They're also using carotenoids for coloring. Carotenoids are basically pigments which can be used by our body as vitamin A source.

When I read nutrition labels on lactose-free milk, it still has a lot of sugar in it. Other than lactose, what other sugars are there??

Cheese is delicious! Ask Jerry if you don't believe ;)

[rfldss]

don't they use beta-carotene to colour cheese? I'm pretty sure cheddar is coloured with it, not annetto.

In the voice-over narration, I find the cadence and intonations used, as well as the specific grammatical forms used here are highly conducive to non-retention of the information. Why so many parenthetical expressions? Why the bouncing up and down of the voice, skewing the emphasis in 'weird' ways? It appears the producers do not think the subject itself is interesting enough, and they have to punch it up with perky BS to try to make it more interesting. Why not play it straight and give the information in ways it can be remembered directly, as science? Very disappointed in this presentation.

Dairy is so fucking scary!!! For our health. For the mothers and the babies enslaved by the dairy industry. For our planet. I’m so happy since I’ve broken my cheese addiction.
