Diabetes Diet: Best Nigerian Foods to Eat and Avoid

A diabetes diet involves eating a balanced diet that is made of carbohydrates, fat, and protein in the right proportion.

If you have diabetes, your risk of having uncontrolled blood sugar and heart disease is pretty high.

This is why the National Institute of Diabetes, Digestive, and Kidney Diseases recommends following a healthy meal plan and being physically active to keep your blood sugar levels within the target range [1].

To help you stick to healthy food options, you should eat foods locally available in Nigeria.

 Here is a list of the best foods for people living with either type 1, type 2, or gestational diabetes.

12 best foods for diabetics in Nigeria

1. Beans

Beans like black-eyed peas, bambara nuts, and soybeans are incredibly nutritious for diabetics. 

They are rich in dietary fiber and protein that help satisfy the appetite and reduce cravings.

They also have a low glycemic index, which is important for managing and preventing diabetes.

Low glycemic index foods cause a slow rise in blood sugar, while high glycemic index foods cause a sharp rise in blood sugar and should be avoided in diabetes.

Beans are also versatile and contain iron, B-vitamins, magnesium, and potassium.

A study found that roasted soybean powder supplementation reduced fasting blood glucose and serum lipid levels in people with type 2 diabetes [2].

In another study, researchers found that beans contain complex carbohydrates that digest slowly and help regulate blood glucose and insulin after meals [3].

You can add roasted soybeans powder to your tea, pap, porridge, or stew.

2. Whole grains

Whole grains are rich in fiber and nutrients that keep you full and promote satiety.

They are high fiber foods and are great for diabetes because they are digested slowly – preventing a sharp rise in blood sugar levels.

Whole grains are also low glycemic index foods and are great for diabetics.

Examples of whole grains to include in your diabetes diet are:

3. African yam bean

The African yam bean is a legume that grows both tubers and seeds on the same plant.

The bean seeds and tubers are rich in fiber and resistant starch – making them a good carb option for a diabetes diet.

You can add the dried powder to your stew, soup, or pap, or eat them in a porridge.

4. Green leafy vegetables

Vegetables are low in carbohydrates and rich in nutrients that help repair the body cells and prevent diabetes.

They are rich sources of fiber, vitamin C, folate, iron, potassium, magnesium, and antioxidants.

Antioxidants are substances that protect the body cells against damage by disease-causing free radicals.

Studies have found that the antioxidant properties of leafy vegetables may help people with diabetes [4].

Another study found that moringa leaves can help reduce blood sugar levels in diabetic patients [5].

Examples of leafy vegetables to include in your diet are:

  • Pumpkin leaf (ugu)
  • Jute leaf (ewedu)
  • Moringa leaf
  • Okra
  • Cabbage
  • Spinach
  • Broccoli
  • Scent leaf
  • Bitter leaf
  • Oha leaf
  • Lettuce
  • Amaranth
  • Waterleaf
  • Garden egg

You can add them to your soups, stews, salads, or porridge.

5. Fatty fish

Sardines, salmon, tuna, and mackerel are good examples of fatty fish that are rich in omega-3 fatty acids.

Omega-3 fatty acids contain DHA and EPA that help protect the heart and prevent the development of heart disease.

One study found that eating fatty fish may help regulate glucose levels in obese patients and prevent the development of type 2 diabetes [6].

You should eat fatty fish; roasted, grilled, baked, or boiled. Avoid frying.

6. Lean protein

For a balanced diabetes diet, your plate should consist of leafy green vegetables, protein, and carbs. 

Lean protein is ideal for people with diabetes because they contain little fat.

Examples of lean protein to include in your diet are:

  • Lean meat
  • Goat meat
  • Gizzard
  • Catfish
  • Tilapia
  • Shrimp
  • Chicken or turkey without the skin
  • Meat substitutes, such as tofu 

7. Nuts 

Peanuts, walnuts, and cashews are incredibly healthy snacks for diabetics.

They contain lots of fiber, protein, and healthy fats that keep you full and prevent overeating. However, be careful of your portion size; as nuts are rich in fat.

Also, several studies have found that people who eat nuts have a lower incidence of heart disease, cancer, and diabetes [7].

You can eat nuts as a snack or sprinkle them as toppings on your yogurt or smoothies.

8. Low-fat milk or yogurt 

For diabetics, low-fat dairy is ideal as it contains all the healthy nutrients in a low-calorie package.

