Blueberry-enriched diet may help women’s muscle growth, repair


A new research study investigated how serum from subjects consuming a diet enriched with blueberries would affect the cells responsible for muscle growth and repair.

The emerging study, “Consumption of a blueberry-enriched diet by women for six weeks alters determinants of human muscle progenitor cell function,” was conducted at Cornell University. The results of the study were published in the Journal of Nutrition.

The study was conducted over six weeks with 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 1.5 hours after consuming the morning dose of 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.

The results showed the six-week blueberry-enriched serum obtained from the women aged 25-40 increased human muscle progenitor cell numbers in culture.

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.

There were no beneficial effects seen in the muscle progenitor cells treated with serum from participants aged 60-75 who consumed the blueberry-enriched diet, according to ht reports.
