Sugar: The Bitter Truth by Robert H. Lustig, MD

I came across this information recently and thought it would be good to share.  “Food for thought” so to speak.  Enjoy! RMS

Robert H. Listig, MD a UCSF Professor of Pediatrics in the Division of Endocrinology, explores the damage caused by sugary foods. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin.

What does the Atkins diet and the Japanese diet have in common.
Atkins is all fat and no carbohydrates
Japanese is all Carbohydrates and no fat
Both diets work because they both eliminate fructose.
Today we are all 25 pounds heavier than we were 25 years ago.
Everyone talks about fat genes and genetics but we did not genetically change in the last 25 years, our environment did.
There is something wrong with our brain chemistry biofeedback loop.  Leptin, the hormone that tells us we are full is not working.  We are eating 275 more calories of food each day than 25 years ago.
This increase in calories is almost no fat and all carbohydrates.
We have increased soft drinks 41% and fruit drinks 35% .
On can of soda/ day = 150 calories x 365 days/ year divided by 3500 calories/pound = 15.6 pounds / year
Current consumption of High Fructose Corn Syrup in the USA is 63 pounds/year/person
Secular trend in fructose consumption
•         1900       15 grams for fructose per day
•         1945       16 – 24 grams of fructose per day
•         1977       37 grams of fructose per day
•         1994       54 grams of fructose per day
High Fructose Corn Syrup – HFCS – was invented in Japan in 1965 Brought to America in 1975
High Fructose Corn Syrup – HFCS is evil because it is so cheap that it has found its way into all food.
We eat 141 pounds of sugar a year per person in the USA
Humans 50,000 years ago consumed 100-300 grams of fiber per day.
Today we consume 12 grams of fiber per day.
Life style intervention
1.       Get rid of all sugary liquids – only water and milk
2.       Eat your carbohydrates with fiber
3.       Wait 20 minutes for second portions
4.       Buy your screen time with physical activity.  You want to watch television for thirty minutes then you have to play outside for thirty minutes
Why is it exercise important in obesity?
•         Because it burns calories
•         Because it improves skeletal muscle insulin sensitivity
•         Because it reduces stress and resultant cortisol release
•         Because it makes the TCA cycle run faster, and detoxifies fructose, improving hepatic insulin sensitivity
Can you name the seven foodstuffs at McDonalds that do not have High fructose Corn Syrup (HFCS) or sucrose?
1.       French fries (salt, starch, fat)
2.       Hash browns (salt, starch, fat)
3.       Chicken McNuggets (salt, starch, fat)
4.       Sausage
5.       Diet Coke
6.       Coffee
7.       Tea

 

As always, thanks for listening.
