In this episode, we uncover the hidden dangers in our environment, and their profound impact on children’s brain development. While the effects of toxins may seem subtle in individual cases, the damage at the population level is anything but.We explore the scientific challenges of studying these exposures, from identifying critical windows of vulnerability to linking pollutants with intellectual and behavioral outcomes. Despite mounting evidence connecting toxins to ADHD, autism, and other mental disorders, public health protections remain alarmingly inadequate.Tune in as we break down the research, and spotlight the risks.

Can your personality determine what ends up being part of your diet?

In this episode of The Brain Plate, we dive into a systematic review published in Advances in Nutrition that analyzed 24 studies across different cultures to explore how personality traits like neuroticism, openness, and conscientiousness influence dietary habits.

From the Mediterranean preferences of extroverts to the sweet tooth of the neurotic type, the findings are as fascinating as they are revealing. However, we don’t stop at the surface, this episode also takes a very critical look at the article’s methodology and assumptions. What biases are there in the research design? Are certain cultural or psychological nuances being overlooked?

Join us as we discuss the science, question the setup, and raise awareness about how psychology intersects with nutrition, and why quality research matters.

Whether you're a psychologist, nutritionist, or just curious about why you crave what you crave, this episode serves up insight with a side of skepticism.

Join us as we dive deep into the fascinating world of creatine supplementation and its surprising effects on brain function, mental health, and cognitive performance. While generally people know creatine can help you lift heavier weights, the latest science reveals it might also help you think clearer, recover from brain injuries faster, and even support mental health.

We break down a comprehensive 2022 research review that analyzed dozens of studies on creatine's brain benefits. Learn why creatine works best when your brain is under stress. We explore promising research on creatine as a potential add-on treatment for depression, especially in women.

We also take some time to talk about how creatine supplementation could help reduce hospital stays and improve recovery after concussions and traumatic brain injuries, as well as why your brain responds differently to creatine than your muscles (and what that means for you).

Bottom Line: Creatine isn't just about bigger biceps – it might be your brain's new best friend. Tune in to discover if this affordable, well-researched supplement could give your mind the boost it's been looking for.

Are you a morning person or a night owl?

Your natural sleep-wake preferences could reveal surprising insights about your personality and likelihood to engage in risky behaviors.We explore research connecting chronotype to the Big Five personality traits.

Morning people are more conscientious and emotionally stable, while night owls show higher impulsivity and sensation-seeking. Most intriguingly, evening chronotypes demonstrate significantly higher disinhibition, a trait linked to risky decision-making and criminal behavior.

What you will learn:

* How chronotype shapes personality profiles

* Gender differences in these relationships

* Future applications in criminal justice and rehabilitation

Key Findings:

* Morning-types: higher conscientiousness, emotional stability, extraversion

* Evening-types: elevated disinhibition, reduced conscientiousness

* Men show higher thrill-seeking regardless of chronotype

Whether you're interested in psychology, criminal justice, or simply curious about what your sleep preferences reveal about you, this episode uncovers fascinating connections between our biological clocks and behavior.

Can polyphenols—found in berries, teas, and dark chocolate—actually enhance brain function? A new clinical trial from Nutrients (Feb 2025) by Carrillo et al. investigates whether a polyphenol-rich supplement improves cognition and boosts key brain biomarkers (BDNF and CREB) in healthy adults.In this episode, we break down the study’s design (92 participants, crossover trial), the cognitive tests they used, and the eye-opening results: better attention, higher cognitive scores, and increased neuroprotective proteins.What does this mean for brain health and prevention? Should you rely on supplements or stick to whole foods? We discuss the implications and share our take.Tune in now for science-packed insights that could shape your cognitive future!Reference: Carrillo, J.Á.; Arcusa, R.; Xandri-Martínez, R.; Cerdá, B.; Zafrilla, P.; Marhuenda, J.

Prepare for a fascinating blend of courtroom drama and scientific inquiry as we explore the infamous "Twinkie defense" from the 1979 trial of Dan White. What seemed like an unusual legal strategy referencing sugary snacks raises profound questions about the connection between diet, mental health, and behavior.In this episode, we talk about the controversial case that argued poor nutrition, including a diet high in processed junk foods, could influence mental state and decision-making. While the defense helped reduce White's sentence, it sparked public outrage and ethical debates about accountability, personal responsibility, and the role of external factors in shaping behavior.Using this case, we delve into how diet could affect brain function, mood, and even actions. Is there truth to the idea that what we eat can profoundly shape our mental health, or was the "Twinkie defense" a stretch?

In this episode, we explore three distinct approaches to our relationship with food: emotional eating, restrained eating, and intuitive eating.

• Emotional Eating: This involves eating in response to negative emotions like stress or sadness, often turning to comfort foods for temporary relief. While it may offer short-term solace, emotional eating can lead to overeating, weight gain, and a disruption of natural hunger cues, affecting both physical and mental health.
• Restrained Eating: Restrained or restrictive eating is about controlling food intake to manage weight, often through calorie counting or strict meal plans. However, research shows this method can increase body dissatisfaction, disordered eating patterns, and lower overall well-being, disconnecting individuals from their natural hunger signals.
• Intuitive Eating: A more adaptive approach, intuitive eating focuses on listening to your body’s natural hunger and fullness cues while rejecting rigid diet rules. Research highlights its benefits for mental well-being, weight stability, and a healthier relationship with food.

We also discuss the Acceptance Model of Intuitive Eating, which illustrates how intuitive eating fosters a positive body image and improved mental health by encouraging body acceptance and mindfulness around food.

This episode is your gateway to understanding how these approaches impact not only your physical health but also your mental and emotional well-being.
