These 7 Superfoods Are Secretly Wrecking Your Body

Dave Asprey

Dec 30, 2025

Episode description

This solo masterclass on oxalates explains why many people who eat clean still struggle with joint pain, kidney stones, fatigue, brain fog, and chronic inflammation. You’ll learn how oxalates behave very differently from other plant compounds like lectins, phytates, and salicylates. Unlike those compounds, oxalates physically bind minerals and form microscopic crystals that can lodge in tissues, damage mitochondria, and accumulate over time. This episode will change how you think about superfoods, clean eating, and long term human performance.

Host Dave Asprey walks you through the real science of oxalates using decades of self experimentation, functional medicine research, and hands on biohacking. As the founder of the biohacking movement, Dave has tested fasting, ketosis, carnivore strategies, supplements, nootropics, sleep optimization protocols, and metabolic interventions to uncover what actually improves resilience, neuroplasticity, and mitochondrial function without unnecessary damage. 



In this masterclass, you’ll learn why oxalates cause problems even when digestion seems fine, why symptoms can show up in joints, kidneys, nerves, skin, and old injuries, and why reducing oxalates too fast can make you feel worse before you feel better. Dave explains oxalate dumping, candida driven oxalate overload, microbiome interactions, and why foods like spinach, almonds, cacao, and green smoothies often backfire over time. He also shares practical ways to lower your oxalate load safely, support mineral balance, and protect your metabolism and brain using a Smarter Not Harder approach. 



This episode is for you if you eat “healthy” but still feel off, deal with unexplained pain or inflammation, or want to improve longevity, brain optimization, sleep, and human performance without extreme restriction. 



You’ll Learn: 

• Why oxalates are different from lectins, phytates, and other plant toxins 

• How oxalates drain minerals and damage mitochondria 

• What oxalate dumping feels like and how to avoid it 

• Which superfoods cause the biggest problems and what to replace them with 

• How hydration, minerals, and supplements affect oxalate clearance 

• Why oxalates accelerate aging and tissue stiffness over time 

• Practical biohacking strategies to protect longevity and human performance

Mindsip insights from this episode:

Test oxalate sensitivity by monitoring pain after high-oxalate meal

You can test your sensitivity by eating a high-oxalate meal and observing if old injuries, joints, or your lower back hurt more over the next 24 hours.

Reconsider almonds as a special treat, not a daily health food

Contrary to popular belief, almonds and almond flour are exceptionally high in oxalates and should be considered a special treat rather than a daily health food.

Address nerve pain caused by oxalate crystals in nerves

Oxalate crystals can form on the lining of your nerves, creating the internal equivalent of being stuck with a needle and causing unexplained neuropathic pain.

Reduce oxalate intake to combat tissue fibrosis and aging

Excessive oxalates can cause tissue fibrosis (cellular stiffening), which is a hallmark of aging, by essentially sandpapering your inner organs and tissues.

Avoid megadosing vitamin C to prevent oxalate issues

Your body's metabolism can convert high doses of vitamin C or glycine into oxalates, potentially causing more problems than they solve.

Address oxalate issues to prevent recurring UTIs

Recurring urinary tract infections may not be a bacterial issue but rather an oxalate problem, where sharp crystals cut the urethra, allowing bacteria to reinfect it.

Identify rapid plaque buildup as a sign of oxalate secretion

If you get rapid plaque buildup on your bottom inside teeth, it could be a sign that glands are secreting oxalate crystals directly into your saliva.

Transform your phone into a skin health ally with red light therapy

A unique screen protector called the Bodyguardz Red Light Converter can convert harmful blue light from your phone into beneficial red light, supporting skin health and sleep.

Avoid sudden oxalate cessation to prevent dumping effects

If you suddenly stop eating oxalates, your body may release its stored reserves in a process called 'oxalate dumping,' causing temporary rashes, joint pain, and fatigue.
