- New analysis has revealed that rising the consumption of flavonoid-rich meals can considerably scale back the danger of creating kind 2 diabetes.
- This type of diabetes is a rising public well being concern, affecting over 400 million folks worldwide and contributing to over 1 million deaths yearly, in keeping with the World Well being Group (WHO).
- Researchers analysed knowledge from 113,097 individuals within the UK Biobank, discovering {that a} food plan excessive in flavonoids, notably from meals like berries, apples and tea, is linked to improved insulin sensitivity and lowered diabetes danger.
A brand new research, revealed in
Adopting a food plan wealthy in plant-based meals is already identified to lower the danger of kind 2 diabetes. Nonetheless, crops are ample in numerous polyphenolic compounds that differ of their bioavailability and bioactivity.
Flavonoids, a class of polyphenolic compounds, are divided into six primary subclasses: flavanones, flavones, flavan-3-ols, flavonols, anthocyanins, and isoflavones.
There may be some proof to recommend {that a} larger consumption of flavonoids could result in
The brand new research concerned 113,097 individuals from the UK Biobank, a large-scale, population-based cohort research that recruited over 500,000 adults within the UK between 2006 and 2010.
The individuals’ flavonoid consumption was assessed by two or extra 24-hour dietary surveys, which have been analysed utilizing the USA Division of Agriculture databases.
Ten flavonoid-rich meals have been chosen primarily based on common day by day consumption. A Flavodiet Rating (FDS) was calculated by summing the servings of those ten meals.
Statistical analyses, accounting for potential confounders, have been carried out to evaluate the connection between dietary flavonoid consumption and the event of kind 2 diabetes.
The research discovered that larger consumption of flavonoid-rich meals was extra frequent amongst feminine individuals, older people, those that have been bodily lively and people with larger academic ranges.
The common day by day flavonoid consumption was 805.7 milligrams. Among the many flavonoid subclasses, polymers — together with proanthocyanidins — and flavan-3-ols have been essentially the most important contributors, accounting for 67% and 22% of the overall consumption, respectively.
Tea was the first supply for these subclasses. Flavones, primarily derived from peppers, contribute the least to complete flavonoid consumption.
When analyzing the affiliation between flavonoid consumption and the danger of creating kind 2 diabetes, the research adjusted for individuals’ demographic and way of life traits.
It discovered {that a} larger Flavodiet Rating (FDS) — equal to consuming six servings of flavonoid-rich meals per day — was linked to a 28% decrease danger of creating kind 2 diabetes in comparison with a decrease FDS of 1 serving per day.
The research discovered that every further day by day serving of flavonoid-rich meals reduces diabetes danger by 6%, 4 servings of black or inexperienced tea per day have been linked to a 21% decrease danger, 1 serving a day of berries was related to a 15% decrease diabetes danger, and 1 serving per day of apples was related to a 12% decrease danger.
The evaluation recognized physique mass index (BMI), insulin-like progress issue 1 (IGF-1), C-reactive protein, cystatin C, urate, gamma-glutamyl transferase (GGT) and alanine aminotransferase (ALT) as potential mediators.
The findings recommend {that a} flavonoid-rich food plan positively impacts weight administration, glucose metabolism, irritation and kidney and liver features, contributing to the lowered danger of kind 2 diabetes.
Flavonoids, particularly anthocyanins, flavan-3-ols, and flavonols, improve insulin secretion and signalling, and enhance glucose transport and metabolism.
Nonetheless, the research’s findings is probably not generalisable to non-European populations because the research inhabitants consisted of middle-aged British adults.
Two consultants, not concerned on this analysis, spoke to Medical Information At this time about its findings.
Megan Hilbert, RDN, a registered dietitian specialising in intestine well being diet and the gut-brain axis, informed MNT that “these findings assist to substantiate loads of what we perceive in regards to the pathophysiology of kind 2 diabetes.”
“This research confirms flavonoids affect on this, attributable to flavonoids’ potential to assist scale back irritation and even assist these with excessive intakes preserve a wholesome weight,” she defined.
“These findings present that flavonoid consumption will help decrease extra adipose tissue which could be pro-inflammatory, in addition to scale back adipose tissue that surrounds clean muscle tissue, permitting for extra blood glucose to be absorbed by stated muslce cells,” Hilbert added.
“These modifications assist permit the physique to course of blood sugars extra successfully, resulting in a lowered danger in creating kind 2 diabetes,” she stated.
“What I actually loved about this research is that completely different flavonoids have been in contrast and the information confirmed sure flavonoids to have a bigger affect on reductions in diabetes, and sure meals specifically appeared to have a extra protecting impact than others. These particular findings can play an enormous position in educating sufferers on dietary suggestions.”

Kelsey Costa, MS, RDN, a registered dietitian nutritionist and founding father of Dietitian Insights, agreed, noting that “given flavonoids’ well-documented
In response to Costa, flavonoids’ position in blood sugar management may additionally clarify their hyperlink to decrease diabetes danger:
“Flavonoids could assist stop and handle diabetes and its issues by regulating glucose metabolism, enhancing insulin signaling and secretion and liver enzyme exercise, lowering oxidative stress, and optimizing lipid profiles, which collectively enhance weight problems, blood sugar ranges, continual irritation, and kidney and liver perform.”
“Nonetheless, the massive UK Biobank cohort and substantial follow-up add additional proof to assist flavonoids’ protecting position in stopping kind 2 diabetes,” she cautioned.
As well as, she highlighted that the “scientific neighborhood continues to uncover the dangerous results of alcohol consumption, together with its affiliation with systemic irritation, weight achieve, and disturbances in fats metabolism, which may in the end contribute to the event of kind 2 diabetes.”
“Subsequently, I’m happy that this research accounted for the overall alcohol consumption of individuals when inspecting the connection between flavonoid consumption and sort 2 diabetes danger of their preliminary evaluation after which reassessed the information by excluding crimson wine from the flavonoid food plan rating to find out if the outcomes would differ,” Costa informed us.
She additional famous that “
