system.  We've outsourced most of our food preparation, placing it into the hands of professionals whose interests aren't always well aligned with ours.It's hard to appreciate just how much things have changed, because none of us were alive 200 years ago.  To help illustrate some of these changes, I've been collecting statistics on US diet...

Cigarette Smoking-- Another Factor in the Obesity Epidemic

Obesity rates in the US have more than doubled in the last 30 years, and rates of childhood obesity and extreme adult obesity have tripled.  One third of US adults are considered obese, and another third overweight.  This is the "obesity epidemic". The obesity epidemic has coincided with significant changes in the US diet, which are clearly involved.  However, there's another probable contributor that's often overlooked: declining smoking rates.   Here's a graph I prepared of cigarette consumption over the...

My TEDx Talk, "The American Diet: a Historical Perspective"

On October 21st, I spoke at the Harvard Food Law Society's TEDx conference, Forum on Food Policy.  The conference kicked off with three talks on nutrition, by Drs. Walter Willett, David Ludwig and myself.  My talk is only 17 minutes long as per TED format, but it's packed with research on both quantitative and qualitative changes in the US diet over the last two centuries.  It contains surprises for almost anyone, and I can guarantee you've never learned this much about the history of the US diet in 17 minutes. ...

An Interview with Dr. C. Vicky Beer, Paleo-friendly MD

As I was preparing my recent article on the Paleo diet (1), I interviewed a local Paleo-friendly MD named C. Vicky Beer.  I was only able to include a snippet of the interview in the article, but I thought WHS readers would be interested to read the rest of the interview with Dr. Beer:Read more...
