Adding vitamins to seasoning cubes does not make a poor diet healthy. And for pregnant women, the sodium question cannot be ignored.
A growing narrative in Nigeria’s public-health debate argues that seasoning cubes fortified with iron, zinc, folic acid and vitamin B12 could help tackle anaemia and neural tube defects during pregnancy.
The argument is straightforward: seasoning cubes are widely used in Nigerian households, so fortifying them could turn an everyday product into a vehicle for delivering essential micronutrients.
But that logic deserves much closer scrutiny.
A product’s popularity does not automatically make it an appropriate public-health delivery system.
The Nigerian government should therefore carefully assess proposals to expand micronutrient fortification of ultra-processed foods (UPFs), particularly when those products can also contribute significant amounts of sodium to the diet.
The maternal-health risk cannot be an afterthought
The central concern is not whether micronutrients are important. They are.
The question is whether sodium-heavy, ultra-processed products should become a major pathway for addressing maternal micronutrient deficiencies.
Some seasoning cubes can contain substantial amounts of sodium. One cube may contain as much as 1,200mg of sodium, equivalent to about 60 per cent of the World Health Organisation’s recommended maximum daily intake of 2,000mg.
And a cube is rarely used in isolation.
In many households, several cubes may be added to a meal alongside table salt and other sodium-containing ingredients. The resulting intake can quickly exceed recommended levels.
For pregnant women, this deserves particular attention because excessive sodium consumption can contribute to elevated blood pressure and fluid retention.
That matters in a country where hypertensive disorders of pregnancy are already a major maternal-health challenge.
According to research cited by Nwagha et al. (2026), hypertensive disorders account for 16.7 per cent of maternal deaths in Nigeria. These conditions can include gestational hypertension and pre-eclampsia and, in severe cases, progress to eclampsia and life-threatening complications.
A micronutrient intervention should not create or worsen another health risk.
Fortification does not fix the underlying diet
There is another problem with presenting fortified UPFs as a solution to malnutrition.
Adding selected vitamins and minerals does not remove the other nutritional characteristics of the product.
Ultra-processed foods can contain substantial amounts of sodium, added sugars, unhealthy fats and various additives, depending on the product.
That creates a potential paradox: a population can continue experiencing micronutrient deficiencies while simultaneously facing rising rates of diet-related conditions such as hypertension, obesity and cardiovascular disease.
This is the double burden of malnutrition—and Nigeria cannot afford policies that unintentionally intensify it.
The goal should not simply be to increase the number of nutrients listed on a food label. It should be to improve the overall quality and diversity of what people eat.
Nigeria’s anaemia figures demand a broader response
There is also a critical question of effectiveness.
Nigeria has already had voluntary iron fortification of bouillon products, yet anaemia remains widespread.
A comparison cited from the 2001 Food Consumption and Nutrition Survey and the 2021 National Food Consumption and Micronutrient Survey indicates that anaemia among women rose from 24.3 per cent to 55 per cent over that period.
That comparison does not, by itself, prove that bouillon fortification caused or failed to cause the change. But it does demonstrate why policymakers should demand stronger local evidence before treating fortified seasoning cubes as a major solution to anaemia.
The broader food environment matters.
The 2021 survey reportedly found that 79 per cent of Nigerian households experienced food insecurity, including 57 per cent classified as moderately food insecure and 22 per cent as severely food insecure.
When families struggle to afford food, dietary diversity is often one of the first casualties.
Animal-source foods, fruits and vegetables can become less affordable, while households increasingly depend on cheaper staple foods.
That is the problem Nigeria needs to confront—not simply the absence of synthetic micronutrients in processed foods.
The “health halo” problem
Fortification can also change how consumers perceive a product.
A seasoning cube carrying claims about iron, folic acid or other nutrients may appear healthier than an otherwise identical product without those claims.
That creates what public-health advocates describe as a “health halo.”
Research and advocacy groups have raised concerns that food manufacturers can use nutrient additions and positive nutrition messaging to improve the image of ultra-processed products.
The Global Health Advocacy Incubator, for example, has documented the development of industry-led “Positive Nutrition” approaches, including a programme associated with Unilever dating back to 2006.
The concern is not that every fortified product is inherently harmful. Rather, fortification should not become a marketing shortcut that allows the nutritional weaknesses of an ultra-processed product to disappear behind a list of added vitamins and minerals.
Public policy must be based on the total nutritional profile of foods, not isolated nutrients.
What Nigeria should prioritise instead
If the objective is to reduce anaemia, micronutrient deficiencies and maternal complications, Nigeria has safer and more direct tools available.
1. Set stronger sodium standards
Government should establish and enforce appropriate sodium limits for bouillon and other processed foods.
Manufacturers should also be encouraged—and where necessary required—to reformulate products to reduce sodium levels.
2. Strengthen front-of-pack labelling
Consumers need simple, visible information about products that are high in sodium, sugar or unhealthy fats.
Clear front-of-pack warnings could make healthier choices easier, particularly for consumers who do not have time to interpret complex nutrition panels.
3. Improve access to prenatal supplementation
Pregnant women should have reliable access to iron-folic acid supplements and multiple micronutrient supplements through primary healthcare centres and community health workers.
This targets the people who need the nutrients directly rather than relying on incidental consumption through a processed food.
4. Invest in diverse, nutrient-rich foods
Nigeria’s nutrition strategy should strengthen access to foods that naturally provide a broad range of nutrients.
That includes vegetables, fruits, legumes, whole grains and appropriate animal-source foods.
5. Support nutrition-sensitive agriculture
Agricultural fortification and biofortification efforts can focus on staple crops such as iron-rich cassava, zinc-rich maize and orange-fleshed sweet potatoes.
These approaches can improve nutrient intake without requiring consumers to increase their intake of sodium-heavy processed products.
6. Make healthy food more accessible
Food insecurity cannot be solved through fortification alone.
Policies that improve household purchasing power, agricultural productivity, food availability and access to diverse diets are essential if Nigeria wants lasting improvements in nutrition.
Home and community gardening can also help households increase access to locally grown vegetables, fruits and herbs where feasible.
The bigger question
Nigeria’s nutrition crisis is not simply a vitamin-and-mineral problem.
It is also a food access, affordability, dietary diversity and food-system problem.
That distinction matters.
If policymakers focus too heavily on delivering micronutrients through products that are already deeply embedded in diets, they risk treating a symptom while leaving the underlying dietary environment unchanged.
Fortification has a legitimate role in public health. But not every fortified product is automatically a good nutrition intervention.
Nigeria should demand rigorous local evidence, assess the full nutritional profile of fortified products and consider potential unintended consequences before expanding such programmes.
The country needs policies that make healthy food easier to access—not policies that make ultra-processed food appear healthier.
Nigeria cannot fortify its way out of an unhealthy food system. The stronger path is dietary diversity, safer food environments, targeted maternal supplementation and a food system capable of putting nutritious whole foods within reach of ordinary households.
