A new study looked into whether broccoli sprout extract (BSE) can help people who are at risk of developing diabetes lower their blood sugar.
A group of scientists led by Anders H. Rosengren did the study, which was reported in Nature Microbiology. The results show that BSE did lower blood sugar to some extent, but not as much as was hoped.
The study did, however, find an interesting link between the bacteria in the gut and how well people react to the treatment.
Why Is This Study Important?
People with prediabetes have blood sugar levels that are higher than average but not high enough to be called diabetes.
It can turn into type 2 diabetes if it is not treated, which is a dangerous disease that affects millions of people around the world.
Finding safe and effective ways to keep blood sugar under control early on could help stop diabetes and its effects.
What Is Sulforaphane and Why Broccoli Sprouts?
A natural chemical called sulforaphane can be found in broccoli and other cruciferous veggies. Sulforaphane has been shown in the past to stop the liver from making glucose, which may help lower blood sugar levels.
Because they have a lot of sulforaphane, broccoli sprouts may help people who are at risk for prediabetes.
Researchers gave people BSE, a vitamin made from broccoli sprouts, to see if it would help them keep their blood sugar in check.
How Was the Study Conducted?
The study was a randomized, double-blind, placebo-controlled trial, which means that some people got the broccoli sprout extract and others got a fake substance that had no effect.
Until the end of the study, neither the people who took part nor the experts knew who got what.
- A total of 89 participants with prediabetes took part in the trial.
- They were given either BSE (containing 150 ΞΌmol of sulforaphane) or a placebo once daily for 12 weeks.
- The main goal was to see if there was a 0.3 mmol/L reduction in fasting blood sugar in those who took BSE compared to the placebo group.
- The researchers also examined participantsβ gut bacteria to see if it affected their response to BSE.
Key Findings of the Study
1. Small but Positive Reduction in Blood Sugar
- The BSE group saw a 0.2 mmol/L reduction in fasting blood glucose, which was statistically significant but did not reach the target of 0.3 mmol/L.
- This means that while BSE had some effect, it was not strong enough to be considered a reliable treatment for prediabetes yet.
2. Some People Responded Better Than Others
- Participants with mild obesity, lower insulin resistance, and reduced insulin secretion had a better response to BSE.
- This group saw a 0.4 mmol/L reduction in blood sugar, which suggests that certain individuals might benefit more from BSE than others.
3. Gut Bacteria May Influence the Effectiveness of BSE
- The study found that people who responded well to BSE had a different gut microbiota (gut bacteria) composition.
- Specifically, these individuals had a higher number of certain Bacteroides bacteria, which help convert sulforaphane into its active form.
- The researchers also discovered a specific bacterial gene (BT2160) that might be responsible for better sulforaphane absorption.
What Do These Findings Mean?
A very important point is made by the study: treatments don’t work the same way for everyone. Due to the bacteria in their gut and the way their bodies process glucose, some people may gain more from BSE.
This means that in the future, individual treatments for prediabetes might be possible. For example, doctors might look at a person’s gut bacteria before suggesting BSE as a supplement.
Some people who took part in the study had minor stomach problems, like feeling sick, having diarrhea, or having loose stools. The good news is that there were no major side effects, so BSE is usually safe to eat.
How Can You Use This Information?
- Eating More Broccoli May Help β Even though BSE is a concentrated supplement, eating broccoli and other cruciferous veggies like Brussels sprouts, cabbage, and cauliflower may still be good for you.
- Gut Health Matters β Because bacteria in the gut affect how glucose is used, eating a lot of fiber-rich foods like yogurt, kefir, and fermented veggies may help keep your gut healthy and maybe even help you control your blood sugar.
- More Research Is Needed β The results of this study are encouraging, but more, bigger, and longer studies are needed to be sure that BSE can be generally used to treat prediabetes.
Conclusion
While broccoli sprout extract did not fully meet the study’s goals, it did show promise in helping some people. It’s interesting to learn that the bacteria in a person’s gut affect how well they respond to sulforaphane.
This could lead to more specific and effective treatments for prediabetes in the future. Adding broccoli to your diet and keeping your gut bacteria healthy could be easy things you can do right now to better control your blood sugar.
