Interpret the labeling

Hello.I have "another" doubt.In a fried tomato boat of 215 g.He says for every 100 g.contains
Energy value = 74 kcal
Carbohydrates = 10.5 g.
of which sugars = 8.5 g.
What does everything mean?
Thank you
P.S.Can I take 10.5 g.hc = 1 ration?

Yes, that's.You don't have to be ultra precise.1 ration are about 10 gr of carbohydrates, and in this case you get it with 100 gr of that boat.That is, the whole boat is about 2 portions.

The fact that it has most sugars (8.5 gr) simply gives you a clue that those carbohydrates will enter quickly, that is, that food has a high glucemic index.But calculate the rations with the total amount of carbohydrates on the label.Forget the calories!For what you want, just look at the carbohydrates.The sugars will give you a track of rapid tea will enter.

All the best

1000: 10.5 = 95.3g
95.3g of that tomato is a ration of HC.
