It depends on the specific institution, but the US higher educational system does have a lot of very specialized degrees. This is part of a "Food Science & Nutrition" program (https://staging.fshn.illinois.edu/about/what-we-do-why-it-ma...).

While the value of some of these courses is somewhat questionable on their own (hence the old joke about majoring in "Underwater Basket Weaving"), they make a bit more sense as part of a broader program and/or a double-major.

For instance, you might double major in Chemistry, plus Food Science and Nutrition, if you intend to do some work in that industry - or perhaps Business plus Food Science and Nutrition.

Someone with less ambitious college plans might major in Food Science and Nutrition alone and aim for a job as a nutritionist, or a restaurant manager, etc.?

It's also common for people to register for courses like this as a fun or lightweight diversion from "more serious" majors. For instance, MIT offers a course on glassblowing, which counts toward the humanities & arts part of the general curriculum requirements.
