What is Deuterium?

Deuterium is a naturally occurring isotope of hydrogen, containing one proton and one neutron—making it twice as heavy as regular hydrogen.
Found in all water and biological matter, deuterium can accumulate in cells and impair mitochondrial function. Research indicates that high
deuterium levels may contribute to cancer progression by disrupting cellular energy production and DNA repair.

Foods High in Deuterium


Certain foods naturally contain higher levels of deuterium, and minimizing their intake is recommended for cancer patients seeking to
optimize mitochondrial health and reduce tumor growth.

  • Grains and Starches: Wheat, rice, oats, corn, and other grains are rich in deuterium. Bread, pasta, and processed cereals should be avoided.
  • Sugary Foods: High-fructose corn syrup, refined sugars, and processed sweets contain elevated deuterium levels.
  • Starchy Vegetables: Potatoes, sweet potatoes, yams, and carrots are high in carbohydrates, which elevate deuterium.
  • Legumes and Beans: Lentils, chickpeas, and beans are dense in carbohydrates, increasing cellular deuterium.
  • High-Water Fruits: Watermelon, grapes, bananas, and oranges have higher deuterium concentrations due to their water content.

Foods Low in Deuterium


Focusing on foods low in deuterium supports mitochondrial health, reduces oxidative stress, and enhances the body’s ability to combat cancer.

  • Grass-Fed Meats and Wild-Caught Fish: Beef, lamb, salmon, sardines, and mackerel are naturally low in deuterium.
  • Healthy Fats: Coconut oil, olive oil, ghee, avocado oil, and grass-fed butter contain minimal deuterium.
  • Low-Starch Vegetables: Spinach, kale, broccoli, cauliflower, and leafy greens are low in carbohydrates and deuterium.
  • Nuts and Seeds: Almonds, macadamia nuts, chia seeds, and flaxseeds are nutrient-dense and low in deuterium.
  • Berries: Blueberries, blackberries, raspberries, and strawberries have low deuterium levels and are rich in antioxidants.
  • Eggs (Pasture-Raised): High-quality eggs from pasture-raised hens are low in deuterium and packed with nutrients.

The Ideal Cancer Patient Diet for Deuterium Depletion


To maximize mitochondrial health and support cancer recovery, follow a low-deuterium, ketogenic-based diet:

  • Ketogenic Foundation: High in healthy fats, moderate in protein, and very low in carbohydrates.
  • High-Quality Fats: Coconut oil, avocado oil, olive oil, grass-fed butter, and ghee for sustainable energy.
  • Grass-Fed and Pasture-Raised Proteins: Include grass-fed beef, lamb, wild-caught fish, and pasture-raised eggs.
  • Low-Starch, Leafy Vegetables: Spinach, kale, broccoli, cauliflower, and asparagus rich in antioxidants and vitamins.
  • Hydration with Deuterium-Depleted Water (DDW): Drinking DDW helps flush excess deuterium from the body.
  • Avoid High-Deuterium Foods: Eliminate grains, processed sugars, high-starch vegetables, and conventional fruits.

Supportive Strategies for Lowering Deuterium

  • Intermittent Fasting: Reduces glucose levels and encourages fat metabolism, naturally depleting deuterium.
  • Cold Therapy (Cryotherapy): Enhances mitochondrial efficiency and reduces deuterium.
  • Hyperbaric Oxygen Therapy (HBOT): Increases oxygen delivery to cells while lowering deuterium concentrations.
  • Exercise: Boosts mitochondrial function and promotes fat-based energy utilization.
