I'm just reading some of Vanita Gaglani's book.
In the section under food & drink to avoid, she lists:

flavoured milk
carbonated drinks
tea
coffee
chocolate
citrus fruits
juices
dairy products
ketchup
mayonnaise
butter
grains
cheese
most breads
tomatoes
ice cream
cookies
potato chips
canned soup

That's my whole diet.
Kill me now.
