According to Michael Moss in his book, Salt Sugar Fat, most food companies use sugar to engineer processed foods to achieve a 'bliss point' which appeals to consumers so greatly, they'll purchase the product repeatedly. In a can of soda, this may require as many as nine teaspoons of sugar, which suggests that the bliss point and health are inversely correlated...
Actively avoiding sugar is a good pursuit. Cook fresh meals at home, make your own desserts and restrict the sugar content, and skip sweetened beverages or dilute them with water if they are a big part of your life. Sugar causes inflammation which is the breeding ground for many illnesses, but it can be controlled with a bit of discipline and effort!
