Benefits of blueberries in women
New studies shows that consuming a diet enriched with blueberries would affect the cells responsible for muscle growth and repair.
“Consumption of a blueberry-enriched diet by women for six weeks alters determinants of human muscle progenitor cell function,” says Journal of Nutrition published by Cornell University.
The study was conducted on 22 women, 12 aged 25-40 and 10 aged 60-75. For the blueberry-enriched diet, participants consumed the equivalent of 1.75 cups of fresh blueberries/day, given as freeze-dried blueberries (19 g in the morning and 19 g in the evening), along with their regular diet. Participants were also asked to avoid other foods rich in polyphenols and anthocyanins.

Serum was obtained from the participants after eating blueberries. The researchers then investigated how the serum would affect muscle progenitor cell function through proliferation or cell number, capacity to manage oxidative stress and oxygen consumption rate or metabolism.
Results showed the six-week blueberry-enriched serum obtained from the women aged 25-40 increased human muscle progenitor cell numbers.There was also a trend toward a lower percentage of dead human muscle progenitor cells, suggesting resistance to oxidative stress, as well as increased oxygen consumption of the cells.
