Last week,we discussed intermittent fasting as a tool for managing blood sugar and weight. Continuing on with blood sugar balance tools, this week, I would like to share some compelling research about a relatively new twist for a popular herb.
Olive leaf extract is well-known for its anti microbial, antibacterial, antifungal, anti-inflammatory and immune system supporting qualities.
Oleuropein is considered to be the active ingredient in olive leaf extract. It is a polyphenol that has been shown to:
- help lower bad cholesterol and blood pressure
- prevent cancer
- protect against oxidative damage
- help guard against cognitive decline
- provides the distinctive flavor found in extra virgin olive oils
- More recently, scientists have shown olive leaf extract to play a role in blood glucose metabolism.
And that's just the beginning of the health benefits of olive leaf extract.
Human studies also show that supplementing with 500 mg of olive leaf extract once daily resulted in significant reductions in hemoglobin A1c levels, a predictable indicator of the average blood glucose over the previous 3-4 months.
Supplementation with Olive Leaf Extract also lowered fasting plasma insulin.
In fact, studies have shown that this herb outperforms Metformin, a common medication for insulin resistance
slowing the digestion of starches into simple sugars,
slowing the absorption of sugars in the small intestine,
and increasing the uptake of sugar across insulin receptors.
Olive leaf extract also protects tissues from the oxidative stress and damage from glycation , which occurs when glucose binds to proteins.
Finally, olive leaf extract has been shown to increase levels of other natural antioxidant systems in the body.
