5 Everyday Habits That Can Gradually Increase Cholesterol and Heart Disease Risk, Experts Say

Protecting your heart takes more than regular exercise. The food and drink choices you make each day can also influence cholesterol levels and your long-term risk of cardiovascular disease. Even habits that seem harmless in small amounts may, over time, contribute to high cholesterol, higher triglycerides, and other heart-related risk factors.

Health experts say a number of common eating mistakes can slowly harm cardiovascular health. Overdoing foods high in unhealthy fats, sugar, or alcohol can upset the balance of fats in the blood and raise the chances of complications later on. The encouraging part is that spotting these habits early and making smarter choices can help support heart health.

1. Eating too many high-fat foods

It can be difficult to pass up greasy breakfast sandwiches, bags of chips, or fried chicken, but nutritionist and certified trainer Mary Sabat says making fatty foods a routine part of the diet is one of the worst things for cholesterol.

“Consuming foods high in saturated and trans fats can lead to elevated cholesterol levels,” she says. She adds that fried foods, processed snacks, fatty cuts of meat, and full-fat dairy can raise LDL, or “bad cholesterol.”

Sabat also warns that restaurant meals can be misleading: “Eating out in restaurants, frequently people don't realize how unhealthy the oils are that are used in most foods. They can easily be fooled into thinking they are eating healthy when in fact the food is full of inflammatory fats which raise cholesterol.” That is why fried appetizers are best avoided.

2. Eating too many sugary foods

Another food group to limit for better cholesterol control is sweets. Too much sugar can create a range of health problems, and Sabat says it can also contribute to higher cholesterol.

“While sugar itself may not directly cause high cholesterol, it can contribute to elevated triglyceride levels, which are associated with an increased risk of heart disease,” she warns. “High sugar intake is often linked to a diet that is low in essential nutrients and high in calories, leading to weight gain and an unfavorable lipid profile.”

3. Drinking too much alcohol

Having a cocktail or beer from time to time is one thing, but heavy alcohol use can be a serious health risk. Beyond speeding up visible signs of aging, it may also increase the likelihood of heart disease.

“Heavy drinking can lead to high blood pressure, irregular heartbeats, and increased levels of triglycerides (a type of fat in the blood),” Sabat says. “As people age, their bodies may become less efficient at processing alcohol, making excessive consumption even more harmful to the heart and cardiovascular system.”

4. Eating too much red and processed meat

A juicy burger, a beef-filled burrito, salami, or beef jerky may be popular choices, but eating too much red meat and processed meat can clog arteries and increase heart disease risk over time.

“Consumption of both red meat and processed meats has shown a consistent relationship across multiple studies with increased risks of heart disease, cancer and diabetes—with the extent of increased risk varying with the amount of red meat eaten,” Dr. Nick West, a cardiologist and Chief Medical Officer & DVP of Global Medical Affairs of Abbott’s vascular business, says.

5. Not getting enough fiber

If meals are centered on processed foods, red meat, and sugary snacks instead of fruits, vegetables, whole grains, and legumes, the diet may be missing a key heart-healthy nutrient: fiber.

Soluble fiber can help lower LDL cholesterol by reducing the amount of cholesterol absorbed into the bloodstream. When fiber-rich foods are lacking, there may be fewer opportunities to support healthier cholesterol levels and lower cardiovascular risk over time.

To raise your intake, try adding oats, beans, lentils, apples, pears, and vegetables to your meals. Swapping refined grains for whole grains and including more plant-based foods can also support healthy cholesterol levels.

While no single food change can eliminate heart disease risk, getting enough fiber as part of a balanced diet is a practical step toward better long-term cardiovascular health.
