What Are Soft Drinks? A Quick Overview

Soft drinks, often called sugar-sweetened beverages (SSBs), include any beverage with added sugars or artificial sweeteners. Common examples are:

  • Regular sodas (e.g., Coca-Cola, Pepsi)
  • Fruit drinks (e.g., Capri Sun, Hawaiian Punch)
  • Sports drinks (e.g., Gatorade, Powerade)
  • Energy drinks (e.g., Red Bull, Monster)
  • Sweetened teas and coffees (e.g., AriZona Iced Tea)
  • Diet or zero-sugar sodas (using artificial sweeteners like aspartame or sucralose)

A typical 12-ounce (355 ml) can of soda contains 29.4–42 grams of sugar—equivalent to 7–10 teaspoons—often in the form of high-fructose corn syrup or sucrose. These drinks provide “empty calories,” offering no nutritional value like vitamins, minerals, or fiber. Even diet sodas, marketed as healthier, come with their own risks due to artificial additives.

The Health Risks of Soft Drinks: What Science Says in 2025

Regular soft drink consumption is linked to a host of health issues, backed by robust research from 2022–2025. Here’s a detailed look at the risks:

1. Obesity and Weight Gain

Soft drinks are a leading driver of obesity worldwide. Their high sugar content delivers calories without satiety, meaning you’re likely to consume more food overall. A 2022 meta-analysis of 85 studies confirmed that higher SSB intake is strongly associated with weight gain in both children and adults. Reducing SSB consumption, on the other hand, leads to weight loss.

  • Fact: Each daily serving of SSBs increases childhood obesity risk by 60%.
  • Why It Happens: Liquid calories don’t trigger the same fullness signals as solid food, leading to overeating.
  • Diet Soda Trap: Artificially sweetened beverages may increase cravings for high-calorie foods, contributing to weight gain.

2. Type 2 Diabetes

Drinking just one can of soda daily raises the risk of type 2 diabetes by 1.1–26%. A study of 91,249 women found that those consuming one or more SSBs daily had double the risk compared to those drinking less than one monthly. Diet sodas don’t fare much better, as artificial sweeteners may disrupt insulin sensitivity.

  • 2025 Update: A January 2025 study linked SSBs to 340,000 annual deaths, many from type 2 diabetes, highlighting their global impact.

3. Cardiovascular Disease

SSBs increase heart disease risk by 10–20% per daily serving, driven by elevated blood sugar, triglycerides, and LDL cholesterol. Diet sodas are also linked to higher risks of heart attack and stroke, particularly in women. A 2022 review in Nature Reviews Endocrinology confirmed SSBs’ role in cardiometabolic diseases.

  • Mechanism: Excess fructose from SSBs burdens the liver, raising lipid levels and inflammation.

4. Dental Health

The sugar and acidity (from phosphoric and carbonic acids) in soft drinks erode tooth enamel, causing cavities and dental erosion. Each sip triggers a 20-minute acid attack on teeth. Even sugar-free sodas harm teeth due to their acidity.

  • Stat: Soft drinks contribute to tooth decay, the most common childhood disease.

5. Bone Health

Phosphoric acid in soft drinks can leach calcium from bones, increasing the risk of osteoporosis and fractures, especially in women. Studies show reduced bone density in frequent soda drinkers.

6. Kidney and Liver Issues

High phosphoric acid intake is linked to kidney stones and impaired kidney function. Excessive fructose from SSBs also contributes to non-alcoholic fatty liver disease by overwhelming the liver.

7. Cancer Risk

Regular SSB consumption (≥2 per week) nearly doubles the risk of pancreatic cancer and increases endometrial cancer risk in postmenopausal women. Some studies suggest artificial sweeteners may be linked to cancers like non-Hodgkin’s lymphoma, though evidence is mixed.

8. Increased Mortality

A 2022 meta-analysis of 1.2 million people found that daily soft drink consumption raises all-cause mortality by 12% and heart disease mortality by 20%, even for diet sodas. A 2019 study reported a 17% higher risk of early death for those drinking two 250ml glasses daily.

