A diet high in unhealthy fats, refined sugars, and excessive calories is one of the primary contributors to fatty liver disease. Overconsumption of sugary beverages, processed foods, and fast food can lead to the deposition of fat in the liver. Excessive fructose consumption, often found in high-fructose corn syrup and sugary snacks, is especially concerning, as the liver metabolizes fructose into fat. A diet rich in fruits, vegetables, lean proteins, and whole grains is essential to maintain a healthy liver.
