Sugar: The Bitter Truth


Watch “The Skinny on Obesity” with Dr. Lustig:
Robert H. Lustig, MD, 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.

  1. Well, you can also say that kids these days are spoiled. When I was a kid, I didn't get much candy or pop. I didn't get free lunches at school. Let's see, Oatmeal for breakfast, a peanut butter sandwich and an apple or orange for lunch, and dinner was dinner, but no desert. Desert came on birthdays only. Halloween was minimal. Christmas was minimal for treats. I guess I owe not being "fat" to my mom, who freaked out when I had 4 cavities when I was 5 or so. That was it, no more sugar. I was a bean pole then. Now, I still don't have much sweets or pop because I never really did. I like very dark chocolate, but that's as far as the sugar goes. I'm trying to make sure my kombucha is properly done too, so there isn't much sugar left. An occasional cookie passes my lips, but I control that too. Nobody is perfect I figure.
    Anyways, great presentation. That's the truuuuthppphhh.

  2. this lecture is 1.5 hours long and at times hard to understand (may even appear to be boring) BUT………do we not spend endless hours to see a doctor, stay in hospitals, wait for medication at the pharmacy? Do we not spend hard earned money for stuff that makes us sick (often unknowingly) and forces us to spend all those hours "getting healthy" again?

    I would like everyone who reads this to motivate you to set aside this hour+half and listen/absorb deeply what this Professor of Pediatrics is trying to teach us. I know, you know and probably everyone knows that sugar is bad for us.

    BUT……..this lecture takes it to the next level. I am glad I "suffered" through the entire thing. I WILL NOT EVER LOOK AT FOOD THE SAME WAY. It deals with the chemistry, statistics, medical information, historical knowledge, corporate/business info, specific product details, eating habits, and references to specific populations (sports, students, small children, age groups, ethnic issues).

    Don't give up, it is interesting to the very last minute. I was aware of a lot of things discussed. The one fact that shocked me most, was the information about baby formula and skyrocketing obesity numbers for 6-month old babies and eating habits during pregnancy. I hope that my little comment motivated you to listen and forward this post.

    (I found the references mentioned at the lecture's tail end helpful to give all this information credibility)

  3. We did not have 30 years of nutrition knowledge. Since the 1970's we had the same scientists funded by the same people producing the same false crap for years so we can all feel good about eating so many fucking carbs.
    This is no different than the tobacco industry. Same law firms.
    Guess where they are now? Plastic companies. Enjoy that BPS, it's way worse for you than BPA (allegedly).
    I'd be really curious what industry they'll go to next.

  4. Doctor Lustig is brilliant. Speaks the truth. This and the similar lectures must be a requirement to watch and study in every school, college and University In this day and age, all food is contaminated. Supermarkets and convenient stores are selling poisonous foods. medications should be abolished as well.I am not even mentioning fast food establishments. The Question is, how munch of fruits can and should we eat? Fruits have the fructose. Fruits are suposedly healthy and nutricious. Glucose and fructose are not . What about vegetables like Patatos and corn? Both are earth products and should be healthy. Both however, have bunch of carbs which are converted into a glucose.

  5. Doc, you lose credibility when you go political. How dare you try to blame one person. What is wrong with you? Stick with science, buddy, and keep your political opinions to yourself. Nobody wants to hear it, we're sick to death of it. Pffft.

  6. This satanic idiot pushing moronic BS
    fact is Margarine is 3x worse for you than butter
    and artificial sugar like Aspartame is outlawed in almost every country in the world… because they know it causes cancer,
    anyone you know have breast cancer? they like the diet soda, artificial sugar.. don't they?

  7. A few points:
    Fruits and vegetables naturally have variable ratios of glucose to fructose.
    For example: the sugar from cabbage is almost completely glucose, while the sugar from an apple will contain a significantly higher amount of fructose. Similarly, the sugar in a carrot is almost completely in the bonded form of glucose and fructose: sucrose.
