Here is an interesting resource to consider. Nebraska is top 30 but IA State interestingly is top 3. In fact, IA State keeps popping up in other rankings of nutrition science programs on the internet. It’s clearly a well-regarded program. This has to be taken into account because it’s more than just affordability, it’s reputation. The ROI figures will apply directly to OP as an in-state resident of IA. (NDSU and UMTC #'s 1 and 2, respectively; UMTC is ramping up OOS tuition over the next few years so might well have the same financial challenges as OP would face at UW-Madison. NDSU might be a bit more affordable - not sure. OP would need to explore scholarships for both).

My D16 is attending a private art college 1,300 miles away from our home. There are 3 other kids in her high school who started with her - we thought there were only two; however, she bumped into the third just recently! (and yes she’s seen the other ones too. And she’s made new friends and not hanging out with any of the old ones). So not only do you NOT have to hang out with your old high school classmates when in college, you don’t necessarily avoid them by moving away!
