Q: Are there any vitamins or minerals in a glass of wine?—Ben
A: Yes. If you're curious about specifics, you can find the complete breakdown of nutrients in an average glass of table wine at the USDA website. Search for "wine, table, red" or "wine, table, white." Some highlights: An average glass of red table wine contains 12 mg of calcium, 18 mg of magnesium and 8.4 mg of choline. That would be 0.1, 4 and 1.5 percent (respectively) of the recommended dietary allowance for men between the ages of 31 to 50.
