Intermittently challenging yourself, be it through temperature changes like cold or heat, other types of stressors, such as physical activity, or even dietary compounds in plants such as polyphenols or flavonoids, is beneficial to the body. These intermittent challenges activate genetic pathways that help you deal with normal metabolism and immune function stress. This concept is known as hormesis.  Hormesis is a little bit of stressful challenge that activates the stress response pathways in a beneficial way. It has a profound antioxidant and anti-inflammatory response.

Challenge yourself intermittently to improve health

Sulforaphane is a sulfur-rich compound found in cruciferous vegetables such as broccoli, broccoli sprouts, brussel sprouts, cauliflower and cabbage. It activates a powerful detoxification pathway which helps you detoxify things like carcinogens that you’re exposed to. Clinical studies have linked the benefits of sulforaphane to a variety of chronic diseases such as autism, aflatoxin toxicity, cancer, air pollution toxicity, cardiovascular disease, diabetes, and more.

Being deficient in magnesium makes it more difficult to make Vitamin D. Magnesium is also involved in making ATP, the energetic currency of our cells.  Our bodies need ATP to do anything, including repairing DNA enzymes. You can’t look in the mirror and see DNA damage from lack of magnesium, but it is there.  Dark leafy greens are high in magnesium, for example, kale, spinach, chard, and romaine lettuce. Magnesium in dark leafy greens is less bioavailable, but cooking can release it. For supplementation, magnesium malate would be best.

Vitamin D is essential for various aspects of our brain and body health. Vitamin is a steroid hormone we produce when we’re in the sun, depending on how much melanin we have on our skin, whether or not we’re wearing sunscreen, and how old we are.  Vitamin D gets converted into a steroid that regulates some of the human genomes and plays an important role in activating the innate immune system. Vitamin D3 is a good way to supplement. Vitamin D2 is often a plant source.

Cold exposure (11 minutes per week, up to the neck) has been shown to increase brown fat which increases metabolism and the ability to feel comfortable in cold temperatures. 		 Regular use of sauna and other heat exposure can reduce mortality by cardiovascular events, stroke, and all-cause mortality. Heat changes the way in which proteins are configured at the molecular level: Heat shock proteins (HSP) ensure cells of the brain and body don’t misfold. <ul><li>Recipe for heat exposure: 57 minutes per week spread out across sessions. </li><li>Cold exposure (safe but cold) a couple of times a week.</li></ul>

Deliberate hot and cold exposure

Sulforaphane levels in broccoli are lower when it's cooked. But adding one gram of mustard seed powder to cooked broccoli increases the sulforaphane by fourfold.  The plant, Moringa, has similar effects to broccoli. This can be bought in a powdered form and added to smoothies.

Broccoli - raw or cooked

Omega 3 fatty acid is another essential macronutrient. People with low omega-3 index have higher all-cause mortality and lower lifespan. <ul><li>Wild game has a higher concentration of micronutrients (e.g., zinc) and omega-3 versus conventional.</li><li>Grass-fed meat is better as factory farmers feed cows corn to fatten them.</li><li>Fish is a great source of omega 3 but is higher in mercury. </li><li>Plant sources of ALA would be walnuts and flaxseeds. If you’re a vegan or vegetarian, the best it to supplement with microalgae oil as they have DHA.</li><li>Supplementation is a good way to get a high dose of Omega 3s.</li></ul>

How To Live A Long Life

This podcast focuses on micronutrients that are essential for brain and body health. 

My guest is Rhonda Patrick, Ph.D. She earned her doctoral degree in biomedical science from St. Jude Children’s Research Hospital at the University of Tennessee Health Science Center and has become one of the leading public health educators on the brain and general health, aging, cancer, and nutrition. We discuss the four major categories of micronutrients that regulate cellular and organ stress and antioxidants, inflammation, hormone regulation, immune system, and longevity. Dr. Patrick provides actionable protocols for obtaining key micronutrients from food and/or supplement-based sources. Additionally, Dr. Patrick outlines protocols for deliberate cold and deliberate heat exposure to benefit metabolism, cardiorespiratory fitness, mental health, and lifespan.  Thank you to our sponsors AG1 (Athletic Greens): https://athleticgreens.com/huberman Thesis: https://takethesis.com/huberman InsideTracker: https://insidetracker.com/huberman See Andrew Huberman Live: The Brain Body Contract Tuesday, May 17th: Seattle, WA Wednesday, May 18th: Portland, OR https://hubermanlab.com/tour Our Patreon page https://www.patreon.com/andrewhuberman Supplements from Momentous https://www.livemomentous.com/huberman.

Huberman Lab discusses neuroscience: how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health. We also discuss existing and emerging tools for measuring and changing how our nervous system works. Dr. Andrew Huberman is a tenured professor of neurobiology and ophthalmology at Stanford School of Medicine. His laboratory studies neural regeneration, neuroplasticity, and brain states such as stress, focus, fear, and optimal performance. For more than 20 years, Dr. Huberman has consistently published original research findings and review articles in top-level peer-reviewed journals, including Nature, Science, Cell, Neuron, and Current Biology. He is a regular member of several National Institutes of Health review panels and a Fellow of the McKnight Foundation and the Pew Charitable Trusts. Dr. Huberman regularly consults for technology development companies, professional athletic organizations, and various units of U.S. and Canadian Special Operations.
