Nah. Most "nutritionists" are clowns. Anyone can call themselves a nutritionist with no formal training or certification. The whole field is mostly filled with frauds and grifters.

There are some legitimate people with a Registered Dietician credential who can work as part of a care team to treat medical conditions. But most of us don't need them either. We know what we're supposed to eat, we just don't do it.

Exactly. No point in playing someone to tell me to eat more leafy greens.
