In Nigeria, various foods contain Vitamin D, though it's important to note that very few foods naturally provide significant amounts of Vitamin D. However, some sources of Vitamin D in Nigerian cuisine include:

1. Fish: Certain types of fish, such as mackerel (Titus fish), sardines, and salmon, contain Vitamin D. These are commonly consumed in Nigeria and can contribute to Vitamin D intake.

2. Eggs: Egg yolks contain small amounts of Vitamin D, making them a source of this nutrient.

3. Mushrooms: While not a staple in all Nigerian dishes, mushrooms exposed to sunlight can naturally produce Vitamin D, though their availability might vary.

4. Fortified Foods: Some foods in Nigeria, such as fortified cereals, margarine, or powdered milk, might be fortified with Vitamin D. Checking food labels can help identify fortified products.

However, obtaining adequate Vitamin D solely from food sources can be challenging, especially in regions where sunlight exposure is limited. The primary source of Vitamin D for most people is through sunlight exposure, as the skin produces Vitamin D when exposed to sunlight.

It's important for Nigerians, as well as individuals in regions with limited sun exposure, to maintain a balanced diet, spend time outdoors for sunlight exposure, and, if necessary, consider supplements under the guidance of a healthcare professional to ensure adequate Vitamin D levels.
