Cuba: primary care, food supply and metabolic health

Cuba offers an important Caribbean comparison: universal health coverage and a nationwide family-doctor system coexist with population ageing, noncommunicable disease and periods of severe food and medicine constraint. Its experience shows that clinical access, food availability and metabolic health must be considered together.

At a glance

  • Primary care: PAHO describes Cuba’s Family Doctor and Nurse Program as the foundation of universal coverage, including remote communities.
  • Diabetes: Cuba reported adult prevalence of high blood glucose or diabetes of 6.7% in 2020.
  • Hypertension: Reported prevalence was 23% in 2020.
  • Ageing: People aged 65 and older represented 15.8% of the population in 2020, increasing demand for long-term NCD care.

Cuban meals and nutritional strengths

Beans, rice, root crops, plantain, vegetables, fruit, fish, eggs and stewed foods remain recognizable components of Cuban eating. Beans add fibre and protein to meals built around rice or root crops. Home preparation can support metabolic health when vegetables and legumes remain substantial and sugary drinks, refined baked goods and heavily processed products are less frequent.

Food scarcity complicates simple dietary advice. When households face limited choice, irregular supply or high prices, the priority is adequate energy, protein and micronutrients. A nutritionally preferable diet must also be obtainable.

Food supply, rationing and health

Cuba’s rationing system has historically aimed to protect minimum access, but shortages, import constraints, agricultural limitations and disruptions in electricity and transport can reduce variety and continuity. Food insecurity can coexist with diabetes and hypertension: inexpensive refined calories may be more available than legumes, vegetables, fruit or animal-source foods.

Nutrition policy should therefore connect household access with agricultural production, storage, transport and reliable energy. Advice that ignores scarcity can increase frustration without improving health.

Sugar, liver health and individual risk

Frequent excess intake of added sugar, especially in beverages, can contribute to higher triglycerides, insulin resistance and fatty-liver risk. No single food explains Cuba’s chronic-disease burden. Ageing, body composition, activity, alcohol, tobacco, medicines, sleep, stress and interrupted treatment all matter.

Inherited variation can modify individual susceptibility, but Cuban nationality or racial identity is not a diagnosis. The country’s primary-care network is well placed to use family history, blood pressure, glucose, lipids, kidney function and liver indicators for individual assessment.

Agriculture and resilience

Cuba produces sugarcane, tobacco, roots and tubers, rice, beans, fruit, vegetables and livestock, with urban agriculture also contributing in some areas. Improving yields and diversity requires dependable fuel and electricity, water management, soil health, seed access, farm incentives, storage and transport.

Local production cannot resolve every shortage, but stronger links between farms, schools, hospitals and neighbourhood markets can reduce loss and protect access to minimally processed food.

Priorities for progress

  • Use the family-doctor network for early detection and continuity of diabetes and hypertension care.
  • Protect access to essential medicines, insulin and diagnostic supplies during shortages.
  • Increase reliable availability of beans, vegetables, fruit, roots, eggs and other nutrient-dense foods.
  • Strengthen agricultural storage, energy resilience and farm-to-market transport.
  • Publish current surveillance with clear dates, methods and population definitions.
