From the Guidelines

Excessive diet soda consumption is strongly associated with an increased risk of cardiovascular disease (CVD) events, diabetes, and chronic kidney disease (CKD), making it crucial to minimize its intake. The consumption of sugar-sweetened beverages, including diet soda, has adverse effects on lipoproteins, such as LDL-C, apolipoprotein B, and plasma triglycerides 1. Some of the key consequences of excess diet soda consumption include:

  • Increased risk of CVD events, including in patients with chronic coronary disease 1
  • Association with chronic conditions, including diabetes and CKD 1
  • Adverse effects on lipoproteins, including LDL-C, apolipoprotein B, and plasma triglycerides 1
  • Potential disruption of gut bacteria and alteration of glucose metabolism due to artificial sweeteners
  • Erosion of tooth enamel and contribution to dental decay due to high acidity
  • Increased cravings for sweet foods, potentially leading to higher calorie consumption from other sources
  • Possible links to increased risk of heart disease, stroke, and depression, although causation is not definitively established
  • Caffeine-related side effects, such as sleep disturbances, anxiety, and increased heart rate, when consumed in large quantities. Limiting diet soda consumption and opting for water, unsweetened tea, or naturally flavored water as primary beverages is advisable for better health. Minimizing intake of simple carbohydrates and refined grains, including sugar-sweetened beverages like diet soda, supports a healthier cardiometabolic profile 1.

From the Research

Consequences of Excess Diet Soda Consumption

There are no direct research papers provided to assist in answering this question. However, some studies suggest that diet soda consumption may be associated with various health problems, but the provided evidence does not directly link excess diet soda consumption to specific consequences.

Related Health Issues

  • Metabolic disorders, such as lifestyle-related diseases, are known risk factors for dementia 2
  • Oral diseases, including periodontal disease and tooth decay, are associated with systemic metabolic disorders and may be indicators of risk factors for developing dementia 2
  • Metabolic bone diseases can affect tooth eruption, resulting in premature, delayed, or failed tooth eruption 3
  • Missing teeth have been linked to incident cardiovascular disease, diabetes, and all-cause mortality 4
  • Dental caries have been associated with metabolic diseases, such as cardiovascular injury and hyperglycemia 5

Potential Health Risks

  • Systemic inflammation and risk factors for cardiometabolic diseases may be associated with missing teeth 4
  • Headaches can be secondary to disorders of homeostasis, including metabolic or systemic diseases 6
  • Associations between dental caries and systemic diseases, such as metabolic diseases, have been found in human and animal studies 5
