The digestive system does not have as one of its functions the need for nutrients, apart form them needed to keep it healthy and functioning. It is more appropriate to ask, what nutrients do the cells of the body need? And how can the digestive system function optimally in order to accomplish that goal?
The purpose of the digestive system is to break down foods in order to supply nourishment to the cells of the body. So, ultimately, it is what we choose to ingest that will provide the nutrients that our body needs. The digestive system is just an avenue for good nutrition to be supplied to the body.
So, to answer your question more technically: All nutrients are involved in the digestive system because that is how the nutrients gain access to all the cells in the body.

Why dont most parasitic flatworms need a complex digestive system?
Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.

Where do nutrients from the digestive system go?
Nutrients from the digestive system enter the circulatory system. From there, they are transported to all body cells.
How do tapeworms feed if they have no digestive systems?
Tapeworms are parasitic; they don't have need a digestive system because they absorb the nutrients they need from their host(s).
How does the digestive system help you?
The digestive system separates the nutrients that your body needs from what it doesn't need, and then the not needed stuff becomes solid and liquid waste.
In digestive system Where are all the most nutrients observed?
Nutrients are found throughout the digestive system. Most nutrients are absorbed in the small intestine.
The circulatory system works with what other system to get nutrients to all body parts?
The circulatory system works with digestive system to circulate the nutrients to all the body parts. The nutrients are digested and absorbed by the digestive system. The circulatory system circulates the nutrients throughout the body.
Blood picks up what from the digestive system and take it to the cell?
The circulatory system picks up nutrients from the digestive system and takes them to the cells. Absorption is the process of moving the nutrients from the digestive system to the circulatory system.
