A safe magnesium dose ranges from 300 mg to 500 mg. Too much magnesium can lead to loose stools or diarrhea. If you find yourself running to the bathroom to prevent an accident you could well be getting too much magnesium.
Australians eat a great variety of food, but some of the more traditional meals could include roast meat (e.g. lamb and beef, both of which are very popular) and vegetables. Other favourites are meat pies, sandwiches (including vegemite) and a variety of baked or fried foods.
Pretty much all Asian foods are famous in Australia. If you go to Sydney, you will notice that every second restaurant is Thai. And there is pretty good representation by Vietnamese, Chinese, Korean and Indian as well. Melbourne on the other hand has had all of its Kebab places replaced by Japanese Sushi bars.