You should opt for low-fat probiotic yogurt, as studies have found that the healthy bacteria (lactobacillus and bifidobacterium) found in them can help decrease bad cholesterol levels in type 2 diabetes people [8].

You can add milk or yogurt to your pap, pudding, fresh fruits, or smoothies. Always, make sure to choose the sugar-free varieties.

9. Fruits 

Fruits are rich in fiber, vitamin C, folate, potassium, and antioxidants. 

However, diabetics should practice portion control when consuming fruits because of their sugar content. 

It is best to choose low-calorie fruits that are low in carbohydrates but high in fiber.

Examples of healthy fruits to include in your diabetes diet are:

  • Avocado
  • Lemon
  • Orange
  • Grape
  • Strawberries
  • Baobab

10. Cocoyam

Cocoyam also called taro is a good low glycemic index food for people with diabetes.

It is full of fiber and contains 12% of resistant starch – a special type of starch that humans cannot digest.

Its rich content of fiber and resistant starch helps to slow digestion and reduce blood sugar spikes after meals [9].

You can eat boiled cocoyam or eat them as fufu with any vegetable sauce of your choice.

11. Unripe plantain

Just like cocoyam, unripe plantains are rich in resistant starch that causes a gradual rise in blood sugar after meals.  

Plantains are a rich source of fiber, vitamin C, potassium, and magnesium.

They are very versatile and can be eaten boiled, grilled, or as plantain fufu.

12. Sweet potato 

Sweet potatoes are rich in fiber and rank lower on the glycemic index scale than white potatoes.

This makes them a great carb option for people with diabetes, as they release their sugar slowly and do not cause a spike in blood sugar levels.

Also, they are great sources of vitamin A and C, potassium, and protein.

However, always practice portion control with sweet potatoes and take care not to overeat them.  

You can enjoy sweet potatoes, boiled, baked, or grilled. For a balanced diabetes diet, add leafy veggies, and a source of lean protein.

Foods to avoid

One method to manage diabetes is by learning to differentiate between low glycemic index foods and high glycemic index foods. 

Since high glycemic index foods cause a sharp spike in blood sugar levels after meals, it is best to reduce portion size or eat them with high fiber options, such as leafy vegetables. 

Examples of high glycemic index foods include:

  • Sugar and sugary foods
  • White bread
  • sugary soft drinks
  • White potatoes
  • White rice
  • Pineapple
  • Popcorn
  • Melons

People with diabetes may also choose to limit the following foods and drinks:

Fried foods 

Fried foods are high in saturated fat and trans fat. Both of which are linked to a higher risk of heart disease. 

Foods like french fries, chips, and fried puff all contribute to weight gain that worsen diabetes.

Salty foods 

Salty foods like processed meats are high in sodium, which may lead to high blood pressure and worsen diabetes symptoms.

Refined foods 

Foods like breakfast cereals, cake, candy, biscuits, baked goods, and ice cream are high in added sugar which can impact blood sugar negatively.

Carb-heavy foods 

Cassava fufu, garri, bread, pounded yam, semovita, tuwo shinkafa, etc. are examples of carbohydrate-heavy foods that should be limited.

They digest quickly and cause a sharp rise in blood sugar levels after meals; leaving you more hungry afterward. 

If you must eat any carb-heavy food; make sure to combine it with lots of veggies and lean protein.

Sugar-sweetened beverages 

Beverages with added sugars, such as fruit juice, soda, and sports or energy drinks, lack important nutrients but cause blood sugar levels to spike.

Drink water instead of sweetened beverages and consider using a sugar substitute (stevia, Truvia, etc.) in your coffee or tea.


Drinking alcohol in moderation may not have any serious side effects in people with diabetes.

However, if you’re on insulin shots or insulin secretagogues, alcohol may cause your blood sugar to drop too low – causing hypoglycemia.

The Centers for Disease Control and Prevention (CDC) recommend that women should limit alcohol to one drink per day, while men can have up to two drinks per day [10]

The bottom line

Incorporating these healthy foods into a balanced diabetes diet will help your body fight off many diseases, such as:

  • High blood pressure
  • High cholesterol
  • Metabolic disorders
  • Obesity
  • Inflammation 

Remember to be physically active by engaging in simple exercises like walking, swimming, and house chores.
