Eat beets. If they turn your urine pink/red, then you have low stomach acid. Stomach acid is a very important first step in digestion. Without enough, you can't absorb B12, and you have trouble absorbing zinc as well as several other nutrients.
How many drinks are in a bottle of wine? A typical 25-ounce (750 ml) bottle of table wine holds about 5 standard drinks, each containing about 5 ounces. This serving size of wine contains about the same amount of alcohol as a 12-ounce regular beer or 1.5 ounces of 80-proof spirits. Get to know what 5 ounces looks like by measuring it out at home.
The usual rule of thumb is that 5 ounces of wine is 1 drink. Most wine bottles are 750 ml (25 oz), or about 5 drinks. Even if you have wine with lower than normal alcohol, that's well in excess of the healthy amount. Like Dr. Drake, I don't know how well this correlates to specific side effects like liver damage.
