Nearly one in ten people in the
US have been diagnosed with diabetes and one in three are prediabetic, a strong
indicator they will progress to full-blown diabetes in the near future without
dietary intervention. Experts indicate that by the year 2050, one half of all
American adults will fall into one of these two classifications, significantly
lowering their quality of life and lifespan.
Researchers from the Harvard
School of Public Health report the result of a study
in The American Journal of Clinical
Nutrition in support of the potent effect of flavonoids from blueberries
and other natural foods to significantly lower the risk of type 2 diabetes.
Data from prior studies has drawn a link between specific flavonoids from
dietary sources such as berries and improvement in insulin sensitivity and
signaling to improve metabolic syndrome, a series of biomarkers that lead to
diabetes.
Flavonoid-Rich Foods Including Blueberries Shield Against Metabolic Syndrome
and Diabetes
The research consisted of 70,359
women in the Nurses’ Health Study, 89,201 women in the NHS II, and 41,334 men
in the Health Professionals Follow-Up Study who were free of diabetes,
cardiovascular disease, and cancer at the outset of each study, and followed
for a period of twenty years. Higher intake of berry flavonoids (anthocyanins)
was significantly associated with a lower risk of type 2 diabetes after
adjusting for age, body weight, lifestyle and dietary factors.
The scientists found that
consumption of anthocyanin-rich foods, especially blueberries, apples and pears
was associated with a significantly lower risk of developing type 2 diabetes.
This research supports prior studies showing that blueberries significantly
boosted the production of adiponectin, the key hormone made in your white
adipose tissue that prevents your liver from developing insulin resistance,
ultimately leading to type 2 diabetes.
Eat Three to Five Servings of Fresh Berries Each Week to Lower Diabetes
Risk
Blood sugar levels spike in
response to a diet of highly refined carbohydrates, sugars, wheat products and
excess processed foods. Insulin is released by the pancreas in an effort to stabilize
blood sugar levels and usher glucose into the cells where it is needed for
energy. Over time, blood sugar spikes cause insulin to become resistant and
excess sugar remains in the blood leading to metabolic decline.
Blueberries and flavonoid rich
natural foods help regulate the action of insulin by modulating adipose
hormones to lower risk of diabetes and aid weight management issues. Consume at
least one-half cup of berries every day or use an anthocyanin-rich supplement
taken with meals to shield you from metabolic syndrome and the cellular
devastation caused by diabetes.
