silly food labelling

[ymu]

Wait... I have confused matters here

15% could be high, depending on what else is in the food...

I read that athletes are ok on a calorie ratio of about 65:15:20 carbs:fatrotein (the ratio depends on what activity you're talking about and which nutritionist you talk to)...

So a food might have 15% of its calories as fat, the actual food might not contain 15% fat (because it contains water and insoluble fibre and whatnot - stuff that we cannot get energy from)

So... that's why 15% didn't sound high... see where I was coming from? in reality a food could contain 15% fat, 20% carb, 15% protein, and 50% water, now that would be pretty high in fat.

The 15% fat in ice cream is by weight. It'd be a higher % by calories because fat is very energy dense. Food labelling requires the weight of fat included, not the calorie contribution it makes.

There's no way that the "85% fat free" claims relate to % calories because they'd be able to make the claim sound even better if they based it on the weight.

Unless I'm reading that wrong, they're essentially duplicating an enzyme from a (dead) calf's stomach in modified yeast cultures to form rennet...

You haven't half! I used to be quite clear what the labels meant, now I'm not so sure.

Just to be clear, it's by weight, isn't it?

Natural vegetable rennet is available. It is used in many mediteranian cheeses, often nettle, fig or thistle. I had thought modern industrial vegetarian rennet was a mold, whether GM or otherwise.

Wait, shit, all this time I thought that the 65:15:20 ratio meant you should have 65g of carbs, 15g of fat and 20g of protein! oh dear. How silly.

I dont count calories so it doesnt really matter - but it basically was an easy way of saying 'eat mostly carbs, and the rest should be almost equal amounts of fat and protein'

AFAIK the production of artificial rennet does not require material from real live calves. It is a grey area in that VS leaflet though because it is a GM product - according to wiki, calf-genes are used to modify bacteria, fungi or yeast to make them produce chymosin.

I didn't know that. I wonder why, though? Because as I understood it there were natural molds which caused coagulation.

There are. Commercial vegetarian cheese tends to use chymosin. Mass production innit.
