Risk factors, prevention, and treatment of type 2 diabetes
International Journal of Health Sciences (IJHS), 2022
Recent evidence gleaned from forthcoming experimental research and clinical examinations lends credence to the idea that certain dietary patterns, foods, and minerals can play a part in lowering the risk of developing type 2 diabetes and keeping the condition under control. The quality of the nutritive fats and carbs that are ingested is far more essential than the amount of these nutrients that are taken in. It has been demonstrated that diets that are high in legumes, whole grains, nuts, fruits and vegetables and low in red meats, refined grains, and beverages lessen the incidence of diabetes and better glycaemic control and blood lipids in diabetics. Diets that are high in beverages and red meats increase the risk of developing diabetes. Numerous dietary patterns, i.e., the Mediterranean diet, diets with a low glycaemic index, diets with moderately low carbs, and veggie diets, are all able to be adapted to individual and cultural food preferences while still meeting the 8823 necessary calorie requirements for weight management, diabetes prevention and management, and other related health goals. Significant progress has been made in evolving and putting into practise evidence-centred diet recommendations in industrialised nations, but to minimise regional imbalances, concerted global actions and policies are required.
Relationship between dietary patterns and incidence of type 2 diabetes
International Journal of Preventive Medicine, 2019
Introduction: Increasing rate of type 2 diabetes (T2D) prevalence during the recent years has caused concern about significant risks for the public health. Dietary patterns have recently attracted great attention in the evaluation of the relationship between diet and health. In the present study, we investigated the relationship between the major identified dietary patterns and T2D. Methods: In this matched case-control study, 315 individuals (125 newly diagnosed cases and 190 controls); 18-60 years of age were selected. A valid semiquantitative food frequency questionnaire was used to collect dietary intakes of individuals. Anthropometric characteristics and blood pressure were measured with standard instructions and body mass index and waist to hip ratio were calculated. Factor analysis was used to identify major dietary patterns. The relationship between major food patterns and T2D was assessed by logistic regression analysis. Results: Two dietary patterns were identified: healthy and Western dietary patterns. The second tertile of the healthy dietary pattern had significantly association with decreased risk of T2D in the crude model (Odds ratios [OR]: 0.51, 95% Confidence interval [CI]: 0.29-0.9; P for trend = 0.018), Model II (OR: 0.5, 95% CI: 0.27-0.9; P for trend = 0.019), and Model III (OR: 0.56, 95% CI: 0.23-1.4 P for trend = 0.048). The inverse association of the second tertile of Western dietary pattern score with the T2D was significant in crude (OR: 9.25, 95% CI: 4.95-17.4; P for trend <0.001) and multivariable-adjusted model (OR: 16.65, 95% CI: 2.99-92.84; P for trend <0001). Conclusions: Our study found an inverse relationship between adherence of healthy pattern and direct association with Western dietary pattern and the risk of T2D.
Effect of Dietary Factors on Incidence of Type 2 Diabetes: A Systematic Review of Cohort Studies
Journal of Nutritional Science and Vitaminology, 2005
We systematically reviewed cohort studies on the effect of nutrient and food intake (except for alcohol) on the incidence of type 2 diabetes , which had been published in English as of May 2004. Using the MEDLINE (PubMed) database as well as reference lists of searched papers, 15 individual cohort studies (a total of 31 papers) were identified. The number of subjects (n=895-85,060), follow-up length (5 .9-23y), the number of diabetes cases (n=74-4,085), dietary assessment method used (simple food questionnaire , food fre quency questionnaire, food frequency interview, diet history interview, and 24-h recall), and method of case ascertainment (questionnaire , oral glucose tolerance test, fasting glu cose level, death certificate, and nationwide registry) varied among studies. For nutrients, intakes of vegetable fat, polyunsaturated fatty acid , dietary fiber (particularly cereal fiber), magnesium, and caffeine were significantly inversely correlated and intakes of trans fatty acid and heme-iron, glycemic index, and glycemic load were significantly positively corre lated with the incidence of type 2 diabetes in several papers. For foods and food groups, several papers showed significantly decreased risk for type 2 diabetes with the higher con sumption of grain (particularly whole grain) and coffee, and significantly increased risk with processed meat consumption. Because all the studies were carried out in Western countries, however, research in non-Western countries including Japan is needed .

