Which of the following is commonly deficient in a vegetarian diet?

A vegetarian diet can sometimes be low in certain nutrients that are predominantly found in animal products. Calcium is one of those nutrients, as it is typically abundant in dairy products such as milk, cheese, and yogurt. Individuals following a strict vegetarian or vegan diet may not consume enough calcium-rich foods, leading to a potential deficiency.

Calcium is essential for maintaining strong bones and teeth, as well as for muscle function and nerve signaling. Many plant-based sources of calcium, such as dark leafy greens and fortified plant milks, may not provide sufficient amounts of this mineral compared to dairy products. This can particularly impact individuals who do not carefully plan their diets to include alternative sources of calcium.

While Vitamin C is abundant in fruits and vegetables, sodium is generally easily obtained from many food sources, and total fat intake can vary widely based on the choice of plant-based foods. Thus, calcium stands out as a nutrient that may require careful attention in a vegetarian diet to ensure adequate intake.
