Raspberry leaf tea can offer a natural way to help manage blood sugar, according to a new study.
Research, published in Nutrientsnoted that consumption of tea after consumption of sucrose has led to a drop in blood sugar in healthy adults compared to the consumption of sucrose alone. Saccharose, commonly known as table sugar, is found in processed foods such as pastries and sodas and naturally occurs in certain fruits and vegetables.
These results arise as almost half of American adults have been diagnosed with prediabetics or diabetes, according to the centers for Disease Control and Prevention.
Research included few participants and “longer-term studies in individuals at risk of type 2 diabetes are necessary to confirm clinical relevance,” said the author of the Hind Mesfer S. Alkhudaydi, doctoral student at the University of Reading in the United Kingdom and speaker at Taif University in Saudi Arabia.
Always, The results suggest that raspberry leaf tea can support glucose control as a soft supplement and accessible to medicines or other standard treatments.
“In our essay, raspberry leaf tea was well tolerated and did not cause gastrointestinal side effects,” noted Hind.
Raspberry leaves is made from the red raspberry plant (Rubus Idaeus), the same that produces the berries.
The leaves are rich in plant compounds called polyphenols, which have antioxidant and anti-inflammatory properties. They have a long history in plant -based medicine, in particular to support menstruation and pregnancy, said Amna Haq, MS, DR, LDN, a dietitian specializing in metabolic disorders and owner of the inclusive dietitian in Chicago.
While many modern studies have examined the effects on the health of raspberries, much less focused on the leaves. According to Hind, there were “practically no clinical studies”, determining how raspberry leaves can influence blood sugar control. She and her colleagues wanted to change this.
“We were motivated by this research lake and by the presence of promising polyphenols in raspberry leaves that could influence glycemic regulations,” she said.
The researchers recruited 22 adults aged 18 to 65 without history of prediabreaking, diabetes or resistance to insulin. During four distinct sessions, participants consumed 50 grams of sucrose or glucose – another type of sugar found in foods such as grapes, corn, potatoes and energy drinks – with or without 10 grams of raspberry leaf tea.
About two hours after consumption, everyone had their blood sugar and their insulin checked.
After analysis, The researchers discovered that when people drank raspberry leaf tea after consuming sucrose, their blood sugar and their insulin levels have been considerably reduced. Glycemia dropped by 26% after 15 minutes and 44% after 30 minutes. In particular, when raspberry leaves were consumed alongside glucose, there was no significant drop in blood sugar and insulin levels.
Raspberry leaf tea used in the study has been found that 37 polyphenolic compounds contain, in particular Ellagitannins, flavonoids and phenolic acids. “The effects found in study participants are probably due to these polyphenols,” said Alkhudaydi. It is believed that they slow down the degradation of sucrose, in turn reducing the rapid peaks of blood sugar.
Before looking for raspberry leaf tea to manage your blood sugar, experts recommend consulting a health care provider, especially if you are pregnant or take medication to reduce blood hues.
It is also worth keeping in mind that The study is delivered with major warnings.
On the one hand, it was small. The researchers only tested the acute effects – not in the long term – and the participant basin included only healthy people. In addition, it is the first human study of the genre.
Thus, although raspberry leaf tea can theoretically decrease blood sugar, it is too early to know with certainty. In light of this, Jamie Baham, MS, RDN, LD, a dietitian focused on diabetes and owner of Ladybug Nutrition, said Health that The drink is worth trying in the context of a balanced diet and if you appreciate it, but not only in order to reduce blood sugar.
Haq accepted. “I would recommend incorporating a cup of raspberry leaves (brewed with a few tablespoons of leaves) alongside a meal rich in carbohydrates, but more for general pleasure,” she said.
To manage blood sugar more reliable, HAQ suggested eating meals with proteins and focusing on fiber -rich foods, like:
- Vegetables
- Legumes
- Nut
- Seeds
- Whole grains
Also avoid ultra-transformed foods and added sugars as much as possible, she added.
