Another NANNY STATE FAIL, retreat on "healthy" School Lunches

Furthermore, skimmed and semi-skimmed cows’ milk is also less nutritious than whole milk. That’s because the cream contains the fat-soluble vitamins A, D, E and K - important, among other things, for strengthening immunity to infections, neutralising the effects of damaging free radicals and keeping bones healthy.

It's becoming widely accepted that fats actually curb your appetite, by triggering the release of the hormone cholecystokinin, which causes fullness. Fats also slow the release of sugar into your bloodstream, reducing the amount that can be stored as fat. In other words, the more fat in your milk, the less fat around your waist. Not only will low-fat milk fail to trim your gut, it might even make you fatter than if you were to drink whole, according to one large study. In 2005, researchers from the Harvard School of Public Health and other institutions studied the weight and milk consumption of 12,829 kids ages 9 to 14 from across the country. "Contrary to our hypothesis," they reported, "skim and 1% milk were associated with weight gain, but dairy fat was not."

To turn skim milk white, "some companies fortify their product with powdered skim," says Bob Roberts, a dairy scientist at Penn State. Powdered skim (which is also added to organic low-fat milks) is produced by spraying the liquid under heat and high pressure, a process that oxidizes the cholesterol. In animal studies, oxidized cholesterol triggers a host of biological changes, leading to plaque formation in the arteries and heart disease, Spanish researchers reported in 1996. "OCs are mutagenic and carcinogenic," they wrote. In 1998, Australian researchers studied rabbits fed OC and found that the animals "had a 64% increase in total aortic cholesterol" despite having less cholesterol in their blood than rabbits fed natural sources of the substance. (A 2008 Chinese study with hamsters confirmed these findings.) Roberts says the amount of OC created by adding powdered skim is "not very much," but until the effects on humans are known, it's impossible to say what's a safe level.
