Coffee is one of the healthiest beverages you can drink.

It contains antioxidants that protect heart health and is associated with a decreased risk of type 2 diabetes

Coffee also contains caffeine, which can improve mental and physical performance while increasing metabolic rate 

On the other hand, the high sugar content of flavored low-fat coffee drinks can negatively affect health.

For example, a 16-oz (450-gram) nonfat mocha drink has only 2 grams of fat but a whopping 33 grams of sugar. That’s 57% of total calories 

Not only does this beverage provide a hefty serving of fructose, but it’s in liquid form, which seems to be especially harmful to health 

Liquid calories aren’t as satisfying as calories from solid food. They promote a higher daily calorie intake that may lead to weight gain 

BOTTOM LINE:

Adding sugar to coffee transforms a healthy beverage into one that may lead to weight gain and disease.
