Oxidative stress is recognized widely as being associated with various disorders including diabetes, hypertension, and atherosclerosis. It is well established that hydrogen has a reducing action. We therefore investigated the effects of hydrogen-rich water intake on lipid and glucose metabolism in patients with either type 2 diabetes mellitus (T2DM) or impaired glucose tolerance (IGT). We performed a randomized, double-blind, placebo-controlled, crossover study in 30 patients with T2DM controlled by diet and exercise therapy and 6 patients with IGT. The patients consumed either 900 mL/d of hydrogen-rich pure water or 900 mL of placebo pure water for 8 weeks, with a 12-week washout period. Several biomarkers of oxidative stress, insulin resistance, and glucose metabolism, assessed by an oral glucose tolerance test, were evaluated at baseline and at 8 weeks. Intake of hydrogen-rich water was associated with significant decreases in the levels of modified low-density lipoprotein (LDL) cholesterol (ie, modifications that increase the net negative charge of LDL), small dense LDL, and urinary 8-isoprostanes by 15.5% (P < .01), 5.7% (P < .05), and 6.6% (P < .05), respectively. Hydrogen-rich water intake was also associated with a trend of decreased serum concentrations of oxidized LDL and free fatty acids, and increased plasma levels of adiponectin and extracellular-superoxide dismutase. In 4 of 6 patients with IGT, intake of hydrogen-rich water normalized the oral glucose tolerance test. In conclusion, these results suggest that supplementation with hydrogen-rich water may have a beneficial role in prevention of T2DM and insulin resistance. 相似文献

The objective of this study is to examine the glycemic response to common Chinese foods in patients with type 2 diabetes. Twenty-four Chinese adults with type 2 diabetes participated. Subjects were allocated to eat a pair of test meals in random order. Test meals included plain porridge with lean pork (meal 1A), plain porridge and Shrimp Shao Mai (Doll Brand, Winner Food Products Limited, Hong Kong) (meal 1B), boiled rice with boiled egg white (meal 2A), fried rice with whole egg (meal 2B), plain noodles in clear soup (meal 3A), and Pickled Vegetable and Pork-flavored Instant Bowl Noodles (Doll Brand, Winner Food Products Limited) (meal 3B). Nutritional content of the meals was calculated from the nutritional label on the food package and the food composition table. Plasma glucose was checked before the meal and in 30-minute intervals for up to 4 hours after the meal. Significant differences in the area under the curve of glucose up to 2 hours after the meal were detected between meal 1A and 2A (P=.044), 1A and 3A (P=.001), and 3A and 3B (P=.017). The results suggest that fat alone does not alter the glycemic response to rice or porridge. Porridge produces a higher glycemic response than rice and noodles despite similar carbohydrate contents, and different noodles lead to differences in glycemic excursion, suggesting that the glycemic index of common Chinese foods is affected by cooking methods and food processing. 相似文献

BACKGROUND: Magnesium deficiency is common in type 2 diabetes and may have a negative impact on glucose homeostasis and insulin resistance, as well as on the evolution of complications such as retinopathy, thrombosis and hypertension. OBJECTIVE: To assess the dietary magnesium intake of patients with type 2 diabetes in Zurich, Switzerland and to compare the magnesium intake of diabetic and non-diabetic subjects. DESIGN: The magnesium intake of 97 randomly selected patients with type 2 diabetes and 100 healthy, non-diabetic controls matched for age and sex was estimated using a diet history method. During winter and summer periods, mean daily magnesium intakes were calculated from detailed information given by the test subjects about their eating habits over the previous 2 months. The calculations were performed using EBIS, a computer program based on a German nutrient data base (BLS 2.3), with food items specific to Switzerland added or directly analysed when necessary. RESULTS: The mean+/-s.d. daily magnesium intake of the male diabetic and male control subjects was 423.2+/-103.1 and 421.1+/-111.0 mg, respectively. The mean daily magnesium intake of the female diabetic and female control subjects was 419.1+/-109.7 and 383.5+/-109.7 mg, respectively. There were no significant differences in daily magnesium intake between the diabetic and the non-diabetic subjects and mean intakes in both groups exceeded Swiss recommended dietary intakes. CONCLUSIONS: Dietary intake of magnesium appears sufficient in Swiss adults with type 2 diabetes and is unlikely to contribute to the aetiology of magnesium deficiency.

The effect of 3-O-methyl-D-chiro-inositol (D-pinitol), purified from soybean, on the postprandial blood glucose response in patients with type 2 diabetes mellitus was examined. Fifteen Korean subjects with type 2 diabetes mellitus (seven men, eight women; 60.3 +/- 3.1 years old) ingested cooked white rice containing 50 g of available carbohydrate with or without prior ingestion of soy pinitol. Pinitol was given either as a 1.2 g dose at 0, 60, 120, or 180 minutes prior to rice ingestion, or as a 0.6 g dose at 60 minutes prior to rice ingestion. Capillary blood glucose levels were monitored for 4 hours after rice consumption. The ingestion of 1.2 g of pinitol 60 minutes prior to rice consumption controlled postprandial capillary blood glucose most effectively, significantly diminishing the postprandial increase in plasma glucose levels measured at 90 and 120 minutes after rice consumption (P < .05). The incremental area under the plasma glucose response curve for subjects who consumed both pinitol and rice was significantly lower than that for subjects who consumed only rice (P < .05), but pinitol had no apparent effect on postprandial insulin levels. Therefore, soybean-derived pinitol may be useful in controlling postprandial increases in blood glucose in patients with type 2 diabetes. 相似文献

