If you're consuming a modern diet, then chances are you're eating WAY too much sugar.  Sugar is hidden in most processed or manufactured foods so when you add even more from a sugary dessert: you could really be harming your health.

And it's not just obesity that's the problem.  Too much sugar consumption can actually kill you!  I was just reading this article by Harvard Medical School and they said:

Since your body digests these foods slowly, the sugar in them offers a steady supply of energy to your cells. A high intake of fruits, vegetables, and whole grains also has been shown to reduce the risk of chronic diseases, such as diabetes, heart disease, and some cancers.

Consuming too much sugar

However, problems occur when you consume too much added sugar — that is, sugar that food manufacturers add to products to increase flavor or extend shelf life.

In the American diet, the top sources are soft drinks, fruit drinks, flavored yogurts, cereals, cookies, cakes, candy, and most processed foods. But added sugar is also present in items that you may not think of as sweetened, like soups, bread, cured meats, and ketchup.

The result: we consume way too much added sugar. Adult men take in an average of 24 teaspoons of added sugar per day, according to the National Cancer Institute. That's equal to 384 calories.

“Excess sugar's impact on obesity and diabetes is well documented, but one area that may surprise many men is how their taste for sugar can have a serious impact on their heart health,” says Dr. Frank Hu, professor of nutrition at the Harvard T.H. Chan School of Public Health.

Impact on your heart

In a study published in 2014 in JAMA Internal Medicine, Dr. Hu and his colleagues found an association between a high-sugar diet and a greater risk of dying from heart disease. Over the course of the 15-year study, people who got 17% to 21% of their calories from added sugar had a 38% higher risk of dying from cardiovascular disease compared with those who consumed 8% of their calories as added sugar.

“Basically, the higher the intake of added sugar, the higher the risk for heart disease,” says Dr. Hu.

I'd highly recommend you read the whole article over at Harvard's site here:

Even if you think you're not eating much sugar, I highly recommend that you really read all your labels and calculate your actual daily sugar consumption.  I bet it will surprise you!
