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 index", which represents the fullness per calorie of each food, normalized to white bread (white bread arbitrarily set to SI = 100). So for example, popcorn has a satiety index of 154, meaning it's more filling than white bread per calorie.
One of the most interesting aspects of the paper is that the investigators measured a variety of food properties (energy density, fat, starch, sugar, fiber, water content, palatability), and then determined which of them explained the SI values most completely.

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 WHS readers don't drink SSBs very often if at all, but I'm sure some do. Whether you want to try drinking fewer SSBs, or just re-affirm an ongoing commitment to avoid them, I encourage you to visit www.sodafreesundays.com and make the pledge. You can do so even if you're not a resident of King county.

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 trends. Since sugar is the most refined food we eat in quantity, and it's a good marker of processed food consumption, naturally I wanted to get my hands on sugar intake statistics-- but solid numbers going back to the early 19th century are hard to come by! Of all the diet-related books I've read, I've never seen a graph of year-by-year sugar intake going back more than 100 years.
A gentleman by the name of Jeremy Landen and I eventually tracked down some outstanding statistics from old US Department of Commerce reports and the USDA: continuous yearly sweetener sales from 1822 to 2005, which have appeared in two of my talks but I have never seen graphed anywhere else*. These numbers represent added sweeteners such as cane sugar, high-fructose corn syrup and maple syrup, but not naturally occurring sugars in fruit and vegetables. Behold:

Fat chance you may say but I overcame Obesity
After my daughter's birth I was busy nursing and taking care of her that I neglected my appearance. I guess this is something all of us do for a while after delivery. As a new mom you're busy enjoying motherhood and juggling house work, office as well as the new born. There is no time for grooming yourself and that is the time your treacherous body cheats on you. I put on weight and before long I was weighing 160 pounds. I was always short of breath and running around the house made me tired and weary through out the day. My temper was bad and my husband had a hard time wondering what's wrong with me. I couldn't fit into my clothes and had to sheepishly move towards the plus size counter at the store. I had severe back pain due to overweight and it was a task to get up from bed in the mornings. With physical obesity combined mental stress and I was on the verge of a breakdown.
I met my GP who advised me to start a diet program to lose weight. I tried but there was no sign of shedding the pounds. Meanwhile my low back pain continued and made life miserable for me. That is when my husband held my hand gently and talked to me about yoga. He showed me a few videos on You Tube and I was intrigued by this wonderful art form. Though skeptical I thought let me try, after all I've nothing to lose. The first few sessions went off well and I started to feel better mentally.
Yoga helps you to be agile
The basic yoga poses like padmaasan, suryanamaskar, trikonasana, paschimottanasana, pranayam gave me flexibility and I found myself being more agile. I started with the basic yoga poses and moved on to the intermediate level after two months. In these two months I could feel myself getting lighter and mentally I was more focused and relaxed than before.
Combine diet with yoga
Along with yoga I controlled my diet. I stopped eating sugar, starch and fats. Instead I devised a meal plan where I had a raw diet day, fish day and fruits evening in my menu. Instead of bacon and eggs for breakfast I substituted it with fruits and fresh cranberry/orange juice. Munching on carrots and nuts between meals kept the urge to chomp fries at bay.
Tuna fish for lunch along with salad, dressings with olive oil saw to it that I didn't add to the kilos. Following a strict yoga and diet regimen helped me to become flexible and shed the kilos. I came down to 120 pounds within two months. My back pain vanished like magic and I could fit into my old clothes. I felt so happy that I continued with the same diet and yoga sessions. Within four months I was looking my ravishing self and my husband just couldn't take his eyes off me. With inner glow thanks to yoga and a new haircut and shapely me, I am eagerly awaiting Valentine's Day. I am sure my husband will surprise me with gifts galore! Viola!!

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 of cigarette consumption over the last century in the US (1):

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. The talk was titled "The American Diet: a Historical Perspective"; you can access it by following that link.

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:
