Maitake
Used in multiple Longevity Diet dishes. Maitake mushrooms are the top food source of vitamin D among mushrooms (786 IU per cup raw, 196.5% DV), the highest of any non-animal food when UV-exposed.
Why It Matters for Longevity
Used in multiple Longevity Diet dishes. Maitake mushrooms are the top food source of vitamin D among mushrooms (786 IU per cup raw, 196.5% DV), the highest of any non-animal food when UV-exposed. Mushrooms synthesize vitamin D2 (ergocalciferol) upon UV light exposure, analogous to human skin producing vitamin D3; maitake's ergosterol-rich structure makes it the most potent dietary vitamin D source among mushrooms.. Maitake mushrooms contain beta-glucan polysaccharides (D-fraction) that stimulate NK cell and macrophage activity, demonstrating significant immunomodulatory effects in human cancer patients and healthy volunteers. (PMID 23402898) (PubMed) Maitake D-fraction (beta-glucan extract) inhibits tumor growth in mouse models and enhances the efficacy of standard chemotherapy; supports inclusion of maitake in cancer-preventive longevity diets. (PMID 19193149) (PubMed)
How to Use It
Pairs well with olive oil, garlic, lemon. Use as a mushroom in your daily meals according to the Longevity Diet guidelines.

Synergies
- Olive Oil (synergy): Fat in olive oil significantly enhances absorption of fat-soluble vitamin D2 from maitake — always sauté maitake in olive oil or dress with olive oil - Herring (complement): Herring provides vitamin D3 while maitake provides D2; together they cover both major dietary forms of vitamin D, supporting more complete vitamin D status - Garlic (complement): Classic culinary pairing in Italian longevity cooking; garlic's allicin and maitake's beta-glucans provide complementary immunomodulatory effects
Flavor Profile
Taste: earthy, savory, umami-rich, slightly peppery. Aroma: forest floor, earthy, woodsy, rich umami. Texture: frilly and delicate raw, tender when cooked, slightly chewy. Category: culinary and medicinal mushroom.
The Science
- PubMed: Maitake mushrooms contain beta-glucan polysaccharides (D-fraction) that stimulate NK cell and macrophage activity, demonstrating significant immunomodulatory effects in human cancer patients and healthy volunteers. (PMID 23402898) - PubMed: Maitake D-fraction (beta-glucan extract) inhibits tumor growth in mouse models and enhances the efficacy of standard chemotherapy; supports inclusion of maitake in cancer-preventive longevity diets. (PMID 19193149) - PubMed: UV-exposed maitake mushrooms (placed gills-up in sunlight for 1–2 hours) generate sufficient vitamin D2 to meet or exceed daily requirements; equivalent to 9 mcg (360 IU) per gram dry weight after sun exposure. (PMID 25866155) - Examine.com: Maitake beta-glucans activate innate immune pathways (TLR2, Dectin-1 receptors), reduce blood glucose, and demonstrate anti-tumor activity; vitamin D2 from sun-exposed maitake is bioavailable and raises serum 25(OH)D2 comparably to supplemental vitamin D2. - Book claim (high confidence): Used in multiple Longevity Diet dishes.

Key Nutrients
| Nutrient | Per 100g | Notes |
|---|---|---|
| Vitamin D2 (ergocalciferol) | ~786 IU (UV-exposed, raw) | UV-exposed maitake is the richest plant-kingdom vitamin D source; cooking reduces content by ~50% — use raw or lightly sautéed; gills-up sun exposure for 30–60 min maximizes D2 |
| Beta-glucans (D-fraction) | ~15–30 g (dry weight basis) | Partially digested; activate pattern recognition receptors on immune cells; not destroyed by cooking |
| Ergothioneine | ~1.3 mg | Unique thiol antioxidant synthesized only by fungi; stable to cooking; accumulates in high-stress tissues (liver, kidney, brain) |
| Potassium | ~210 mg (raw) | Well-bioavailable; supports blood pressure regulation |
| Copper | ~0.3 mg (raw) | Mushrooms are good copper sources; essential for immune cell function and antioxidant enzymes |
