Lasagne

Food · Other · Food, Typed Supps

A balanced enough dish on its own. The frozen version is usually much saltier and has less meat.

Stage by stage

Intake (Layers broken up): Chewing combines pasta, meat sauce and cheese sauce into one mixed bolus.
Stomach (Fat slows emptying): The fat content holds the meal in the stomach longer, flattening the glucose response.
Small intestine (Mixed absorption): Starch, amino acids and fat absorb together; fat carries the cooked tomato carotenoids.
Tissues (Fuel and repair): Glucose refills glycogen while amino acids support muscle repair.

Time to effect

Food vs. supplement

Not applicable — this is a mixed meal rather than a source of any single nutrient. It is worth noting as a whole-food case: the protein, calcium and carotenoids arrive together in a food matrix that no individual supplement reproduces.

Kitchen tip

If sodium is the concern, the homemade route wins mainly through the sauce: a tinned tomato base with no added stock cube or jarred passata is where most of the difference is made, not in the pasta or the cheese.

Common myth

"Frozen lasagne is basically the same as homemade." In reality: On calories it often is. On sodium it usually is not, and the meat-to-sauce ratio tends to be lower, with starch and thickeners taking up the space.
