From the Research

Manuka honey can be used by patients with diabetes and hypertension, but with caution and under the guidance of a healthcare provider, as it contains sugars that can affect blood glucose levels and potentially worsen metabolic issues associated with hypertension. For diabetic patients, manuka honey, like all honey, contains significant amounts of sugar (primarily fructose and glucose) that can raise blood glucose levels 1. If consumed, diabetic patients should include it in their carbohydrate counting and monitor blood glucose levels closely. A small amount (1 teaspoon, about 5g) contains approximately 17 calories and 4.5g of carbohydrates. For hypertension patients, manuka honey itself doesn't directly raise blood pressure, but its sodium content is negligible, however, excessive sugar intake over time can contribute to weight gain and metabolic issues that may worsen hypertension 2.

Key Considerations

  • The unique methylglyoxal compound in manuka honey gives it antibacterial properties, but these benefits must be weighed against the risks of blood sugar elevation 3.
  • Non-dietary applications, such as topical use for wound care, may be safer options for these patients to gain benefits without affecting blood glucose or blood pressure.
  • Some studies suggest that honey, including manuka honey, may have protective effects against metabolic syndrome, which includes diabetes and hypertension, by reducing blood sugar levels, improving lipid metabolism, and enhancing insulin sensitivity 1.
  • However, more research is needed to fully understand the effects of manuka honey on diabetic and hypertensive patients, and to determine the optimal dosage and usage guidelines 4.

Recommendations

  • Diabetic and hypertensive patients should consult their healthcare provider before using manuka honey, especially if they plan to consume it orally.
  • Patients should monitor their blood glucose levels closely if they choose to consume manuka honey, and adjust their carbohydrate counting and medication regimen as needed.
  • Topical use of manuka honey for wound care may be a safer option for diabetic and hypertensive patients, but patients should still consult their healthcare provider before using it for this purpose.
