I'm debating weather to delete this post, I don't want to offend anyone. Does it come across as offensive or just me, being overwhelmed by the in-laws?
Yes, Chinese food can be extremely healthy when prepared properly. Yes, portion sizes tend to be smaller then our American restaraunts.
I think that normal people aren't like my in-laws.

(Do we all have strange in-law stories?)

(you might need it when I get really into my long rant):
My soapbox,

(please don't think it's a personal attack at you-you are entirely correct I believe for the majority.)
My dh is from China, his whole family is still there. They do consume way too much sodium in general.
When his parents came to visit they were both adding more salt and MSG to everything. MSG comes in a big tub at the asian market and you just buy it by the scoop. And frying everything. They would buy big pieces of pork belly-you know bacon before it's smoked and sliced. They were so annoyed with me for serving them chicken breast and pork loin.
They started shopping and cooking while I was at work so their poor son would have good food. They always picked meet pieces that were more fat then muscle. You can say that's ok because they don't eat that much, they did! They'd buy a 5# chunck of fatty meat and between the 3 of them they'd eat most of it by the end of the meal, fat and all. Clicking their tongues at all the horrible foods I was making their baby eat. (whole grain, low saturated fats, steamed or lightly stir-fried veggies, low fat milk)
It's a big fat myth that Chinese people are healthy because they eat so much healthier then we do, yes, they tend not to eat the processed foods-chips, french fries, cookies, candy, no hydrogenated fats, no high glucose corn syrup. But they do eat a lot of saturated fat, the fry many vegetables before cooking it with a sauce, the sauces are loaded with sugar and msg/salt, even the stuff you get in China made by chinese people for chinese people. Chinese people do have high blood pressure and cholesterol problems, they tend not to have the obesity problems that we have.
They can get by with bad food choices because in general the majority of people haven't picked up the western habits of sitting and eating too much. They generally have to walk or ride bikes great distances-well at least we would conisider it a great distance.

, I need to chill, can you tell this is a touchy subject for me? <wiping foaming mouth> - Deep breath, calm down- think puppies, kittens, butterflies, rainbows. They went home and won't be back for another year.
It could be the vacation mentality when they visit us. But they eat more then I do and they don't gain weight-It's so not fair! Maybe that's why I'm so disgusted about the entire thing.
Things are changing in the big cities, they are getting western junk foods, cars, working in sedintary jobs for long hours. So the obesity rates are climbing and the diabetes rates are increasing. Dh's cousins are starting to have to battle the bulge now, they used to walk almost every where, now they drive and sit in traffic for so long they don't have time to exercise like they used to.
Disclaimer: I'm basing my rant on the few family members I've had the misfortune of trying to feed and the high blood pressure/high cholesterol problems of the many friends who are Chinese in our circle of friends who have the problems with blood pressure/cholesterol.
