Drauzio Varella vs Mark Hyman

Black Coffee

High-quality black coffee, one of the most widely recommended beverages during intermittent fasting. Contains caffeine and chlorogenic acid, which may increase metabolic rate and fat oxidation. Dr. Jason Fung considers black coffee an excellent fasting companion — it suppresses appetite, does not stimulate insulin, and may enhance the metabolic benefits of fasting.

Mixed Berries (Blueberries, Blackberries)

Nutrient-dense berries packed with anthocyanins and polyphenols that support brain health and reduce oxidative stress. Blueberries in particular have been linked to improved memory and cognitive function in clinical studies. A low-glycemic fruit option ideal for daily consumption in longevity-focused diets.

Wild-Caught Salmon

Wild-caught salmon is one of the best whole-food sources of omega-3 fatty acids EPA and DHA. Rich in high-quality protein, astaxanthin, and vitamin D, it supports cardiovascular and brain health. Consuming fatty fish 2-3 times per week is a cornerstone recommendation across longevity protocols.

Fermented Foods (Kimchi, Sauerkraut, Kefir)

Naturally fermented foods rich in live beneficial bacteria to support gut microbiome diversity. Regular consumption of kimchi, sauerkraut, and kefir has been shown to reduce markers of systemic inflammation. A Stanford study found fermented foods increased microbial diversity more effectively than a high-fiber diet.

Broccoli

Broccoli is a nutrient-dense cruciferous vegetable rich in sulforaphane, a powerful compound that activates cellular detoxification pathways. Studies show broccoli consumption supports DNA repair mechanisms and may help reduce inflammation. Longevity researchers recommend broccoli for its ability to activate Nrf2 pathways that protect against oxidative stress and cellular damage.

Dark Chocolate (85%+ Cacao)

High-cacao dark chocolate rich in flavanols and antioxidants. Studies link regular consumption to improved cardiovascular health, lower blood pressure, and enhanced cognitive function.

Magnesium (Threonate/Glycinate)

Highly bioavailable magnesium in threonate or glycinate form for superior absorption. Supports deep sleep quality, cognitive function, and nervous system relaxation. Magnesium threonate is particularly valued for its ability to cross the blood-brain barrier.

Probiotics (Multi-Strain)

Multi-strain probiotic supplement containing diverse beneficial bacteria to support gut microbiome health. A balanced gut microbiome is linked to improved digestion, immune function, and mental well-being. Look for formulas with clinically studied strains and high CFU counts.

Glutathione (Liposomal)

Liposomal glutathione supplement for enhanced absorption of the body's master antioxidant. Glutathione plays a critical role in detoxification, immune support, and protecting cells from oxidative stress. Liposomal delivery bypasses digestive breakdown for greater bioavailability.

Vitamin C

High-quality vitamin C supplement supporting immune function, collagen synthesis, and antioxidant defense. Essential for tissue repair and iron absorption. Liposomal forms offer enhanced bioavailability compared to standard ascorbic acid.

Zinc (Picolinate)

Zinc picolinate supplement offering superior absorption compared to other zinc forms. Supports immune function, hormone production, and wound healing. Important for maintaining testosterone levels and thyroid health, particularly in those with dietary deficiencies.

Turmeric / Curcumin

Turmeric extract standardized for curcumin content, a potent anti-inflammatory compound. Supports joint health, reduces chronic inflammation, and may protect against age-related cognitive decline. Best absorbed when paired with piperine (black pepper extract) or in a liposomal formulation.

Organ Meats (Grass-Fed)

Nutrient-dense organ meats from grass-fed animals, including liver, heart, and kidney. Organ meats are among the most bioavailable sources of B vitamins, iron, zinc, copper, and fat-soluble vitamins A and D. Available fresh or as convenient desiccated capsules for those who prefer not to cook them.

Pasture-Raised Eggs

Pasture-raised eggs are a nutrient-dense whole food providing complete protein, healthy fats, choline, and fat-soluble vitamins. Among protein sources, eggs produce one of the lowest insulin responses — making them a preferred choice in Dr. Jason Fung's protocol for meals that support metabolic health and stable blood sugar.
