Video Notes: Sugar, The Bitter Truth by Robert Lustig, MD



Ranked by sweetness:
Fructose (lab) - 170
HFCS - 120
Sucrose - 100
Glucose - 74
Lactose (milk sugar) - 15

HFCS = sucrose (table sugar)

HFCS and sucrose are poison. Both contain fructose. 
  • Fructose 7x more likely to cause browning of blood vessels than glucose. 
  • Fructose does not suppress hunger hormones - we eat more even when full. 
  • Eating too much fructose cause:
    • Type 2 Diabetes
    • Heart attack
    • Hypertension
    • Obesity

Juice contains sucrose. 

Low fat food usually contain more HFCS to improve taste. 

LDL can be broken down into 2 types - one good one bad. Low triglyceride (1+) and high HDL (1.5+) suggest more of good LDL. 


Fast food = fibre less food, to cook faster and last longer. 

Compare:

120 kcal glucose (2 pcs of bread)
  • 96 kcal use by body.
  • 24 kcal reach the liver.
  • glucose turn into glycogen in liver, but is harmless.
  • tells brain that you are full.
  • ~1/2 kcal turn into VLDL (cause heart disease, obesity), but not so bad.

120 kcal ethanol
  • 24 kcal absorbed by body and brain
  • 96 kcal reach the liver - damages liver
  • a lot more VLDL created

120 kcal sucrose (a glass of orange juice, sucrose = 1/2 fructose + 1/2 glucose)
  • 60 kcal fructose (not used by other cells in body, all go to the liver) + 12 kcal glucose reach liver
  • a lot more VLDL created
  • produces chemicals that stops telling brain to stop eating => vicious cycle

fructose => uric acid up => gout, hypertension, high blood pressure

Chronic fructose exposure cause same problems as chronic ethanol exposure


Exercise is good, not for burning calories. For reducing stress, appetite goes down. 

Fiber is good. Wherever there is fructose in nature, there is fibre. That’s why fruits are ok. Fiber tells brains that we are full earlier.


Drinking chocolate milk is like drinking a cup of milk + 1/2 a cup of orange juice.



 Coke is 10.5% sucrose.

The earlier kids are exposed to sweet, the more they are going to crave for it later.
