“Galactomannans were the most effective dietary fiber for reducing the levels of HbA1c, fasting blood glucose, triglycerides, and LDL cholesterol in patients with type 2 diabetes.”

Key Findings:

Galactomannans had the highest effect on reducing the levels of HbA1c (SUCRA: 92.33%) and fasting blood glucose (SUCRA: 85.92%).
With regard to fasting insulin level, HOMA-IR, β-glucans (SUCRA: 73.45%), and psyllium (SUCRA: 96.67%) were the most effective interventions.
Galactomannans were ranked first in reducing the levels of triglycerides (SUCRA: 82.77%) and LDL cholesterol (SUCRA: 86.56%).
With regard to cholesterol and HDL cholesterol levels, xylo-oligosaccharides (SUCRA: 84.59%) and gum arabic (SUCRA: 89.06%) were the most effective fibers.

“This meta-analysis supports the health benefits of oat beta-glucan, especially for its cholesterol-lowering features, although it has some inevitable limitations.”

Key Findings:

The results were presented with the weighted mean difference (WMD) with a 95% CI.
Overall, oat beta-glucan supplementation significantly reduced levels of TC (pooled WMD = -0.24 mmol/L; 95%CI: -0.28 to -0.20 mmol/L), LDL-c (pooled WMD = -0.27 mmol/L; 95%CI: -0.35 to -0.20 mmol/L).
Furthermore, beta-glucan consumption did not show significant effects on TG (pooled WMD = -0.04 mmol/L; 95%CI: -0.13 to 0.05 mmol/L), HDL-c (pooled WMD = 0.00 mmol/L; 95%CI: -0.05 to 0.05 mmol/L).

“In conclusion, there was not a significant overall effect of beta-glucan intake on improvements of fasting glucose and insulin concentrations in hypercholesterolemic subjects.”

Key Findings:

Summary estimates of weighted mean differences (WMD) and 95% confidence interval was 0.05 mmol/L (-0.11, 0.02) for fasting glucose concentration and 0.75 pmol/L (-1.82, 3.32) for fasting insulin concentrations.
Twelve trials with a total of 603 subjects were included in the meta-analysis.
Beta-glucan consumption did not significantly affect measures of glycemic control.
In conclusion, there was not a significant overall effect of beta-glucan intake on improvements of fasting glucose and insulin concentrations in hypercholesterolemic subjects.

“However, the evidence is mixed across supplement types, and further research is needed to determine the most effective and safe approaches.”

Key Findings:

Curcumin studies presented mixed results.
Silymarin showed potential for hepatoprotective effects.
Conclusions: These findings highlight the potential of specific dietary supplements to improve various aspects of breast cancer care.

“Conclusions: Oat-based products may reduce TC and LDL-C, but have little effect on TG, HDL-C, and major cardiovascular events in patients with dyslipidemia.”

Key Findings:

Pooled estimates showed that oat-based products may result in a large reduction in LDL-C (WMD, -0.24 mmol L-1; 95% CI: -0.33, -0.15) (moderate certainty) and TC (WMD, -0.32 mmol L-1; 95% CI: -0.48, -0.17) (moderate certainty).
Compared to other diets (mainly other cereals), oat-based products probably reduce the level of LDL-C (WMD, -0.17 mmol L-1; 95% CI: -0.25, -0.08) (moderate certainty) and TC (WMD, -0.21 mmol L-1; 95% CI: -0.30, -0.12) (moderate certainty).
Both groups showed that oat-based products had little effect on HDL-C and TG (moderate certainty).
Oat-related adverse events were mostly gastrointestinal such as diarrhea, nausea, and flatulence being the most prevalent.
