Lesson 3 What Is Soda Doing to You?
Acid
Most soda contains several types of acids.
Acid is a chemical substance with a sour taste.
When added to water, it produces a sharp flavor.
Acid also delays the growth of bacteria, which extends the expiration date of a product.
However, acid interferes with the body’s ability to absorb calcium, and as a result, bone softening occurs.
Also, the acid in sodas interacts with stomach acid, slowing digestion and blocking nutrient absorption.
Furthermore, it can damage tooth enamel, the hard substance that protects your teeth.
If you drink sodas regularly, your teeth decay more easily.
Caffeine
When you hear the word “caffeine,” you most likely think of coffee.
But some sodas, especially colas and carbonated energy drinks, also contain caffeine.
Caffeine makes you feel more awake, but it may bring about an irregular heartbeat.
A single can of cola may not affect you much, but if you consume colas regularly, they can make you feel more nervous and keep you from sleeping well at night.
