How Can People Know How Many Calories Food Has?
Posted by Zolly | Under Nutrition Saturday Feb 27, 2010i read the labels on foods and webpages etc, nutrition facts, this has ## calories, that has xxx calories, how can they know exactly how many calories a food contains?
well the nutritional facts on the back should say serving size: (there should be a number here like 3 or 4) and you multiply the number of calories by that number
like
serving size: 3
calories: 140
140*3= 420
that food/drink has 420 calories in it
XD i had to laugh at 420
carry on.
