I don’t even put 1 teaspoon of sugar in coffee. Black(preferably dark roast) or nothing. But I have seen many put 6+ in coffee. Dunkin Donuts serves that shit routinely whenever someone doesnt specify how much sugar.Ketchup is full of sugar, has 27g per 100g, that's nearly 7 teaspoons of sugar. Low on calories high on sugar. Mayo has hardly any sugar. Better to count the carbs than calories
