📝 Podcast Summary

Understanding the Biology of Emotions and How to Control Them

Understanding the biology of emotions and how they arise in our brain and body can equip us with tools to regulate, change and steer our emotions. The nutrients we ingest impact the chemicals in our brain that give rise to emotions. By relying on specific pathways in the body, we can shift from being slightly depressed to feeling happier or from feeling too alert and anxious to feeling calmer. Emotions have a long and rich history and understanding the push-pull of attraction and aversion is foundational in any discussion about emotions. Utilizing scientific data and grounded tools, we can change our moods and emotions and live a fulfilling life.

Understanding the Brain-Body Connection Through the Basal Ganglia and Vagus Nerve

Our brain and body are connected through the circuits in the basal ganglia which allow us to move towards or away from things, either through attraction or aversion. The vagus nerve, which is a two-way street carrying both sensory and motor information, plays a crucial role in regulating our emotional states and governing the brain-body connection. It senses information from various organs of the body and sends it up to the brain, as well as controlling motor behavior from the brain back to the body. It's important to note that simply 'stimulating' the vagus is not always beneficial as it also senses contaminants in our body and can lead to fever. Understanding how to use the vagus can help steer various aspects of our mood and wellbeing.

The misunderstood vagus nerve and its role in behavior and bodily sensations.

The polyvagal theory, while having some cool concepts, has been misused and misunderstood in popular psychology. To truly understand the vagus nerve, think of it like the eyes: it detects and informs the brain about various bodily features such as gut fullness and heart rate. The presence of sugary foods within the stomach can trigger the vagus nerve to release dopamine, creating a craving for more sugar. This shows that the body has circuits driving our behavior and making us feel good, even without conscious perception. Understanding the role of the vagus nerve in bodily sensations and behaviors can lead to better ways to feel and relieve certain conditions.

The Role of Body in Food Cravings and Relationships

Our attraction to certain foods and people is not solely based on our thoughts, feelings, or perception, but on the information our body receives. Hidden sugars in savory foods can make us crave them without realizing it. The lateral hypothalamus in our brain inhibits feeding while the locus coeruleus releases adrenaline and creates alertness when we approach food. Pre-meal anxiety is due to this interaction between the two, and tools like mindfulness can improve your relationship with food.

Amino Acid Sensors and Their Impact on Our Health and Diet

Our brain perceives adequate intake of amino acids which are important for both repairing muscle and creating neurochemicals in the brain. Our gut is constantly sensing what's in our food, including sugar, fats, contaminants, and amino acids through parallel pathways that regulate our desire to eat more or less of something. The quantity and array of amino acids in our food impact our neurological and motivational states, including dopamine release which affects our expectations and desires. These amino acid sensors help us determine when we've had enough to eat, influencing our dietary choices and desires. It's important to understand and nourish our body's amino acid needs for optimal health and wellbeing.

The Role of Dopamine in Motivation and Desire

Dopamine neurons that drive feelings of good or desire reside in the brain, and not in the gut. Parkinson's disease is associated with deficits in dopamine neurons, leading to depression and blunted motivation. L-tyrosine-rich foods can promote healthy dopamine production, but excessive use of L-tyrosine supplements or drugs that activate dopamine and epinephrine can lead to addictive properties and negative side effects. Dopaminergic antidepressants like Wellbutrin can increase motivation and alertness, but also have potential side effects like anxiety, sweating, and pupil dilation. The brain-body connection is mediated by the vagus nerve, with dopamine production being a key factor in determining our motivation and desire.

Sugar's Impact on Our Mood and Brain

Sugar isn't just impacting our blood glucose, it is disrupting our dopamine systems at a subconscious level. The neuromodulators serotonin and dopamine regulate our moods and emotions, with serotonin making us feel comfortable and dopamine and epinephrine putting us in pursuit of things. Antidepressants work by preventing the re-uptake of serotonin into neurons after it’s been released, which leads to more overall serotonin, helping people feel better in cases of depression and other clinical disorders. Serotonin impacts our mental state and most of it is in the neurons of the brain, not in our gut where people thought it was. It's fascinating how events in the gut impact the serotonin in the brain that controls our mood. Unfortunately, there aren't really great ways to measure these things outside the clinical setting.

The Relationship between Food and Mood

Food plays a significant role in regulating our mood, alertness, and wellbeing as it contains amino acids that act as precursors to neuromodulators. While some people adjust their serotonin levels by eating carbohydrate-rich foods, others take supplements like 5 HTP. However, caution should be exercised while taking such supplements for prolonged periods as they can disrupt the natural production of serotonin. If you are interested in exploring the effects of supplements like 5 HTP or Macuna Pruriens, consult with your doctor and refer to resources like that provide links to peer-reviewed studies. Ultimately, entrepreneurs can leverage this opportunity to create accurate at-home tests for people to monitor their serotonin levels.

The Benefits and Science behind Macuna Purina and How Food Affects Our Emotions

Macuna Purina contains L-DOPA, the precursor to dopamine, along with other psychoactive molecules, and has been shown to have several benefits such as improving sperm motility, reducing symptoms of Parkinson's disease, increasing testosterone, and subjective wellbeing. Food has chemical effects on our body and we can bias certain effects by consuming foods that are rich in certain compounds such as El Tyrasine. Lisa Feldman Barrett's book 'How Emotions are Made' is a great read to understand the psychology and subjectivity of emotions. Ingesting supplements or foods affects our brain through the gut-brain connection and not by directly putting substances into the brain.

