its important to know there are different types of 'salts' and 'sugars' too
take the salts/brines used in processed meat is not the same salt you sprinkle on your fries
the salts/brines used in preserving meats is far worse.
But what about the sugar?
I don't think that there is any "good" sugar... All kinds affect negatively our body. Even the sugar that exists in fruits in not healthy if you consume a lot of "sweet" fruits.
