This one particularly galls me because for years when I was dirt poor and had very few food choices, I thought I was doing a healthy thing by buying "fresh" orange juice from Tropicana.
Alissa Hamiliton has written a new book on the subject called "Squeezed: What You Don't Know About Orange Juice."
Some reality checks:
1. There is more vitamin c in a single orange than in a full glass of industrial orange juice
2. Truly fresh orange juice only last a few days. It if last for weeks (or months), it's an industrial product.
3. Until the Florida orange growers launched a campaign in the early 20th century to deal with their surplus crop, the only people who drank orange juice were Floridians who had a tree in their backyard. There is nothing particularly healthy or natural about drinking orange juice - and the industrial product is a total waste of money.
