Nourishing Our Elders: A Comprehensive Guide to Geriatric Nutrition in West Africa (Nigeria and Ghana)

As Sub-Saharan Africa undergoes a demographic shift, the population of older adults aged 60 years and above is increasing significantly. In West Africa, particularly in Nigeria and Ghana, respect for elders remains a deeply rooted cultural value. However, modern dietary transitions, urbanisation, and the growing consumption of processed, energy-dense foods have contributed to a double burden of malnutrition and non-communicable diseases (NCDs) such as hypertension, type 2 diabetes, stroke, and cardiovascular disease among older adults.

Healthy ageing does not require abandoning traditional, culturally cherished foods. On the contrary, West Africa's rich agricultural heritage provides an abundance of nutrient-dense indigenous ingredients that, when prepared thoughtfully, can support vitality, preserve muscle mass, enhance cognitive function, and assist in the management of chronic conditions.

Nutritional Needs and Physiological Changes in Ageing

As the body ages, several physiological changes directly affect nutritional requirements and eating habits:

1. Reduced Metabolism and Sarcopenia

Basal metabolic rate naturally declines with age, while age-related muscle loss, known as sarcopenia, accelerates. Older adults generally require fewer calories but significantly more high-quality protein to maintain muscle mass, strength, and bone health.

2. Reduced Thirst Sensation

Ageing affects the body's ability to recognise thirst, increasing the risk of chronic dehydration, constipation, urinary tract infections, and reduced cognitive performance. Older adults may need regular reminders to drink fluids throughout the day.

3. Digestive Changes and Slower Gastric Emptying

Reduced stomach acid production and slower digestive processes can affect nutrient absorption and make high-fat or heavily refined foods more difficult to tolerate. Fibre-rich foods and adequate hydration become increasingly important.

4. Dentition and Chewing Difficulties

Tooth loss, gum disease, or poorly fitting dentures may make chewing difficult. As a result, some older adults avoid nutrient-dense foods such as meats, legumes, fruits, and vegetables, increasing the risk of nutrient deficiencies.

5. Chronic Disease Management

The prevalence of hypertension, diabetes, and cardiovascular disease rises with age. Careful management of dietary sodium, added sugars, and high-glycaemic carbohydrates is essential for maintaining health and preventing complications.

Case Study 1: Nigeria - Revitalising Traditional Diets for Senior Health

In Nigeria, traditional diets for older adults often rely heavily on refined carbohydrate-based swallows such as eba and white fufu, frequently accompanied by oil-rich and highly salted soups. Improving the nutritional quality of these meals involves emphasising complex carbohydrates, lean proteins, and nutrient-dense vegetables while reducing excessive sodium and unhealthy fats.

Key Nigerian Foods That Support Healthy Ageing

1. Unripe Plantain Porridge

Unripe plantain is rich in resistant starch, potassium, and magnesium. As a low-glycaemic staple, it helps support blood glucose control and cardiovascular health. When prepared with leafy vegetables and fish, it provides steady energy without causing rapid blood sugar spikes.

2. Nutrient-Dense Leafy Greens (Ugwu, Ewedu, Oha and Bitterleaf)

Fluted pumpkin leaves (ugwu), jute leaves (ewedu), oha, and bitterleaf are excellent sources of folate, calcium, iron, and antioxidants. Ewedu is particularly beneficial because its naturally smooth texture makes it easy for older adults with chewing or swallowing difficulties to consume.

3. Brown Beans (Oloyin) and Bambara Groundnuts

These legumes provide high-quality plant protein, dietary fibre, potassium, and iron. Preparing them as steamed moi-moi or soft bean porridge improves digestibility while preserving much of their nutritional value.

4. Fermented Dairy and Probiotics (Fura da Nono)

Traditional fermented milk (nono) combined with millet offers beneficial probiotics that support gut health, alongside calcium and B vitamins that contribute to healthy bones. Unsweetened preparations are preferable for individuals managing blood glucose levels.

