breadserving

Breadserving is a unit of portion used in nutrition, meal planning, and food service to quantify bread intake. It provides a standard reference for estimating calories, carbohydrate content, and other nutrients derived from bread.

In many dietary systems, a bread serving is defined as one slice of bread. In U.S. dietary guidelines, one slice of bread is typically considered one ounce-equivalent of grains, about 28 grams, though actual weight varies with loaf type and slice thickness.

The weight per slice can vary significantly. Common white sandwich slices are around 25–30 grams; thick-sliced or artisanal loaves may yield 40–60 grams per slice. Rolls or baguette portions may count as a single serving if they are similar in size to a typical slice, or as multiple servings if larger.

In practice, breadserving is used to portion bakery products, label nutrition, and assist diners in meeting dietary goals. Menu descriptions may specify “one slice,” “one roll,” or “two slices” to indicate servings, aiding consistency across meals and vendors.

Cultural and dietary variation exists: serving conventions differ by country and cuisine, with some guidelines emphasizing whole-grain or enriched varieties. When planning meals, it is important to consider bread type, portion size, and individual nutritional needs.
