Sugar and caffeine. Two things you likely have more than your fair share of on a regular basis. You've no doubt heard that avoiding sugary and caffeinated beverages is good for you, but do you know why? Caffeine and sugar can both affect your body in negative ways, especially if consumed in excess on a regular basis. The negative aspects of sugar are fairly well known, but caffeine tends to be more of a mystery.

What is Caffeine?

Caffeine is a naturally occurring substance, but it's also one of the most widely consumed drugs in the world. Approximately 90 percent of the world's population consumes caffeine in one form or another. The most widely used form of caffeine is beverages like coffee and sodas. Caffeine is mildly addictive and does have side effects, but it has not been linked to the development of serious medical problems at this time.

How Caffeine Affects Your Body

Caffeine acts as both a stimulant and a diuretic. Caffeine stimulates the central nervous system, which is why you feel more alert after consuming it. Caffeine promotes water loss through urination, which could lead to dehydration if you do not replace the water lost. It is recommended that you drink one glass of water for every cup of caffeinated beverage you consume to help counteract the diuretic effect.

Side Effects

Caffeinated sodas can cause you to have trouble sleeping, especially if you drink them close to bedtime. In addition to sleep disturbances, you may experience a faster than normal heart rate and feel anxious or jittery, and if you are stressed caffeine could intensify those feelings. These side effects are most often noticed if you drink more than you are used to, or are not used to consuming caffeine at all and are generally most intense within an hour of drinking a soda or cup of coffee.

Precautions

Consuming caffeinated and sugary sodas can hike up your calorie intake for the day with just a few sips, and more so if you consume multiple sodas in a day. Limiting consumption is best, especially if you are watching what you eat. Pregnant women, or women hoping to become pregnant and individuals who should not have an increased heart rate should pay special attention to the number of caffeinated sodas they consume.