5. Natural Seasonings (Iru and Dawadawa)

Fermented locust beans provide a rich umami flavour that can help families reduce reliance on sodium-rich seasoning cubes. These traditional flavourings contribute depth and complexity to meals while supporting healthier sodium intake.

Case Study 2: Ghana - Adapting Traditional Foods for Longevity

In Ghana, traditional staples such as banku, kenkey, fufu, and ampesi form the foundation of many meals. While these foods remain culturally important, large portions of refined maize and cassava products may contribute to poor blood sugar control. Healthier adaptations focus on unrefined grains, increased fish consumption, and greater intake of leafy vegetables.

Key Ghanaian Foods That Support Healthy Ageing

1. Whole Grains and Traditional Porridges

Unsieved millet porridge, such as Hausa Koko or Koko Tsale, provides fibre, magnesium, and slow-release energy when prepared with minimal added sugar. Replacing polished white rice with locally grown brown rice (ofam) can further support blood glucose management.

2. Traditional African Greens (Kontomire and Gboma)

Cocoyam leaves (kontomire) and African eggplant leaves (gboma) are rich sources of vitamins A, C, and K, as well as calcium and iron. Softly cooked kontomire stew prepared with moderate amounts of palm oil can support eye health, bone strength, and cardiovascular wellbeing.

3. Fresh and Oily Fish

Tilapia, herrings, sardines, and mackerel are excellent sources of high-quality protein and omega-3 fatty acids. These nutrients may help reduce inflammation and support cognitive health. Fish prepared in light soups is often easier to chew and digest than tougher cuts of meat.

4. Garden Eggs (African Eggplant)

Garden eggs are low in calories and rich in fibre, antioxidants, and potassium. They support digestive health, cholesterol management, and healthy blood pressure. They can be eaten boiled, roasted, mashed, or incorporated into traditional stews.

5. Hydration Through Natural Beverages

Unsweetened hibiscus tea (sobolo) infused with ginger and cloves contains beneficial polyphenols that support vascular health. Fresh coconut water provides natural electrolytes that can help maintain hydration in warm climates.

Actionable Guidelines for Caregivers

1. Modify Food Texture

Mash, mince, puree, or finely chop foods when necessary. Preparing vegetables in soups and stews can make meals easier to chew and digest while maintaining nutritional value.

2. Offer Smaller, More Frequent Meals

Rather than serving two large meals, provide four to five smaller, nutrient-dense meals and snacks throughout the day to improve appetite and nutrient intake.

3. Prioritise Hydration

Encourage a daily fluid intake of approximately 1.5 to 2 litres unless otherwise advised by a healthcare professional. Water, herbal beverages, broths, and naturally low-sugar drinks can all contribute to hydration. If frequent night-time urination is a concern, avoid excessive fluid intake immediately before bedtime.

4. Reduce Sodium and Added Sugars

Replace commercial seasoning cubes with traditional flavour enhancers such as iru and dawadawa, as well as herbs and spices. Sweeten porridges and beverages with small amounts of fruit rather than refined sugar whenever possible.

5. Encourage Protein Intake at Every Meal

Including fish, legumes, dairy products, eggs, or lean meats in regular meals helps preserve muscle mass and functional independence as people age.

6. Promote Variety and Colour

A colourful plate containing vegetables, fruits, legumes, whole grains, and healthy protein sources helps ensure adequate intake of vitamins, minerals, fibre, and protective plant compounds.

Conclusion

Supporting healthy ageing in West Africa does not require abandoning cherished culinary traditions. By thoughtfully adapting traditional Nigerian and Ghanaian meals to include more fibre-rich carbohydrates, nutrient-dense vegetables, lean proteins, and reduced sodium, families can protect the health and dignity of older adults while preserving cultural identity.

Traditional foods remain powerful tools for promoting longevity, independence, and quality of life. Combined with adequate hydration, regular physical activity, and appropriate healthcare, culturally relevant nutrition can help older adults thrive and age with strength and dignity.
