Eating such foods in combination with protein in meals will benefit.
• Deficiencies in B-complex vitamins such as thiamine, folate or folic acid, and B12 are common with alcoholism, and inadequate stores of other B vitamins and vitamin C frequently occur. A patient should take supplements and vitamins on consulting a doctor.
• Malnutrition is common during alcohol consumption and is revealed slowly and gradually. The patient becomes tired and develops a weaker immune system—which means they are more susceptible to infections. These problems need to be identified and treated during the recovery process—ideally by a team of healthcare professionals.
• The patient should change his drinking priorities and prefer drinks like apple cider, vanilla shake, mixing juice or lemonade with sparkling water etc.

Chronic alcoholism: Alcoholism is the addictive drinking of alcohol that results in physical & mental problems. A person can become an alcoholic out of stress, depression or just after developing a chronic habit. Excessive alcohol use can damage various organs like the brain, heart, kidneys and most importantly, the liver, which leads to liver cirrhosis (liver dysfunction). In most severe cases, there is an immediate need for liver transplantation. During pregnancy, drinking alcohol in large amounts affects the unborn baby and may lead to various birth complications.
