Generally, ordinary hotels don't need nutritionists, because the profits of ordinary hotels have little to do with nutrition, and the basic nutrition collocation and menu preparation are within the scope of the hotel chef's work. Large star-rated hotels or high-end fitness clubs are slightly more likely to need nutritionists. The demand for nutritionists in high-end nursing homes or nursing centers, rehabilitation medical centers or military sanatoriums is rigid. Companies that need nutritionists now generally have strict requirements on the collocation of nutritious meals, and they need real nutritionists to work on the spot, not relying on them. I hope this helps.
