You said you take alcohol daily and your LFT showed mild increase in Bilirubin
levels and liver enzyme levels. It indicates that your liver had some injury due to your alcohol intake. The serum bilirubin levels and liver enzymes levels will revert back to normal in few days. But taking alcohol in future may again cause elevation of bilirubin and liver enzymes.
Daily alcohol intake may cause Cirrhosis
of liver with Portal Hypertension
due to which you will have permanent liver failure
and its dangerous to life.
About the food, yeah you can take spicy food if you don't have any Gastritis
problem. But if you develop Cirrhosis and portal hypertension, you need to take low salt and less spicy food.
My advice is to stop taking alcohol and be on follow up with your physician.
