Shiitake Mushroom, Cloud Ear and Broccoli Stir-Fry

What studies say about the key ingredients

Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.

• Shiitake mushrooms · Randomized controlled trial · 2015
  Daily shiitake intake was associated with increased ex vivo proliferation of γδ-T and NK-T cells, higher salivary sIgA and lower serum CRP, along with changes in cytokine patterns. The comparison was before versus after intake in two dose groups.Limitation: Parallel 5 g and 10 g dose groups with no placebo or non-mushroom control. Short 4-week study in healthy young adults, with mostly ex vivo immune markers.PubMed 25866155 · 2 more shiitake mushrooms studies
• Garlic · Randomized controlled trial, 120 participants · 2016
  Gamma-delta T and NK cells proliferated better and were more activated than with placebo. The number of illnesses did not differ significantly, but cold and flu severity and missed days were lower.Limitation: Cold and flu outcomes were self-reported in daily diaries, and the dose was a concentrated extract that is not comparable to dietary garlic.PubMed 26764332 · 2 more garlic studies
• Ginger · Meta-analysis, 23 studies · 2022
  Overall, acute and delayed nausea and vomiting did not differ significantly between ginger and control groups. A subgroup taking 1 g/day or less for over four days had less acute vomiting (OR 0.30).Limitation: Clinical heterogeneity between trials required subgroup analyses, and the authors state that sufficiently large, high-quality RCTs are still needed.PubMed 36501010 · 3 more ginger studies
