Dr. Nourit Houminer-Klepar has deep experience in personalised nutrition based on testing: nutritional status, microbiome and food sensitivities — and in recent years, cellular ageing and the link between nutrition and mental health. More than 20 years of clinical experience, alongside current research in these fields.
Each talk stands on its own, draws on current research — and at times on subjects Nourit has researched herself — and can be adapted to the length, format, audience and language of the host organisation.
From professional debate to TikTok headline
What really lies behind trendy diets? An engaging talk that teaches you to tell scientific fact from online myth. We take apart the common claims about gluten, keto, veganism and oils, and leave with a practical toolkit for weighing nutrition advice independently and on solid evidence.
Before you open another bottle
Whether it’s vitamins, anti-ageing, anti-inflammatory supplements or support for the immune system and gut — how do you know what your body really needs? In this talk we cover:
The science behind slowing the ageing process
What sets the pace at which our bodies really age, and how do we measure it? In this in-depth talk, based on a review of the research frontier, we unpack the molecular and epigenetic mechanisms that define biological age. We look at how dietary patterns, evidence-based diets, specific supplements and lifestyle changes affect key cellular pathways — from silent inflammation and mitochondrial function to gene expression — with the aim of supporting healthy longevity.
The science linking nutrition and mood
How does the food we eat affect symptoms of depression, anxiety and stress? In this in-depth talk we dive into the biological and physiological mechanisms that link nutrition and mental health. The talk presents current research on how specific dietary patterns affect anxiety and depression, alongside a practical review of nutrients, supplements, and interactions between nutrition, supplements and psychiatric medication.
A hands-on workshop for teenagers and their mothers: healthy food choices, body image, and how social media shapes eating and the way we see our looks — no diets, no guilt, and in their own language.
Nourit is a clinical dietitian, researcher and academic lecturer in the Departments of Nutrition and Nursing at Ashkelon Academic College. Her doctorate examined the link between social interactions, stress and cellular ageing.
An American-Israeli researcher and a native speaker of both Hebrew and English, she lectures in both languages to organisations and international teams.
Her research has been published in peer-reviewed journals including Foods, Nutrients, BMC Pregnancy and Childbirth and Biological Research for Nursing, and covers the effects of lifestyle and stress on ageing at the level of the cell, the link between nutrition, mood and mental health, and eating behaviour under stress.
In February 2026 she was named to the Ministry of Innovation, Science and Technology’s “Women in Science” list, for a controlled clinical trial she is leading that tests whether personalised dietary adjustment affects symptoms of depression and anxiety.
In her clinic she has built deep experience in personalised nutrition based on diagnostics: nutritional status, microbiome and food sensitivities.
Every talk is tailored in advance to the goals, language and timing of the host organisation.
Wellbeing sessions that reduce burnout, sharpen focus and energy, and lift offsites and internal conferences — in Hebrew or English.
Nutrition as a support in recovery and regulation. Grounded in her research on emotional eating and wartime stress in an Israeli population.
Compelling, credible content for conferences, seminars and company events — a speaker with an academic record who can hold a room.
Workshops for students and parents on nutrition, body image and social media in adolescence.
