We've long known that fish is brain food, but new research is shedding light on just how powerful omega-3 fatty acids can be in protecting our cognitive health.
Key Takeaways:
A recent study links higher omega-3 levels to lower rates of dementia
The omega-3 index is a key measure, with levels over 7 being ideal
Benefits are seen for various types of dementia, including Alzheimer's
Fish like salmon and sardines are excellent natural sources of omega-3s
The Science Behind the Benefits
A study published in the Journal of Nutrients in November 2023 analyzed data from the UK Biobank, including:
267,000 participants
Metabolomic data from 102,000 people
Measures of DHA levels and omega-3 index in relation to dementia risk
Types of Dementia Affected
While beneficial for all types of dementia, omega-3s showed the strongest protection against:
Small vessel disease dementia
Lewy body dementia
Other non-Alzheimer's forms of dementia
Alzheimer's disease also saw benefits, though to a lesser extent.
How to Boost Your Omega-3 Levels
Eat fatty fish like salmon and sardines regularly
Consider fish oil supplements if you don't consume enough fish
Aim for an omega-3 index above 7 for optimal benefits
Why It Matters
With dementia rates on the rise globally, finding natural ways to protect our cognitive health is crucial. Omega-3 fatty acids offer a simple, accessible method to potentially reduce your risk of cognitive decline.
The Bottom Line
Whether you prefer grilled salmon, tinned sardines, or a daily fish oil supplement, increasing your omega-3 intake could be one of the smartest moves you make for your long-term brain health.
Remember, while omega-3s are beneficial, they're just one part of a healthy lifestyle. Combine them with regular exercise, mental stimulation, and a balanced diet for the best results in keeping your mind sharp as you age.
So, next time you're at the grocery store or planning your meals, think of your brain and reach for those omega-3-rich options. Your future self may thank you for it!

From Professional Cyclist to Paleo Advocate: A Conversation with Trevor Connor
In a recent episode of the Bionic Health podcast, Dr. Jared Pelo sat down with Trevor Connor, a former professional cyclist turned nutrition expert, to discuss the transformative power of whole-food nutrition and the often-misunderstood principles of the Paleo diet.
An Unexpected Journey to Paleo
Trevor’s story begins with skepticism. As a professional cyclist trained in traditional sports nutrition—which emphasized consuming maximum simple sugars—he initially rejected the Paleo diet concepts taught by Dr. Loren Cordain at Colorado State University. "I sat there in the class, just angry because everything he was teaching me, I'm like, yeah, this is wrong," Trevor recalls.
However, after spending a summer trying to disprove Cordain's teachings through research, Trevor found himself gradually accepting the evidence. The real breakthrough came when he adopted the diet himself: at age 39, after previously retiring from professional cycling, he returned to racing and achieved a top-10 national ranking at age 40.
Debunking the "Simple Sugar" Myth
One of the most significant shifts in Trevor’s understanding came from challenging the conventional wisdom about carbohydrates and simple sugars. While traditional sports nutrition advocated for 65-70% carbohydrate diets, Trevor discovered that focusing on healthy fats and eliminating simple sugars improved both his performance and overall health.
"When I switched to the Paleo diet, [frequent illnesses] went away. I just stopped getting sick," Trevor explains, highlighting how his body responded to the dietary change.
Making Paleo Accessible
Trevor emphasizes that the Paleo diet isn't about rigid rules but rather about eating foods that align with our evolutionary history:
Abundant fruits and vegetables
High-quality meats and fish
Nuts and seeds
Minimal processed foods
Limited or no grains and dairy
He stresses that the diet's success lies in its focus on nutrient density rather than just calorie counting. "When you are eating less processed foods, when you're eating fruits, vegetables, high-quality meats, fish, they're packed with nutrients," Trevor explains.
The Hunger-Nutrient Connection
One of the most fascinating insights Trevor shares is about the relationship between hunger and nutrient deficiency. He suggests that many people overeat because their bodies are seeking specific nutrients rather than just calories. "When we are hungry, our body's usually saying, I need this nutrient or I need that nutrient," he explains, noting how people often find themselves consuming fewer calories but feeling more satisfied when eating nutrient-dense foods.
Practical Tips for Transition
Trevor advocates for a gradual approach to dietary changes, comparing it to athletic training: "If you have a new athlete that's coming off the couch, the thing you would never do with them is say, okay, I'm going to give you a Tour de France athlete's training plan."
His recommendations for getting started include:
Begin by adding healthy foods rather than focusing on elimination
Start with fruits and vegetables
Incorporate higher quality meats
Allow time for taste preferences to adjust
Make gradual changes rather than dramatic overhauls
The 90/10 Rule
Importantly, Trevor dismisses the need for absolute perfectionism in following the diet. "When anybody tries to be 100%, they inevitably fail," he notes. Instead, he encourages people to enjoy occasional treats without guilt, emphasizing that it's better to have real cake occasionally than to constantly seek out "Paleo-approved" versions of processed foods.
Making It Sustainable
Trevor’s personal approach to maintaining this lifestyle is refreshingly practical. He dedicates Sunday nights to meal prep, grilling various proteins for the week ahead and combining them with different vegetables for quick, nutrient-dense meals. This strategy makes healthy eating sustainable even with a busy schedule.

For those interested in exploring the Paleo diet further, Trevor recommends visiting thepaleodiet.com, where you can find recipes, meal plans, grocery lists, and evidence-based information about the diet's principles. The website focuses on making the diet accessible and practical for everyday life.
Through this conversation, Trevor demonstrates that the path to better nutrition isn't about strict rules or dramatic restrictions—it's about making sustainable changes that align with our body's natural needs while acknowledging the realities of modern life.

The Microbiome: Important Yet Mysterious - A Practical Perspective
In recent years, the microbiome has become a buzzy topic in health and wellness circles. But what exactly is it, and how should we approach microbiome health? Let's cut through the hype and look at what we actually know.
What is the Microbiome?
The microbiome consists of all the bacteria living on and in your body:
In your mouth
On your skin
In your intestines
And other areas
While viruses are sometimes included in discussions of the microbiome, they generally don't contribute beneficial effects like bacteria do.
The Testing Dilemma
Despite the growing interest in microbiome testing, there's a catch: comprehensive genomic testing of your full microbiome is prohibitively expensive. This leads to an important question: what's actually worth doing when it comes to microbiome health?
A Practical Approach
Instead of extensive testing, here's what we know works:
Targeted Testing
Focus on testing when there are specific symptoms
Look for specific infections or problems in the intestines
Save comprehensive testing for when it's truly needed
Diet Modifications
Emphasize high-fiber foods
Include foods that specifically feed beneficial bacteria
Recent research highlight: Just half a cup of navy beans daily can increase microbiome diversity and healthy pre/postbiotics
The Current State of Knowledge
It's important to understand that while the microbiome is undoubtedly important, our understanding is still evolving. Think about this: 400 years ago, we didn't even know bacteria were important. Today, we're still uncovering new insights about how these microscopic organisms affect our health.
Key Takeaways
The microbiome is crucial for health
We don't need extensive testing for everyone
Simple dietary changes can improve microbiome health
Focus on practical interventions rather than expensive testing
Our knowledge is growing but still incomplete
The Bottom Line
While the microbiome isn't the "end all be all" of health, it's an important piece of the puzzle. The good news is that you can support your microbiome health through simple, practical steps - particularly through diet - without needing expensive testing or complex interventions.
Remember: Sometimes the simplest interventions, like adding more fiber-rich foods to your diet, can have the most significant impact on your microbiome health.