How Nutrients Impact Mood and Depression

The omega-3 to Omega six fatty acid ratio has a profound effect on depression and mood. Ingesting certain nutrients can impact mood and behavior which includes dopamine and serotonin pathways. Certain foods like Morrell and tyrosine can lead to an increase in dopamine. Proper food choices combined with exercise show positive effects in mood and anxiety. Mediation and social connection are also important factors to consider. A study found that a thousand milligrams of EPA compared to 20 milligrams of fluoxetine was equally effective in reducing depressive symptoms. Ingesting certain foods allows the body to inform the brain, shifting one’s mood.

The Benefits of Taking EPA in Fish Oil for Depression and Heart Health

Taking a thousand milligrams per day of EPA in fish oil can have a profound effect on mood and can relieve both forms of depression. EPA has a synergistic effect with flu oxytocin and can amplify or improve the effect of low dosages of some SSRI antidepressants. However, people who have blood conditions and women who are taking birth control should consult their doctor before taking fish oil. Fish oil can also have side effects like fishy breath, which can be avoided in some products. Increasing the amount of EPA in the diet can shift the Omega-3 to Omega-6 ratio, which is important for reducing inflammation and can help in non-responders to antidepressants. Heart rate variability is important for heart health and increasing the amount of EPA in the diet can improve HRV.

The Role of Omega-3 in Reducing Depression Symptoms and Improving Mood

A higher omega-3 to Omega-6 ratio decreases inflammation markers and increases heart rate variability, allowing antidepressants to work even at low doses. EPS ingestion through food or supplementation can lead to mood improvement and reduced depression symptoms. However, no one compound, supplement, or drug alone can completely shift one's experience of life. Proper behaviors such as sleep, exercise, social connection, and food are essential. Omega-3s can be obtained from various sources, including fish oil, krill oil, chia seeds, flax seeds, and meats. When selecting fish oil, it is crucial to consider its sources and contaminants. A rancid taste indicates a contaminated fish oil that should be avoided.

The many benefits of L-carnitine as a supplement.

L-carnitine is a supplement that has impressive effects on depression, pregnancy rates, sperm quality, and symptoms of autism. It also has potential benefits for treating certain forms of addiction and reducing symptoms of fibromyalgia. L-carnitine is a seed elated and converted into a form that gets across the blood-brain barrier and is involved in mitochondrial activation, long chain fatty acids. It has positive effects on ammonia, C-reactive proteins and lowers blood glucose levels. The effects on depression are still emerging, but seven studies have shown a notable decrease in depressive symptoms. Check it out on for dosages and more information.

The Gut Microbiome and Gut Brain Axis Connection Explored

The gut microbiome and gut brain axis have a deeper connection than what's often portrayed. The microbiota present in our digestive tract have their own adaptive behavior, exploiting our bodies to proliferate. The quality of the mucosal lining in our gut is crucial for determining the rate and effectiveness of our digestion, as well as our immune system. While most infections often enter through the mouth and nose, some migrate down into the gut, where certain bacteria adjust the mucosal lining to their needs. Understanding this relationship can have actionable benefits in terms of regulating the gut microbiome through probiotics and prebiotics.

The Importance of a Healthy Gut Microbiome and the Role of Probiotics.

Maintaining a healthy gut microbiome is essential for good mood, digestion, and immune system function. However, it's important to not overdo probiotics as excessive intake can lead to brain fog. The best sources of probiotics come from fermented foods like sauerkraut, pickles, and kimchi. Artificial sweeteners can disrupt the gut microbiome and should be avoided. Saccharin, in particular, has been shown to have negative effects on the gut microbiome. Eating small amounts of fermented foods can improve overall mood and may be effective in treating certain psychiatric illnesses.

The truth about artificial sweeteners and gut microbiome

The narrative around artificial sweeteners and gut microbiome is incorrect. Certain artificial sweeteners disrupt the microbiome and shift it either in a positive or negative way. The ketogenic diet and vegan diets also create dramatic shifts in the gut microbiome, but the effects are highly individual and depend on each person's genetic makeup and early life conditions. Ingestion of processed foods, regardless of animal or non-animal sources, tend to create activity within the body that leads to overconsumption of calories and weight gain. To promote a healthy microbiome, it's important to find the right diet for each individual.

Supporting the Microbiome and Digestive Health through Fermented Foods and Mindful Eating

To support your microbiome and overall health, aim to consume at least two servings of fermented foods per day. Supplements can be helpful in low levels, but high levels can lead to brain fog. The gut microbiome is highly contextual, impacted by factors like exercise and social well-being. While fasting can have benefits, prolonged periods of fasting can deplete the gut microbiome and impact digestion and assimilation of nutrients. Gradually reintroducing foods after a fast is recommended. Our beliefs can also impact how our brain and body respond to food, as seen in experiments measuring ghrelin levels in response to milkshake consumption.

The impact of our beliefs on our physiology

Our beliefs and subjective feelings can have a significant impact on our physiology through top-down mechanisms or modulation of our physiology. This was demonstrated by Dr. Crumb's experiment, where the belief that cleaning and taking care of the hotel was good for their health resulted in lower blood pressure, significant body fat loss, and a more enjoyable work experience. These belief effects cannot be achieved by simply lying to oneself, as subjects in the experiment had no prior knowledge about the effects of their daily routine on weight loss and blood pressure. It is important to recognize the interplay between the mind and the body, as our beliefs about certain substances, foods, and nutrients can significantly impact the quality and direction of their impact on our physiology.
