Answer:

Liver enzymes, including ALT, AST, and GGT, are released by liver cells to facilitate metabolic processes and detoxification. Normally, these levels remain stable. When the liver is damaged due to inflammation, fatty liver disease, medication, alcohol, or toxins, these enzymes leak into the bloodstream, causing elevated levels. This signals liver overload or underlying damage.

Grilled meat, a popular dish, is not beneficial for the liver. Grilling at high temperatures forms harmful substances like heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which can cause liver inflammation and raise enzyme levels with frequent consumption. Grilled meat is often marinated with excessive sugar, salt, and spices, and the charred fat adds to the liver's metabolic burden.

You don't need to avoid grilled meat completely, but limit your intake. Consume it 1-2 times per month, keeping portions under 100g. Choose lean meats, remove the skin, reduce marinade, and opt for air frying or oven baking instead of grilling directly over charcoal. After your meal, consume green vegetables and low-sugar fruits to increase fiber and antioxidants, supporting liver detoxification.

Besides limiting grilled foods, prioritize liver-supporting foods like antioxidant-rich vegetables (kale, spinach, carrots, beets, broccoli) and low-sugar fruits (grapefruit, oranges, apples, guava) to cleanse the liver and boost immunity. Choose healthy protein sources such as fish, tofu, skinless poultry, boiled eggs, and consume whole grains, oats, and brown rice for fiber and B vitamins to aid metabolism. Herbs like turmeric, garlic, and green tea offer natural anti-inflammatory benefits, contributing to liver cell protection.

Individuals with elevated liver enzymes should have regular check-ups with gastroenterologists and nutritionists to monitor liver function and develop a suitable diet. Supplementing with natural extracts like s. marianum and wasabia can help control kupffer cell activity (resident macrophages in the liver), improve detoxification, lower liver enzymes, and support liver recovery from inflammation and fatty liver disease.
