How many grams per serving must a food contain to be classified as "low fat"?

To classify a food as "low fat," it must contain 3 grams or less of fat per serving. This guideline is established by regulatory agencies that define food labeling terms for consumer clarity and health considerations. Foods labeled as low fat are typically those that help consumers make healthier dietary choices by reducing overall fat intake, which can contribute to weight management and lower the risk of certain health issues.

The standard for "low fat" is part of broader nutritional labeling regulations and helps consumers make informed decisions while shopping. Understanding this classification is essential for anyone involved in nutritional analysis or weight management, as it directly impacts dietary recommendations and labeling practices.

In the context of the other choices, the values presented do not meet the criterion set for "low fat." Therefore, the correct classification of low fat being 3 grams is based on established nutritional standards that aim to provide transparency and promote healthier eating habits.
