    Preventing Cancer: What Every Young Person Needs to Know

    Cancer is no longer just a disease of old age. Early-onset cases have surged 80% since 1990, with colorectal, breast, prostate, uterine, and lung cancers rising fastest. In 2024, over 2 million Americans will be diagnosed, many under 50. Colorectal cancer is now a leading cause of death in men under 50 and is climbing sharply in young women. The question is: why is this happening, and how can we protect ourselves? Listen on⁠ Spotify⁠,⁠ Apple⁠,⁠ Amazon Music⁠,⁠ iHeart Radio⁠, or anywhere you listen to podcasts. Things Mentioned: Air Pollutants: PM2.5 (from cars, factories) and benzene (from smoke, industry) lead to respiratory and heart problems. Find our what to do about air pollutants here. A review published in Environmental Health Perspectives inks prolonged exposure to these toxins with significantly higher cancer risks, especially in industrialized countries. You can learn more about these risks in my book, The Non-Toxic Living Guidebook. Lifestyle Habits That Fuel Cancer Excess Sugar and Starch Intake: Cancer cells have an uncanny ability to thrive on glucose, which they use as a primary fuel source. Diets high in sugar and refined starches can elevate blood glucose levels, potentially fueling the growth and spread of tumors by providing cancer cells with the energy they need to multiply. Sedentary Behavior: Leading a sedentary lifestyle doesn’t just contribute to weight gain; it also increases chronic inflammation in the body, which can weaken the immune system’s ability to detect and fight off cancerous cells. Without regular physical activity, the body’s natural defenses are impaired, making it easier for cancer cells to evade detection and grow uncontrollably. Clean Up Your Diet Prioritize whole, unprocessed foods. Increase fiber intake to 30-50 grams daily to promote a healthy gut microbiome. Focus on anti-inflammatory foods like leafy greens, berries, nuts, seeds, and fatty fish. Reduce your consumption of ultra-processed foods, sugar, and refined grains. Exercise Regularly Aim for 150 minutes of moderate activity or 75 minutes of vigorous exercise per week. Not sure where to start? Hit the minimum effective dose of exercise in each oft these categories. Physical activity reduces inflammation, improves blood sugar regulation, and strengthens your immune system. Reduce Toxic Exposure Install an RO Water System: Filter out contaminants from your drinking water for cleaner hydration. Avoid Heating Plastic: Switch to glass or stainless steel to prevent harmful chemicals from leaching. Use an Air Purifier: Improve air quality by filtering out allergens and toxins in your home. Go Organic (Dirty Dozen): Choose organic produce, especially for high-pesticide items like strawberries and spinach. Use Non-Toxic Cleaning Products: Opt for natural cleaners made from vinegar, baking soda, or essential oils. Choose Non-Toxic Baby Products: Select safer toys and products to limit your baby’s exposure to chemicals. Use Glass or Stainless Steel Bottles: Replace plastic bottles to avoid BPA and other toxins. Avoid Chemical Air Fresheners: Use essential oils or natural scents instead of synthetic air fresheners. Avoid Non-Stick Cookware: Use stainless steel, cast iron, or ceramic pans to avoid toxic chemicals. Use Chemical-Free Laundry Detergents: Switch to plant-based detergents and avoid dryer sheets. Supplement Wisely Vitamin D3: Maintain blood levels of at least 40-50 ng/mL. Omega-3 Fatty Acids: These reduce inflammation and support overall health. These are the best fish to eat. Probiotics: Promote gut health, which is closely linked to cancer prevention. Antioxidants: Found in green tea, turmeric, and dark leafy greens, these combat free radical damage.