9. Other Concerns

  • Addiction-Like Behavior: High sugar content triggers dopamine release, mimicking addictive substances.
  • Reproductive Health: SSBs may cause earlier menstruation in girls and reduce fertility.
  • Mental Health: Diet soda consumption is linked to mental health issues and delayed child neurodevelopment.
  • Gout: Fructose increases uric acid, raising gout risk by 75% in women drinking one can daily.

Sugar Taxes: A Global Response to the Soft Drink Crisis

Governments worldwide are addressing soft drink consumption through sugar taxes, which increase prices to reduce demand and encourage reformulation. As of 2025, over 50 countries have implemented SSB taxes, with notable success.

Key Examples and Impacts

United Kingdom (Soft Drinks Industry Levy, 2018):

  • Reduced sugar content in soft drinks by 43.7% from 2015 to 2019.
  • Cut daily sugar intake by 3–5 grams per person.
  • Predicted to prevent 64,000 obesity cases and 3,600 dental caries in children over 10 years.
  • Greatest benefits in low-income areas, reducing health inequalities.

Mexico (2014):

  • A 1 peso per liter tax led to a 37% reduction in SSB purchases by 2016.
  • Prevented 239,900 obesity cases, 39% in children, over 10 years.
  • Highly cost-effective, saving $4 per $1 spent on implementation.

South Africa (Health Promotion Levy, 2018):

  • A 10% tax reduced carbonated drink purchases by 29% and sugar intake by 51%.
  • Significant impact in lower socioeconomic groups.

United States:

  • Cities like Philadelphia, Seattle, and San Francisco implemented taxes (2017–2018), reducing SSB purchases by 33% over two years.
  • Philadelphia’s tax cut dental caries by 20% in Medicaid patients.

2025 Updates

  • University of Reading Report: Advocates extending the UK’s sugar tax to all processed foods, citing a 44% sugar reduction in soft drinks.
  • Australia: The Australian Medical Association predicts a 12–18% sugar reduction with a 20% SSB tax, raising $749–814 million annually.
  • WHO Push: The World Health Organization urges global SSB tax increases, estimating $1.4 trillion in revenue over 50 years from a 50% price hike.

Challenges

  • Industry Opposition: Beverage companies, like Coca-Cola, fund studies to downplay SSB risks and lobby against taxes.
  • Cross-Border Shopping: Some consumers buy SSBs in untaxed areas, though studies show minimal impact.
  • Regressive Concerns: Taxes may burden low-income households, but health benefits often outweigh costs.

Diet Sodas: Are They Really a Safe Alternative?

Diet and zero-sugar sodas are marketed as healthier, but they come with risks:

  • Artificial Sweeteners: Aspartame, sucralose, and saccharin may disrupt metabolism, increase appetite, and raise diabetes and heart disease risks.
  • No Weight Loss Benefit: Studies show diet sodas don’t aid weight loss and may promote weight gain.
  • Other Risks: Linked to mental health issues, neurodevelopmental delays in children, and potential cancer risks.

Verdict: Diet sodas are not a safe substitute. Opt for unsweetened alternatives instead.

Healthier Alternatives to Soft Drinks

Cutting back on soft drinks doesn’t mean sacrificing flavor. Try these healthier options:

  1. Water: Tap or sparkling water is the best choice for hydration. Add lemon, cucumber, or mint for flavor.
  2. Unsweetened Teas: Herbal or green teas offer antioxidants without sugar.
  3. Black Coffee: Provides a caffeine boost without added calories (in moderation).
  4. 100% Fruit Juice (Limited): Contains natural sugars but offers nutrients; stick to small portions.
  5. Homemade Drinks: Make your own low-sugar beverages, like this Very Berry Summer Quencher:
    • Ingredients: 1 cup mixed berries, 2 cups sparkling water, 1 tsp honey (optional), ice.
    • Instructions: Blend berries, mix with sparkling water, add honey if desired, and serve over ice.

The CDC recommends sparkling water as a low-risk, tooth-friendly option.
