Food portions refer to the specific amounts of food served or consumed in a meal. They can vary based on dietary guidelines, cultural practices, and individual preferences. Understanding food portions helps people manage their intake of calories and nutrients, promoting a balanced diet. Proper food portions can be measured using standard units like cups, ounces, or grams. Tools such as measuring cups and food scales can assist in determining the right portion sizes. Additionally, visual cues, like comparing a portion to the size of a baseball or deck of cards, can help individuals estimate appropriate serving sizes without precise measurements.
