A staple in French kitchen, French bread -- sometimes referred to as baguette -- combines flour, yeast, water and salt to make a crusty loaf. While the bread does impart a somewhat nutty, buttery flavor, one slice of French bread does not contribute a great deal of nutritional value to your meal plan.

A 2-ounce piece of French bread contains 164 calories. If enjoying it as a snack, this fits in well with the recommended calorie range for snacks, which is 100 to 200 calories -- enough to beat any hunger pangs and provide energy. When having a piece of French bread with a meal, however, carefully calculate the number of calories in your eating plan to avoid consuming too many calories. One portion of this bread also contains 1 gram of fat.

A 2-ounce serving of French bread contains several vitamins and minerals, giving you more than 10 percent of your recommended intake of the B vitamin folate, thiamin, niacin and riboflavin. B vitamins aid in metabolism in your body and help produce red blood cells, preventing anemia. The USDA reports that the same serving of French bread delivers more than 10 percent of the recommended daily intake of several minerals, including sodium, manganese and iron, but the mineral with the highest concentration is selenium. Selenium helps protect your body from heart disease, thyroid disease, cancer and declining brain function, according to the National Institutes of Health Office of Dietary Supplements. A 2-ounce serving of French bread contains 15.2 micrograms, which is 27 percent of the recommended intake of 55 micrograms.

One serving of French bread serves up 32 grams of carbohydrates, a macronutrient used for energy. Women require 225 grams of carbs per day, while men should consume up to 325 grams. French bread provides 1.4 gram of fiber, a form of carbohydrates that stays solid in your body to provide bulk in your diet. You should consume 25 to 38 grams of fiber per day for optimal health. This serving of bread also contains 6.66 grams of protein.

The sodium content in a piece of French bread may make it a poor choice if you suffer from hypertension. Each serving contains 291 milligrams of sodium, or 13 to 20 percent of the daily value for sodium. Including excess salt in your diet can raise your blood pressure, cause your body to retain water and increase your risk of a stroke or heart attack.

French bread traditionally includes white flour in the recipe, but if you are making this bread at home, consider using whole grain flour to increase the nutritional value. This will, however, change the taste of the bread, giving it a nuttier flavor and a chewier texture. It will also increase the vitamin and mineral content considerably, as well as the fiber.
