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.

  • Mr. Lustig should give a lecture on TED.

  • There's a lot of people bashing the consumption of fruit based on the teachings in this video. But at 1:13:48 the lecturer himself says fruit is OK! It's the UNNATURAL intake of sugar in man made PROCESSED foods with ADDED sugar that is the issue at hand. Unnatural is unhealthy.

  • @BOX5500 SUGAR IS SUGAR ie. One fructose and one glucose molecule.

    Fruits contain numerous sugars, but are not high in fiber. If your goal is to reduce sugar intake, then reduction of fruits, though it seems odd, is the way to go (especially for weight reduction, diabetes, etc.). Paleolithic diet is mostly fiber (ground crops, ie. vegetables) and protein (meat). If you are taking in sugar, its best with some fiber (which fruit gives), but processed sugar foods are generally free of fiber!

  • Thank You So Much for your enlightening me and my family. Thank You for you honesty and integrity!

  • I'm glad I watched this video. Thanks to Prof. Lustig.

  • @mightybaboonking You're talking about changing something from it's natural state. No one suggested you juice "loads of sweet grapes" and drink it as your "primary source of calories". Of course that is going to cause problems. Drinking too much pure water will also kill a person. You should eat grapes until you're comfortably full and then you will not eat excess sugar, but certainly not every day. Eat a variety of fruits, vegetables, grains, nuts and seeds.

  • @sp1nm0nkey The Dr. said otherwise. Where's your argument?

  • This is theory and conjecture. His science is very flimsy? Making fructose the villain? I think not. What fructose is a six month old getting?
