Wild Blueberries for Blood Sugar

Wild Blueberries and Healthy Blood Sugar: Pterostilbene is a Naturally Derived Compound Found in Blueberries

Wild Blueberries for Blood Sugar

Berries have been known for many years to be loaded with a large spectrum of health benefits when it comes to brain health, supporting healthy blood sugars, and neuroprotective effects. 

The best type of berries are found in the “wild” which contain a much higher nutritional profile compared to cultivated varieties. They are spread through rhizomes or underground runners which create new shoots and stems. This is in stark contrast to instead cultivated blueberries which are planted. Their smaller structure contain a more powerful amount of anthocyanin, an antioxidant, with a higher antioxidant capacity per serving.

Anthocyanin gives the berry its deep blue color and contains its own antioxidant known as pterostilbene. This nutrient is creating a big buzz among those who are into nootropics (natural cognitive enhancers) due to its brain boosting benefits.

Pterostilbene can help reduce cholesterol and can be thought of as the next resveratrol. For a 90 day timeframe it has been shown in studies to improve fasting glucose and insulin sensitivity.

The antioxidant pterostilbene is found in almonds, grapes, and especially blueberries. The bioactive in blueberries improve insulin sensitivity in obese, insulin resistant men and women.

  • Protective for cardiovascular
  • Learning and memory on brain tissue
  • Inhibits the B-catenin downstream signaling pathway

A study done by the American Society of Nutrition revealed how the bioactives in blueberries can help improve the insulin sensitivity in obese, insulin resistant men and women.

This was a 6 week preclinical study that resulted in the following:

Participants were randomized to consume either a smoothie containing 22.5 g blueberry bioactives (blueberry group, n = 15) or a smoothie of equal nutritional value without added blueberry bioactives (placebo group, n = 17) twice daily for 6 wk. Both groups were instructed to maintain their body weight by reducing ad libitum intake by an amount equal to the energy intake of the smoothies. Participants’ body weights were evaluated weekly and 3-d food records were collected at baseline, the middle, and end of the study. The mean change in insulin sensitivity improved more in the blueberry group (1.7 ± 0.5 mg⋅kg FFM−1⋅min−1) than in the placebo group (0.4 ± 0.4 mg⋅kg FFM−1⋅min−1) (P = 0.04).

The results from this study show the the serum inflammatory biomarkers and adiposity that were measured at baseline improved insulin sensitivity by the end of the study.

Pterostilbene, on the other hand, is a very important antioxidant that shows promising health benefits not only for healthy blood sugars but for antioxidant capability, anti-inflammatory, and anti-carcinogenic properties. What’s interesting is this antioxidant can be found within dietary fruit intake but it can vary on the specific amounts. For blueberries, it can vary from 99 ng to 520 ng/gram depending on the type of berry.

For purposes of longevity pterostilbene can also help be beneficial when it comes to aging and preserving cognition and motor functions well until old age.

Ending Thoughts

When it comes to your diet having a handful of wild blueberries on a daily basis is a great way to keep your blood sugars in check along with having longevity enhancing antioxidants.

If access to wild blueberries difficult to find, there is a way to get freeze dried wild blueberry in a powder or capsule form. Here is the wild blueberry powder I have been experimenting with and found to be of high quality.

Wild Blueberries has much promising health benefits not only when it comes to supporting healthy blood sugar levels but also for overall health. The pterostilbene antioxidant present in wild blueberries which has increased bioavailability compared to other stilbene compounds.
