Avoiding all processed foods still won’t stop you getting more than you bargained for, as even the most natural products in your shopping basket may have the odd unwelcome addition. The US Food and Drug Administration allows for five rodent hairs in every 18oz jar of peanut butter, while frozen berries can contain up to four larvae or 10 whole insects per 500g. We recommend you don’t look too hard and just think about all that lovely extra protein you’re getting.
