Researchers found that raspberry leaf tea significantly reduced early postprandial glucose and insulin spikes when consumed with sucrose, but not glucose, in healthy adults. Teh effect is linked to ellagic acid-rich polyphenols that inhibit carbohydrate-digesting enzymes.
 and insulin at 15 (-113.9 pmol/L), 30 (-161.8 pmol/L), and 60 minutes (-139.4 pmol/L) when co-ingested with sucrose. No such effect was observed when consumed with glucose. Researchers believe this effect is mediated by ellagic acid-rich polyphenols inhibiting α-glucosidase and β-fructofuranosidase,delaying sucrose hydrolysis.<strong>Background</strong></p>
<p>Type 2 diabetes mellitus (T2DM) is a escalating global health issue, with prevalence doubling from 1990 to 2022, now affecting over 800 million people worldwide. This condition stems from inadequate insulin production or impaired insulin action, leading to chronic hyperglycemia and complications such as cardiovascular disease, neuropathy, and kidney damage, possibly necessitating amputations. </p>
<p>While medications are available, there is growing interest in safer and more affordable alternatives to support blood sugar control. Polyphenols, naturally occurring compounds found in wines, vegetables, fruits, and teas, have demonstrated promise in improving glucose metabolism by acting as antioxidants, reducing inflammation, enhancing insulin sensitivity, and slowing carbohydrate digestion, thereby blunting blood sugar spikes.Raspberry leaves, long utilized in herbal medicine, are rich in bioactive compounds including phenolic acids, ellagitannins, and flavonoids. Most research has focused on the raspberry fruit itself, with limited studies on the leaves. Previous analyses identified ellagic acid and quercetin-compounds with known diabetic and antioxidant properties- as dominant in raspberry leaves.</p>
<p><strong>The Study</strong></p>
<p>Driven by anecdotal evidence suggesting raspberry leaf tea lowers glucose levels in individuals with gestational diabetes, researchers conducted a randomized, crossover trial to investigate its potential effects on postprandial glucose and insulin responses in healthy adults. </p>
<p>Twenty-two participants (ages 18-65) with a Body Mass Index (BMI) between 18.5 and 25 kg/m² were recruited.Participants were excluded if they had conditions requiring medication, reported smoking, or any food allergies. </p>
<p>The findings offer a promising avenue for natural support in managing blood sugar levels, particularly in relation to sucrose intake, and warrant further investigation. </p>
