The peels from
fruits such as lemons, limes and oranges contain a very high amount of
flavorful oils that, when used in small amounts, go a long way to add hints of
citrus to a dish or baked good.
Here are a few other commonly reported irritants in diets: excessive caffeine (including chocolate);
flavorful spices such as garlic, curry, cumin, and cinnamon (interestingly enough, women in countries where spicy foods are a staple don't seem to report these problems on average); highly acidic foods like tomatoes,
citrus fruits and their juices; gas producing vegetables like onions, broccoli, cauliflower, brussel sprouts, cabbage, bell peppers, and cucumbers; and very spicy foods.
