Frequently Asked Questions
Do I need a degree to take a short nutrition course in NYC?
No — most short and certificate-level programmes in this guide are open to people without specific prior qualifications. eCornell’s Nutrition and Healthy Living Certificate, the NYC continuing-education certificate via ed2go, and the Plant-Based Nutrition Certificate all have open or minimal entry requirements. The exceptions are NYU’s Advanced Certificate in Public Health Nutrition, which is a graduate-level programme requiring a relevant bachelor’s degree and NYU admissions approval, and Columbia’s short IHN offerings, which are primarily aimed at healthcare professionals and graduates.
Can I take these nutrition courses fully online from New York City?
Three of the five options in this guide are fully online and accessible from anywhere: eCornell’s certificate, the ed2go NYC continuing-education certificate, and the Plant-Based Nutrition Certificate. NYU’s Advanced Certificate is based at the NYU School of Global Public Health in New York City and may include campus or in-person elements, though coursework is typically structured to accommodate part-time study. Columbia’s Institute of Human Nutrition short programmes are generally delivered in person at the Columbia University Irving Medical Center campus in NYC.
Will a short nutrition certificate help my career?
It depends on your field and goals. A Cornell-branded or NYU certificate can strengthen a professional profile in wellness, coaching, content creation or allied health, and carries more weight with employers and clients than a generic online course. For regulated roles — such as registered dietitian in New York State — short certificates do not substitute for an accredited academic programme, supervised practice and licensing exams. If you’re a health coach, personal trainer or content creator, a recognised certificate can sharpen your positioning; if you’re a clinician, deeper study or formal accreditation may be needed alongside.
How long do short nutrition certificates typically take to complete?
Completion times vary across this shortlist. The ed2go NYC continuing-education certificate can typically be finished in a few weeks. eCornell’s Nutrition and Healthy Living Certificate and the Plant-Based Nutrition Certificate both take a few months of part-time study. NYU’s Advanced Certificate takes around a year part-time. Columbia’s short intensive programmes are designed to be completed in days to weeks depending on the specific format. All five options can be fitted around full-time work, though the time commitment and structure differ substantially.
What’s the difference between a nutritionist and a registered dietitian in New York?
In New York State, the title “dietitian-nutritionist” is legally protected under state law. To use it professionally, you need to be licensed as a Certified Dietitian-Nutritionist (CDN), which requires completing an accredited degree programme, supervised practice, and passing the national registration examination. Short certificate courses — including all the options in this guide — do not fulfil these requirements and do not qualify you to practise as a licensed dietitian in New York. If your goal is licensure, you’ll need an accredited degree pathway. If you want practical nutrition knowledge for coaching, personal use or content creation, a short certificate is a worthwhile and credible option.
How to Choose
The right programme depends on your background, goals and how much time you can commit. Here’s how the five options break down.
If you prioritise
Academic Credibility
Go with eCornell’s Nutrition and Healthy Living Certificate — a Cornell-issued credential you can complete fully online around work, covering nutrition science broadly and practically without enrolling in a degree.
If you prioritise
Public Health or Clinical Depth
NYU’s Advanced Certificate is the strongest option for nutrition in public health practice and policy. For clinical, evidence-based depth in an NYC medical setting, Columbia’s Institute of Human Nutrition is the better fit. Both require prior qualifications.
If you prioritise
Accessibility or a Specialist Niche
The ed2go NYC certificate is the lowest-barrier entry point for complete beginners. If your focus is specifically plant-based nutrition — for coaching, fitness or content creation — the T. Colin Campbell Center certificate is the more focused and widely recognised option.
