From a genetic and evolutionary nutrition standpoint, food was never random.
Our ancestors did not eat based on taste alone, they ate based on season, ecology, and how the body responds at the cellular and metabolic level.
Different soup thickeners were selected not just to “make soup draw,” but because of how their phytochemicals, fibers, and nutrients interact with digestion, blood sugar regulation, immune response, and the gut microbiome.
That is why certain thickeners were used more during the rainy season when microbial exposure is higher and the gut needs more support, while others were preferred in the dry season for energy density, storage stability, and sustained satiety, and some also supports the man's joystick for amazing interhouse sports with its zinc density.
In today’s society, many people think any thickener is fine as long as it gives texture. One function. One understanding. But that is not how our ancestors approached it.
What we now reduce to “draw soup” was once a structured system of applied food science, built on observation, repetition, and intergenerational knowledge.
To be honest, I was also losing touch with some of this knowledge until I became intentional about reconnecting and the need for documentation.
Once you begin to ask questions, you realize that even many elders today no longer hold these distinctions the way they used to.
Growing up, I saw clearly that these things were not random. The type of soup cooked, the thickener used, and even the time of the year all followed a pattern. Soups like oha, onugbu, nsala, and ogbono were not just cultural dishes, they were structured combinations of plants that worked together to support the body.
Now let us organize the major traditional thickeners properly.
1. Seed-based thickeners (high fiber, metabolic regulators, best for dry season and energy stability)
These are dense in soluble fiber and bioactive compounds, giving strong satiety and regulating glucose absorption.
a. Achi (Brachystegia eurycoma): used in oha, nsala, and onugbu. Best in dry season when lighter soups still need structure. Supports digestion and gut motility through high fiber.
b. Ofo/Ofor (Detarium microcarpum): neutral in taste, used across soups. Suitable year-round. Supports mineral balance, gut health, and mild astringent function.
c. Ukpo (Mucuna sloanei): used in ukpo soup and vegetable soups. Best in rainy or cooler periods due to its heaviness. Supports blood health and satiety but requires proper processing.
d. Akparata (Afzelia africana): used in ofe akparata and mixed soups. Best during harvest seasons. Supports digestion and immune function.
e. Ogbono (Irvingia gabonensis): widely used, especially in dry season due to its lipid content. Provides energy, supports satiety, and regulates metabolism.
f. Okobo (Mucuna variant): now rare. Traditionally used in specific communities, especially in lean seasons for nutritional support.
2. Tuber-based thickeners (gentle, gut-supportive, best for rainy season and digestive balance)
These are softer and support microbiome health through resistant starch.
a. Ede (Cocoyam – Colocasia/Xanthosoma): the most common thickener for oha and onugbu. Best in rainy season due to availability and gut-friendly properties. Supports digestion and microbial balance.
b. Ji (Yam paste – Dioscorea species): used mainly in nsala. Best during harvest season. Provides clean energy and supports electrolyte balance.
3. Mucilaginous thickeners (hydration, gut lining protection, best for hot season)
a. Okra (Abelmoschus esculentus): used fresh or dried. Best in hot weather due to its hydrating and cooling effect. Supports gut lining and blood sugar regulation.
4. Protein and lipid-rich thickeners (energy-dense, tissue support, all-season but especially high-demand periods)
a. Egusi (Citrullus colocynthis): used across seasons. Provides protein, fats, and supports tissue repair and satiety.
b. Usu (often used locally for certain wild or lesser-known seed thickeners) is sometimes combined with egusi to enhance texture and depth, adding extra fiber and subtle binding properties to soups while improving satiety and digestive balance.
5. Fermented and functional enhancers (microbial and digestive support)
a. Ugba/Ukpaka (Pentaclethra macrophylla): not a primary thickener but adds body and complexity. Supports gut health through fermentation and enzyme activity.
6. Spice-thickener hybrids (bioactive support, immune and digestive function)
a. Uziza (Piper guineense): used in uziza and mixed soups. More common in rainy periods. Supports digestion, circulation, and antimicrobial defense.
Now look at the structure.
Some thickeners were selected for fiber and metabolic control. Some for energy. Some for gut health. Some for season.
This was not guesswork.
During rainy seasons, cocoyam-based thickeners and leafy soups dominated because they supported digestion and microbial balance.
During dry seasons, seed-based thickeners like ogbono and achi were preferred because they stored well and provided sustained energy.
Even the soups followed this logic.
Oha and onugbu aligned with ede and achi for gut support.
Nsala used yam for light digestion.
Ogbono and egusi supported energy and satiety.
What we are losing is not just food variety, but a system that understood how plants interact with the body across seasons and conditions.
Many of these thickeners like akparata, okobo, and properly processed ukpo are becoming rare, not because they are not useful, but because the knowledge required to use them is fading, and we the processing as hectic.
This is not just cultural loss.
It is metabolic loss. It is ecological loss. It is knowledge loss.
Because when everything becomes “any thickener,” you erase the intelligence behind the system.
It is biochemistry, seasonality, and survival knowledge combined.
Let me end with a simple question.
How many of these do you still remember, not just by name, but by how and when they were used, if there is any missing out please comment and tell us more?