AIM: To identify dietary patterns among apparently healthy individuals and to determine their long-term effect on diabetes incidence. METHODS: During 2001-2002, a random sample of 3,042 men and women (18-89 years old), living in greater Athens, was randomly selected to participate in the study. During 2011-2012, the 10-year follow-up was performed in 2,583 participants (15% drop-out rate). After excluding participants with diabetes at baseline and those for whom no information on diabetes status was available at follow-up, the working sample consisted of 1,485 participants. Dietary habits were assessed by means of a validated semiquantitative, food frequency questionnaire. Factor analysis was performed to extract dietary patterns from 18 food groups. RESULTS: Diabetes diagnosis at follow-up was made in 191 participants, yielding an incidence rate of 12.9%. Six factors (i.e. dietary patterns) were identified that explained 54% of the variation in consumption. After adjusting for major confounders, and stratification by age-group, logistic regression revealed that the most healthful pattern consisted of the consumption of fruits, vegetables, legumes, bread, rusk, and pasta which reduced the 10-year diabetes risk by 40%, among participants aged 45-55 years. The association reached marginal statistical significance (95% CI: 0.34, 1.07), while no significant association was observed for the other age-groups. When the analysis was additionally adjusted for carbohydrate percentage, statistical significance was lost completely, suggesting a possibly mediating effect of this macronutrient. CONCLUSIONS: The results confirm the potentially protective effect of a plant-based dietary pattern in the primary prevention of diabetes, in particular among middle-aged people. Carbohydrate content may be a specific factor in this relationship; other micronutrients found in plant-based food groups may also play a role.

Worldwide type 2 diabetes (T2D) prevalence is increasing dramatically. The present study aimed to evaluate the association between dietary habits and T2D in an Iranian adult population using a cross-sectional analysis of the Shahedieh cohort study. Participants were adults aged 35-70 years (n 9261) from Zarch and Shahedieh, Yazd, Iran, who attended the baseline phase of the Shahedieh cohort study. Dietary habits including meal frequency, fried-food consumption, adding salt to prepared meals and grilled-food consumption were assessed by a standard questionnaire. T2D was defined as fasting plasma glucose (FPG) ≥126 mg/dl according to the American Diabetes Association. Multiple logistic regression assessed the association between dietary habits and T2D. Individuals who consumed a meal more than six times per day compared to three times per day had greater odds for T2D (OR 2⋅503, 95 % CI 1⋅651, 3⋅793). These associations remained significant in a fully adjusted model. There was a significant association between greater intakes of fried foods and prevalence of T2D (OR 1⋅294, 95 % CI 1⋅004, 1⋅668) in the adjusted model. No significant associations were observed between other dietary habits (adding salt to prepared meals and grilled-food consumption) and odds of T2D in all crude and adjusted models. In conclusion, we have highlighted the association between meal and fried-food consumption frequencies with risk of T2D. Large longitudinal studies in different ethnicities are needed to confirm these associations.

OBJECTIVE To summarise the evidence of associations between dietary factors and incidence of type 2 diabetes and to evaluate the strength and validity of these associations. DESIGN Umbrella review of systematic reviews with metaanalyses of prospective observational studies. DATA SOURCES PubMed, Web of Science, and Embase, searched up to August 2018. ELIGIBILITY CRITERIA Systematic reviews with meta-analyses reporting summary risk estimates for the associations between incidence of type 2 diabetes and dietary behaviours or diet quality indices, food groups, foods, beverages, alcoholic beverages, macronutrients, and micronutrients. RESULTS 53 publications were included, with 153 adjusted summary hazard ratios on dietary behaviours or diet quality indices (n=12), food groups and foods (n=56), beverages (n=10), alcoholic beverages (n=12), macronutrients (n=32), and micronutrients (n=31), regarding incidence of type 2 diabetes. Methodological quality was high for 75% (n=115) of meta-analyses, moderate for 23% (n=35), and low for 2% (n=3). Quality of evidence was rated high for an inverse association for type 2 diabetes incidence with increased intake of whole grains (for an increment of 30 g/day, adjusted summary hazard ratio 0.87 (95% confidence interval 0.82 to 0.93)) and cereal fibre (for an increment of 10 g/day, 0.75 (0.65 to 0.86)), as well as for moderate intake of total alcohol (for an intake of 12-24 g/day v no consumption, 0.75 (0.67 to 0.83)). Quality of evidence was also high for the association for increased incidence of type 2 diabetes with higher intake of red meat (for an increment of 100 g/day, 1.17 (1.08 to 1.26)), processed meat (for an increment of 50 g/day, 1.37 (1.22 to 1.54)), bacon (per two slices/day, 2.07 (1.40 to 3.05)), and sugar sweetened beverages (for an increase of one serving/ day, 1.26 (1.11 to 1.43)). CONCLUSIONS Overall, the association between dietary factors and type 2 diabetes has been extensively studied, but few of the associations were graded as high quality of evidence. Further factors are likely to be important in type 2 diabetes prevention; thus, more well conducted research, with more detailed assessment of diet, is needed.

