How Diet Can Save Your Mental Health with Professor Felice Jacka #74

Sep 18, 2019 1h 22m 27 insights
We all know that a poor diet negatively impacts our physical health. In fact, it is now the leading cause of early death in men and number two in women. But it’s not only our physical health that is affected – the effects on our mental health can also be devastating. This week, I am joined by world leading expert in the field of nutritional psychiatry, Professor Felice Jacka, to discuss her ground-breaking research into the link between food and our mental health. We discuss why lifestyle medicine should be the starting point for many mental health conditions and why there is an urgent need to train medical practitioners to give such lifestyle advice. We delve into the important role the gut microbiome plays in this area and how a diet rich in diversity is key. We also talk about the link between a mother’s diet in pregnancy and their child’s emotional health. At a time where the modern food environment is so broken and depression and anxiety are on the rise, this conversation is more important than ever. It really is a fascinating listen – I hope you enjoy it!

Actionable Insights

1. Prioritize Lifestyle Medicine

Lifestyle medicine, encompassing diet, exercise, sleep hygiene, smoking cessation, and substance use, should be the fundamental starting point for addressing mental health conditions.

2. Prioritize Simple, Affordable Diet

Recognize that what you eat significantly impacts your mental and brain health, and aim for simple, basic, and affordable whole foods rather than complex or expensive diets.

3. Regular Enjoyable Exercise

Prioritize regular exercise that you enjoy, such as walking or resistance training, as it has flow-on benefits for sleep, mental health, and overall well-being.

4. Eat Plant-Predominant Whole Foods

Aim for a plant-predominant diet with as much diversity of whole foods as possible, while actively avoiding ultra-processed foods, for optimal health.

5. Diversify Your Whole Foods Diet

To improve gut health, aim for a highly diverse diet rich in whole foods, as a more varied diet leads to a more diverse gut microbiome, which is a marker of health.

6. Reduce Junk & Processed Foods

Even if you eat lots of healthy food, consuming junk and processed foods is problematic for mental health, as healthy and unhealthy dietary patterns are independently related to mental health outcomes.

7. Increase Dietary Fiber Intake

Most people do not consume enough dietary fiber, which is essential for gut microbes to function properly, so actively seek to increase your intake from plant foods.

8. Avoid Emulsifiers & Artificial Sugars

For better gut health, avoid emulsifiers and artificial sugars, which are common in processed foods and have been shown in animal studies to negatively impact the gut lining.

9. Consume Polyphenol-Rich Foods

Incorporate foods rich in polyphenols, such as colorful fruits and vegetables, green tea, dark chocolate, and coffee, as they appear to be important for health.

10. Plate Composition for Healthy Meals

For simple healthy eating, aim for half your plate to be vegetables and salads, a quarter whole grains, a quarter good quality protein, and finish with healthy oil like olive oil.

11. Reduce Refined Carbs

Focus on cutting down on refined and processed carbohydrates rather than broadly demonizing all carbohydrates, as this distinction is crucial for a healthy diet.

12. Apply 80-20 Rule to Diet

Strive for an 80-20 rule in your food choices, where 80% are healthy, as this approach is realistic and significantly better than average, avoiding the mental health burden of striving for dietary perfection.

13. Healthy Eating Is Affordable

Eating a healthy diet, as demonstrated in the SMILES trial, can be significantly cheaper than an unhealthy diet, dispelling the myth that healthy food is inherently expensive.

14. Address Insulin Resistance Holistically

To improve insulin sensitivity, increase muscle mass, improve sleep, and manage stress levels, and as sensitivity improves, gradually reintroduce fiber-rich, nourishing carbohydrates like sweet potatoes.

15. Consult Nutrition Professionals

For better outcomes with dietary interventions, consult a clinical dietitian or nutrition professional who can provide expert guidance on both what to eat and how to achieve dietary changes.

16. Clinician Prioritization of Lifestyle

When clinicians prioritize discussions about nutrition and lifestyle changes in consultations, patients are more likely to prioritize and act upon those recommendations.

17. Support Healthy Lifestyles in Mental Illness

For individuals with serious mental illnesses, supporting healthy lifestyle behaviors like diet and exercise can mitigate the noxious impact on their metabolic health and improve overall outcomes.

18. Holistic Lifestyle Approach for Mental Health

Taking a lifestyle medicine approach to mental health problems, such as depression or schizophrenia, targets the whole person, leading to huge benefits across the board rather than just specific pathways.

19. Wear Minimalist Shoes

Minimalist shoes, which are thin, wide, and flexible, can be beneficial for musculoskeletal health, improving balance, stability, and reducing various complaints like back, hip, and knee pain.

20. Exercise for Jet Lag

When experiencing jet lag, engaging in exercise like a run can help you feel fresher and mitigate the effects of sleep deprivation.

21. Red Meat for Menstruating Women

For menstruating women, consuming a small amount of unprocessed red meat (3-4 palm-sized servings per week) may be beneficial, based on some observational findings.

22. Improve Highly Processed Diet

If you consume a highly processed Western diet, almost any change you make towards healthier eating patterns is likely to result in significant health improvements.

23. Short-Term Low FODMAP, Reintroduce Gradually

If using a low FODMAP diet, ensure it is a short-term solution, and then gradually reintroduce FODMAP foods, ideally alongside fermented foods and/or probiotics, to help gut bacteria adapt.

24. Advocate for Healthy Food Environments

Support and advocate for changes in the food environment at policy and legislative levels to make healthful food choices easier and more accessible for everyone.

25. Empower & Support Healthy Choices

While empowering individuals to make healthful food choices, it’s crucial to also advocate for environmental changes that make healthy eating the easier option, rather than solely blaming individual choices.

26. Be Architect of Your Health

Recognize that you are the architect of your own health and that making lifestyle changes is always worthwhile, as feeling better directly leads to living a more fulfilling life.
