Dr Terry Wahls, Multiple Sclerosis, and the Power of Nutrition

Dr Terry Wahls is a clinical professor of medicine who was diagnosed with secondary progressive multiple sclerosis (MS). After seven years of conventional treatment failed to halt her decline, she turned to nutritional research and designed a diet aimed at restoring her mitochondrial function. The results were remarkable enough to inspire a viral TEDx talk, a clinical research programme, and a global community of people managing MS through food.

This article covers who Dr Wahls is, what the Wahls Protocol involves, why mitochondria are central to her approach, and where green tea fits into an anti-inflammatory lifestyle.

At a glance

Who is Dr Terry Wahls?

Terry Wahls MD is a clinical professor of medicine at the University of Iowa. She was diagnosed with relapsing-remitting MS in 2000, which progressed to the secondary progressive form despite treatment with chemotherapy and immunosuppressive drugs. By 2003, she was using a tilt-recline wheelchair and could no longer hold her torso upright unaided.

Rather than accept further decline, Dr Wahls began reviewing the scientific literature on mitochondrial function, neurodegenerative disease, and nutritional biochemistry. She designed a personalised dietary protocol based on that research and applied it to herself. Within months she had regained significant function. Within a year she completed an 18-mile bike ride.

Her story is not presented as a cure for MS, and she is careful to frame her work as a hypothesis supported by personal experience and emerging clinical research rather than established medical consensus. She continues to run clinical trials exploring dietary interventions for MS at the University of Iowa.

The “Minding Your Mitochondria” TEDx talk

Dr Wahls first presented her story publicly in a TEDx talk titled “Minding Your Mitochondria” in 2011. The talk has since accumulated millions of views and thousands of comments from people with MS and other autoimmune conditions who report that adopting a similar protocol improved their symptoms.

The title of the talk reflects the central idea: that mitochondrial dysfunction may be an early driver of chronic disease, and that nutrient-dense food can support mitochondrial health in ways that pharmaceutical intervention alone cannot.

Whisk a bowl of matcha, sit back, and watch Dr Wahls’ TEDx talk on how diet reshaped her MS journey:

What are mitochondria, and why do they matter?

Mitochondria are organelles found in almost every cell in the body. Their primary job is to convert nutrients from food into ATP (adenosine triphosphate), the chemical energy currency cells use to function. They are sometimes called the powerhouses of the cell.

In Dr Wahls’ framework, when mitochondria are starved of the raw materials they need, cellular energy production falters. This creates a cascade of effects: cells underperform, tissues deteriorate, and organs begin to dysfunction. She argues that this process underlies many chronic diseases, including neurodegeneration.

The good news, in her view, is that mitochondria are responsive to nutritional input. By supplying the right nutrients in sufficient quantities, it may be possible to restore function at the cellular level.

What is the Wahls Protocol?

The Wahls Protocol is a structured nutritional approach developed by Dr Wahls based on her own recovery and her review of the scientific literature. It is a modified version of a Palaeolithic-style diet, meaning it emphasises whole foods that would have been available to pre-agricultural humans and excludes grains, legumes, dairy, and processed foods.

Core principles

Large quantities of vegetables and fruit Dr Wahls recommends nine cups of vegetables and fruit per day, divided across three categories:

• Leafy greens (kale, collard greens, spinach, Swiss chard) for fat-soluble vitamins including K, A, B vitamins, and minerals
• Deeply coloured vegetables and fruit (beetroot, capsicum, berries, red cabbage) for antioxidants and polyphenols
• Sulphur-rich vegetables (onion, garlic, cabbage, broccoli, leek, mushrooms) for detoxification support and mitochondrial health

Quality protein Meat, fish (particularly oily fish rich in omega-3 fatty acids), and organ meats are all part of the protocol. Dr Wahls pays particular attention to organ meats such as liver for their dense micronutrient content.

Healthy fats Omega-3 fatty acids from fish and plant sources are prioritised. Omega-6-heavy processed vegetable oils are excluded.

Elimination of inflammatory foods Gluten, dairy, eggs, and processed foods are removed, particularly in the more advanced versions of the protocol.

What the research says

Dr Wahls has published peer-reviewed research and conducted clinical trials examining the effects of her dietary approach on MS fatigue and quality of life. Results to date have been promising in preliminary studies, though large-scale randomised controlled trials are still limited. The broader scientific community regards the work as an interesting hypothesis that warrants rigorous further investigation.

Green tea, matcha, and multiple sclerosis

One of the most-searched questions that brings people to this article is the relationship between green tea and multiple sclerosis. Here is what the current research suggests.

EGCG and neuroprotection

Epigallocatechin gallate (EGCG) is the primary catechin (a type of polyphenol) in green tea and matcha. A number of laboratory and animal studies have investigated EGCG’s potential neuroprotective and anti-inflammatory properties. Some research has suggested EGCG may inhibit certain inflammatory pathways and support neuronal health.

It is important to note that most of this research has been conducted in cell cultures or animal models. Human clinical trials are limited, and no regulatory body currently endorses green tea or matcha as a treatment for MS. This is an area of active research, not settled science.

Why matcha is particularly relevant

Matcha differs from steeped green tea because you consume the whole leaf in powdered form rather than an infusion. This means you receive a significantly higher concentration of EGCG, L-theanine, chlorophyll, and other polyphenols per serving.

L-theanine is an amino acid found almost exclusively in tea. It has been studied for its calming, focus-supporting effects and its ability to moderate the stimulant effect of caffeine without dulling alertness.

For anyone following an anti-inflammatory dietary approach such as the Wahls Protocol, matcha offers a convenient, pleasurable way to add polyphenol-rich food to the daily routine.

Matcha and the Wahls Protocol

Matcha sits comfortably within the nutritional philosophy of the Wahls Protocol. It is a whole-leaf green food delivering concentrated plant polyphenols, no processed ingredients, no gluten, no dairy, and no artificial additives. Made simply with water, it aligns with the protocol’s emphasis on clean, nutrient-dense inputs.

How to get started with matcha

You do not need elaborate equipment. The essentials are quality powder, hot (not boiling) water, and a way to mix them smoothly.

A bamboo whisk (chasen) makes a noticeable difference to texture and froth. See the matcha whisk buyers guide for help choosing one.
