A 10-week study of 51 overweight adults found that drinking a phenol-rich sorghum beverage daily improved heart health markers including HDL cholesterol and triglycerides, enhanced insulin control, and promoted healthier gut bacteria—while the control group’s heart health markers worsened. According to Gram Research analysis, the sorghum group maintained muscle mass during weight loss while the control group gained body fat, suggesting the beverage’s natural plant compounds provide metabolic benefits beyond simple calorie reduction.
A Gram Research analysis of a new study found that drinking a special beverage made from sorghum grain for 10 weeks helped adults with extra weight improve their heart health and gut bacteria. The drink is packed with natural plant compounds called phenols that act like antioxidants—think of them as tiny bodyguards protecting your cells from damage. When people drank this sorghum beverage daily while eating a healthy diet with fewer calories, they had better cholesterol levels, lower blood sugar control problems, and healthier gut bacteria compared to people who drank a regular beverage. The results suggest this simple drink could be a helpful addition to weight management and heart health efforts.
Key Statistics
A 2026 randomized controlled trial of 51 overweight adults found that consuming a phenol-rich sorghum beverage for 10 weeks increased HDL cholesterol (good cholesterol) and decreased triglycerides compared to a control group, while the control group’s body fat percentage increased.
According to research reviewed by Gram, the sorghum beverage group showed improved insulin control with decreased HOMA-IR scores and better blood sugar handling (TyG index) after 10 weeks, while also increasing beneficial acetic acid in their gut bacteria.
A 2026 study of 51 adults found that the sorghum beverage group maintained their muscle mass during weight loss while the control group gained body fat percentage over the same 10-week period on an identical calorie-restricted diet.
Research showed that participants drinking the sorghum beverage had higher blood levels of phenolic compounds like trans-caffeic acid and naringenin, with increased total plasma antioxidant capacity protecting against cellular damage.
The Quick Take
- What they studied: Whether a special drink made from sorghum grain with lots of natural plant compounds could improve heart health, gut bacteria, and weight management in adults who are overweight.
- Who participated: 51 adults (both men and women) who were overweight. Half drank the sorghum beverage daily, and half drank a regular control beverage. Everyone also followed a healthy eating plan with fewer calories for 10 weeks.
- Key finding: Adults drinking the sorghum beverage improved their cholesterol levels, insulin control, and gut bacteria health compared to the control group, while maintaining their muscle mass during weight loss.
- What it means for you: If you’re trying to manage your weight and improve your heart health, adding a sorghum-based beverage to your routine might help—but it works best when combined with healthy eating habits. Talk to your doctor before making major dietary changes, especially if you have diabetes or heart conditions.
The Research Details
This was a randomized controlled trial, which is one of the strongest types of scientific studies. Researchers divided 51 overweight adults into two groups: one group drank a special sorghum beverage daily, while the other group drank a regular control beverage. Neither group knew which beverage was which (called “single-blind”), which helps prevent bias. Everyone followed the same healthy eating plan with 500 fewer calories per day for 10 weeks.
The sorghum beverage was made from a special type of grain called BRS 305 sorghum that had been processed to keep lots of natural plant compounds called phenols. These phenols include flavonoids and phenolic acids—the same healthy compounds found in berries and green tea. Researchers measured many things before and after the study, including blood work, body composition, gut bacteria markers, and stool samples.
This study design is important because it lets researchers compare two similar groups where the only real difference is the beverage they drink. This helps prove that any improvements came from the sorghum drink itself, not from other factors.
The randomized, controlled design is crucial because it eliminates many sources of error. By having a control group that didn’t get the sorghum beverage, researchers could see what changes happened naturally during weight loss versus what the sorghum specifically caused. The single-blind design (where participants didn’t know which beverage they were drinking) prevents people from expecting benefits and imagining they feel better—a powerful effect called the placebo effect.
This study has several strengths: it included a control group for comparison, used a 10-week timeframe long enough to see real changes, and measured many different health markers (blood work, gut bacteria, body composition). The study was published in a respected nutrition journal. However, the sample size of 51 people is relatively small, and the study only lasted 10 weeks, so we don’t know if benefits continue longer. The study was also single-blind rather than double-blind (where neither researchers nor participants would know who got what), which is slightly less rigorous.
What the Results Show
The sorghum beverage group showed several important improvements. Their blood cholesterol improved—specifically, they increased their HDL cholesterol (the “good” kind) and decreased their Castelli Index (a measure of heart disease risk). They also had better insulin control, meaning their bodies handled blood sugar more efficiently. Their triglycerides (a type of fat in the blood linked to heart disease) decreased, and their HOMA-IR score improved, which measures how well insulin is working.
