Soda And Depression: Can Drinking Too Much Soda Cause or Contribute to Depression?


Soda is one of the most widely consumed beverages in the world, with an estimated 185 million liters of soda consumed every day in America alone. While it is no surprise that soda is not exactly beneficial to our health, recent studies suggest that drinking soda may also contribute to depression.

What is Depression?

Depression is a mental disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest in life. Depression can affect anyone at any age, but it is more common in females and teenagers. Depression is a complex illness that can be caused by a variety of factors, including genetics, stressful life events, and medical conditions.

What is Soda?

Soda is a carbonated beverage that is flavored with various syrups, such as cola, lemon-lime, and fruit flavors. Soda is known for its high sugar content, which is a contributor to the obesity epidemic plaguing the United States and other developed countries.

The Link Between Soda and Depression

Several studies have linked soda consumption to depression. In one study entitled “Soda intake and the chance of depression in Korean adults”, published in the Asia Pacific Journal of Clinical Nutrition, researchers found that people who drink more than four cans of soda a day are 30 percent more likely to be depressed than those who drink no soda at all.

Another study, published in the American Journal of Public Health, surveyed more than 260,000 American adults and found that those who drink four or more cans of soda a day are at a significantly increased risk of developing depression than those who do not drink soda.

Why Does Soda Contribute to Depression?

Experts believe that the high sugar content and caffeine in soda may play a role in the development of depression. Sugar causes a rapid spike in glucose levels, followed by a crash, which can leave you feeling sluggish and irritable. Caffeine, on the other hand, can disturb your sleep patterns and make you feel anxious or jittery.

In addition, soda is often associated with an unhealthy diet, which can lead to nutrient deficiencies that may contribute to depression. Research shows that people with depression are often deficient in nutrients such as omega-3 fatty acids, folate, and zinc, which are important for healthy brain function.

How to Reduce Your Soda Intake?

If you are concerned about the link between soda consumption and depression, there are several steps you can take to reduce your soda intake:

  1. Switch to Water: Water is always the best choice when it comes to staying hydrated. Try infusing your water with fruits, vegetables, or herbs to add flavor.
  2. Choose Unsweetened Tea: Unsweetened tea is a great alternative to soda, and it can provide a caffeine boost without the sugar rush.
  3. Opt for Low-Sugar Drinks: If you do choose to drink a beverage with added sugar, look for low-sugar options, such as fruit juice or coconut water.
  4. Set a Soda Limit: If you find it hard to give up soda altogether, set a limit for yourself. Start by reducing your intake to one or two cans a day, and gradually decrease from there.
  5. Read Labels: When you do choose to drink soda, make sure to read the labels carefully. Look for drinks with lower sugar and calorie content.


While the link between soda consumption and depression is still being studied, there is evidence to suggest that drinking soda may contribute to depression. If you struggle with depression or are concerned about your soda consumption, talk to your doctor or a mental health professional for help. Reducing your soda intake can be a great step toward better overall health and well-being.
