I think its harder to maths out. It's pretty easy to separate people into three groups of smokers. 0 smoking, 5-10 smokes a day, 15-20 smokes a day. Many people are very very consistent for years. How does that work for sugar. You can have soda for not soda drinkers. But much added sugar is hidden. How many G of sugar do you eat per day? How many did you eat a month ago? 5 years ago? 10 yeas ago? Have you managed to eat the same G of added sugar over a long time?
