Your favorite beverage choices could be silently damaging your heart, warns cardiologist Dr. Evan Levine, who identifies four common drinks that may pose serious risks to cardiovascular health.
At a Glance
- Starbucks Frappuccinos contain high levels of caffeine and sugar that can be dangerous for people with existing heart conditions
- Excessive alcohol consumption can lead to alcohol cardiomyopathy, a serious heart condition that weakens the heart muscle
- Regular soda consumption contributes to weight gain, increased triglycerides, and diabetes risk—all factors that harm heart health
- Energy drinks pose significant cardiovascular risks due to their high caffeine and sugar content, with documented cases of cardiac events in young consumers
Understanding Caffeine’s Impact on Heart Health
Caffeine, a common ingredient in many popular beverages, has complex effects on cardiovascular health that vary widely among individuals. It stimulates the central nervous system, releases fatty acids from adipose tissue, and increases urination which can lead to dehydration. While moderate coffee consumption—defined by the FDA as 4 to 5 cups daily for healthy adults—is generally considered safe, people with certain health conditions may need to exercise caution.

Sensitivity to caffeine’s effects can vary significantly based on individual health factors and medications. For those with heart arrhythmias or high blood pressure, even moderate caffeine intake may exacerbate symptoms. Pregnant and lactating women are advised to limit consumption to 2-3 cups per day, while the American Academy of Pediatrics recommends children and adolescents avoid caffeine and other stimulants entirely.
Sugary Beverages and Cardiovascular Risk
Dr. Evan Levine specifically warns against Starbucks Frappuccinos and sodas due to their dangerous combination of high sugar and caffeine content. These beverages can cause rapid spikes in blood sugar and insulin levels, placing additional stress on the cardiovascular system. Regular consumption of sugar-sweetened beverages has been linked to increased risk of obesity, type 2 diabetes, and metabolic syndrome — all significant risk factors for heart disease.
Sodas are particularly problematic as they contribute to elevated triglyceride levels, which are linked to atherosclerosis (hardening of the arteries). Research shows that consuming just one sugar-sweetened beverage daily increases the risk of developing coronary heart disease by up to 20%. The empty calories in these drinks also contribute to weight gain without providing nutritional value, further compromising heart health over time.
The Energy Drink Danger
Among the beverages Dr. Levine identifies, energy drinks may pose the most acute risk to cardiovascular health. These products contain alarming levels of caffeine along with other stimulants like guarana and taurine, creating a potentially dangerous cocktail for the heart. The caffeine content in some energy drinks can reach up to 300mg per serving—equivalent to nearly three cups of coffee.
The dangers of energy drinks are not theoretical. A case highlighted by Dr. Levine involved a young woman who suffered a fatal heart attack after consuming energy drinks. Medical literature has documented numerous cases of cardiac arrhythmias, myocardial infarction, and sudden cardiac death associated with energy drink consumption, particularly among younger adults with undiagnosed heart conditions.
Alcohol’s Complex Relationship with Heart Health
The relationship between alcohol and heart health presents a nuanced picture. While some studies suggest moderate consumption may be associated with slightly increased levels of “good” HDL cholesterol, excessive drinking clearly damages the cardiovascular system. Dr. Levine warns that heavy alcohol use can lead to alcohol cardiomyopathy, a condition where the heart muscle becomes weakened and cannot pump blood efficiently.
Moderate drinking is defined as one drink daily for women and up to two for men. However, certain individuals should avoid alcohol completely, including those with heart rhythm abnormalities, heart failure, or a history of hemorrhagic stroke. For those who do consume alcohol, it’s important to recognize that its high calorie content can contribute to obesity and related health issues, potentially offsetting any modest cardiovascular benefits.
Making Heart-Healthy Beverage Choices
While certain beverages pose risks to cardiovascular health, others can be part of a heart-healthy lifestyle. Water remains the ideal choice, helping maintain proper hydration without added sugars or calories. Unsweetened tea, particularly green tea, contains beneficial antioxidants that may support heart health. For those seeking alternatives to alcoholic beverages, grape juice provides many of the same antioxidants found in red wine without the associated risks.
Consulting healthcare professionals about individual caffeine and alcohol tolerance is essential, as sensitivity varies widely. Those with existing cardiovascular conditions should be particularly cautious about their beverage choices and may need to avoid certain drinks entirely. By making informed decisions about what we drink, we can take meaningful steps toward protecting long-term heart health.
