Acacia gum and heart risk factors in adults

What it found

In adults with or at risk of metabolic syndrome, taking 20 g of Acacia gum daily for 12 weeks lowered blood pressure, fasting blood sugar, and calorie and carbohydrate intake, and improved bloating and bowel movements.

It did not change body weight, BMI, or blood fats.

What they found

Studies in people

Blood pressure

After 12 weeks, the gum group had lower systolic and diastolic blood pressure. The placebo group showed no change.

Blood sugar

Fasting blood sugar dropped in the gum group, but there was no difference between the gum and placebo groups at the end. HbA1c did not change in either group.

Body weight and fat

There were no changes in BMI, waist circumference, or body fat in either group. Fat-free body mass decreased in the gum group.

Diet and appetite

The gum group ate less carbohydrate and fewer calories, and ate more fiber. They also felt less hungry an hour after taking the gum compared with the placebo group.

Bloating and bowel movements

The gum group reported less bloating and better bowel movements than the placebo group. There were no big differences in abdominal pain, digestion, or nausea.

Blood fats

There were no changes in cholesterol or triglycerides in either group.

What the authors conclude

“Daily ingestion of 20 g of GA-AS for 12 weeks was shown to improve satiety and significantly reduce energy and carbohydrate intakes.”

Also in their conclusions

  • They say that daily Acacia gum improved satiety, reduced energy and carbohydrate intake, and improved blood pressure, blood sugar, and bowel movements.
  • They conclude that Acacia gum could be a useful addition to managing metabolic syndrome and may help lower the global burden of noncommunicable diseases.
  • They call for larger, long-term trials to confirm its effects and find the best dose.

How it was done

Metabolic syndrome raises the risk of heart disease and diabetes, and new ways to help manage it are needed. The authors wanted to see whether Acacia gum could improve key risk factors in people with or at risk of the condition.

They randomly assigned 80 adults aged 18 to 50 to take either 20 g of Acacia gum or a placebo (1 g pectin) daily for 12 weeks. Of these, 61 finished the study (31 in the gum group, 30 in the placebo group); 19 dropped out because they did not stick to the treatment.

What it can’t tell you

  • This was a 12-week study, so it cannot show what happens over a longer period.
  • The study cannot show whether Acacia gum prevents heart disease or diabetes, only that it changed some risk factors.
  • Because 19 people dropped out, the results may not reflect what would happen if everyone had completed the study.
