A brand new analysis examine investigated how serum from topics consuming a diet enriched with blueberries would have an effect on the cells chargeable for muscle progress and restore.
The rising examine, “Consumption of a blueberry-enriched diet by women for six weeks alters determinants of human muscle progenitor cell function,” was carried out at Cornell University. The outcomes of the examine had been revealed within the Journal of Nutrition.
The examine was carried out over six weeks with 22 girls, 12 aged 25-40 and 10 aged 60-75. For the blueberry-enriched diet, contributors consumed the equal of 1.75 cups of contemporary blueberries/day, given as freeze-dried blueberries (19 g within the morning and 19 g within the night), together with their common diet. Participants had been additionally requested to keep away from different meals wealthy in polyphenols and anthocyanins.
Serum was obtained from the contributors 1.5 hours after consuming the morning dose of blueberries. The researchers then investigated how the serum would have an effect on muscle progenitor cell perform by way of proliferation or cell quantity, capability to handle oxidative stress and oxygen consumption price or metabolism.
The outcomes confirmed the six-week blueberry-enriched serum obtained from the ladies aged 25-40 elevated human muscle progenitor cell numbers in tradition. There was additionally a pattern towards a decrease proportion of lifeless human muscle progenitor cells, suggesting resistance to oxidative stress, in addition to elevated oxygen consumption of the cells. There had been no useful results seen within the muscle progenitor cells handled with serum from contributors aged 60-75 who consumed the blueberry-enriched diet.
“The consequences associated with the deterioration of skeletal muscle are a loss of mobility, decreased quality of life, and ultimately, loss of independence. Currently, research on dietary interventions to support skeletal muscle regeneration in humans is limited. This preliminary study of muscle progenitor cell function paves the way for future studies to develop clinical interventions,” stated Anna Thalacker-Mercer, Ph.D., the examine’s lead investigator. “While the results cannot be generalised to all populations, this study is an important step in translating findings from cell culture and rodent studies to a potential dietary therapy for improving muscle regeneration after injury and during the ageing process.”
According to the Centers for Disease Control and Prevention (CDC), muscular tissues lose energy, flexibility, and endurance over time. Muscle mass decreases three to 5 per cent each decade after 30 years of age, and that price will increase over age 60. Therefore, methods to enhance muscle progenitor cell proliferation and decrease oxidative stress may additionally profit muscle regeneration through the ageing course of.
Research on the position that blueberries may play in selling good well being is ongoing throughout a number of areas, together with cardiovascular well being, diabetes administration, mind well being, train and the intestine microbiome.
