Spicing Up Diabetes Management: Mediterranean Aromatic Herbs Lead to Significant Blood Sugar Improvements
UpdatedNovember 13, 2024
The Mediterranean Diet (MedDiet) is widely recognized as a beneficial dietary pattern for managing and preventing metabolic diseases like Type 2 Diabetes (T2DM), which affects millions of people globally and comes with a host of complications and comorbidities. A recent systematic review and meta-analysis published in the journal Nutrients scrutinized the impact of aromatic herbs and spices, which are staple components of MedDiet, on the glycemic profile of individuals with T2DM.
Researchers delved into a collection of interventional studies to examine the effects of commonly used aromatic herbs and spices such as black cumin, clove, parsley, saffron, thyme, ginger, black pepper, rosemary, turmeric, basil, oregano, and cinnamon on blood sugar levels in people with T2DM.
Here's what the researchers found:
- Out of 6,958 retrieved studies, 77 were included in the qualitative synthesis, and 45 entered the meta-analysis phase.
- The analysis showed notable improvements in fasting glucose levels of subjects with T2DM who had their diets supplemented with certain spices. Cinnamon, turmeric, ginger, black cumin, and saffron were specifically highlighted for their beneficial effects.
- Among these, black cumin was the standout, demonstrating the most significant decrease in fasting glucose levels, followed by cinnamon and ginger. These supplements helped reduce blood sugar levels by approximately 17 to 27 mg/dL.
- Additionally, ginger and black cumin also reported improvements in glycated hemoglobin (HbA1c), a critical marker that reflects the average level of blood sugar over the past two to three months.
- Furthermore, cinnamon and ginger were associated with a significant decrease in insulin levels. Insulin is a hormone that regulates blood sugar levels, and its effectiveness can be hampered in conditions like T2DM.
It's crucial to note that the research specifically addresses the impact of these aromatic herbs and spices in the context of T2DM and does not make any broad claims about their general health benefits. The study provides new insights into the potential of dietary interventions with these specific herbs and spices to improve the management of T2DM and adds to the body of evidence supporting the MedDiet as a wholesome dietary approach in the context of metabolic health.
