How much sugar is too much for one day?

over 40 grams Any sugar is not good for you. If you have sugar in your tea or coffee you are also eating hidden sugars in things you eat so it really adds up fast. We already know candy, pop, etc., all have sugar in it, but it's the other products we buy such as Ketchup, jams,, etc., (that can say natural) but if you read the label there is sugar in it. There is absolutely no reason jams or many other foods need sugar. Diebetic jams are sweetened with Apple juice that contains a natural sugar.
