Re: Niacin for alcohol cravings
It's pretty simple actually, alcohol has know nutritional value, it's empty calories. so if you drink heavily, it's replacing what you would normally be putting in your body that would have a nutritional impact. Experts, aka Dr.s say "To counteract weight loss and protein deficiency, people with drinking problems should eat between 2,000 and 3,000 calories a day," "Most of those calories--about 60 percent--should be in the form of carbohydrates such as breads, pastas and other grains as well as fruits and vegetables."
And that means no junk food.
You can do a simple Google search on How does heavy drinking affect b Vitamins, and you'll get tons of information and specific value charts for what Vitamins you should take approximately how much of each day, etc.
