The Primary Culprit: Poor Dietary Habits
Scurvy is fundamentally a nutritional disease, and the most direct lifestyle factor contributing to it is a poor diet that lacks sufficient vitamin C. Humans cannot synthesize vitamin C and must obtain it from external food sources, primarily fresh fruits and vegetables. When a person's diet is devoid of these essential items for at least three months, their body's vitamin C stores become dangerously depleted.
The Impact of Modern Diets
In the modern era, poor dietary habits are not limited to long sea voyages but are often a product of other lifestyle choices. A dependence on fast food, highly processed meals, and carbonated beverages, combined with a sedentary lifestyle, has led to a decrease in fresh fruit and vegetable consumption. This can occur across different socioeconomic groups, including individuals who are overweight or obese but still suffer from nutritional deficiencies because their diet lacks density, not just calories. Restrictive eating patterns, whether due to personal preference, mental health issues like anorexia nervosa, or even avoidance/restrictive food intake disorder (ARFID) in children, also significantly increase risk.
Lifestyle Habits That Increase Vitamin C Needs
Certain habits actively increase the body's need for vitamin C or hinder its absorption, making even a borderline diet insufficient.
Smoking and Vitamin C Depletion
Cigarette smoking is a major risk factor for scurvy, as the harmful compounds in smoke deplete the body's vitamin C levels. Smokers require an additional 35 mg of vitamin C daily compared to non-smokers to maintain adequate levels, yet many are unaware of this increased need. This increased depletion, combined with the often poorer dietary habits of smokers, significantly raises their risk of deficiency.
Alcoholism and Nutritional Neglect
Chronic alcoholism is strongly associated with malnutrition and vitamin C deficiency. Alcohol can interfere with the absorption of vitamins in the digestive system. Furthermore, individuals with a long-term dependency on alcohol often neglect proper nutrition, further exacerbating the deficiency. Multiple case studies have documented scurvy in individuals with histories of heavy alcohol use and poor food intake.
Poor Cooking Practices and Food Preparation
Vitamin C is a water-soluble and heat-sensitive nutrient. This means improper food preparation can destroy a significant amount of the vitamin content. While eating fresh, raw fruits and vegetables is the best way to preserve vitamin C, cooking methods matter. Boiling and prolonged storage of produce can lead to nutrient loss. Healthdirect.gov.au recommends lightly steaming vegetables to retain more of the vitamin.
Socioeconomic and Environmental Factors
An individual's environment and financial situation can greatly influence their access to vitamin C-rich foods. Low socioeconomic status and food insecurity often correlate with a diet lacking fresh produce, as it can be more expensive and less readily available than processed foods. For vulnerable populations, such as the elderly living alone or refugees, obtaining consistent fresh fruit and vegetables can be a major challenge, leading to long-term dietary deficiencies.
Comparison of Lifestyle Choices and Scurvy Risk
| Lifestyle Factor | Scurvy Risk Level | Rationale |
|---|---|---|
| Balanced Diet (rich in fresh produce) | Low | Consistent intake of vitamin C meets daily requirements and replenishes body stores. |
| Heavy Smoking | High | Smoking depletes vitamin C and increases daily requirements significantly. |
| Chronic Alcoholism | High | Interferes with absorption and is often coupled with poor nutrition. |
| Restrictive Diet (e.g., allergies, eating disorder) | High | Limited food choices can exclude most vitamin C sources. |
| Reliance on Cooked/Processed Foods | Moderate to High | Vitamin C is destroyed by heat during cooking and processing. |
| Limited Food Access (low income) | Moderate to High | Financial and environmental barriers prevent access to fresh, vitamin C-rich produce. |
| Pregnancy/Breastfeeding with Poor Diet | High | The body's vitamin C needs increase significantly during these periods. |
Conclusion: Reversing and Preventing Scurvy
While often viewed as a historical ailment, scurvy remains a relevant health concern driven by several modern lifestyle factors. A prolonged dietary insufficiency of vitamin C, exacerbated by habits such as smoking and alcohol abuse, is the root cause. Other contributing factors include restrictive eating patterns and socio-economic barriers to fresh food access. Fortunately, scurvy is easily preventable and treatable with proper dietary management and vitamin C supplementation. By prioritizing fresh fruits and vegetables, and addressing underlying lifestyle issues, individuals can effectively mitigate their risk. For those at high risk, or experiencing symptoms, consulting a healthcare professional is the best course of action to diagnose and treat the condition effectively.

What Lifestyle Factors Contribute to Scurvy?
- Poor Dietary Intake: The most significant lifestyle factor is consistently not eating enough fresh fruits and vegetables.
- Smoking: This habit actively depletes the body's vitamin C, raising the daily requirement for this nutrient.
- Chronic Alcoholism: Heavy alcohol use impairs vitamin C absorption and often accompanies poor nutritional choices.
- Restrictive Eating Patterns: Diets that intentionally or unintentionally exclude major sources of vitamin C, such as seen with certain eating disorders or food allergies, can lead to deficiency.
- Socioeconomic Hardship: Lack of affordable access to fresh produce contributes to poor dietary intake and higher scurvy risk.
- Infant Feeding Practices: Providing infants with cow's milk rather than breast milk or fortified formula can pose a risk.
- Aging and Isolation: Elderly individuals, especially those who live alone, may experience poor appetite or limited access to fresh food, increasing their vulnerability.
