The correct approach to ensuring adequate vitamin D intake is through a combination of sunlight exposure and the consumption of fortified foods. Vitamin D is unique among vitamins because the body can produce it when the skin is exposed to sunlight, specifically UVB radiation. This natural production is a vital source of vitamin D for many individuals.

In addition to sunlight, many foods are fortified with vitamin D, such as milk, certain cereals, and plant-based dairy alternatives, which help provide this important nutrient, especially for those who may not get sufficient sunlight due to geographical location, lifestyle, or other health considerations.

When considering the other options, consuming high amounts of carbohydrates does not contribute to vitamin D levels, and limiting sun exposure directly reduces the body's ability to synthesize vitamin D. Furthermore, while avoiding all animal products may impact some people's vitamin D intake, it is not a reliable means to ensure adequate vitamin D levels, especially since some food sources rich in vitamin D, like fatty fish and eggs, are animal-based. Hence, a combination of sunlight exposure and consumption of fortified foods is the most effective strategy for maintaining sufficient vitamin D levels.
