More than half of all Americans say they’re trying to cut back on sugar.

But it’s hard to quit something that tastes so good—especially when the brain is hard-wired to love it.

In a recent study from Oregon Research Institutes, sipping a milkshake caused the “reward center” of the brain to light up.

This is the part that floods the body with feel-good chemicals.

The more sugar the milkshakes contained, the more this region of the brain—the same one activated by addictive drugs like cocaine—glowed.

So it’s no wonder that on average we consume double the recommended amount of sugar.

The American Heart Association said women should have no more than 100

calories of sugar daily. That’s six tsp. Men also shouldn’t consume more than 150 calories, which equals to approximately 9 tsp.

But all sugars aren’t created equal when it comes to health.

Those guidelines single out only added sugar, the kind put in during processing and baking.

For foods that contain natural sugars, like fruit and dairy, the beneficial nutrients outweigh the amount of sugar.

It’s also difficult to overeat natural sugars; it’s the ones added to processed foods that sneak up on you.

Until the FDA holds up their end of the deal in producing accurate nutrition labels to call out added the sugar in products, these tips will help to boost your sugar IQ.
