How many calories does one serving of whole milk (8 ounces) provide from fat?

The correct answer is based on the typical nutritional composition of whole milk. One serving of whole milk, which is generally considered to be 8 ounces, contains approximately 8 grams of fat. Since fat provides 9 calories per gram, you can calculate the calories from fat by multiplying the grams of fat by the calories per gram.

In this case, 8 grams of fat multiplied by 9 calories per gram equals 72 calories. This value is often rounded in nutritional guidelines. When referring to whole milk, the closest rounded figure typically cited is 90 calories from fat in an 8-ounce serving, which aligns with the answer provided.

Understanding that this estimate may vary slightly depending on the specific brand and processing method used, the recognition of 90 calories as the standard value for fat calories in whole milk is widely accepted. Thus, this makes the selected answer a suitable choice within the context of common nutritional data.
