Findings from a brand new mouse research recommend that elenolic acid, a pure compound present in olives, can decrease blood sugar ranges and promote weight reduction. The analysis may pave the way in which to the event of secure and cheap pure merchandise for managing weight problems and sort 2 diabetes in individuals.
The researchers discovered that after only one week, overweight mice with diabetes that got oral elenolic acid weighed considerably much less and confirmed higher blood sugar (glucose) regulation than earlier than therapy and in comparison with management overweight mice not receiving elenolic acid. The glucose-lowering impact was comparable with that of the injectable diabetic medicine liraglutide and higher than metformin, one of the crucial widespread oral medicines for sort 2 diabetes.
Way of life modifications and public well being measures have had restricted influence on the rising prevalence of weight problems, one of many prime threat components for sort 2 diabetes. Out there weight problems medication are ineffective in weight reduction upkeep, costly and/or carry potential long-term security dangers. Our purpose was to develop safer, cheaper and extra handy multi-targeting brokers that may forestall the incidence of metabolic problems and sort 2 diabetes.”

Hana Alkhalidy, PhD, a analysis scientist in Liu’s lab at Virginia Tech, will current the findings at NUTRITION 2024, the flagship annual assembly of the American Society for Vitamin held June 29–July 2 in Chicago.
Liu’s analysis staff focuses on discovering bioactive compounds from pure merchandise for diabetes administration. Beforehand, they appeared for particular molecular targets for pure compounds in elements of the physique that actively assist regulate metabolism, such because the pancreas, muscle, fats tissues and liver. Nonetheless, since pure merchandise sometimes have poor bioavailability, they determined to see if they might as an alternative goal metabolic hormone secretion within the intestine to not directly regulate metabolic perform.
For the brand new work, the researchers started by figuring out pure compounds that act on L-cells, which comprise two metabolic hormones launched throughout a meal. These hormones, known as GLP-1 and PYY, work collectively to advertise satiety and forestall overeating whereas additionally controlling blood sugar ranges and metabolism. The screening course of revealed that elenolic acid, which is present in mature olives and additional virgin olive oil, can induce the discharge of those hormones within the intestine. They have been capable of make elenolic acid by breaking down its precursor oleuropein, which is cheaper than extracting it immediately from olives.
Checks of the compound in overweight mice with diabetes revealed that mice that acquired oral elenolic acid skilled important enhancements of their metabolic well being in comparison with overweight management mice. After 4 to 5 weeks of therapy, the mice confirmed a ten.7% discount in weight problems in addition to blood sugar ranges and insulin sensitivity that have been corresponding to these of wholesome lean mice.
The elenolic acid additionally considerably decreased meals consumption and promoted weight reduction, that are related to improved circulating ranges of PYY and GLP-1 and the downregulation of agouti-related peptide within the hypothalamus. Agouti-related peptide is thought to extend consuming and weight acquire when overexpressed.
“General, the research confirmed that elenolic acid from olives has promising results on hormone launch and metabolic well being, significantly in overweight and diabetic circumstances,” stated Liu. “The compound appears to imitate the physiological circumstances of consuming to immediately promote intestine metabolic hormone secretion, which helps regulate vitality steadiness and metabolic well being.”
In line with the researchers, the focus of elenolic acid in olive oil or olives may be very low, so the advantages seen on this research would almost certainly not be gained from olive merchandise alone.
The analysis staff is now working to know how this compound creates metabolic advantages by analyzing its journey by way of the physique to learn the way it’s absorbed, distributed, metabolized and excreted. This can even reveal insights into its security for future scientific trials.
Alkhalidy will current this analysis at 3:12-3:25 p.m. CDT on Saturday, June 29, throughout the Bioactives in Well being and Illness oral session in McCormick Place (summary; presentation particulars).
