This question has been asked so many times by mostly home-economic students wanting to study nursing in the tertiary.
Below are some of the most valid views you will get on this question.
Chemistry or biology class is probably closer aligned to nursing.
In home economics, cooking, sewing, grocery shopping, and learning to understand nutrient labels – all teach fine-tuned attention to detail and accuracy.
Cooking – recipes with too much of this or that, or leaving out or adding something else might be a disaster – or an improvement.
Sewing – learning to make patterns or adapt a pattern or sew where you are supposed to affects fit, or the end product being what you expect.
Grocery shopping and understanding labels for breakdown can be life or death for a diabetic or someone with Celiac disease or a heart condition ( those relate directly to nursing and caregiving) or helping keep yours or a family member’s weight go up or down.
For shopping supplements, it can be important to not overdose on daily maximums such as zink or selenium. If you get certain ones in multiple products it can be dangerous. Label reading and charting out how much of this or that you get in each on a spreadsheet is really important.
Separately, if you do take supplements, your primary care doc should know what you take as they can interfere with prescribed meds.
The second point to consider
Home Economics in public school education has been known as Family and Consumer Science. Family and Consumer Science teach practical skills related to skills one needs to live on one’s own or in contributing to a family or roommate arrangement. For instance, balancing a checkbook/ monthly bank statements, utilizing microwave and other food sciences, child care, laundry etc. Basics about child care, some basics of nutritional requirements for life, to name a few.
