What vitamin is recommended to be consumed in fortified foods for adults over 50?

Vitamin B12 is recommended to be consumed in fortified foods for adults over 50 because as individuals age, their ability to absorb this vitamin from food decreases. This can occur due to changes in stomach acidity, which affect the digestion of food sources that naturally contain B12, such as meat, fish, and dairy products. Additionally, certain medications that are common among older adults can further impede B12 absorption.

Fortifying foods with vitamin B12 ensures that older adults can maintain adequate levels, which are crucial for preventing deficiencies that can lead to health issues such as anemia and cognitive decline. While vitamins D and A are important for health, the specific need for B12 fortification addresses a prevalent issue in this age group regarding nutrient absorption.
