Hashimoto’s & Autoimmune Disease Nutrition in Portland, OR

Your diagnosis is only the beginning of the story. Let's look at what your immune system needs to feel supported.

Chelsie Moore is a functional medicine clinician and integrative dietitian nutritionist in Portland, OR, who helps women with Hashimoto's thyroiditis and other autoimmune conditions. She uses personalized, root-cause nutrition to support energy, inflammation, gut health and quality of life. She sees clients in person in Portland and virtually.

Maybe you were handed a prescription and told to come back in six months. Or maybe your thyroid numbers look fine, but you still feel exhausted, foggy and inflamed. There's more to explore, and nutrition is one of the most powerful places to start.

Does This Sound Familiar?

Living with Hashimoto's or another autoimmune condition can feel like managing a moving target. You might be experiencing:

• Fatigue that doesn't match how much you're sleeping

• Brain fog, forgetfulness or trouble concentrating

• Weight changes that don't respond to what used to work

• Feeling cold, puffy or sluggish

• Joint aches, stiffness or unexplained inflammation

• Bloating, constipation or other digestive issues

• Hair thinning, dry skin or brittle nails

• Low mood or anxiety

• Flares that seem to come out of nowhere

• Confusion about what to eat, after reading ten different "autoimmune diets" online

You're not being dramatic, and you're not doing it wrong. Autoimmune conditions are complex, and you deserve a plan that treats you as a whole person rather than a lab value.

What Is Hashimoto's, and What Is Autoimmune Disease?

Autoimmune disease happens when the immune system mistakenly targets the body's own tissues. There are many autoimmune conditions, and women are affected far more often than men.

Hashimoto's thyroiditis is an autoimmune condition in which the immune system attacks the thyroid gland. Over time, this can reduce thyroid hormone production. Hashimoto's is the most common cause of hypothyroidism in the United States. It's usually identified by elevated thyroid antibodies (TPO or thyroglobulin antibodies) along with thyroid hormone labs.

Thyroid medication replaces missing hormone, and for many people it's essential. But it doesn't address the immune activity behind the condition. That's where nutrition and lifestyle come in. What you eat, how well you digest and absorb nutrients, your stress load, and your sleep can all influence inflammation, energy and how you feel day to day.

A Root-Cause Nutrition Approach to Autoimmunity

There's no single "autoimmune diet" that works for everyone, and overly restrictive plans can backfire. My approach is personalized, evidence-informed, and built to be sustainable. We look at:

• Nutrient status: key nutrients for thyroid and immune health, including selenium, iodine, zinc, iron, vitamin D and B12, with a focus on getting enough without going overboard

• Gut health: digestion, absorption and the gut–immune connection

• Food sensitivities and triggers: thoughtful, time-limited elimination and reintroduction when it's warranted, never restriction for its own sake. Gluten gets special attention, since celiac disease is more common in people with Hashimoto's

• Inflammation and blood sugar: anti-inflammatory eating patterns and steady blood sugar to support energy

• Stress, sleep and hormones: how cortisol and life stages like postpartum and perimenopause interact with autoimmunity

• Medication and meal timing: practical guidance so food, coffee and supplements don't interfere with thyroid medication absorption

Your plan may include personalized nutrition, targeted lab testing, realistic behavior-change strategies, and pharmaceutical-grade, third-party tested supplements from one of our trusted partners. I work alongside your endocrinologist, primary care provider or rheumatologist, not in place of them.

Meet Chelsie Moore

I'm Chelsie Moore, a functional medicine clinician and integrative dietitian nutritionist, and the founder of Moore Integrative Health in Portland, Oregon. I work primarily with women on autoimmune concerns, hormone health, perimenopause, fatigue, mood and sleep, and blood sugar regulation.

I hold a master's degree, two years of clinical residency, a certification in behavior change from the Yale School of Public Health, and I'm in on-going continuing education with Aviva Romm, MD with a pending certification in Integrative & Functional Women's Health. That behavior-change background shapes everything I do. A plan is only useful if it fits your real life, so we build one you can actually follow.

You deserve care that takes your symptoms seriously and helps you feel more like yourself.

Hashimoto's & Autoimmune Nutrition FAQs

What is the best diet for Hashimoto's?

There's no single best diet for everyone with Hashimoto's. A nutrient-dense, anti-inflammatory eating pattern that supports steady blood sugar and adequate protein is a strong foundation. From there, the right plan depends on your symptoms, labs, digestion and possible food sensitivities.

Should I go gluten-free if I have Hashimoto's?

It depends. Celiac disease is more common in people with Hashimoto's, so it's worth being screened, ideally before you remove gluten. Some people without celiac also feel better gluten-free, but it isn't necessary for everyone. We can decide together based on your testing and how your body responds.

Can nutrition help with autoimmune disease?

Nutrition can't replace medical treatment, but it can meaningfully support energy, digestion, inflammation and overall well-being. It can also correct nutrient deficiencies that are common in autoimmune conditions.

Do I still need thyroid medication if I change my diet?

That's a decision for you and your prescribing provider. Nutrition works alongside medication. Never stop or change a prescription without talking to your doctor.

What's the difference between a dietitian and a functional medicine practitioner for autoimmune disease?

A dietitian specializes in evidence-based nutrition. A functional medicine approach looks at the root-cause connections between systems, like gut health, stress and hormones. As an integrative dietitian nutritionist with functional medicine training, I combine both.

Do you offer virtual appointments?

Yes. I see clients in person in Portland, Oregon, and virtually.

Do you take insurance?

Moore Integrative Health is an out-of-network provider. I can provide a superbill you may submit for possible reimbursement, and HSA/FSA funds can often be used.
