evidence: In April 2002, versions of the 'Eat fruit on an empty stomach" e-mail were appended with a list of six fruits and their properties, which was excerpted from a much longer e-mail about foods that supposedly cause cancer and "miracle cures" that could be found in supermarkets. In July 2007, the 2006 admonition against drinking cold water immediately after meals because it causes cancer (it doesn't) was added to the piece, as was in November 2007 the 1999 advisory about surviving heart attacks by using cough CPR (in a nutshell, don't try it). [...] In the 1980s, part of the regimen advocated by the Diamonds, authors of Fit for Life, dictated that nothing but fruit and fruit juices be consumed before noon. (They believed the body has three natural cycles regarding its use of food: noon to 8 p.m. for eating and digestion, 8 p.m. to 4 a.m. for absorption and use, and 4 a.m. to noon for elimination of body wastes and food debris. Fruit in the morning — and nothing but fruit at that time — is therefore key to the elimination cycle.) Eat fruit on an empty stomach only, said the Diamonds, otherwise the meal can rot, ferment, and turn to acid because the fruit is being delayed in the stomach and prevented from immediately entering the intestine.
