Blood Sugar Spikes: 7 Nigerian Foods That Can Increase Your Risk of Diabetes
In the heart of Lagos, our plates are a reflection of our rich culture—vibrant, generous, and full of flavour. But as our lifestyles have become faster and more reliant on convenience, some of our most beloved dietary staples are quietly contributing to a growing health crisis: Type 2 Diabetes.
Diabetes is a silent disease in its early stages. It often begins with a long “warning” period called pre-diabetes, where your blood sugar is consistently high but not yet in the diabetic range. This stage has no symptoms, but it’s a critical window of opportunity. It’s your body’s signal that it’s struggling to manage sugar, and that it’s time to make a change.
This is not a list to make you fear your food. This is a guide to empower you with knowledge. It’s about understanding which common Nigerian foods and eating habits can put you on the path to high blood sugar, so you can enjoy them more mindfully. The first, most essential step is to get a health checkup to know your numbers, especially with an HbA1c test. Once you have that crucial data, you can use this guide to make smarter choices for your long-term health.
1. Sugary Drinks (Sodas, Malt Drinks, and Packaged Juices)
This is, without a doubt, the #1 offender and the easiest change to make. These drinks are a staple for quenching thirst in the Lagos heat, but they are metabolic poison.
-
Why They’re a Risk: These beverages are essentially “liquid sugar.” They contain a massive amount of refined sugar and zero fiber. When you drink them, this sugar is absorbed into your bloodstream almost instantly, causing a huge, rapid spike in your blood sugar. Your pancreas is then forced to release a flood of insulin to cope. Doing this day after day is a direct path to developing insulin resistance, the hallmark of Type 2 diabetes.
-
Smarter Choices:
-
Make water your primary drink. It’s the best way to hydrate.
-
Opt for homemade, unsweetened zobo or lemon water.
-
If you want fruit, eat the whole fruit instead of drinking the juice. The fiber in the whole fruit slows down sugar absorption.
-
2. Highly Refined “Swallows” (Eba, Semovita, Pounded Yam from Powder)
Swallows are the heart of many Nigerian meals, but the way most are made today is a problem for blood sugar control.
-
Why They’re a Risk: Modern swallows like eba (from highly processed garri), semovita, and pounded yam made from instant flour are highly refined carbohydrates. They have been stripped of their natural fiber. This means they are digested very quickly and converted into glucose, causing a significant and prolonged spike in your blood sugar.
-
Smarter Choices:
-
Portion control is key. Reduce the size of your swallow and increase the portion of your vegetable-rich soup.
-
Explore higher-fiber alternatives like swallows made from whole wheat flour, unripe plantain flour, or oatmeal (oatmeal fufu).
-
Always eat your swallow with a nutrient-dense soup like ogbono or efo riro to add fiber and slow down digestion.
-
3. White Bread and Sweetened Baked Goods (Agege Bread, Meat Pies, Doughnuts)
These are the go-to items for a quick breakfast or a snack on the move.
-
Why They’re a Risk: White bread, including our beloved Agege bread, is made from refined white flour, which acts just like sugar in the body. It digests rapidly and spikes blood sugar. Other baked goods like meat pies, sausage rolls, and doughnuts are a double threat: they contain refined flour and a significant amount of sugar and unhealthy fats.
-
Smarter Choices:
-
Choose 100% whole wheat bread instead of white bread.
-
Treat sweet baked goods as an occasional indulgence, not a daily snack.
-
Opt for healthier snacks like a handful of roasted groundnuts or a hard-boiled egg.
-
4. Large Portions of White Rice
White rice is a staple on almost every Nigerian table, from simple rice and stew to the celebratory jollof rice.
-
Why It’s a Risk: Like white bread, white rice is a refined grain with a high glycemic index, meaning it raises blood sugar quickly. The primary issue in our culture is portion size. We often consume very large portions of rice, which delivers a massive carbohydrate load to our system.
-
Smarter Choices:
-
Drastically reduce your rice portion. A good guide is to limit it to the size of your clenched fist.
-
Fill the rest of your plate with vegetables and lean protein.
-
Switch to local whole-grain alternatives like Ofada rice or Abakaliki rice when possible.
-
5. Fried Ripe Plantain (Dodo)
Sweet, caramelized, and delicious, dodo is a favourite side dish for many.
-
Why It’s a Risk: This is a metabolic double-whammy. As plantain ripens, its starch converts to sugar. So, you are starting with a high-sugar food. Deep-frying it in oil adds a large number of calories and unhealthy fats, which contributes to weight gain and inflammation—both key drivers of insulin resistance.
-
Smarter Choices:
-
Enjoy dodo as a treat, not a daily staple.
-
Opt for unripe or slightly ripe plantain, which is much higher in fiber and lower in sugar.
-
Try healthier cooking methods like baking or air-frying your plantain instead of deep-frying.
-
6. Sweetened Yogurts and Processed Breakfast Cereals
These are often marketed as “healthy” breakfast options, but many are packed with hidden sugars.
-
Why They’re a Risk: A small cup of sweetened yogurt or a bowl of popular processed cereals (like “Golden Morn”) can contain as much sugar as a bottle of soda. Starting your day with this sugar rush sets you up for a blood sugar rollercoaster and cravings for the rest of the day.
-
Smarter Choices:
-
Choose plain, unsweetened Greek yogurt and add your own fresh fruit.
-
Opt for natural, whole-grain cereals like oatmeal.
-
Consider a protein-rich breakfast like eggs to keep you full and your blood sugar stable.
-
7. Heavily Sweetened Garri
Soaking garri with sugar and milk is a classic Nigerian comfort food and a quick snack.
-
Why It’s a Risk: Garri itself is a processed carbohydrate. When you then add multiple spoons of sugar, you are creating a simple, high-sugar meal with very little nutritional value that will cause a rapid and significant blood sugar spike.
-
Smarter Choices:
-
If you must drink garri, do so without adding any sugar.
-
Add roasted groundnuts to provide some protein and healthy fats, which will help to slow down the absorption of the carbohydrate.
-
Consider this a very occasional snack, not a regular meal.
-
Knowledge is the First Step to Prevention
This list is about making you a more conscious consumer. By understanding how these foods affect your body, you can make small, sustainable changes that will have a huge impact on your risk of developing diabetes.
But your entire strategy must be built on data. You cannot manage a risk you don’t know you have. The HbA1c test is the definitive way to understand your current blood sugar status. It is a fundamental part of a comprehensive health checkup from Healthtracka.
