Old MacDonald out of a Job?

Old MacDonald had a farm,
Ee I ee I oh.
But then we found red meat caused harm,
O m g oh no.

And on that farm were cows and pigs
That now we know have cancer links
And a higher degree
Of heart disease.

Old MacDonald asked them why,
Ee I ee I oh.
The Harvard scholars then replied
Here, we told you so.

Our study recently has shown
That if you eat red meat you’re prone
To suffer more from heart disease
And be at risk of the big C.

Are farmyard friends really unsafe?
Oh I don’t think so.
Will Old MacDonald close the place?
Here’s what you should know.

That you can have bacon and such
Though maybe just not eat as much
And not have cow for every dish
But substitute for game and fish
That old farm sells chickens too
Ee I ee I oh.