BACKGROUND: Debate continues over the role of sucrose and sucrose-containing food in the diet for people with type 2 diabetes. Traditionally, dietary recommendations have suggested sucrose be reduced to a minimum level to improve glycaemic control. More recently the American Diabetes Association evidence-based guidelines have suggested a more liberal approach. OBJECTIVE: To investigate whether a 50 g increase in sucrose given as three slices of cake a day over a period of 24 days (88 +/- 7.5 g total sucrose/day) in combination with an increased monounsaturated fat intake (20% E) in line with current American Diabetes Association recommendations has an effect on glycaemic control or insulin sensitivity in people with type 2 diabetes. DESIGN: We re-examined results from a larger study that investigated the type of fat in the diet of people with type 2 diabetes. Nine overweight people with type 2 diabetes received a high-sucrose, high-monounsaturated-fat isocaloric diet for 24 days. Results Weight and glycaemic control remained stable throughout the study. There was no significant change in HbAlc over the study period. There was no change in insulin sensitivity, measured by the short insulin tolerance test. There was no change in fasting or postprandial incremental area under the curve in response to an identical standard test meal for glucose or insulin. CONCLUSIONS: Over the 3-week intervention period, an isocaloric increase in the dietary intakes of sucrose to 13% of total energy per day in people with type 2 diabetes was not associated with a decline in glycaemic control or insulin sensitivity. 相似文献

OBJECTIVE: This study examined baseline dietary intake, body weight, and physiologic status in patients enrolled in a dietary intervention for type 2 diabetes mellitus (T2DM). METHODS: Dietary, physiologic, and demographic information were collected at baseline from 40 adult patients with poorly controlled T2DM (glycosylated hemoglobin >7%) who participated in a clinical trial at an academic medical center in Worcester, Massachusetts, USA. RESULTS: The average age at enrollment was 53.5 y (SD 8.4), average body mass index was 35.48 kg/m(2) (SD 7.0), and glycosylated hemoglobin was 8.3% (SD 1.2). Participants were predominantly white, married, and employed full time. Forty-eight percent were men. Seventy-eight percent had hyperlipidemia, and 68% had hypertension. Reported baseline daily average energy intake was 1778 kcal (SD 814), daily carbohydrate was 159 g (SD 71.5), and dietary fiber was 11.4 g (SD 5.2). The dietary composition was 35% carbohydrate, 45% fat (15% saturated fat), and 20% protein. The American Diabetes Association (ADA) guidelines recommends 45-65% of energy from carbohydrate, 20-35% from fat (<7% saturated), and 20% from protein. CONCLUSION: These patients reported a low-carbohydrate, low-fiber, high-fat (especially saturated) diet, although they stated they are not following any of the popular low-carbohydrate diets. Patients with T2DM may find the current trend toward reducing weight through low-carbohydrate diets attractive for control of blood glucose, despite ADA recommendations. This dietary pattern may represent a popular trend that extends beyond our particular study and, if so, has serious cardiovascular implications in this vulnerable population of T2DM patients. 相似文献

Introduction: Type 2 diabetes is a major public health problem. Recent epidemiological evidence also points to a potential association of vitamin D insufficiency with adverse metabolic risks, including that for type 2 diabetes. Subjects and method: A double-blind randomized placebo-controlled trial was carried out. Seventy subjects with type 2 diabetes, age 30-75 years old, were randomly assigned in a double-blind fashion to two groups. One group received two capsules of calcitriol (0.25 μg 1,25-dihydroxy cholecalciferol per each capsule) per day. The second group received placebo tablets. At the beginning, middle and the end of the 12 week supplementation trial, serum glucose, insulin, calcium and phosphorous, HbA1c and 25(OH) vitamin D were measured. Results: There was no significant difference between two groups at baseline. At the end of the study, fasting plasma glucose increased in the control group (p=0.038), while it remained unchanged in calcitriol group. Level of insulin and HbA1c increased significantly in both groups (p=0.013 and 0.0004 in treatment and control group). Regarding insulin resistance indices, there was a significant change in HOMA-IR and QUICKI in both groups (p=0.023 and 0.002 in treatment and 0.001 and <0.001 in control group respectively). Insulin secretion as assessed by HOMA-%β, remained relatively unchanged in the control group, while it increased significantly in the treatment group at the end of study (p=0.009). Conclusion: Vitamin D supplementation attenuated the increase in glycemia, and increased insulin secretion, but had no effect on insulin resistance. 相似文献

The validity of baseline dietary intake data in women participating in a culturally competent intervention study for black women with type 2 diabetes was assessed. The relationship of sociodemographic and physiologic factors with underreporting of dietary intake was determined. Criterion validity of dietary intake, which had been assessed using the Nutritionist Five Collection Form, a combination of a standard 2-day dietary recall and a modified, culturally appropriate food frequency questionnaire, was determined. Data were analyzed using First Data Bank Nutritionist Five (version 2.3, 2000, First Data Bank, San Bruno, CA) software. Validation of baseline dietary data in 109 women was performed by calculating the ratio of energy intake to resting metabolic rate. Chi(2) and t tests were used to assess relationships between underreporting and sociodemographic and physiologic factors. Mean ratio of energy intake to resting metabolic rate was 1.46 (+/-0.4). Using a lower limit of 1.35, the prevalence of underreporting was 46.8%. Underreporting was significantly associated with body mass index (P< or =0.001) and waist circumference (P<0.001). Use of this combined dietary recall and modified food frequency questionnaire might, therefore, provide more accurate dietary assessment in this population. Additional modification and validity testing is warranted in this and other populations. 相似文献
