Vaguely outlined phrases corresponding to “superfood” get used so much with blueberries, whose recognition has been fueled by cautious advertising and marketing. “Anytime you begin speaking about ‘superfoods’ and ‘tremendous fruits,’ it is in all probability a bit of overexaggerated,” Decker stated.

However there is no want to begin singing the blues.

If you are going to sing something, strive “Born in the united statesA.” Wild blueberries – the tiny ones, generally referred to as lowbush blueberries – are native to North America. Cultivated, or highbush, blueberries hint their roots to New Jersey, the place a farmer named Elizabeth White and a authorities botanist named Frederick Coville turned them right into a business crop in 1916.

Consumption has soared previously twenty years. Based on the U.S. Division of Agriculture, Individuals ate greater than 2 kilos of recent blueberries per individual in 2019, up from half a pound in 2003.

Blueberries are a superb supply of vitamin C. One cup of recent blueberries supplies 16% of a day’s beneficial provide for males, 19% for girls. Blueberries even have ample vitamin Ok and the mineral manganese.

If you are going to eat one thing like pancakes or muffins anyway, Decker stated, you can also make them more healthy by including blueberries to the combo. Research present, although, that baking lowers the extent of anthocyanins.

However you may simply, and tastily, work recent blueberries into meals as a part of a salad, he stated. At breakfast, toss them in your oatmeal, low-fat yogurt or whole-grain, high-fiber cereal.
