How Does Soda Really Affect Your Brain?

Soda is one of the most consumed beverages second to water, yet its effects on the brain cannot be ignored. Certain ingredients in soda such as caffeine and artificial sweeteners have known side effects that hinder normal Coca colabrain activities. According to a recent discovery by scientists, people who drink sugary beverages daily are more likely to have smaller overall brain volume, smaller hippocampus, and poor memory. Further studies revealed that people who drank diet soda frequently were more likely to develop stroke and dementia when compared to those who didn’t.

Below is a look at some of the negative side effects that soda can have on the brain.

8 Ways Soda Affects Your Brain

 Alzheimer’s Disease

This is a type of irreversible brain disorder characterized by loss of memory, cognitive function, and inability to carry out normal tasks when at a pronounced stage. Although the disease is more common among people in their mid-60s, changes in the brain due to lifestyle factors including consumption of sugary beverages can trigger Alzheimer’s development at an early age.


Despite the brand, sodas are composed of a significant amount of caffeine; a chemical compound that increases mental alertness in the brain. The caffeine inhibits the activity level of certain brain chemicals (adenosines) which naturally exist to increase fatigue, decrease arousal, and when in excess, it promotes the development of a type of brain chemical that increases feelings of pleasure. In the absence of active adenosines, your level of alertness increases, making you restless and sleepless even at night. Further, sleeplessness may trigger other brain responses, including high blood pressure and increased heart rate.

Memory Loss

The sweeteners are a major hindrance to the production of Brain-Derived Neurotrophic Factor (BDNF), a naturally occurring brain chemical responsible for the formation of new memories in the brain. Inadequate BDFN may cause severe memory loss characterized by an inability to learn or remember anything. Indeed, a study by researchers from Boston University School of Medicine associates impaired memory with consumption of sugary beverages such as soda.

Intense Food Cravings

The brain controls food cravings by naturally creating a balance between the food taken into the body and the exact amount required. Through this natural process, food satisfaction is created and the risk of developing obesity kept away. Excessive soda consumption can, however, reduce your brain’s ability to gauge how much energy your body requires from sugar. As a result, this will lead to intense food cravings, causing you to eat more.

Irritability Or Violence

When you have a diet filled with frequent carbonated drinks, you are more likely to react violently. This occurs because excess sugar found in soda influences mood and behavior causing aggression.

Wrong Judgment

Sucralose and Saccharin present in the artificial sweeteners can affect the way an individual thinks. They promote indecision and inability to make the right choices even in life. Frequent consumers of soda, for instance, will most likely settle for short-term choices over longer-term choices in life.

Brain DamagePink Brain

The high amount of sugars resists proper blood flow into the brain, causing heart-related complications. If left untreated, such complications could develop into a stroke, paralysis, and even permanent brain damage.


One of the major causes of depression results from changes in the functioning of the brain’s neurotransmitters. Soda intake alters the brain’s naturally occurring chemicals, putting you at a higher risk of developing depression.

Alternatives To Consider

Limiting the amount of soda consumption can help improve brain health and prevent Alzheimer’s disease. You may opt for an occasional treat, but its high sugar and calorie content makes it harmful if taken regularly. Fortunately, healthier options such as low-sugar fruit juice and Green tea can be used as ideal substitutes. This still guarantees you a refreshment similar to soda, but with fewer health risks if any.
