Which food is rich in vitamin B12 and appropriate for a client with chronic gastritis?

Liver is an excellent source of vitamin B12 and is particularly beneficial for clients with chronic gastritis who may have difficulty absorbing this essential nutrient due to the condition. Vitamin B12 plays a critical role in the formation of red blood cells and the maintenance of the nervous system. Individuals with chronic gastritis can suffer from decreased intrinsic factor production, which is necessary for vitamin B12 absorption in the intestines. Therefore, consuming foods high in vitamin B12, such as liver, can help mitigate deficiencies.

In contrast, the other food choices provided, such as nuts, corn, and apples, contain minimal to no vitamin B12. Nuts and corn may offer other beneficial nutrients but do not serve as a reliable source of B12, which makes them less suitable for someone needing to boost their intake of this vital vitamin due to gastritis. Apples, while healthy, also lack significant amounts of vitamin B12. Thus, liver stands out as the most appropriate option for ensuring adequate vitamin B12 levels in this context.
