We often associate fruits, greens, and low-fat foods with good heart health. But a leading U.S.-based cardiologist, Dr. Dmitry Yaranov, popularly known as @heart_transplant_doc on Instagram, has warned that even the most celebrated “healthy” foods—like bananas, spinach, and grapefruit—can have unexpected consequences if not consumed with awareness of one’s medical conditions or medications.
In his latest Instagram post titled “The ‘Healthy’ Foods that Can Quietly Hurt Your Heart,” Dr. Yaranov emphasized that “it’s not that these foods are bad; it’s that your heart, kidneys, and medications change how your body handles salt, potassium, and metabolism.” The post, which has gone viral for its counterintuitive revelations, aims to educate people about how diet interacts with individual physiology rather than fitting into a universal definition of “healthy.”
The Surprising Side of Everyday Foods
According to Dr. Yaranov’s post, bananas and spinach, though rich in nutrients, contain high levels of potassium, which can be risky for individuals with kidney issues or those on specific heart medications like spironolactone or ARNI. Excess potassium can build up in the blood, leading to potentially dangerous imbalances.
He also flagged grapefruit as a hidden risk. The fruit, while packed with vitamin C, can interfere with how the liver metabolizes certain medications—especially post-heart transplant drugs—causing drug levels to rise beyond safe limits.
Similarly, soy sauce, a staple in many Asian cuisines, is “pure sodium,” as Yaranov noted. A single sushi night, he warned, “can mean two pounds of fluid retention and shortness of breath the next day.”
Everyday Ingredients with Unexpected Impacts
The cardiologist also shed light on liquorice, an ingredient that often hides in teas and herbal supplements. Real black liquorice, he explained, can raise blood pressure and lower potassium, posing a dual threat to heart patients. Meanwhile, alcohol, he stated bluntly, acts as a “direct cardiac toxin,” and in some cases, “it’s the reason the heart got weak in the first place.”
His larger message, however, was not one of fear but of understanding. “Food isn’t good or bad,” he wrote. “Food interacts with your labs, your meds, your heart. Know your body. Know your numbers. Stay ahead of this.”
A Doctor Who Simplifies Heart Health
Dr. Yaranov is the Medical Director for Advanced Heart Failure, Heart Transplant, and Mechanical Circulatory Support in the U.S., specializing in advanced cardiac care and post-transplant health. Dr. Yaranov’s reminder serves as a wake-up call for the health-conscious generation that often equates “natural” with “harmless.” Even the most wholesome foods can carry risks when taken without context. As he underscores, health is never one-size-fits-all—it’s about balance, awareness, and personalization.
For anyone on medication or managing heart conditions, the message is clear: consult your doctor, understand your body’s needs, and don’t assume every ‘healthy’ food is healthy for you.
