A study revealed that a diet high in antioxidants lessens the risk of type 2 diabetes. A team of researchers from Inserm carried out a study on the effect of antioxidants to the risk of type 2 diabetes. Previous studies showed that some antioxidants, such as vitamins C and E, lycophenes or flavonoids, were linked to a lower chance of developing type 2 diabetes. In the study, the researchers wanted to confirm whether overall diet is associated with the risk of diabetes.
The team used the data from the E3N study, which was comprised of around 100,000 French female participants born from 1925 to 1950, and were followed from 1990. The Inserm team followed more than 60,000 women who did not have diabetes and cardiovascular disease from 1993 to 2008. The participants answered a questionnaire about their diet at the start of the study, elaborating on at least 200 different food items. The Inserm research team calculated a score for total dietary antioxidant capacity for every participant using the data and an Italian database that provided information on the antioxidant capacity of a huge number of different foods. After that, the team looked at the links between this score and the risk of diabetes prevalence during the follow-up period.
The results revealed that an increase in antioxidant consumption of up to 15 millimoles per day (mmol/day) reduced the risk of developing diabetes; however, the effect reached a plateau in much higher levels. This level of dietary antioxidants could be done by consuming foods rich in antioxidants, such as fruits like blueberries and strawberries, nuts like walnuts and hazelnuts, dark chocolate, tea, and prunes.
The Dietary Approaches to Stop Hypertension (DASH) diet is rich in fruits, vegetables, low-fat dairy and reduced in fats and saturated fats. It was devised decades ago to reduce high blood pressure. Now, according to a study led by John Hopkins researchers, the DASH diet can significantly lower uric acid.
Uric acid is the causative agent of gout, and the DASH diet was so effective that improvements in some participants were nearly comparable to results achieved with drugs specifically prescribed to treat gout.
The findings from a randomized clinical trial could soon point the way to “an effective, safe and sustainable dietary approach” to help lower uric acid and even prevent gout flare-ups in those with mild to moderate disease, especially in those who can’t or don’t want to take gout drugs.
The Hopkins researchers said that even though symptoms of gout outbreaks — such as severe inflammation and sharp pain in the joints, like the base of the big toe — have been linked to elevated uric acid, it’s not really clear what type of diet can effectively lower uric acid and decrease the risk of flare-ups.
Following an online nutritional coaching intervention may help improve dietary habits and blood glucose control in patients with type-2 diabetes and abdominal obesity, recent research shows. French scientists examined up to 120 overweight type-2 diabetes patients aged 17 to 75 years old as part of the study. The volunteers were divided into two groups: one following an automated online coaching program, and a control group that adhered to standard nutrition advice.
The research team also monitored the participants’ dietary changes and glycosylated hemoglobin or HbA1c levels. The findings revealed that the diet index increased significantly in the online coaching group compared with the controls. Likewise, the results showed that participants in the online coaching group consumed less fat, saturated fat, sodium and empty calories. Moreover, 26 percent of participants in the nutritional coaching group lost five percent of their initial weight, compared with a measly four percent in the control group.
“Among patients with T2DM and abdominal obesity, the use of a fully automated Web-based program resulted in a significant improvement in dietary habits and favorable clinical and laboratory changes. The sustainability of these effects remains to be determined,” the researchers conclude in the Journal of Medical Internet Research online.
Nutrition coaching also shows significant efficacy in other studies
A study published in July 2016 reveals that following a structured nutritional therapy may boost disease management in patients with diabetes. Health experts at the Joslin Diabetes Center in Boston examined 108 overweight and obese adults with uncontrolled type-2 diabetes as part of research. The researchers also examined the effects of three diet interventions — traditional treatment, structured meal plan alone and structured meal plan plus weekly phone coaching — on specific diabetes markers including A1C, body weight, lipid profile and blood pressure.
