Added Sugar May Harm the Heart More Than Cholesterol, Studies Reveal

New research reveals that added sugar may hurt your heart more than cholesterol. Scientists discovered that people who got over 10 percent of their daily calories from added sugar had a 30 percent higher risk of dying from heart disease. Those consuming 25 percent or more nearly tripled their risk. The connection stayed strong even after considering cholesterol and blood pressure.
Experts warn that we have been focusing on the wrong enemy for too long. While cholesterol matters, sugar may be doing far more damage quietly. In fact, dietary cholesterol increased heart risk by only about 10 percent, much less than added sugar. This new evidence challenges decades of advice that centered mainly on cutting fats and eggs.

Why sugar poses a bigger threat

Added sugar affects the body in many harmful ways. It spikes blood glucose levels, promotes weight gain, and raises triglycerides. These changes can inflame your arteries and stress your heart over time. For example, drinking just one sugary soda daily can push you toward a higher risk of heart attack or stroke. Therefore, experts recommend replacing sugary beverages with water, tea, or fresh fruit juices without added sugar.

A shift in heart health advice

Recent studies from the American Heart Association and Oxford University confirm that sugar harms metabolism more than previously thought. They suggest that cutting added sugar could lower your heart disease risk more effectively than reducing fat or cholesterol. In addition, limiting sweets, soft drinks, and processed snacks can also support healthy blood pressure and better energy levels. The message is clear — your heart benefits more from less sugar, not just less fat.
