A hiatal hernia makes it easier for stomach acids to rise to the esophagus, usually called heartburn. To reduce this symptom It's important a diet that consists of
less: citrus, spicy, fried, fatty foods, coffee, tea, chocolate,
carbonated drinks, dairy products and tomato (because it's also acidic).
Some examples of appropriate foods are: apples, bananas, grains, soy milk, water, carrots, potatoes, peas, a low fat yogurt/cheese, (anything with low fat is ideal), etc.
Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.
