Energy and Nutrient Compositions of Foods

I've used the tool on some of the main components of my recorded diet.

	Pow, char siew, steamed
Energy (kcal)	363
Protein (g)	13
Total fat (g)	15
Saturated fat (g)	5.5
Dietary fibre (g)	1.7
Carbohydrate (g)	45
Cholesterol (mg)	23
Sodium (mg)	473
Sugar (g)	N.A
Calcium (mg)	23
Iron (mg)	1.08
Vitamin C (mg)	N.A
Trans fatty acids (g)	N.A

Energy (kcal) Protein (g) Total fat (g) Saturated fat (g) Dietary fibre (g) Carbohydrate (g) Cholesterol (mg) Sodium (mg)

Bun, pizza, baked 224  9  9  4.4  2.5  27  24  486

	Vegetables, mixed, braised
Energy (kcal)		30
Protein (g)		1
Total fat (g)		2
Saturated fat (g)		0.7
Dietary fibre (g)		2.1
Carbohydrate (g)		2
Cholesterol (mg)		0
Sodium (mg)		116
Iron (mg)		0.61
Vitamin C (mg)		11

I guess the results are pretty expected. It appears that one serving of pizza has less energy than a serving of char siew pow. However, to tell the truth, I don't derive any meaning in these nutrients analysis. I doubt if people will check the nutrients composition before they eat something, or if the nutrients composition will affect their decision whether to eat it or not. It is certainly more meaningless to check the nutrients composition after eating. After all, I am not even sure what one serving is, and so are many members of the public. Thus it is even harder to judge if the amount of energy shown is the amount that we have consumed.
