Shiitake, Mixed Nuts and Red Date Soup

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
• Walnuts · Randomized controlled trial, 305 participants · 2019
  Office systolic BP changed by -4.61 mm Hg with walnuts versus -0.59 mm Hg in controls (P=0.051); 24-hour ambulatory systolic BP difference was not significant (P=0.111). No diastolic BP changes were observed.Limitation: Only 236 of 305 participants (75%) completed the study, and the main between-group differences did not reach conventional significance.PubMed 30879358 · 2 more walnuts studies
• Red dates · Meta-analysis, 483 participants · 2025
  Jujube was associated with significantly lower BMI and triglycerides, and lower fasting blood sugar in people with type 2 diabetes. LDL and total cholesterol fell only in some subgroups. HDL, AST and ALT did not change significantly.Limitation: The authors state the overall quality of the evidence is limited, and results varied significantly by dose, treatment duration and disease type.PubMed 40399274 · 3 more red dates studies