Background: Diabetes is associated strongly with many neurodegenerative diseases and is also a lifestyle disorder. A good glycemic status depends on diet management and physical activity. There are several studies available on the relationship between diet habits and impact on diabetes. Purpose: The objective of this study was to check the association of different dietary factors with glucose levels and lipid values in type 2 diabetes from a part of a large nationwide trial. Methods: This was the data fromapan-India multicentered cluster randomized controlled study covering 60 states and 4 union territories; 17,285 individuals were surveyed for dietary factors. Amongst them, data of 12,500 individuals were analyzed.Males were 54% and 60% individuals were from urban areas. Results: The analysis of the results showed that consumption (usual/often) of milk(odds ratio, OR = 7.180), meat (OR = 6.81), less fiber (OR = 17.77), and less fruits (OR = 14.71) was strongly and positively associ...
Global epidemic of type 2 diabetes: implications for developing countries
Ethnicity & disease, 2003
Diabetes has reached epidemic proportions in many populations. Current estimates suggest that the number of persons with diabetes will reach 250 million by 2010 and 300 million by 2025. The majority of these patients will have type 2 diabetes and reside in developing countries. Type 2 diabetes and its associated long-term complications continue to accelerate among patients who reside in developing countries. Apart from microscopic complications, cardiovascular disease, with its attending morbidity and mortality, is on the rise in the developing countries. Current evidence suggests that environmental factors are major determinants of the increasing rates of diabetes. Addressing these environmental factors offers a unique opportunity for preventing diabetes; health programs that aim to encourage physical activity and discourage (or limit) overweight and obesity deserve significant attention. Prevention must be the cornerstone for international health organizations and ministries of he...
Generalizability of dietary patterns associated with incidence of type 2 diabetes mellitus
American Journal of Clinical Nutrition, 2009
Background: Reduced rank regression (RRR) has been used to derive dietary pattern scores that predict linear combinations of disease biomarkers. The generalizability of these patterns to independent populations remains unknown. Objective: The goal was to examine the generalizability of dietary patterns from the following prior studies using RRR to predict type 2 diabetes mellitus (T2DM): the Nurses' Health Study (NHS), European Prospective Investigation into Cancer and Nutrition Germany (EPIC), and Whitehall II Study (WS). Design: The relative weights of food groups of each dietary pattern were used to generate each dietary pattern score in the Framingham Offspring Study (n = 2879). Each of the external scores (confirmatory scores) was examined to determine whether it could predict incident T2DM during 7 y of follow-up as well as scores developed internally in the Framingham Offspring Study using a Coxproportional hazard model adjusted for T2DM risk factors. Results: Intakes of meat products, refined grains, and soft drinks (caloric and noncaloric) were found to be common predictive components of all confirmatory scores, but fried foods, eggs, and alcoholic beverages were predictive in some, but not in all, confirmatory scores. On the basis of a continuous increase in the score by 1 SD, the NHS-based confirmatory score predicted T2DM risk (hazard ratio: 1.44; 95% CI: 1.25, 1.66). However, T2DM risk was only weakly predicted by the EPIC-based score (hazard ratio: 1.14; 95% CI: 0.99, 1.32) and the WS-based score (hazard ratio: 1.16; 95% CI: 1.00, 1.35). Conclusions: The study suggested that dietary patterns that predict T2DM risk in different populations may not be generalizable to different populations. Additional dietary pattern studies should be conducted with regard to generalizability.
