Diet soft drink is associated with increased odds of proliferative diabetic retinopathy

The challenge of dietary management in soft drink consumption and its oral and systemic repercussions

Background:Soft drinks are drinks high in sugar and acidity, but low in nutritional benefits. Despite its great popularity, its consumption is alerted due to the numerous systemic harm caused. Aim:This work aims to provide information and critically review the literature on the risk of soft drink consumption in an integrative view with nutritional, dental, and medical aspects. Methods:A search was carried out based on the identification of the theme, determination of inclusion and exclusion criteria, selection of databases for research and, finally, the reading, interpretation, and discussion of the selected sources. A search was conducted using the keywords: "soft drinks" AND "obesity" OR "dental erosion" OR "diabetes" OR "hypertension" OR "mental health" OR "multimorbidities" in databases PubMed, SciELO, and LILACS between 2017 and 2022. Results:Seventy-six studies were included in the article after the qualitative synthesis. Conclusion:We conclude that the high consumption of soft drinks is associated with oral and general diseases. Therefore, a multi-professional approach to guide patients to moderate the consumption of these beverages is extremely important.

Dietary Intake and Diabetic Retinopathy: A Systematic Review of the Literature

Diabetic retinopathy (DR) is a common microvascular complication of diabetes mellitus. The evidence connecting dietary intake and DR is emerging, but uncertain. We conducted a systematic review to comprehensively summarize the current understanding of the associations between dietary consumption, DR and diabetic macular edema (DME). We systematically searched PubMed, Embase, Medline, and the Cochrane Central Register of Controlled Trials between January 1967 to May 2022 for all studies investigating the effect of diet on DR and DME. Of the 4962 articles initially identified, 54 relevant articles were retained. Our review found that higher intakes of fruits, vegetables, dietary fibers, fish, a Mediterranean diet, oleic acid, and tea were found to have a protective effect against DR. Conversely, high intakes of diet soda, caloric intake, rice, and choline were associated with a higher risk of DR. No association was seen between vitamin C, riboflavin, vitamin D, and milk and DR. Only one study in our review assessed dietary intake and DME and found a risk of high sodium intake for DME progression. Therefore, the general recommendation for nutritional counseling to manage diabetes may be beneficial to prevent DR risk, but prospective studies in diverse diabetic populations are needed to confirm our findings and expand clinical guidelines for DR management.

Diet Sugar-Free Carbonated Soda Beverage, Non-Caloric Flavors Consumption, and Diabetic Retinopathy: Any Linkage

PURPOSE

Assessing diabetic retinopathy (DR) risk factors and daily nutrition habits are vital for prevention. This study aims to evaluate the relationship between diet soda cans, non-nutritive sweetener consumption, and diabetic retinopathy.

PATIENTS AND METHODS

A cross-sectional study was conducted among 200 patients attending a diabetes center in Tabuk City, Saudi Arabia, from September 2019 to July 2020. A structured questionnaire was used to collect patients' demographic factors, and DR risk factors including the use of diet soda, non-nutritive sweeteners, and exercise habits. Dilated fundus eye examination was done to detect any diabetic retinopathy. A blood sample was taken for measuring glycated hemoglobin to assess the degree of glycemic control.

RESULTS

The participant's age was 50.74 ±13.51 years, and the duration since the diagnosis of diabetes was 9.99 ±6.97 years, body mass index was 27.28 ±4.68, and HbA1c %, 8.50 ±1.61), the patients used to consume 1.31 ±1.57 diet soda cans/week, and 1.06±1.39 artificial sweeteners/sachet/day. DR was found in 33%. Diet sugar-free carbonated soda beverage was associated with poor glycemic control and retinopathy, while non-caloric flavor consumption was associated with obesity (P-value<0.05). No association was evident regarding other factors (P-value>0.05).

CONCLUSION

Diet sugar-free carbonated soda beverage was associated with higher HbA1c and retinopathy, while non-caloric flavor consumption was associated with obesity. No association was evident regarding other factors. Further larger multicenter studies are needed.

Reversal of diabetic tractional retinal detachment attributed to keto diet

A 40-year-old woman, known type 2 diabetes mellitus, obese (100 kg), on insulin (80 units), was under treatment for unstable proliferative diabetic retinopathy with extramacular tractional retinal detachment (TRD) in the left eye. At 1-year follow-up, she developed progression of TRD involving the macula in the left eye for which she was advised surgery. She did not follow-up for 6 months during which time she had adopted a coconut oil-rich ketogenic diet. She reported losing 25 kg body weight along with reversal of diabetes (Glycosylated Haemglobin (HbA1C) of 5.3% without insulin) in the interim. During this 2-year follow-up visit, it was found that there was complete resolution of macular detachment due to TRD in the left eye with stable vision. This was attributed to the impactful ketogenic diet.

Impact of food pattern on glycemic control among type 2 diabetic patients: a cross-sectional study in the United Arab Emirates

BACKGROUND

Optimum nutrition has an integral role in glycemic control of diabetic patients. In this study, we intend to explore the frequency of food group/item consumption and its association with the risk of poor glycemic control (Hb_A1c >7%) among type 2 diabetes (T2D) patients in the United Arab Emirates (UAE), since there are no data available in this region.

METHODS

In this retrospective cross-sectional study, data on frequency of food group/item consumption of 843 T2D patients aged ≥18 years were collected from records documented by dietitians in a tertiary care center in the UAE.

RESULTS

The trends of food consumption demonstrate that one-third of the participants consumed all five major food groups, and 10% adhered to the recommended "MyPlate" meal pattern with the optimum mix of food groups. Univariate analysis indicated that participants who adhered to the MyPlate meal pattern presented lower Hb_A1c (β=-0.78, 95% CI -1.22, -0.25; P<0.01). Daily intake of fresh fruit was shown to be protective (β=-0.64, 95% CI -1.26, -0.04; P=0.04) while fruit juice intake >1 time/day increased the risk of poor glycemic control (β=1.53, 95% CI 0.72, 2.35; P<0.001). Multiple logistic regression models (area under the receiver operating characteristics curve =0.67) showed consumption of fizzy drinks and fast food ≥1 time/week increased the odds of poor glycemic control by 2.05 (95% CI 1.16, 3.68; P=0.01) and 1.83 (95% CI 1.02, 3.3 P=0.04), respectively, while fresh fruit consumption indicated a clinically relevant protective effect  (OR=0.65, 95% CI 0.23, 1.79; P=0.4).

CONCLUSION

Consuming food such as fizzy drinks and fast food ≥1 time/week could possibly serve as an independent predictor for poor glycemic control, while fresh fruit could have a protective effect on glycemic control among T2D patients.Clinical Trial Registry: ClinicalTrials.gov Identifier: NCT03388229.
