What foods contain vitamin D?

Vitamin D can be found in a variety of foods, mainly including the following categories:

1. Fish and seafood: Deep-sea fish such as salmon, mackerel, trout, and tuna are excellent sources of vitamin D. In addition, fish liver oils are also very rich in vitamin D.

2. Eggs and dairy products: Egg yolks contain a certain amount of vitamin D. Dairy products such as milk, yogurt, and cheese that are fortified with vitamin D also serve as good sources for supplementing vitamin D.

3. Mushrooms: Certain types of mushrooms, such as white mushrooms, can naturally produce vitamin D when exposed to ultraviolet light. There are also mushroom products on the market specifically treated with UV light to increase their vitamin D content.

4. Fortified foods: Many breakfast cereals, soy milk, orange juice, and other food products are enriched with vitamin D during processing to enhance their nutritional value.

5. Grains: Although the vitamin D content in grains is relatively low compared to other foods, corn, glutinous rice, barley, and others do contain a certain amount of vitamin D.

In daily life, it is important to maintain a balanced diet and engage in appropriate outdoor activities to promote the body's natural synthesis of vitamin D.
