Which statement regarding vitamin needs is true for males and females ages 19-30?

The choice indicating that vitamin E needs are the same for both males and females ages 19-30 is accurate because the dietary reference intakes (DRIs) set by nutritional guidelines recognize that both genders have the same requirement for vitamin E in this age group. This means that regardless of gender, the amount of vitamin E needed to achieve adequate health benefits and prevent deficiencies is consistent for both males and females.

It's important to note that while some vitamins have different recommendations based on gender, vitamin E is not one of them in this particular age range. This standardization reflects the understanding that vitamin E functions similarly in the body regardless of sex, contributing to immune function and acting as an antioxidant.

In contrast, other vitamins, such as vitamin C and folate, may have different needs based on gender, reflecting various physiological factors, including differences in metabolism, hormonal influences, or reproductive health. For example, vitamin C requirements could be higher for males due to larger body mass or differences in lifestyle factors, while folate needs may vary due to biological functions specifically associated with females.
