Blueberries are in season - 5 reasons to eat them + 3 BONUS recipes


THEY ARE HERE!!! I love summer for many reasons, but one of my favorite summer snacks are blueberries. I'm lucky in that I have four large bushes in my backyard that are prolific producers. I enjoy picking in the morning before it's too hot, but the word is out among the robins, warblers, and starlings. They get up earlier than I do and munch their fair share of what feels like a very precious harvest.

Blueberries are touted as a "superfood" and one of the world's "healthiest foods" for 5 reasons.

1. Blueberries are classified as a low-glycemic index food. Blueberries GI value falls between 40-53. [1]

What's a glycemic index?

According to the Glycemic Index Foundation, "the Glycemic Index (GI) is a relative ranking of carbohydrate in foods according to how they affect blood glucose levels. Carbohydrates with a low GI value (55 or less) are more slowly digested, absorbed and metabolized and cause a lower and slower rise in blood glucose and, therefore usually, insulin levels." [2]

Why is that good for me?

Having a proper balance sugar levels is one of the body's top priorities. The body will do whatever it takes to get blood sugar back in balance. Because blueberries have a low GI, your blood sugar levels will NOT soar as a result of eating them.

2. They are a "nutrient-dense" food.

What does this mean?

You get a lot of bang for your buck when you eat blueberries because they are low in calories, carbs and sodium, and high in fiber and water content. They are an excellent source of vitamin K, vitamin C, vitamin B6, folate, potassium, copper, and manganese. Blueberries are rich in calcium, iron, magnesium, phosphorous, and zinc which help improve bone health. [3]

3. They are high in antioxidants, especially anthocyanin, which is responsible for their deep blue color.

What are antioxidants?

“Antioxidants are compounds found in food that stop or delay damage to the cells,” Lauri Wright, Ph.D., R.D., L.D., assistant professor of nutrition at the University of South Florida. They help ward off cell damage by “cleaning up” or removing waste products in our cells, called free radicals, before they can do harm. "'Free radicals' is a general term used for compounds that can attach and bind to and ultimately damage normal [cells] in the body, such as DNA,” Edward Giovannucci, M.D., professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health. Free radicals are most often implicated in cell damage that leads to cancer development. [4]

Blueberries have the highest amount of antioxidants in them compared to all the foods!

4. Blueberries may lower blood pressure

Blueberries appear to have significant benefits for people with high blood pressure, a major risk factor for stroke and heart attacks.

In one study, obese individuals at a high risk for heart disease noted a 4-6% reduction in blood pressure, after consuming 50 grams (1.7 ounces) of blueberries per day, for eight weeks (5).

Other studies have found similar effects, especially when looking at post-menopausal women (19, 20).

The implications of this are pretty impressive.

5. Blueberries boost your brain health

One of the most impressive health benefits of blueberries is its ability to enhance brain health.

There have been many studies suggesting that eating blueberries can improve memory and cognition.

In a recent 2016 study published in the European Journal of Nutrition, consuming a blueberry drink was found to improve cognitive performance compared to a placebo in 21 children. [6] Another study showed that drinking wild blueberry juice daily for 12 weeks was able to improve the memory of older adults. [7]

Although blueberries are not on the Environmental Working Group's "Dirty Dozen" list, I highly recommend organic. Conventional blueberries contain 52 pesticide chemicals. The thin skin allows the chemicals to enter the fruit's flesh more easily.

Where can I buy organic blueberries in Thurston County?

Carr's Organic Blueberry Farm located on Gull Harbor Road north of town. U-pick is $2.50/lb. They just opened on Sunday, so take your family and stock up.

If you don't eat all of them, put some in the freezer for the remainder of the year and every time you eat them, you'll have fond memories of this summer and get blueberries brilliant health benefits all year long!
