A very pleasant person to talk to about my poor personal eating habits with no stress. Totally understanding food choices being a stressor for me, Sarah has helped me to overcome this stress I have with food. I wish I called sooner, however the stress of talking about food has a way of stressing me out. I thank Sarah for her encouragement to help me take on my challenge to change my eating habits, losing weight, and regaining my health.

Disclosures

Sarah J. Buytendorp, RD reported no external professional relationships for calendar year 2025.

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care. These relationships are important in achieving scientific breakthroughs and in establishing the effectiveness and safety of promising new therapies. In order to assure objectivity in clinical research and patient care, the Northwestern University Feinberg School of Medicine (Feinberg), Northwestern Memorial HealthCare, Children's Hospital of Chicago Medical Center, and the Shirley Ryan AbilityLab have adopted integrity policies that require research and clinical faculty (in full-time, part-time, and unpaid/voluntary categories) to report compensated and uncompensated external industry relationships. Patients are encouraged to discuss these disclosures with their physician as well as to inquire as to how these relationships are overseen by Feinberg. To learn more about our Disclosure and Professional Integrity Policy, and the conflict of interest policies of our joint affiliate survey partners, please go to our Office for Regulatory Affairs Policies page.
