Your blood sugar spikes, causing an insulin burst that tricks the
liver into converting all sugars into fat. Within 40 minutes, caffeine
absorption is complete, and the rest of your body responds accordingly:
Your pupils become dilated, your blood pressure rises, and the liver
begins to dump even more sugar into your bloodstream.
That’s only the first hour. Over time, a couple of sodas a day will start to affect nearly all parts of your body. For example:
A study published in the journal Neuroscience found that excessive amounts of added sugar can reduce the production of a chemical known as brain-derived neurotrophic factor (BDNF).
And with inadequate levels of BDNF, everyday cognitive tasks like learning and memory formations become much more difficult.
“Our results indicate that a popularly consumed diet can influence crucial aspects of neuronal and behavioral plasticity associated with the function of BDNF,” the researchers wrote in their conclusion.
Compared to participants who drank the least soda, those who drank the most were 20 percent more likely to have a heart attack.
“Consumption of sugar-sweetened beverages was associated with increased risk of CHD and some adverse changes in lipids, inflammatory factors, and leptin,” the researchers concluded.
"The amount of soft drink consumption is associated with an increased chance of asthma and/or COPD,” Dr. Zumin Shi, a researcher at the University of Adelaide and lead author of the 2012 study, wrote.
“There exists a dose-response relationship, which means the more soft drink one consumes, the higher the chance of having these diseases.”

A diet high in sugar can interfere with a number of neurological processes, particularly those involved in memory making.A study published in the journal Neuroscience found that excessive amounts of added sugar can reduce the production of a chemical known as brain-derived neurotrophic factor (BDNF).

In 2012, a study from Harvard University found that people who drink only one can of soda a day dramatically increase their risk of chronic heart disease (CHD).Compared to participants who drank the least soda, those who drank the most were 20 percent more likely to have a heart attack.
“Consumption of sugar-sweetened beverages was associated with increased risk of CHD and some adverse changes in lipids, inflammatory factors, and leptin,” the researchers concluded.
Your Lungs
Scientists have also linked soda consumption to an elevated risk of pulmonary complications, such as Chronic Obstructive Pulmonary Disorder (COPD)."The amount of soft drink consumption is associated with an increased chance of asthma and/or COPD,” Dr. Zumin Shi, a researcher at the University of Adelaide and lead author of the 2012 study, wrote.
