Low vitamin B12 levels, or a vitamin B12 deficiency, can stem from insufficient intake through diet. Many foods contain B12, but a deficiency often arises from excluding key sources.
Dietary Causes of Low B12
A significant reason for low B12 is a diet lacking foods rich in this vitamin. Specifically, those who avoid meat, fish, and dairy products are at higher risk. These food groups are commonly the primary sources of dietary vitamin B12.
- Meat: Beef, chicken, pork, and organ meats are excellent sources.
- Fish: Salmon, tuna, and other seafood provide substantial amounts.
- Dairy: Milk, cheese, and yogurt contribute to B12 intake.
People following strict vegetarian or vegan diets often need to supplement B12 to maintain healthy levels. This is because plant-based foods generally do not contain this vitamin.
Understanding Vitamin B12 Deficiency
It's important to note that low B12 isn't solely due to diet. Other underlying health conditions can also contribute. However, based on the provided reference, dietary intake is a primary factor in developing a B12 deficiency.
