Janet Zarowitz, RD
A graduate of Cornell and Columbia Universities, Janet is an integrative and functional nutritionist who looks for the root causes of poor health and not just symptom management. She believes that a blend of whole food therapy (Food as Medicine), targeted nutrition supplements, and healthy lifestyle changes form the basis of wellness and good health and feeling better. Clients see her of variety of nutrition-related concerns, such as poor digestion, food intolerances, anxiety and mood disorders, candida and restoring gut balance, immunity and autoimmune disorders, fatigue, post cancer therapy to name a few. She has worked extensively with paleo, gluten-free and GAPS protocols. In addition, Janet has experience with Nutrigenomics - personalized nutrition to support health based on the clues of your unique genetic profile. Janet focuses on genes in the methylation pathway that play a role in your immunity and gene expression, detoxification and antioxidant generation. These genes, responsible for the production of methyl groups, also regulate neurotransmitter production, nerve health, and your ability to utilize the folic acid required for cell reproduction and replenishment. Janet offers nutritional assessments, nutrition care plans, nutrition supplement consultations and ongoing nutrition coaching. She takes a practical approach with short and long-term dietary modifications that are sustainable.
