Reference excerpt

Megan Rossi (born 10 October 1988) is a dietitian, nutritionist and author specialising in the microbiome. Her PhD in gut health received the Dean's Award top 5% for Outstanding Research Higher Degree. Rossi founded the website The Gut Health Doctor, including The Gut Health Clinic.

She is an advocate and researcher of plant-based nutrition.

Early life and education One of three children, Rossi was raised by her single mother, a science teacher, on a farm near Cairns in rural Australia. Rossi studied Dietetics at Queensland University of Technology from 2006 to 2009. After receiving first-class honours, she went on to conduct more research into the field while working as a dietitian at Princess Alexandra Hospital, Brisbane. In 2014, she earned her PhD in gut health from the University of Queensland while also working as a nutritionist for the Australia Olympic Synchronised Swimming team. Rossi moved to London, UK in 2015, where she lives with her husband Thomas and her sons Archie and Cooper.

She has published over 50 scientific papers in International peer-reviewed journals.

The Gut Health Doctor In 2017, Rossi established an online presence as The Gut Health Doctor (@theguthealthdoctor with over 600,000 followers across various social media platforms), with a focus on linking gut health with other health concerns such as mental health, heart disease, kidney disease and skin conditions.

Plant-based nutrition Rossi has noted that there are a number of different plant-based diets including veganism, lacto-vegetarianism, lacto-ovo vegetarianism, pescetarianism and flexitarianism. She has stated that a plant-based diet does not have to be vegan and can occasionally include meat but the bulk of the diet must be built around plant foods. Rossi has commented that she does not personally promote a vegan or vegetarian diet. Her advice is to eat more plants but not eliminate entire food groups. According to Rossi, "including some animal foods in your diet can be a valuable way to decrease your risk of nutritional deficiencies - I am in no way antimeat". She has criticized plant-based junk and processed foods, including vegan cheese for degraded nutrients. Rossi has argued that a plant-based diet is the opposite of a fad diet, it is a sustainable way to eat a healthy diet. She has stated that the main focus of a plant-based diet should be on whole foods, including whole grains, fruit, vegetables, legumes, nuts and seeds. Rossi has suggested that gut health is about moderation and plant diversity and that the ultimate goal should be to eat 30 different types of plant-based foods every week. She says that the 5 A Day rule is a good starting point but the microbes living in the gut need a diversity of plants to flourish.

Eat Yourself Healthy (Love Your Gut) Rossi's debut book, Eat Yourself Healthy (UK, Australia & Europe) and Love Your Gut (US & Canada), was published in September 2019. The book features recipes and advice on IBS and bloating, diagnosing food intolerances, and the relationship between gut health, sleep and exercise. The book was dedicated to her older sister, Justine, who died aged 5 in a playground accident. It was a Sunday Times bestseller and has been published in 4 languages to date.

Eat More, Live Well Rossi's book Eat More, Live Well was published in 2021 by Penguin Books and was also a Sunday Times bestseller. The book suggests eating 30 different plant-based foods a week. The editors of the book commented that "based on the latest gut-health science, all of the recipes are packed with plants, but you’ll still find meat, dairy and eggs in there, because it’s all about diversity—eating more, not less. Megan’s love of food shines through every page and we can’t wait to see people enjoying her tasty creations".

Worked examples

Example 1 — a first encounter with Megan Rossi

Start with the simplest possible case. Write down what Megan Rossi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Megan Rossi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Megan Rossi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Megan Rossi

In research: Megan Rossi appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Megan Rossi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Megan Rossi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1988 births, British health and wellness writers, British medical writers, so understanding it makes those chapters shorter.
In everyday life: Look for Megan Rossi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
