But it’s just one drink a day. How bad could it be? I read where red wine is supposed to be good for you. . . . .
I will answer this question on 2 levels.

First the physical.

If you have one glass of wine every day for an entire year, you are adding 54750 calories to your diet. This totals to about 15 pounds of extra calories.  That is just one glass of wine. Add a couple more for the weekend and you can begin to see the problem we are headed toward.What is more alarming is that alcohol, despite the volume of studies attempting to state otherwise, does NOT have any nutritional value. It does not provide vitamins, minerals, proteins, etc. But it does provide calories, in the form of excess carbohydrates and sugar, 2 issues that are proving to be highly problematic world-wide. (Excess sugar/carb consumption is the #1 reason for obesity. Lack of exercise is #2. The rest of the factors are a distant third.)

Alcohol also has a tendency to cause bloating in middle and lower sections of the gut. When you drink, your body needs more water to process the alcohol in your bloodstream. If you're not drinking water, your body retains water in order to use it for this process. Of course, if you're drinking a lot, you might retain more water, causing a large belly appearance.

Is red wine "healthy" for you? There are some health benefits but you can also get those health same benefits from eating healthy without the laundry list of problems. 

The second matter is an emotional one. Celebrating successes is a great thing to do. In fact, I would say to lead a healthy life with passion, it is a must. For some, this includes alcohol consumption which when done in moderation is perfectly fine. The problem is when every day is characterized by "celebration foods and drinks" (ex/ From cookies to wine and every stop in between), what should be UNcommon becomes too common. Thus a celebration becomes the less-than-special event it was designed to. The whole point is missed.
There are a finite number of extra special days in our lives -- birthdays, wedding, graduations, various achievements etc. Treat them as such.

Your body is the sensitive vehicle that allows you to get to those days, to achieve those special moments. Treat it as such.
