Sugar: The Bitter Truth (2009)

It's a 90 minute video, so to summarize:
- US decreased fat in processed food, but compensated with HFCS (corn syrup)
- HFCS contains fructose, which is poisonous in large quantities, which we are now eating (almost half a pound per day per person)
- the additional calories in processed food caused Americans to gain 25 pounds in 20 years
If you drink regular soda with HFCS, then you should switch to one can of cane sugar soda (from Mexico), or one diet can per day. Look at labels and avoid HFCS whenever possible.
You can do a quick reality check on the above by comparing group photos from the 1960s and today - nobody was fat back then, except for Mama Cass.
