Nikki Hart | How nutrition feeds mental wellbeing

Season 1, Ep. 29

Nikki Hart is a NZ registered nutritionist and weight management expert. Nikki became well known as “The Evil Diet Witch” when she hosted the TV series ‘Eat Yourself Whole’ and ‘The Fat Chance’.


In this episode, Nikki talks to JK about the connection between good nutritional practices and better mental wellbeing. They discuss the results of the recent ‘Smiles Trial’ study showing the correlation between eating more fruit and lower incidence of depression and other mental wellbeing issues.


Further, Nikki examines a new study by Elaine Rush showing that carotenoids, the pigments which give fruit and vegetables colour, have a greater effect on health outcomes than previously thought, and that a majority of New Zealanders aren’t getting enough of them.


As part of our Groov wellbeing campaign on Winter Wellbeing, Nikki shares tips and tricks for getting enough protection from our nutritional choices in winter, and how to eat well efficiently using seasonal vegetables.


JK and Nikki also discuss “Blue Zones”, countries or regions whose traditional diets provide high balanced nutrition resulting in low incidence of obesity and a host of other related health issues. They talk about what makes up a “Blue Zone” diet and how we can build this kind of culture in New Zealand.

His approach has influenced various teams globally, demonstrating the universal relevance of his strategies.The Essence of Effective Leadership: On leadership, Enoka believes in empowering others: "Great leadership's all about two rules. First, it's not about you. And secondly, it's only about you. This paradox encapsulates the servant leadership model we’ve integrated into the All Blacks." His philosophy underscores the importance of humility and accountability in leadership roles.Cultivating Team Culture: Enoka stresses the critical role of a nurturing team culture in achieving lasting success. "A positive culture enhances performance. It’s about ensuring each member feels they belong and contribute meaningfully to the team’s objectives," he noted. His initiatives have helped create a supportive and unified environment, pivotal in the All Blacks' enduring success.Mental Preparation for Peak Performance: Enoka’s mental conditioning programs are designed to prepare athletes for high-pressure environments. He shared, "Players who are mentally prepared will perform better on the day. Our job is to equip them with tools to handle pressure, not just in rugby but in life." His comprehensive approach has proven effective on the world stage.Reflections on Personal Growth: Enoka's journey is a testament to the impact of personal history on professional methods. Reflecting on his career, "I'd be so much less without what I went through. Those challenges shaped me into the coach I am today." His narrative emphasizes the transformative power of past experiences in shaping future successes."What we've instituted goes beyond rugby; it's about life skills that help individuals thrive in any high-pressure environment." His legacy in the All Blacks and his broader influence on sports psychology underscore his significant contributions to sports and beyond.Take a listen today!
