Calories, Protein, Transfat, KCal

Just a quick few questions on nutritional facts in Japan.

KCal I've noticed as a measurement on some food in Japan. I really am not sure what these mean and could not find it on the forum with a search.

Are all foods required to have a nutritional data sheet?

I can't remember and don't have any food here at home, but does food tend to be measured by serving size as well in Japan?

Kcal = kilo calorie = 1000 calories
1 calorie = the amount of energy required to raise the temperature of one gram of water by 1 ﾂ≫?ｹC (Celsius). https://en.wikipedia.org/wiki/Celsius
1 cal = 4.184 J

Are all foods required to have a nutritional data sheet?

No, it is not mandatory, though many food packages show basic nutrition facts.

It really depends. Usually they show the nutrition facts for 100g, sometimes serving size (for example, a small carton of vegetable juice of 250ml shows nutrition facts for one carton).
Some cereal packages I checked at suparmarkets show both the facts for 100g and that for a service size (=40g or something) as well.

One thing you should probably know is that a calorie is different than a food Calorie. A food Calorie is 4184 joules, or 1000 calories. So a Calorie is a kilo calorie. These are the type of Calories you see in foods. It can be pretty confusing .

Ooooh, ok thanks for explaining things guys. The problem is I'm on a careful calorie watch right now as I try to cut down some fat and then build up some muscle before I leave (lost 18 pounds or so gained about 22 pounds of muscle) and I intend to continue of course after I arrive in Tokyo. The problem is I needed to know how to manage calorie and nutrition intake afterwards.

So... if I aim for 1500 kcals will this be the same as 1500 food calories?
