Sugar in Fast Food

One thing confused me about the Super Size Me movie:  Why did the doctors attribute Morgans sickly state to the high fat content in the food that he was eating?  What about all of the sugar and the toxins?  Did that have nothing to do with his state?  Just about everything that Morgan ate contained sugar, however, the soda that he drank probably had more sugar than all of his meals put together in a day!  He ate the super size meals which means the soda was approximately a 42 ounce cup.  Below I listed the ingredients and the sugar content (highlighted) in one of his dinners.

Big M**®:
100% Beef Patty, Big M** Bun, Pasteurized Process American Cheese, Big M** Sauce {Soybean oil, pickle relish [diced pickles, high fructose corn syrup, sugar, vinegar, corn syrup, salt, calcium chloride, xanthan gum, potassium sorbate (preservative),  spice extractives, polysorbate 80], distilled vinegar, water, egg yolks, high fructose corn syrup, onion powder, mustard seed, salt, spices, propylene glycol alginate, sodium benzoate (preservative), mustard bran, sugar, garlic powder, vegetable protein (hydrolyzed corn, soy and wheat), caramel color, extractives of paprika, soy lecithin, turmeric (color), calcium disodium EDTA (protect flavor).}, Lettuce, Pickle Slices, Onion.  

French Fries:
Potatoes, vegetable oil (canola oil, hydrogenated soybean oil, natural beef flavor [wheat and milk derivatives]*, citric acid [preservative]), dextrose, sodium acid pyrophosphate (maintain color), salt. Prepared in vegetable oil (Canola oil, corn oil, soybean oil, hydrogenated soybean oil with TBHQ and citric acid added to preserve freshness). Dimethylpolysiloxane added as an antifoaming agent.

C**a Cola:
Carbonated Water, High Fructose Corn Syrup, Caramel Color, Phosphoric Acid, Natural Flavors, Caffeine

The sugar is measured by grams.  The burger has about 9 grams of sugar.  Morgan had the super sized fries and the nutrition content for that wasn't available, however, the large french fries have 0 grams of sugar.  Don't be fooled though, there is sugar in the fries as you can clearly see above.  According to the C*ca C*la website, 8 ounces of their soda (the original) contains about 27 grams of sugar.  The large sodas in Super Size Me were 42 ounces which means he ingested about 135 grams of sugar (minus a few grams for ice) in that one sitting.  That is somewhere between 7 and 10 teaspoons of sugar in one large cup of soda.  Whoa!
