Answer:
False.
Step-by-step explanation:
The term nutrient bioavailability refers to how much we will absorb and utilize the nutrients available in food. This varies according to the interactions this nutrient will undergo, with substances (such as medicines) and even with other nutrients. These interactions can increase or decrease the bioavailability of nutrients. In the case of a vitamin D fortified orange juice, the bioavailability of vitamin D is increased rather than decreased as the juice is providing more vitamin D to the body. In this case, the bioavailability of vitamin D will only be diminished if any other element present in the body is causing an imbalance.