    E87 · 15 Sibling Rivalry Solutions That Work

    Sibling disagreements can feel exhausting in the moment, yet they’re also some of the best real-life practice kids will ever get for navigating relationships. When parents step in with the right mix of guidance and space, these everyday clashes can turn into lessons in patience, empathy, and problem-solving. The goal isn’t to eliminate conflict, it’s to help children learn how to work through it. Handled well, those tense moments can shape stronger bonds at home and prepare kids for healthier, more respectful connections in the world beyond your front door. Listen on⁠ Spotify⁠,⁠ Apple⁠,⁠ Amazon Music⁠,⁠ iHeart Radio⁠, or anywhere you listen to podcasts. Things Mentioned: Check out this article on sibling rivalry. Engaging in other sensory seeking activities One of my favorites is The Color Monster but here is a full list of recommended books by age. Research highlights that it’s not the frequency of conflict children witness but how conflict is handled that matters. According to Adam Grant in his book Think Again, children who observe respectful disagreements between parents—who “clash constructively”—are likely to feel emotionally safer and, in the long term, become more compassionate and helpful toward their peers. Using interception and learning to recognize these signals not only reduces conflicts but also empowers kids to manage their own emotions more effectively.

    E86 · What are the Healthiest Fish to Eat? (and What to Avoid).

    Fish are nutritional powerhouses, packed with high-quality protein, essential vitamins and minerals, and heart-healthy omega-3 fatty acids. Regular consumption has been linked to better brain function, lower inflammation, and reduced risk of chronic diseases like heart disease, stroke, and type 2 diabetes. The American Heart Association recommends eating fish at least twice a week to enjoy these benefits. But not all fish are created equal. Some species contain harmful toxins—like mercury, PCBs, and dioxins—that can build up in the body, leading to health issues ranging from brain fog and fatigue to serious conditions like diabetes and cancer. I used to stick to light tuna and tilapia, thinking I was making a healthy choice—until I dug deeper into the research. Here’s what I found about which fish to enjoy regularly and which to limit or avoid. Listen on⁠ Spotify⁠,⁠ Apple⁠,⁠ Amazon Music⁠,⁠ iHeart Radio⁠, or anywhere you listen to podcasts. Read the Article: What are the Healthiest Fish to Eat? (and What to Avoid) Things Mentioned: The healthiest type of fish to eat are S.M.A.S.H. fish. S.M.A.S.H. stands for salmon, mackerel, anchovies, sardines, and herring. These fish have lower levels of toxins and higher levels of omega-3’s because they are lower on the food chain.  Choose fish that are wild-caught and sustainably sourced when you can. The two best brands are Wild Planet and Season. The top three most popular seafood for Americans are shrimp, salmon, and then tuna. But when you head to the canned fish section of the grocery store it’s a minuscule amount of non-tuna and unlimited options for tuna. Look for albacore that was pole-and-line caught or troll caught. This means that they’re not caught using the purse seine method which is basically giant nets cast over schools of fish. This results in lots of “bycatch” resulting in the unnecessary killing of sea turtles, sharks, and other sea life. The best brand I’ve found is Wild Planet tuna with American Tuna coming in at a close second. Okay, so those fish are the healthiest but what about finding fish that are sustainably caught? Seafood Watch by the Monterey Bay Aquarium is the best resource for this. It breaks up fish into 3 levels: “best choice,” “good alternative,” and “avoid,” which are “based on scientific criteria of environmental sustainability.”   Beyond that, look for fish with these labels (e.g. “Dolphin Safe” and “Friend of the Sea”) which have the highest standards. Side note: Here’s an interesting article about how one fisherman rebranded the “toothfish” to “Chilean sea bass” to get it accepted into the world of seafood. What To Do If You Hate Fish: I get it. Most fish have a very distinct taste and even the ones that don’t (e.g. tilapia) have a unique texture. Start by combining it with foods you like (fish tacos anyone?), eating it at a nice restaurant where it will likely be cooked well, dipping it into some healthy sauces, or even doing a little exposure therapy by gradually increasing the amount you mix into a chicken salad, ceviche, or some other concoction. As a family, we have a seafood entree (typically salmon) about once a week. While my kids were more open to the oily fish during BLW, I haven’t done a great job exposing them to much beyond tuna, tilapia, salmon, and the variety of fish in sushi (knowing it’s great for their mental health among other things). I have experimented with gluten-free fish sticks from Whole Foods but they don’t love the taste, I don’t love that canola oil is an ingredient and they don’t meet any standards for being wild-caught or sustainable. Note to self: more fish for kids.

