Jen Belanger – Registered Dietitian(RD)



My name is Jen and I am the owner of my nutrition consulting company, Jen Belanger Nutrition LLC. I am a Registered Dietitian (RD), trained to deliver evidence based nutritional therapy and Medical Nutrition Therapy. I obtained my Master’s degree from UMASS Amherst and am proud to serve there as an adjunct faculty member, teaching students what I love! I have a wide range of nutrition and counseling experience, working with babies as young as 6 months all the way through adulthood. I help families navigate food issues from general healthy eating to food allergies, gastrointestinal conditions, picky eating, and more. The COVID-19 pandemic has resulted in countless concerns around body image and disordered eating, and I tackle these issues head-on with my clients and their families. I am also formally trained in treating ARFID, or “extreme picky eating.”

My team includes another RD and my nutrition intern, and we work hard to bring you the best nutrition resources, recipes, and support that we can. Together, we have over 12 years of experience in nutrition assessment and counseling. Here are just some of the nutrition concerns we see regularly:

  • General healthy eating
  • High cholesterol and/or triglycerides
  • High blood sugar / pre-diabetes
  • Picky eating and extreme picky eating/ARFID
  • Eating disorders
  • GI concerns like IBS, food intolerances, and food allergies
  • Nutrition support (enteral and parenteral nutrition)

We accept most major insurance plans (Aetna, Allways, Blue Cross Blue Shield, Cigna, Harvard Pilgrim, Health New England, Tufts, Tufts Public (in partnership with Boston’s Children’s ACO) Unicare, and United Healthcare).

When I’m not in my office or catching up on work, you can find me at a yoga class, cooking up a storm, or hanging out with my growing family. Raising and feeding my now 17 month-old daughter has made me an even better pediatric dietitian!
