Fat and oils, especially those found in sea critters, are essential for our health . They do not contribute to weight gain but are used in organ building and repair . Growing up on a no-fat diet would be dangerous to the brain .
Reminds me of the pressure to give kids only low fat or no fat milk, and a few years latter kids were turning up not healthy. I think they changed it to dont start till about age 5. Developing bodies need fat for a lot of reasons, one of which is that some important nutrients only travel in fat, and growing bodies need a lot of nutrients. 30% cal from fat seems reasonable but then a HS lunch as to max at 850 cal and the moderately active HS boy needs 2600 a day I got a feeling that lunch is going to leave kids hungry in a hour or so.
The limit is 30% cal by fat, which works out to the meal can be about 16% fat. This should be doable, but the science is not there on this question I think. The normal knock on fat is that they pack a lot of calories, but these meals already have calorie limits so that is meaningless. We were told for 30 years that we should limit fat because we need to limit the amount of cholesterol that we eat, which was never backed by science and science has proven that eating cholesterol does not effect our blood cholesterol at all.
We see this all the time where those who get off on telling us what we should eat, sometimes going to great lengths to try to limit our choices lie to us about their case. Over and over again,
Leave the kids the **** alone. There will be plenty of time for them to be nutrition lab rats when they are adults, when they have the ability to consent to the experiments.
