"Yes, it is an interesting article but I find general tone of total acceptance of traditional gender roles utterly depressing."
Yes, just part of the unusal conspiracy to keep women down.
In fact I find it quite hard to believe. Families where both parents work tend to have more money. The more money a family has in the UK the less likely the children are obese - compare Scotland (fried mars bars) with Ken and Chelsea (slimmest borough in England).
On the question of quoting I suspect most quotes taken are too short to amount to a separate copyright work and therefore it doesn't breach your rights to have them reproduced. If you write a lot (as I sometimes do) though that might be different. If the quote from the terms above is right they really ought to change that wording to allow journalists to use the material too so it's clear.
