Question 2

Identify characteristics of individuals who are particularly susceptible to a vitamin B12 deficiency and explain why.

Accepted Answer

Individuals who are particularly susceptible to a vitamin B12 deficiency are those who follow a strict vegetarian or vegan diet, as vitamin B12 is primarily found in animal products. Additionally, older adults and individuals with gastrointestinal disorders such as Crohn's disease or celiac disease may also be at a higher risk for vitamin B12 deficiency due to decreased absorption of the vitamin from food.

Pregnant and breastfeeding women may also be susceptible to vitamin B12 deficiency as their bodies require higher levels of the vitamin during these periods. Furthermore, individuals who have undergone weight loss surgery, which can affect the body's ability to absorb nutrients, may also be at risk for vitamin B12 deficiency.

The reason these individuals are more susceptible to vitamin B12 deficiency is because they may not be consuming enough vitamin B12-rich foods, or their bodies may have difficulty absorbing the vitamin from food. This can lead to symptoms such as fatigue, weakness, and neurological problems. It is important for these individuals to monitor their vitamin B12 levels and consider supplementation if necessary to prevent deficiency.
