Chicken oil is commonly known asbutter,containing a small amount of protein,and is relatively more nutritious.Its calorie content is lower thanlard.However, the following situations should reduce consumption of chicken oil: patients with biliary tract diseases who frequently suffer from gallstones and cholecystitis, as excessive chicken fat digestion requires participation of bile, which may stimulate gallbladder contraction and exacerbate cholecystitis attacks.People with excess stomach acid should not eat too much,as chicken oil has the effect of stimulating gastric acid secretion.Patients with peptic ulcers, excess stomach acid, or gastrointestinal bleeding are generally advised to avoid eating it in large quantities.Those with kidney dysfunction should also limit their intake,as chicken oil contains some small-molecular proteins.For patients with acute nephritis, chronic renal insufficiency, or uremia,due to the liver and kidneys' inability to promptly process protein breakdown products, excessive consumption of chicken oil can lead to hyperammonemia and worsen their condition.Chicken oil and lard both belong to saturated fatty acids, so it is better to minimize intake.Personal recommendation: prefer vegetable oils (such as soybean oil or rapeseed oil are good choices).
