Celery and Shiitake Pork Rolls

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