    E85 · 12 Signs You’re Not as Healthy as You Think You Are

    You work out, eat mostly well, and get some sleep—so you’re probably in good health, right? Not necessarily. Health isn’t just about hitting the gym a few times a week or drinking a green smoothie now and then. Your body constantly gives feedback on how well it’s functioning, and if you’re not paying attention, small signs can turn into bigger problems down the line. Here are 12 signs that your health might not be as solid as you think—and exactly what to do about it. Listen on⁠ Spotify⁠,⁠ Apple⁠,⁠ Amazon Music⁠,⁠ iHeart Radio⁠, or anywhere you listen to podcasts. Things Mentioned: You’re Always Tired, No Matter How Much You Sleep Get morning sunlight and limit screen time before bed to reset your circadian rhythm. If you can’t get outside early then consider a light therapy lamp for 20 minutes. Cut caffeine around noon to prevent sleep disturbances. Consider tools like a sleep mask and white noise machine. You Bruise Easily Increase collagen intake—bone broth, gelatin, or collagen powder. Consider a high-quality multivitamin. You Get Sick Too Often—Or Never Get Sick at All Support your gut—70% of your immune system lives there. Eat fermented foods, fiber, and avoid ultra-processed junk. Check your vitamin D levels—low levels are linked to immune dysfunction. Consider a vitamin D3 supplement. Your Nails Are Brittle or Have Ridges Eat more collagen, protein, and silica-rich foods (like cucumbers and bell peppers). If you have vertical ridges, check your magnesium and B vitamin intake. Consider a multivitamin if these are low. You Have Cold Hands and Feet All the Time Boost nitric oxide naturally—eat beets, dark chocolate, and leafy greens. Try contrast showers or sauna sessions (or both cold plunge and saunas) to improve circulation. You Can’t Skip a Meal Without Feeling Miserable Reduce reliance on carbs—prioritize protein, healthy fats, and fiber to keep blood sugar stable. You Snore Use nasal strips. The brand Breathe Right makes a variety of nasal strips including “original,” extra strength,” and “clear". Use mouth tape. I do this most nights and it has been a game-changer. SomniFix is a great brand that’s easy to apply and stays on all night. Use the promo code MINDBODYDAD for 10% off. You Have Acne Reduce inflammatory foods like seed oils, refined sugar, and dairy (for some, dairy can trigger breakouts). Support gut health with probiotics, fiber, and fermented foods. Track your blood sugar to see if your body responds to certain foods with sharp glucose spikes throughout the day. Optimize vitamin A, zinc, and omega-3 intake—these nutrients play a major role in skin repair. See what supplements I use to incorporate these. You Can Do Pull-Ups, But You Can’t Run 3 Miles (Or Vice Versa) Train both anaerobic and aerobic systems—mix strength work with zone 2 cardio. Include functional movements like kettlebells, sled pushes, and loaded carries for total-body fitness. This is equipment I use in my home gym to keep me active. You’re Always Bloated Consider digestive enzymes or apple cider vinegar before meals if bloating persists You Have Frequent Headaches Stay hydrated and get enough high-quality electrolytes—this is a common headache trigger. Consider using a Continuous Glucose Monitor to monitor your blood sugar in real time. You Crash Hard After Lunch Ditch the sugar and processed carbs—bread, pasta, and fries might taste great, but they set you up for a crash later. Get outside after eating—a 10-15 minute walk after lunch helps regulate blood sugar and keeps energy steady. Don’t overdo caffeine in the morning—too much coffee early on can make your afternoon crash even worse. Stay hydrated and get enough high-quality electrolytes.

