Bird Nest Soup (large Version)
She told me although she couldn't say bird nests had no nutrition value but 100% sure that it must have been wildly exaggerated by the companies which produce the associated products or the salespersons who sell them.

Last February when traveling to Southern Thailand's Hatyai the city is famous for bird nests, I tried my luck for the first time at a specialty products shop. As shown in the photo above, such a bowl of bird nest soup cost me a whopping 450Baht, or ~12 US dollars.

However, there really is no scientific evidence to justify any nutritional or health claims made for it.
In fact, it can be downright dangerous, as environmental contamination has turned up in bird's nest soup in Vietnam from arsenic. A Vietnamese man was poisoned from arsenic intoxication after consuming bird's nest soup! This was written up in the American Journal of Medical Sciences in April, 1999.
Oh, I probably would never buy expensive bird nests products again!
