Pure maple syrup would be much healthier for you than drinking a cup of soda.
But even when you drink just one cup or one can of soda per day it's not all that harmful but it's still not the healthiest drink in the world.
Soda is not healthy really but drinking soda in moderation won't harm your health.
You have to drink a lot of soda and no water or other healthy drinks before the soda becomes a problem.
But drinking a cup of maple syrup is okay too and I do it sometimes.
I have a cup of maple syrup with some waffle sticks so I can dip the waffle sticks in the maple syrup to eat and then I drink the leftover maple syrup.
I still need a glass of water or orange juice or coffee or something to wash the maple syrup down though otherwise I begin coughing.
