Why do Americans tend the have more health problems than Australians?

One thing the unhealthiest countries all have in common is that they, on average, work more than 34 hours per week.  The US is number ten on that list, but compounds its problems with no mandatory vacation time and an average of only 15 days of vacation.  This is further multiplied by a fairly unhealthy average diet with high sodium, saturated and trans fats, added sugars and refined grains.  It is a byproduct of being the wealthiest country in the world - that expensive but nutritionally worthless foods became popular.  High fructose corn syrup is a big problem because it packs more sugar into products that do not need it and triggers an blood sugar spike that causes craving for more food and sugars.  Aspartame sucks too.

The US is the 51st unhealthiest country in the world, Australia is the 14th healthiest.

We love junk food. 

Do you have any proof of that assertion? Australians have a better rate of carcinoma, I know. the typical lifetime in Australia is slightly higher- possibly because the US features a higher poverty rate due to the shortage of state help.

Maybe Australians don't live as long. LOL.

Too much french fries , hot dogs and KFC 

Have you ever been to the US and seen the size of the food portions? An entrée is bigger than an Australian main course.

And mayonnaise being spread on everything can't be helping. 

They can afford to buy more KFC.

Since most animals in Australia are deadly, including humans, perhaps they don't live long enough to experience health problems.

I normally don't do anything with women unless I'm fornicating with them. So you shouldn't talk any more, unless you wanna you know.

Maybe we have better doctors and the health problems get reported.