One of the most interesting findings was what happened in their gut. The sorghum group’s stool became less acidic (lower pH), and they had more acetic acid in their stool—a sign of healthier gut bacteria. Acetic acid is produced by good bacteria and is linked to better overall health.
The sorghum group also showed better antioxidant protection. Their blood had higher levels of natural compounds that protect cells from damage, and markers of oxidative stress (cellular damage) decreased. Importantly, while the control group gained body fat during the study, the sorghum group maintained their muscle mass while losing weight—a much healthier outcome.
The control group, by contrast, actually got worse in some ways. They increased their body fat percentage and decreased their nitric oxide levels (important for blood vessel health) during the same 10-week period.
The researchers found that the sorghum beverage contained diverse phenolic compounds—natural plant chemicals with antioxidant properties. After drinking the beverage, participants had higher blood levels of specific phenols like trans-caffeic acid and naringenin, showing that these beneficial compounds were actually being absorbed and used by the body. The beverage also improved the TyG index, another marker of metabolic health related to insulin resistance. These secondary findings suggest the sorghum’s benefits come from its natural plant compounds being absorbed and working throughout the body.
This research builds on previous studies showing that whole grains and plant-based beverages can improve heart health. However, this is one of the first studies specifically examining this particular sorghum variety (BRS 305) and its effects on gut bacteria markers. The findings align with what we know about phenol-rich foods improving antioxidant status and heart health markers, but the specific combination of benefits—improved cholesterol, better insulin control, and healthier gut bacteria—makes this study a valuable addition to the research.
The study only lasted 10 weeks, so we don’t know if benefits continue longer or if people can stick with drinking the beverage long-term. The sample size of 51 people is relatively small—larger studies would give us more confidence in the results. The study was single-blind rather than double-blind, meaning researchers knew who was getting the sorghum beverage, which could introduce subtle bias. The study also didn’t track what participants ate outside the controlled meals, so diet variations could have affected results. Finally, all participants were overweight adults, so these results may not apply to people of normal weight or different ages.
The Bottom Line
Based on this research, a sorghum-based beverage may be a helpful addition to a weight management and heart health plan, particularly for overweight adults. However, the evidence is moderate strength because this is a single 10-week study with a small sample size. The beverage appears most effective when combined with a healthy, calorie-controlled diet—the beverage alone won’t produce these benefits. More research is needed before making strong recommendations, but the results are promising enough to discuss with your healthcare provider.
This research is most relevant for overweight or obese adults interested in improving their heart health and managing weight. People with insulin resistance, prediabetes, or high cholesterol might find this particularly interesting. However, people with sorghum allergies should avoid this beverage. If you have diabetes, heart disease, or take medications affecting blood sugar or cholesterol, talk to your doctor before adding this beverage to your routine, as it may interact with your treatment.
In this study, improvements appeared over 10 weeks. You likely wouldn’t see dramatic changes in the first week or two. Most benefits emerged gradually over the full 10-week period while participants also followed a healthy eating plan. Realistic expectations: noticeable improvements in blood work markers within 6-10 weeks, though individual results vary. Remember, this beverage works best as part of an overall healthy lifestyle, not as a standalone solution.
Frequently Asked Questions
Can sorghum beverage help me lose weight and improve my cholesterol?
A 2026 study found that sorghum beverage combined with a calorie-controlled diet improved cholesterol levels and insulin control in overweight adults over 10 weeks. The beverage alone won’t cause weight loss, but it may enhance results when paired with healthy eating habits.
What are phenols and why do they matter in this sorghum drink?
Phenols are natural plant compounds with antioxidant properties that protect your cells from damage. The sorghum beverage contains phenolic acids, flavonoids, and tannins—the same beneficial compounds in berries and green tea—which your body absorbs and uses for heart and metabolic health.
How long do I need to drink sorghum beverage to see health benefits?
This study showed improvements over 10 weeks when combined with a healthy diet. Most participants likely saw gradual changes in blood work markers within 6-10 weeks rather than immediate results. Individual timelines vary based on starting health status and diet consistency.
Is sorghum beverage safe for people with diabetes or heart disease?
While the study showed positive effects on insulin control and cholesterol, people with diabetes or heart disease should consult their doctor before adding sorghum beverage to their routine, as it may interact with medications or affect blood sugar management.
Why did the control group’s health markers get worse during the study?
The control group drank a regular beverage without the beneficial phenolic compounds while following the same calorie-restricted diet. Without the sorghum’s antioxidants and metabolic benefits, their body composition and heart health markers declined despite calorie reduction, suggesting the sorghum provides specific protective effects.
