Final answer:
The Dietary Guidelines for Americans don't specify an exact number of 1 oz servings of meat for school lunches. Instead, they recommend that students have protein as part of their balanced meal, as illustrated by the MyPlate model, which typically reflected into school lunch offerings.
Step-by-step explanation:
The Dietary Guidelines for Americans recommend specific servings for different food groups, including the meat group. However, the guidelines do not prescribe an exact number of 1 oz servings of meat for school lunches. Instead, they provide general recommendations for daily protein intake for different age groups. For school-aged children, it is suggested that they include protein foods in their meals, which can come from meat, fish, poultry, eggs, soy products, nuts, and seeds.
According to the MyPlate model, which is part of the Dietary Guidelines, half of a student's plate at lunch should consist of fruits and vegetables, and the other half should be grains and protein foods. The MyPlate model encourages a balanced meal with protein being a part of it, but it does not specify servings in ounces. Schools typically provide lunches that align with these guidelines to ensure that children receive balanced nutrition.
