Typical Indian cooking uses turmeric in pretty much everything. I wouldn't be surprised if daily consumption of turmeric is very close to the figures you mentioned.
My kitchen medicine for running nose, soar throat is hot milk with turmeric. Works for me most of the times.
I've been mixing it through my oatmeal, together with chilli-pepper and black pepper, a bit of cardamom, and a teaspoon of real cinnamon (the non-cumerin kind). While it feels like it works, I know that the placebo effect is probably much stronger than any real effect these foods have. Still, a placebo effect is still a real effect on my mood, so that's still a kind of health benefit I guess. If nothing else the spices help me wake up!
Tangent regarding health food fads: these days I mainly use nutritionfacts.org[0] to determine which of those are actually supported by the latest nutrition research. It is the only health food/diet website that I know of that directly cites nutrition research and continuously scours the latest papers for new findings - sources are always linked, and quotes are directly lifted from the papers with no modification (so less likely to suffer from "stronger or opposite of what the paper actually says"-shenanigans often seen elsewhere).
Some of the other things I tried out based on that website have too big of an effect to just be placebo: adding blue-berries to a meal really reduces sugar rushes/crashes in the hours after it[1]. Taking a table spoon of freshly broken flax seeds[2] does a lot to counter the rise in blood pressure due to my ADD medication (I measured it, plus I feel a lot less discomfort in my chest area and less jittery).
Last time I mentioned that website here, it was in a discussion of which diets are healthy. Ironically, it was the only comment in the discussion that attracted multiples downvotes without explanation, while everyone else was sharing their unsourced opinions.

Granted it's probably due to alcohol and tobacco but curry probably won't save you from cancer.
