Sickle cell disease: Beyond ‘eat better’

n n

“Eat better.” It is one of the most common pieces of advice given to people living with chronic illness. Eat more vegetables. Increase protein. Reduce processed foods. Stay hydrated. Support your immune system.

n

On the surface, it sounds reasonable. Even empowering. But what if “eat better” ignores the structural realities shaping who can access nutritious food in the first place? When discussing nutrition in Sickle Cell Disease, we must move beyond individual responsibility and examine the politics of food access.

n

Chronic illness and nutritional demand

n

SCD is characterised by chronic inflammation, haemolytic anaemia, vascular injury, and increased metabolic stress. The body is often in a state of repair. This can increase nutritional demand, particularly for: protein, folate, zinc, vitamin C, magnesium and adequate hydration.

n

In theory, supporting the body with balanced, nutrient-dense food may help maintain resilience and recovery capacity. In practice, the question is: who can afford to eat this way consistently?

n

The cost of healthy eating

n

Fresh produce costs more than ultra-processed alternatives. Lean proteins, oily fish, nuts, seeds, and fresh fruit are often significantly more expensive than calorie-dense packaged foods.

n

For families managing SCD, the financial burden can already be substantial: hospital travel, prescription costs, time off work, specialist appointments and heating costs during cold weather (important for preventing crises).

n

Adding a nutritionally optimal diet to that list can become economically unrealistic. Telling a family managing recurrent hospital admissions to “just buy organic vegetables” or “eat more salmon” can sound detached from reality.

n

Food deserts and geographic inequality

n

Access is not only about income, but it is also about geography. In parts of the UK, low-income areas have fewer supermarkets and more fast-food outlets. These are often described as food deserts, neighbourhoods where fresh, affordable food is harder to obtain. The pattern is not random. Food inequality frequently maps onto race and class.

n

SCD predominantly affects Black communities in the UK. When chronic illness intersects with food deserts and economic strain, health disparities widen. The advice remains the same. The conditions do not.

n

Hospital food and chronic illness

n

Another rarely discussed issue is hospital nutrition. Patients admitted for vaso-occlusive crises may spend days or weeks in the hospital. Yet hospital food rarely reflects the increased protein and micro-nutrient needs of someone in recovery from inflammatory stress.

n

Meals may be carbohydrate-heavy, low in fresh produce, and designed for cost-efficiency rather than therapeutic value. If nutrition is genuinely considered part of chronic disease management, hospital food standards must reflect that reality.

n

Strengthening the Nigerian context

n

Nigeria carries one of the highest global burdens of SCD. The World Health Organisation estimates that approximately 150,000 children are born annually with SCD in Nigeria (WHO, 2023).

n

At the same time, Nigeria faces significant food inflation and economic volatility. National Bureau of Statistics data (2023) show sustained rises in staple food prices, affecting household purchasing power.

n

Families managing SCD may simultaneously face out-of-pocket healthcare costs, limited specialist access, inconsistent blood supply infrastructure and rising food prices.

n

In this context, advising increased protein intake or diversified micro-nutrient consumption without structural support can become unrealistic.

n

Rural-urban disparities further complicate the issue. Access to fortified foods, refrigeration, and diverse produce varies significantly. Nutritional guidelines developed in high-income settings cannot simply be transplanted without considering infrastructure realities.

n

The problem with individualised messaging

n

Public health messaging often frames nutrition as personal choice. But choice operates within constraint. A parent choosing between clinic transport and fresh fruit is not demonstrating neglect — they are navigating structural scarcity.

n

If nutrition supports inflammation control and wound healing, then equitable food access must be viewed as part of healthcare infrastructure, not merely lifestyle guidance.

n

Rethinking food as health policy

n

Should nutritional screening be routine in haematology clinics? Should governments subsidise nutrient-dense foods for families managing chronic illness? Should hospital procurement standards reflect inflammatory disease requirements?

n

Nutrition cannot cure SCD, but ignoring food inequality perpetuates preventable disparity. When a disease disproportionately affects historically marginalised communities, food access becomes a political issue.

n

Food is not just fuel. In chronic illness, it is part of repair. And when repair becomes a privilege, inequality deepens.
