“For runners, understanding your blood type can be a game-changer. Knowing which foods work for you not only boosts performance but can also prevent common running injuries.” - Dr Vrzal on Extramilest Show #95​

This was a fascinating conversation with Dr. Vrzal, a holistic chiropractor and author of The Headache Advantage. We explore the connections between nutrition, blood type, and performance, along with insights to become a stronger, healthier and happier athlete.

Many people know their blood type. If not, you can ask your doctor, or buy a Blood Type Diet Home Test Kit for about $10 at places like Amazon.

I realize nutrition can be a controversial topic, but I wanted to share something that is fascinating to me.

A few quotes from Extramilest Show #95 by Dr. Vrzal:

• On Athletic Performance: "Understanding your blood type can help optimize your training. It's not just about what you eat - it's about how your body processes stress, handles intensity, and recovers from workouts. What works for one athlete may exhaust another based on their blood type."
• On Blood Type and Performance: "The A blood type tends to be a higher cortisol-producing person. This means they need to be more careful with high-intensity training and may find their 'happy place' in marathon-type events. O blood types tend to handle intensity better and often excel at shorter distances like half marathons.
• "On Nutrition by Blood Type: "For blood type A, avocados are a miracle food, while for O types, avocados can crash their immune system."
• On Mineral Balance: "During long training days, we lose tons of minerals through sweat. Minerals help us be stronger and more resilient when stress hits. That's why electrolyte replacement can make such a difference in recovery and performance."
• On Food Journaling: "Keep track of what you eat and how your body responds. Make a note when you have a headache or pain - what did you eat or do yesterday? Eventually, patterns will emerge that show you what foods work for your body type."
