Heart disease remains one of the leading health concerns worldwide, affecting millions of people every year. While many people focus on obvious factors such as smoking, lack of exercise, or high blood pressure, some medical experts believe another contributor may be hiding in plain sight: refined carbohydrates.
One heart surgeon in particular is encouraging people to take a closer look at the foods they consume on a daily basis.
Dr. Philip Ovadia, a veteran heart surgeon who has spent years treating patients with serious cardiovascular conditions, recently shared concerns about the potential role refined carbohydrates may play in chronic inflammation and the development of arterial plaque.
According to Dr. Ovadia, the issue is not simply about calories or weight gain. Instead, he points to a complex chain of biological processes that may affect long-term heart health.
During his career, Dr. Ovadia has witnessed firsthand the consequences of advanced heart disease. In operating rooms, surgeons often encounter blocked arteries and unstable plaque deposits that can interfere with blood flow and increase the risk of serious cardiovascular events.
These experiences have led him to focus not only on treatment but also on prevention.
One of his primary concerns involves insulin resistance and chronic inflammation.
Insulin is a hormone that helps regulate blood sugar levels. When people frequently consume foods that cause rapid increases in blood sugar, the body may be forced to produce larger amounts of insulin. Over time, some individuals can become less responsive to insulin, a condition known as insulin resistance.
Many health experts consider insulin resistance an important factor in the development of several chronic health conditions.
According to Dr. Ovadia, refined carbohydrates may contribute to this process.
Refined carbohydrates are foods that have undergone significant processing, often removing fiber and other naturally occurring nutrients. Because fiber slows digestion, removing it allows these foods to be broken down and absorbed more quickly.
As a result, blood sugar levels may rise rapidly after consumption.
Examples of refined carbohydrate foods commonly found in modern diets include breakfast cereals, white bread products, bagels, rice cakes, crackers, flavored yogurts, certain snack foods, and various packaged convenience products.
Many people are surprised to learn that some foods marketed as healthy options may still contain significant amounts of refined carbohydrates.
For example, certain breakfast products are often promoted as nutritious choices despite containing ingredients that can rapidly affect blood sugar levels.
Similarly, fruit juices, flavored oatmeal packets, and some granola products may appear healthy at first glance but can contain concentrated sugars and highly processed ingredients.
Dr. Ovadia emphasizes that the concern isn’t necessarily about enjoying these foods occasionally.
Rather, he warns about the cumulative effect of regularly consuming large amounts of refined carbohydrates over many years.
Repeated spikes in blood sugar and insulin may contribute to ongoing inflammation within the body.
Inflammation itself is a natural and important biological process. It helps the body respond to injury and infection. However, chronic low-grade inflammation that persists over long periods has been linked to numerous health concerns, including cardiovascular disease.
Researchers continue to investigate the relationship between inflammation and plaque formation within arteries.
Plaque is a buildup of substances such as cholesterol, fats, calcium, and cellular waste products that can accumulate on artery walls. Over time, plaque may narrow blood vessels and reduce blood flow.
In some cases, unstable plaque can rupture, leading to the formation of blood clots that may trigger heart attacks or strokes.
This is why many cardiovascular specialists focus on reducing factors that may contribute to inflammation and plaque development.
Dr. Ovadia’s message resonates with a growing number of healthcare professionals who advocate for dietary patterns centered around whole, minimally processed foods.
Rather than focusing exclusively on calorie counting, these experts encourage people to consider food quality and nutritional value.
One dietary approach frequently recommended by heart health specialists is the Mediterranean-style diet.
This eating pattern emphasizes vegetables, fruits, legumes, nuts, seeds, fish, olive oil, and high-quality protein sources.
