Type 2 Diabetes - Do Blueberries Reduce Blood Sugar?

Blueberries are known to be highly nutritious and are one of the world’s powerful sources of antioxidants. They contain anthocyanin, the pigment that gives them their blue color (other anthocyanins may be purple or red). Anthocyanins are thought to…

  • promote heart health, and
  • decrease the risk of atherosclerosis (hardening of the arteries).

They may also help to lower the risk of certain types of cancer, although the evidence comes from small groups of people or various animals. More research is needed to determine whether they can be helpful for large groups of human beings. The molecules are antioxidants, meaning they clean up free radicals, which can cause cell death.

In July of 2017, the journal Food and Function reported on a study looking at blueberry supplementation in healthy young adults. Workers at the University of Reading in the UK supplied 17 healthy young adults with various doses of freeze-dried wild blueberry powder in the form of smoothies…

  • some smoothies had added sugar while others did not.
  • for the same amount of sugar, the participants with higher amounts of blueberry powder took longer to show increased blood sugar levels than those with lower amounts of blueberry powder.

From this information, researchers concluded anthocyanins in blueberries help to moderate the blood sugar spike after meals. They further suggested more research on the berries could find just how they work, possibly helping with Type 2 diabetes and loss of memory.

One cup of blueberries, with 84 calories, supplies the following percentage of the daily need for…

  • Vitamin A… 2
  • Vitamin C… 24
  • Thiamin… 4
  • Riboflavin… 4
  • Vitamin B6… 4
  • Niacin… 3
  • Folate… 2
  • Pantothenic acid… 2
  • Calcium… 1
  • Iron… 2

Why not give making a blueberry salad with raspberries a go? Or cut whole peaches in half and fill each half with blueberries for a snack or dessert. Toss some blueberries over oatmeal for some added flavor and color.

Blueberry bushes grow in a wide variety of climates, so ask your local nursery grower for the kind best suited to your area…

  • they prefer an acid pH of 4.5 to 5.5 and grow well if peat moss is added to the soil.
  • plant more than one variety in your garden for cross-pollination and healthy fruit.

Plants must have good drainage. Work a volume of soil one foot deep and 2 ½ feet in diameter. Provide 1 to 2 inches of water weekly. Cut off the flower buds during the first two years to allow plants to grow. Pick your berries 3 days after they turn blue. Enjoy!
