Bret Weinstein & Heather Heying discuss vaccines, scientific consensus, lab leak hypothesis, diet's impact on COVID-19, benefits of fermentation, sea stars, and evolution. They advocate for open investigation, highlight the potential risks of gain of function research, and discuss the protective effects of fermented food and a plant-based diet. They explore the evolution of bilateral symmetry, share their flying experience post-COVID, and emphasize the importance of trusting in the scientific process.

Quick takeaways
Certain dietary factors, including fruits, vegetables, and fermented foods, may influence the severity of COVID-19 symptoms and outcomes.
Factors such as contact with infected individuals, social and occupational contacts, and confinement with infected individuals are strongly associated with increased COVID-19 rates.
Adequate vitamin D levels, obtained through sunlight exposure or diet, are associated with better COVID-19 outcomes and may be a potential strategy for mitigating severity.

Diet's impact on COVID-19: Correlations and insights from Europe and India
Several studies have investigated the potential relationship between diet and COVID-19 outcomes. One study from Europe and India examined the impact of diet on COVID-19 rates and severity. The study found a correlation between certain dietary factors and COVID-19 outcomes. For example, individuals with a diet rich in fruits, vegetables, and fermented foods seemed to have better COVID-19 outcomes. Additionally, adequate vitamin D levels, which can be obtained through sunlight exposure or food sources, were also associated with better outcomes. These findings offer preliminary insights into the potential role of diet in mitigating the severity of COVID-19 infections.
Risk factors and their impact on COVID-19
Various risk factors were analyzed for their impact on COVID-19 rates and outcomes. The study found that factors such as contact with infected individuals, intensity of social and occupational contacts, and confinement with infected individuals were strongly associated with increased COVID-19 rates. In terms of diet, the study highlighted that certain dietary factors, including consumption of fruits, vegetables, fermented foods, and maintaining adequate vitamin D levels, might influence the severity of COVID-19 symptoms and outcomes. These findings emphasize the importance of considering multiple factors, including diet, in assessing COVID-19 risk and outcomes.
Effects of Vitamin D on COVID-19 Severity
One notable finding in the study was the potential role of vitamin D in reducing the severity of COVID-19. Adequate vitamin D levels, either obtained through sunlight exposure or dietary sources, were associated with better COVID-19 outcomes. This aligns with previous research suggesting that vitamin D may have protective effects against respiratory infections. While more research is needed to establish a definitive causal relationship, maintaining adequate vitamin D levels through sunlight or diet could be a potential strategy for mitigating COVID-19 severity.
Dietary Factors and their Association with COVID-19
The study also explored the correlation between certain dietary factors and COVID-19 outcomes. Consumption of fruits, vegetables, and fermented foods was found to be associated with better COVID-19 outcomes. These foods are rich in nutrients and antioxidants that may support the immune system and overall health. However, it is important to note that diet is just one factor among many that can influence COVID-19 outcomes, and further research is needed to fully understand the relationship between diet and COVID-19.
The Relationship Between Diet and COVID Outcomes
A study suggests that fermented foods, such as sauerkraut and yogurt, may have a protective effect against both contracting and experiencing severe symptoms of COVID-19. Regions with high consumption of these fermented foods, like the Balkans and Germany, have lower COVID-19 rates compared to neighboring areas with different cuisines. Additionally, a long supply chain for food, where it goes through several processing steps and travels far from its origin, is associated with metabolic disorders and inflammation, which are risk factors for obesity and poor COVID-19 outcomes.
The Importance of Diet and Food Supply Chains
A plant-based diet high in fiber and fermented foods, along with intermittent fasting, may have positive effects on health and help protect against obesity, metabolic syndrome, and potentially COVID-19. Long supply chains for food, which involve extensive processing and transportation, can lead to the loss of nutritional value and contribute to the obesity epidemic. Trusting the scientific process is crucial, as good science and reliable data over time can lead to more accurate conclusions and better understanding of the world.
In this 65th in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we discuss the state of the world through an evolutionary lens. In this episode, we begin by offering gratitude to Bill Maher and his crew for having us on on January 29—but why didn’t Heather answer his question about vaccines? She does so here, and we discuss a bit more about vaccine technology (also see episode 58 for more on that). Next: What does consensus look like in science, and when are we looking at forced consensus, one which may not accurately reflect underlying reality? What does this have to do with the “lab leak hypothesis” regarding the origin of SARS-CoV2? Following that: how does diet affect COVID—either in terms of mitigating risk of contracting it, or of reducing symptoms if you have it? Short advice: eat more ferment, and buy local. We finish by talking about tuna, and sea stars.
