The Journal of American Medical Association reports that high sugar consumption results in worse cholesterol levels. Added sugars are table sugar (sucrose) and high-fructose corn syrup, found in processed foods and sodas.
The study states that the average person eats a diet where almost 16 percent of the calories come from added sugars. That's one of every seven calories consumed. Since added sugars are empty calories, which means they offer nothing nutritionally, one of every seven calories the average person eats has nothing good in it. But it can contribute to unhealthy weight gain.
The study showed that added sugars increased triglyceride levels, but not LDL (bad) cholesterol.
Dr. Shantanu Nundy says, "But, to me, the case against added sugars is adding up. At the least, we know that added sugars aren’t doing anything good for our health — they are simply empty calories. But we are increasingly appreciating that besides adding calories they are having other harmful effects on our health. It’s about time that we subtract added sugars from our diets."
