Answer:
<em>Although this may sound like a healthy way of eating since his diet contains a healthy snack such as fruits, it is not a healthy diet.</em>
Explanation:
A healthy diet consists of many things. As in reference to the food chain, fruits are required for a healthy diet. Though, that is not all. A healthy diet is a mix of fruits, vegetables, protein such as meats, grains, and more.

Answer:
D. provitamin.
Explanation:
A provitamin is a substance that the body can transform into an active vitamin through metabolic processes. If compared with vitamins, provitamins have no biological activity or are much lower. In other words, provitamins are vitamin precursors.
Although not very frequent, sometimes you can see the term previtamin used as a synonym.
For example, beta-carotene, the most abundant carotenoid in nature, has about one sixth of the biological activity of retinol, or vitamin A, but can be transformed into retinol in the liver by an enzymatic reaction.
