Certain lifestyle habits, such as diet and exercise, can influence cholesterol levels significantly. Consuming a diet high in trans fats and saturated fats can elevate low-density lipoprotein (LDL) cholesterol, increasing the risk of heart disease. On the other hand, regular exercise and a diet rich in fruits, vegetables, and whole grains can help increase high-density lipoprotein (HDL) cholesterol and lower LDL cholesterol. Emphasizing a balanced lifestyle is key to managing cholesterol effectively.
