Don’t Eat Foods Containing Fructose!

Professor Robert H. Lustig talks about the dangers of consuming the sugar fructose that has been imposed on us by the food industry in this 90 minute lecture. You can download his handout [PDF] or even listen to it [Audio].

I’ve summarized most of the points he made, so that it may be easier to understand or remember:

What is fructose?

Fructose (in the form of corn syrup or sucrose) is a type of sugar (carbohydrate) that has replaced glucose “the energy of life” in many processed foods.

In which foods?

Fruit juice, sauces, ketchup, soda drinks, Pepsi, Cola, bread, candy, and many others. It’s everywhere. Especially in “diet” and “low-fat” foods. Read the labels.

What’s bad about fructose?

Inhibits leptin, the hormone responsible for making you feel ‘full’. The brain still thinks it’s starved hence more eating. It also doesn’t trigger insulin, so (similar to the toxin alcohol) only the liver can metabolize it while risking liver disease. It eventually causes a metabolic syndrome: obesity, type 2 diabetes, lipid problems, hypertension and cardiovascular disease.

Why is it in our food?

Pure economics: It’s cheaper, more abundant, and sweeter than glucose. In combination with the removal of fiber, foods get longer shelf life and cook faster; fast food.

What should I do?

  • Only drink water, fresh milk and fresh squeezed fruit juice.
  • Eat carbohydrates with fiber (like fruits).
  • There is no cure except changing your own eating behavior.
  • Promote awareness by telling your friends, relatives, and people you know.

What good is fiber?

  • Reduce intestinal carbohydrate absorption rate.
  • Increases speed of intestinal transit inducing the feeling of being ‘full’.
  • Lowers absorption of some free fatty acids in the colon and suppresses insulin (unfortunately, that also means more gas).

Exercise is NOT for burning calories!

  • Improve insulin sensitivity
  • Reduce stress and cortisol release
  • Higher energy expenditure = Feeling good
  • Detoxifies fructose

Also worth mentioning: Cola contains high amounts of salt that is masked by high fructose. Salt makes the body loses water so you become thirstier. It’s made to make you drink and eat more.

  1. I have heard this before, but the breakdown of this information is insane! So basically we become thirstier and hungrier and never really satisfied just because they are using a cheaper chemical to make better sales. It always revolves around money.

    I really need to lose weight, I have been putting it off but I need to start somewhere.

    Didn’t know youtube let you upload more then 10 minute videos!

    Thanks for the great post! More posts!!!!!!!

  2. Wow that was shocking but very enlightening! Thank you very much for sharing it.

    Having read this, i have to admit that it really worked for me even though i just found out about this article.
    I was out the country for 10 days, and all i’ve been eating was fruits, vegetables, fresh fruit juices and water and obsoletely 0 soda consumption or even junk food. And i really felt healthy, light and most importantly full! I never felt the need to eat more or simply, felt hungry! and i kinda liked this life style as it has a deep impact on the mental health as well.

    So, thanks for sharing it again :)

    • If you actually watched the video, it points out that “low fat products usually contain a large amount of sugars and carbs”. So even if the food didn’t contain fat, the high amounts of excess carbs eventually turn into fats anyway.

  4. i cant thank you enough ! will never touch fast food again ,,, your information can chane peoples lives…thank you

  5. I actually live with Fructose intolerance. It is a pain in the butt when its first presented. I would like to give everyone the challenge of no fructose. Fructose is in almost everything. There are 2 things that I have a hard time keeping out of my diet. Onions (any type) and Lettuce (every type). This means that I can’t have anything premade since Onions are a main ingredient. Lettuce is the hardest. This means no salads unless its spinach salad. It is also in 99% of breads. The only prepackaged bread I can have is Rye bread. This means no burgers, hot dogs and other fast food products. This doesn’t mean that you need to cut everything that has fructose in it. It means in moderation (eg. small glass of O.J.) I will say this, It was the best choice i ever made to take it 100% out of my diet. I cut my portions but it made me drop 10lbs instantly and I have lost a total of 60lbs.(without physical activity) I have converted my family into a fructose free diet and they have lost weight as well and they feel much healthier. Thanks to living in Canada there are still options. In the USA I was unable to eat most foods. I believe this will help most ppl lose the tiny extra weight that isn’t needed.
