Nothing wrong with the 'real' natural foodstuffs, such as butter, full fat milk or the like - it's just the quantities that some people consume it in, as well as a total lack of exercise, that means people don't burn it off like they used to and so attempts are made to replace it with stuff that has the nourishment value of sawdust - eat as much as you like it won't do any harm. Or good, either.
In any case, no matter how healthy we all are - or not - we still die anyway. Depressing, ain't it?