    E82 · 7 Supplements That Help Reduce Anxiety & Stress

    Anxiety and stress are constant companions in today’s fast-paced, tech-driven world. While mindfulness and therapy are key for mental health, nutrition and supplementation often get overlooked. What we eat directly affects brain chemistry, inflammation, and how our bodies handle stress. Unlike our ancestors, who thrived on nutrient-dense diets and natural remedies, modern lifestyles often leave nutritional gaps. Supplements can help fill those gaps, supporting the body’s stress response and promoting calm. Research shows certain nutrients and adaptogens reduce anxiety by balancing stress hormones, aiding neurotransmitters, and lowering inflammation. This guide highlights evidence-backed supplements, from ancient herbs like ashwagandha to modern favorites like L-theanine, that can boost resilience and restore mental clarity alongside a healthy diet and lifestyle. Listen on⁠ Spotify⁠,⁠ Apple⁠,⁠ Amazon Music⁠,⁠ iHeart Radio⁠, or anywhere you listen to podcasts. Things Mentioned: Ashwagandha Recommendation: Tribe Organics Ashwagandha KSM 66 Pure Organic Root Powder Extract (>5% Withanolides) Omega-3 Fatty Acids I eat S.M.A.S.H fish at least a couple of times per week and on days I don’t I supplement with about 2g of EPA and DHA/day. Recommendation: Performance Lab Omega-3 St. John’s Wort Recommendation: Nutricost St. John’s Wort Lemon Balm Recommendation: Organic Lemon Balm Tea L-Theanine Reccomendation: Nutricost L-Theanine Saffron Recommendation: Nutricost Saffron Extract B Vitamins Recommendation: Nutricost Vitamin B Complex. You can also opt to choose a reputable multivitamin like this one from Performance Lab How to Use These Supplements Start Small: Introduce one supplement at a time to gauge its effects. Pair with Food: Many supplements, like saffron and ashwagandha, are better absorbed when taken with meals. Consult a Professional: Always speak with a healthcare provider before starting new supplements, especially if you’re on medication or have pre-existing conditions.

    E81 · What Is The Minimum Effective Dose Of High Intensity Interval Training?

    Previously, I explored the minimum effective doses for Zone 2 cardio and strength training. Today, I’m shifting focus to perhaps my favorite workout style: high-intensity interval training (HIIT). What draws me to HIIT is its intensity and brevity, plus the flexibility to choose exercises, whether sprints, cycling, or kettlebell swings, and control the length of each interval, from 10 seconds up to 4 minutes. These workouts hit the sweet spot between cardio and strength, packing a powerful punch in less time than either alone. The big questions are: How short can these sessions be? And how often should you do them? What I really want to uncover is the minimum effective dose of HIIT, the least amount of work needed to get or stay fit without overdoing it. Listen on⁠ Spotify⁠,⁠ Apple⁠,⁠ Amazon Music⁠,⁠ iHeart Radio⁠, or anywhere you listen to podcasts. Read The Article: What Is The Minimum Effective Dose Of HIIT? Things Mentioned: In past articles, I’ve covered the minimum effective dose of Zone 2 training and strength training. Today I’ll dive into maybe my favorite type of workout: high-intensity interval training. I love it because it’s intense, it’s short, and, unlike those other types of workouts, I have more say in the kind of exercise (sprints, cycling, kettlebells, etc.) and the duration of each set (10 seconds or 4 minutes?). The workouts are that sweet spot between cardio and strength training but intense enough that they’re typically shorter than both. For HIIT, I typically use a jump rope, kettlebell (swings, hip hinges, squats, overhead press, rows), resistance bands (rows, shoulder pulls, lat pulldowns), and do body weight work (push-ups, plyo jumps), Occasionally, I’ll also incorporate a HIIT workout into my morning or nighttime writing. As I’m typing away, I am sitting on a FlexiSpot Desk Bike. I jack the resistance up to 8, set an interval timer for 30 seconds every 3 minutes, and then I just pause my writing for that time and go.
